4 years ago Hi @mikaelsson , what's your command line?
From the log, you are using CQP bitrate control. I didn't see the target bitrate setting.
SVT [config]: BRC Mode / QP / LookaheadDistance / SceneChange : CQP / 32 / 17 / 1

4 years ago hi @tianjunwork,
CQP bitrate control was on by default. I switched to VBR mode and now I am getting at least 7-9 mbps according to log and correct 10 mbps according to mediainfo (which is a bit strange, but it is not the issue), the main issue remains: there is still no video in output.
I am running ffmpeg from the script-file (updated for vbr mode and added gop_size parameter):
#!/bin/bash

4 years ago Thank you sending the test result. The no video issue is not related to svt ffmpeg plugin.
I am not an expert of using ffmpeg udp output. Maybe you could try increase buffer_size?
buffer_size=size
Set the UDP maximum socket buffer size in bytes. This is used to set either the receive or send buffer size, depending on what the socket is used for. Default is 32 KB for output, 384 KB for input. See also fifo_size.I am sorry, but I must disagree with you. I believe it has something to do with the plugin, simply because if I change libsv_hevc to libx265 (and remove -rc 1 because it is not valid for libx265) everything works. well not quite due to the fact that it can't reach 60fps even on this system, and because of that timing is a bit scewed. But it is "playable". I also tested libx264 just with different stream and streaming to network is not an issue in any of these cases.
libx265 script:
#!/bin/bash
ffmpeg -ignore_unknown -sn -c:v hevc -i "udp://@224.0.0.1:1234?overrun_nonfatal=1&fifo_size=2788760" \

4 years ago Add the plugin owner @guojiansheng0925. Hi Jiansheng, to sum up, the ffmpeg plugin works if writes to local file but not udp destination. Could you take a look? Thank you. Hi @mikaelsson , Please expect a delay in responses since it is holiday for Jiansheng.

4 years ago Hi @mikaelsson , I have tried to reproduce the issue with flowing steps:
1) first terminal: produce stream with FFmpeg on my local machine
ffmpeg -re -i ../../content/oceans.mp4 -vcodec copy -f mpegts udp://127.0.0.1:1234
2) second terminal:
ffmpeg -ignore_unknown -sn -c:v h264 -i "udp://127.0.0.1:1234" -c:v libsvt_hevc -s 960x400 -r 60 -g 60 -b:v 10000k -c:a copy -flush_packets 0 -f mpegts "udp://127.0.0.1:4321"
3) third terminal: play with FFplay
ffplay -protocol_whitelist "file,udp,rtp" -i udp://127.0.0.1:4321
It can reproduce the no video issue, and second terminal always said
Too many packets buffered for output stream 0:1. Conversion failed!
And we can use the parameter - -max_muxing_queue_size 1024 to solve it. https://stackoverflow.com/questions/49686244/ffmpeg-too-many-packets-buffered-for-output-stream-01
I am not sure if we are in the same environment and could you please try the parameter -max_muxing_queue_size? Thank you.

}Hi @mikaelsson , I am sorry I can't reproduce this issue on my local environment.
Could you please have a try to use a local file to produce the stream via udp, like this:
ffmpeg -re -i ../../content/oceans.mp4 -vcodec copy -f mpegts udp://127.0.0.1:1234
And then use your FFmpeg string to see if there is no video.
or
Could you tell me how is your input produced ( udp://@224.0.0.1:1234?overrun_...) May I use it or may I reproduce a similar stream?
Thank you.

First is taken from a file generated by ffmpeg's report function. But for some reason it ommited svt-plugin's version part in log (probably has something to do with the fact that ffmpeg outputs to stderr and svt to stdout). Because of that I include the log of the next run too, but copied directly from the terminal window.

Press any key to continue...Hi @mikaelsson , I am sorry I still can not reproduce the issue. I suggest we should sync the environment for the further analysis. Simplify the environment as much as possible. Prepare a yuv file and FFmpeg on your own computer to remove the influence of other potential issues. Could you please do as the following step strictly?
Step 0: build the FFmpeg with the configuration
--enable-gpl --enable-libsvthevc --enable-libx265
Step 1: Generate the ts file from the yuv
(I tried with cars.yuv, repeated command cat cars.yuv>>cars_long.yuv to make it more than 1000 frames).
ffmpeg -s 1280x720 -i cars_long.yuv -c:v libx265 cars265.ts
Step2:
ffmpeg -re -i cars265.ts -vcodec copy -f mpegts udp://127.0.0.1:1234
Step3:
ffmpeg -ignore_unknown -sn -c:v hevc -i "udp://127.0.0.1:1234" -c:v libsvt_hevc -s 1280x720 -r 60 -g 60 -b:v 10000k -c:a copy -flush_packets 0 -f mpegts "udp://127.0.0.1:4321" -max_muxing_queue_size 1024
Step 4:
ffplay -protocol_whitelist "file,udp,rtp" -i udp://127.0.0.1:4321
Wait a moment and check if the above command can reproduce the issue.
cars_1280x720.h264.txt
The attached file is my test sequence, you can remove the txt suffix and decode it to get the yuv file I used.
ffmpeg -c:v h264 -i cars_1280x720.h264 cars.yuv
Thanks.

