ScREAM testing - Githubissues

balazskreith commented 7 years ago

Hi,

I am using screamqueue for testing purpose. The implementation for the sender and for the receiver part can be found respectively at: scream_sender and at scream_receiver.

For network simulation I use linux network namespaces, tc and qdisc for bandwidth changing. The base RTT is 200ms. I migrated the rtcp feedback setup and other code necessary for scream implementation from the current openwebrtc code (owr_transport_agent object)

Meanwhile I am testing it I have struggled the problem of insufficient MAX_TX_PACKETS due to the refresh interval of incoming_packets in the src_loop function, lead the program into a segfault after a certain amount of time and warning. I increased the MAX_TX_PACKETS value to 2000, but its still seems to be insufficient for a network channel with 3000kbit/s bandwidth.

Did I missed something in my implementation or do I need to change something?

Hi The fact that the MAX_TX_PACKETS is not sufficient indicates that the RTCP feedback is not functioning properly. Have you verified that the RTCP feedback is received on the sender side ?

I receive FB message with the type of GST_RTCP_RTPFB_TYPE_SCREAM. Messages are received in [20,100]ms interval. I emitting the signal incoming-feedback and giving the appropriate parameters to it. It approve packets and the is_used boolean indicator set to false after a certain amount of time, but its not enough.

incoming_packets async queue inside of screamqueue object contains GstScreamDataQueueRtpItem and GstScreamDataQueueRtcpItem type items. These items are processed at gst_scream_queue_srcpad_loop, albeit GstScreamDataQueueRtcpItem processed much slower than it should be.

I have printed out events refer to incoming_packets queue at gst_scream_queue_srcpad_loop. the line elapsed shows the us elapsed between two popout from the queue in the function and line starts by rtcp_item pushed indicate an rtcp push event happens at gst_scream_queue_incoming_feedback.

Although the latest rtcp_item pushed inside incoming_packets contains HSSN 11214, the latest processed rtcp_item popped out from incomin_queue shows the HSSN it processes 11153. After a time shift between the rtcp_item should be processed and the rtcp_item processed becoming larger and the MAX_TX_PACKET is going to be hit. Any idea what can cause this?

IngJohEricsson commented 7 years ago

OK, seems to me that somehow the received feedback is not anyway forwarded to the SCReAM algorithm. There is a GST_INFO log in gstscreamcontroller, could you please run with this log enabled for ~10 seconds and post the result ? Given this log it can be easier to determine what is wrong.

Hi,

Thank you for your answer. I know I can produce debug logs by running the following command: GST_DEBUG=screamqueue:5 ./scream_sender

How should I run scream_sender to produce the logfile you requested?

I have printed out logs from gstscreamcontroller. Here it is:

Hi

Thanks for the log There is definitely something wrong

1) : The line below does not make much sense Target br adj : T= 1.189s target(actual)= 119( 89, 83, 0)k rtpQ= 20ms cwnd= 4202(147705) srtt=2489ms owd(T)= 40(100)ms fs=1 dt=4360

dt = 4360 indicates that it is 4360ms since the last received feedback, a bit odd as the time is 1.189s, don’t understand this. The srtt is also very high (over 2seconds). In addition,, the “( 89, 83, 0)” part indicates that the acknowledged rate is zero, this makes me suspect that there is no incoming feedback to gst_scream_controller_incoming_feedback Could you add an extra log item in this function to verify this ?

2) : Tried to locate where the logs below occur, is it on the receiver side or on the sender side ? rtcp_item pushed m_ssrc: 2644692479 | ts: 5909 | HSSN: 851 | loss: 1 | n_ecn: 0 | qbit: 0 This log item looks sensible as far as I can see, so if this feedback reaches gst_scream_controller_incoming_feedback then it should work ?

3): The log message “Too many bytes in flight” on line 559 in gstscreamcontroller is misleading, what actually happens is that there are no packets available in the RTP queue.

Thank you for the quick reply.

The test itself is totally unidirectional media flow and the logs I copied generated by the sender side.

gst_scream_controller_incoming_feedback has not receive the feedback since it is called at gst_scream_queue_srcpad_loop, which is acquire the items from the incoming_packet queue.

I have also observed the problem with srtt, which shouldn't be so high. I made a ping and got:

64 bytes from 10.0.0.6: icmp_seq=1 ttl=63 time=200 ms 64 bytes from 10.0.0.6: icmp_seq=2 ttl=63 time=200 ms 64 bytes from 10.0.0.6: icmp_seq=3 ttl=63 time=200 ms

I added a probe at the receiver side responsible for exemining all rtp packets going to rtpbin. That was clear, and that probe fnc is the probe_rtp_info https://github.com/multipath-rtp/gst-mprtp/blob/master/tests/scream_receiver.c#L290.

In that, rtp_session is also set to generate feedback in every 20ms. The RTP profile is set to AVPF to rtpbin, reduced-rtp-size also allowed and set. on_sending_rtcp https://github.com/multipath-rtp/gst-mprtp/blob/master/tests/scream_receiver.c#L403. feedback is assembled. Here I do not understand why ack_vec is not part of the feedback, which according to the scream rfc draft it should be (by the way your latest presentation about scream the feedback interval is changed to 5packets is it implemented into this or is it waiting for being inside of public?). Also I do not understand where the timestamp field are added to the feedback according to the RFC3611, necessary for autocorrelation calculation at the sender side. Also I do not see where the timestamp calculated at the receiver side.

What is not clear to me, is that why I need to add add_ts

Hi

Thanks for the log There is definitely something wrong

1) : The line below does not make much sense Target br adj : T= 1.189s target(actual)= 119( 89, 83, 0)k rtpQ= 20ms cwnd= 4202(147705) srtt=2489ms owd(T)= 40(100)ms fs=1 dt=4360

dt = 4360 indicates that it is 4360ms since the last received feedback, a bit odd as the time is 1.189s, don’t understand this. The srtt is also very high (over 2seconds). In addition,, the “( 89, 83, 0)” part indicates that the acknowledged rate is zero, this makes me suspect that there is no incoming feedback to gst_scream_controller_incoming_feedback Could you add an extra log item in this function to verify this ?

2) : Tried to locate where the logs below occur, is it on the receiver side or on the sender side ? rtcp_item pushed m_ssrc: 2644692479 | ts: 5909 | HSSN: 851 | loss: 1 | n_ecn: 0 | qbit: 0 This log item looks sensible as far as I can see, so if this feedback reaches gst_scream_controller_incoming_feedback then it should work ?

3): The log message “Too many bytes in flight” on line 559 in gstscreamcontroller is misleading, what actually happens is that there are no packets available in the RTP queue.

I have printed out logs from gstscreamcontroller. Here it is:

Hi

Comments inline, marked [IJ] /Ingemar

From: Balázs Kreith [mailto:notifications@github.com] Sent: den 24 augusti 2016 22:41 To: EricssonResearch/openwebrtc-gst-plugins openwebrtc-gst-plugins@noreply.github.com Cc: Ingemar Johansson S ingemar.s.johansson@ericsson.com; Comment comment@noreply.github.com Subject: Re: [EricssonResearch/openwebrtc-gst-plugins] ScREAM testing (#54)

Thank you for the quick reply.

The test itself is totally unidirectional media flow and the logs I copied generated by the sender side.

gst_scream_controller_incoming_feedback has not receive the feedback since it is called at gst_scream_queue_srcpad_loop, which is acquire the items from the incoming_packet queue. [IJ] As I understand it then, the problem is that the feedback is lost somehow. This will cause the RTP packet transmission to stall. SCReAM has a built in timeout mechanism that transmits an RTP packet every 200ms even though no feedback is received, this is to be able to kickstart the self-clocking loop in SCReAM in case there has been a temporary outage, the effect is that one will see that the rendered video will change every 2-5s even though feedback is missing.

I have also observed the problem with srtt, which shouldn't be so high. I made a ping and got:

64 bytes from 10.0.0.6: icmp_seq=1 ttl=63 time=200 ms 64 bytes from 10.0.0.6: icmp_seq=2 ttl=63 time=200 ms 64 bytes from 10.0.0.6: icmp_seq=3 ttl=63 time=200 ms [IJ] This is probably a side effect of the lost feedback

I added a probe at the receiver side responsible for exemining all rtp packets going to rtpbin. That was clear, and that probe fnc is the probe_rtp_info https://github.com/multipath-rtp/gst-mprtp/blob/master/tests/scream_receiver.c#L290.

In that, rtp_session is also set to generate feedback in every 20ms. The RTP profile is set to AVPF to rtpbin, reduced-rtp-size also allowed and set. on_sending_rtcp https://github.com/multipath-rtp/gst-mprtp/blob/master/tests/scream_receiver.c#L403. feedback is assembled. Here I do not understand why ack_vec is not part of the feedback, which according to the scream rfc draft it should be (by the way your latest presentation about scream the feedback interval is changed to 5packets is it implemented into this or is it waiting for being inside of public?). Also I do not understand where the timestamp field are added to the feedback according to the RFC3611, necessary for autocorrelation calculation at the sender side. Also I do not see where the timestamp calculated at the receiver side. [IJ] It is written to the RTCP packet on line 3015 in owr_transport_agent.c And is calculated on line 4362 in the same module The OWR implementation is not the same as described in the draft, the OWR implementation computes an accumulated lost packets counter, this is changed to an ACK vector in the draft and in the C++ implementation (https://github.com/EricssonResearch/scream ) as it makes it easier to make loss detection robust to packet reordering, also I wanted to have as much of the intelligence as possible on the sender side. The C++ implementation and the IETF draft match one another very well, the OWR implementation lags behind a little I am afraid. One solution would be to replace the OWR implementation with the C++ implementation.

What is not clear to me, is that why I need to add add_ts [IJ] Not sure what you mean, you mean the receive timestamp ?

Hi

Thanks for the log There is definitely something wrong

1) : The line below does not make much sense Target br adj : T= 1.189s target(actual)= 119( 89, 83, 0)k rtpQ= 20ms cwnd= 4202(147705) srtt=2489ms owd(T)= 40(100)ms fs=1 dt=4360

dt = 4360 indicates that it is 4360ms since the last received feedback, a bit odd as the time is 1.189s, don’t understand this. The srtt is also very high (over 2seconds). In addition,, the “( 89, 83, 0)” part indicates that the acknowledged rate is zero, this makes me suspect that there is no incoming feedback to gst_scream_controller_incoming_feedback Could you add an extra log item in this function to verify this ?

2) : Tried to locate where the logs below occur, is it on the receiver side or on the sender side ? rtcp_item pushed m_ssrc: 2644692479 | ts: 5909 | HSSN: 851 | loss: 1 | n_ecn: 0 | qbit: 0 This log item looks sensible as far as I can see, so if this feedback reaches gst_scream_controller_incoming_feedback then it should work ?

3): The log message “Too many bytes in flight” on line 559 in gstscreamcontroller is misleading, what actually happens is that there are no packets available in the RTP queue.

Hi,

I have identified the problem occurs at gst_scream_queue_srcpad_loop by pushing approved packets at gst_pad_push line. In my pipeline it took 40ms and blocks this thread preventing it for processing the incoming_packets commands executed after it sends the approved one. In this 40ms blocks the incoming_packets queue is built up and shift between sent packets and processed feedbacks become larger and larger.

This blocking cause by the udpsink in the sender pipeline and not related to scream algorithms. I changed the udpsink sync property FALSE and, but then the adjusted target rate fluctuating very much, due to the owd fluctuation. The owd is ensured by netem that its 100ms and the rtt is 200ms. I got the following results produced by scream calculation.

As you see rtpQ has been building up suddenly.

What would be the appropriate separation gst element or properties between scream_queue and a simple udpsink (I saw in OWR this is solved by nice_sink, but in a simple pipeline I forked from rtpaux_server I would like to solve it by using udpsink and udpsrc)
Why the reduction of the rate so much? (it drops from 1.2Mbit/s to 64000bit/s)

Hi

OK, seems like the first problem is solved, great ! See that the feedback rate is a bit low the first 4 seconds and that can cause the video to become choppy. I observe from the log that the actual video coder output rate is considerably higher than the target rate. For instance the line below says that the output rate from the codec is 6189kbps, i.e 8 times larger than the target. This works as long as the link is not congested, however at T= 6.882s the link becomes congested and SCReAM starts to limit the send rate. The effect is that the rtp packet queue will quickly build up. The problem is thus that the video coder target rate is not set properly, seems like the video coder output rate is always some 5 to 8 times larger than the target rate.

PS, the rate reading is given by the target(actual)= 857(6189,4804,4465)k. The syntax is target(actual)= target(actual_codec_rate,transmitted_rate,acked_rate)k With this example: Target_rate = 857kbps Actual_coded_rate= 6189kbps Transmitted_rate = 4804kbps Acked_rate = 4465kbps

Hi,

I have identified the problem occurs at gst_scream_queue_srcpad_loop by pushing approved packets at gst_pad_pushhttps://github.com/EricssonResearch/openwebrtc-gst-plugins/blob/master/gst/scream/gstscreamqueue.c#L504 line. In my pipeline it took 40ms and blocks this thread preventing it for processing the incoming_packets commands executed after it sends the approved one. In this 40ms blocks the incoming_packets queue is built up and shift between sent packets and processed feedbacks become larger and larger.

This blocking cause by the udpsink in the sender pipeline and not related to scream algorithms. I changed the udpsink sync property FALSE and, but then the adjusted target rate fluctuating very much, due to the owd fluctuation. The owd is ensured by netem that its 100ms and the rtt is 200ms. I got the following results produced by scream calculation.

As you see rtpQ has been building up suddenly.

What would be the appropriate separation gst element or properties between scream_queue and a simple udpsink (I saw in OWR this is solved by nice_sink, but in a simple pipeline I forked from rtpaux_server I would like to solve it by using udpsink and udpsrc)
Why the reduction of the rate so much? (it drops from 1.2Mbit/s to 64000bit/s)

If it had been exactly 8 times higher or lower than I would have said a bits to byte convert is missing somewhere.

I tested the scream_sender by using testvideosrc, the result is in that case the target is higher than the acknowledged rate. For the former test I used the foreman_cif raw file. Can it cause that the vector length confirming the rate in screamqueue is not sufficiently long? Why it happens that the same pipeline once get higher acknoeldged bitrate than it should have if I use foreman_cif and lower acknowledged bitrate if I use testvideosrc?

Below the adjusted bitrates with testvideosrc

Hi

I only did the testing with a real webcamera, did not try with raw files. Anyway, somehow the video coder rate does not map sufficiently with the target rate, it is inevitable that the coder rate oscillates around the target rate and occasionally becomes 2-5 times higher because of e.g. full intras but a persistent 5-8 times to high is not correct. Can you try with a webcam ?

If it had been exactly 8 times higher or lower than I would have said a bits to byte convert is missing somewhere.

I tested the scream_sender by using testvideosrc, the result is in that case the target is higher than the acknowledged rate. For the former test I used the foreman_cif raw file. Can it cause that the vector length confirming the rate in screamqueue is not sufficiently long? Why it happens that the same pipeline once get higher acknoeldged bitrate than it should have if I use foreman_cif and lower acknowledged bitrate if I use testvideosrc?

Below the adjusted bitrates with testvideosrc

Here is the pipeline for video (I know caps missing):

static SessionData *
make_video_session3 (guint sessionNum)
{
  GstBin *videoBin = GST_BIN (gst_bin_new (NULL));
  GstElement *v4l2src = gst_element_factory_make ("v4l2src", NULL);
  GstElement *queue = gst_element_factory_make ("queue", NULL);
  GstElement *videoconvert = gst_element_factory_make ("videoconvert", NULL);
  GstElement *capsfilter = gst_element_factory_make ("capsfilter", NULL);
  GstElement *payloader = gst_element_factory_make ("rtpvp8pay", NULL);
  GstCaps *videoCaps;
  SessionData *session;

  encoder = gst_element_factory_make ("vp8enc", NULL);
  g_object_set (encoder, "target-bitrate", sending_target, NULL);

  g_object_set(encoder,
        "end-usage", 1, /* VPX_CBR */
        "deadline", G_GINT64_CONSTANT(1), /* VPX_DL_REALTIME */
        "cpu-used", -6,
        "min-quantizer", 2,
        "buffer-initial-size", 300,
        "buffer-optimal-size", 300,
        "buffer-size", 400,
        "dropframe-threshold", 30,
        "lag-in-frames", 0,
        "timebase", 1, 90000,
        "error-resilient", 1,
  //      "keyframe-mode", 1, /* VPX_KF_DISABLED */
  //      "keyframe-max-dist", 128,
        NULL);

  gst_bin_add_many (videoBin, v4l2src, videoconvert, queue, encoder, payloader, NULL);
  videoCaps = gst_caps_new_simple (
      "video/x-raw",
      "width", G_TYPE_INT, 352,
      "height", G_TYPE_INT, 288,
      "framerate", GST_TYPE_FRACTION, 25, 1, NULL);

  gst_element_link_many (v4l2src, videoconvert, queue, encoder, payloader, NULL);

  setup_ghost (payloader, videoBin);

  session = session_new (sessionNum);
  session->input = GST_ELEMENT (videoBin);

  return session;
}

Here is the output:

Hi

It seems like the feedback rate is very low with intervals in the order to 200ms or even more. It could also be that you should perhaps at least initially set the min RTT to e.g 50ms, at least as long as you debug this. The low feedback rate will definitely cause problems, the effect will be that it may not be possible to reach higher bitrates because the ack-clocking becomes limited by the low feedback rate.

Here is the pipeline for video (I know caps missing):

Hi,

I have checked the feedbackrate, printed out each time it receives one, the average rate is 20ms, the rate adjust is 200ms what is set in the screamcontroller. Now I am using videotestsrc produces the source. The observed throughput changes regarding to test RMCAT1 are plotted and attached to this comment.

Hi And thanks for trying out SCReAM. It looks almost like it should, see however that the bitrate drops down very much when the bottleneck shrinks. I saw behavior like this when I developed SCReAM, I suspect that the internal video coder rate control loop is a bit sluggish, meaning that it takes a bit too long for the output bitrate to be reduced when the target bitrate drops. It can here be good to plot the target bitrate and the output bitrate from the video coder (available in the logs) and see the response time. I recall that some changes had to be done to OpenH264 parameters to make it sufficiently responsive to target rate changes, the same was also the case with VP8. I believe that with the parameter changes the response time for the video coder was down to ~300ms, without the changes it was almost 1 second.

Hi,

The problem seems to be solved, I would like to say thank you for your quick replies, help and guidance.

Hi Ok, thanks for trying it out, the video encoder interaction has been quite tricky to tackle. Did you get it to perform better on the RMCAT test case ?

Hi

Sometimes yes, sometimes not so. (I attached two test results, in one the SCReAM shrinks just like it should be, in the other it reaches the minimum sending rate).

At the hard drop of the bottleneck in test RMCAT1, I have experienced that cwnd_update reacts slightly later then the target adjust mechanism. For an instance, here at the drop moment (40s) the target is reduced sooner than the cwnd. (Note, the line T: %f | cwnd: %u (%u) | newly_acked: %u) means: seconds since the last cwnd_update, cwnd itself, cwnd_i, newly acked bytes)

So here, cwnd reduced slightly later than the target. At deflate process what packets found in the rtpQ you clear it or transfer it?

Hi

And sorry for the delayed response. A few answers inline below /Ingemar

Hi

Sometimes yes, sometimes not so. (I attached two test results, in one the SCReAM shrinks just like it should be, in the other it reaches the minimum sending rate).

[IJ] Yes, the peer1_owd_1_result50_1.pdfhttps://github.com/EricssonResearch/openwebrtc-gst-plugins/files/444949/peer1_owd_1_result50_1.pdf looks quite OK while the other one looks a bit worse.

At the hard drop of the bottleneck in test RMCAT1, I have experienced that cwnd_update reacts slightly later then the target adjust mechanism. For an instance, here at the drop moment (40s) the target is reduced sooner than the cwnd. (Note, the line T: %f | cwnd: %u (%u) | newly_acked: %u) means: seconds since the last cwnd_update, cwnd itself, cwnd_i, newly acked bytes)

[IJ] Yes, that is correct, it is done like this on purpose, the reason is that delay spikes can occur for odd reasons such as handover in LTE, it is not desired to allow the congestion window react too much to this, for this reason the cwnd adjustment is a bit slower than the video rate adjustment. I believe that the root cause the problem is that the video rate control loop is a bit too slow, one can see that it lags behind the target rate with some 600ms. The SCReAM rate controller reacts on that the rtpQ builds up and tries to push down the target rate even some more. The suggested solutions to this is first of all to try to make the video coder more reactive to target rate changes, which video coder is this ? If this does not help then try and change TX_QUEUE_SIZE_FACTOR in gstscreamcontroller.c to 0.5 or perhaps lower.

So here, cwnd reduced slightly later than the target. At deflate process what packets found in the rtpQ you clear it or transfer it?