4 years ago Hi @guojiansheng0925 ,
I did the steps (almost all), and since we are talking about environment, maybe the following info will be helpful in some way:
I am running this setup on HPE Proliant dl380 g10 with Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz. Only things disabled are virtualization and hyperthreading.
also Red Hat Enterprise Linux release 8.1 (Ootpa) with 4.18.0-147.5.1.el8_1.x86_64 kernel.
sysctl:
# Maximum receive socket buffer size
net.core.rmem_max = 67108864
# Maximum send socket buffer size
net.core.wmem_max = 67108864
# Default receive socket buffer size
net.core.rmem_default = 67108864
# Default send socket buffer size
net.core.wmem_default = 67108864
# The number of pages allowed for queueing by all UDP sockets
net.ipv4.udp_mem = 8388608 16777216 33554432
# Minimum, initial and max TCP receive buffer
net.ipv4.tcp_rmem = 4096 87380 33554432
# Minimum, initial and max TCP send buffer
net.ipv4.tcp_wmem = 4096 65536 33554432
kernel.sched_rt_runtime_us = 1000000this last setting taken from here: https://github.com/OpenVisualCloud/SVT-HEVC/blob/master/Docs/svt-hevc_encoder_user_guide.md

4 years ago Hi @mikaelsson ，
I tried use ffprobe and get the same result.
It doesn't matter it can be played well with ffplay and vlc on my machine (ubuntu18.04) .
This result is caused by losing head information, we can adjust the order of command execution to avoid this.
ffmpeg -ignore_unknown -sn -c:v hevc -i "udp://127.0.0.1:1234" -c:v libsvt_hevc -s 1280x720 -r 60 -g 60 -b:v 10000k -c:a copy -flush_packets 0 -f mpegts "udp://127.0.0.1:4321" -max_muxing_queue_size 1024
ffprobe -i "udp://127.0.0.1:4321"
and push the stream at last:
ffmpeg -re -i cars265.ts -vcodec copy -f mpegts udp://127.0.0.1:1234
And then there won't be warnings in ffprobe:

Let's come back to the no video issue, could you please try to play it? I think it is easy to compile FFmpeg on your personal computer. Or you may try to use other media player to play the result on your server.
Thanks.

4 years ago Forgive me if this is entirely unrelated to the issue you are discussing, but I'll offer it anyway just in case it helps:
I have a video streaming server built using the FFmpeg libraries and as of yesterday I added SVT-HEVC support. I take raw audio and video data (captured) and use the FFmpeg libraries to encoder both streams and produce an mpeg-ts output.
I found that the DTS of the packets generated by SVT-HEVC starts from near zero (slightly negative actually, depending on configuration) rather than values similar to the input data PTS and I found this screwed up the interleaving of the audio and video packets in the mpeg-ts. This led to my video player application being unable to correctly playback the stream.
My app also uses NVENC and I noticed that the DTS values that FFmpeg outputs when using NVENC-HEVC are similar to the PTS values.
So I made a small change to the SVT-HEVC FFmpeg plugin so that it stores the the PTS of the first frame submitted to encode, and adds this as an offset to all the DTS of the packets that gets output.
This fixed my issue and it then behaved the same as NVENC.
I just wonder if in the issue described in this thread it might be caused by the same thing - maybe when the packets are chucked straight to UDP the DTS is still "wrong" whereas when FFmpeg produces a file from it maybe it "corrects" them as it writes them or something.

4 years ago @tianjunwork here is a drop-in replacement for the libsvt_hevc.c file which is the same as the one here in your repo plus my modification.
https://ovcollyer.synology.me:5001/d/f/553688144730438077
However, I think if this is a legitimate issue then it would be better to fix it inside the SVT-HEVC code itself. I can see there is already another fix in the gstreamer plugin which works around negative DTS values. If DTS was rebased from PTS in the SVT-HEVC code then neither of these workarounds in the plugins would be necessary.
tianjunwork

4 years ago Hi @oviano, thank you for sharing it:) Agree. We will investigate SVT-HEVC itself if any change could be made. @mikaelsson , could you try oviano's libsvt_hevc.c to see if your issue be possibly fixed?

4 years ago So interestingly since my fix for the DTS issue, I've found that I am able to intermittently repeat something that seems close to the issue being reported here; my server appears to encode correctly using SVT-HEVC (I mean, there are no errors reported by the FFmpeg libraries) but I get the following trace in my playing application:

This happens around maybe 25-50% of the time when encoding a 1280x720 stream using SVT-HEVC. I haven't managed to make it happen with an 1920x1080 encode.
I also raised the "max_analyze_duration" period from 7s to 30s, but it still produces the same issue.
Conclusion: the issue reported here probably isn't related to the DTS issue I noticed, instead there seems to be certain conditions which cause SVT-HEVC to construct in an incorrect elementary stream.

4 years ago hi @tianjunwork , @oviano , @guojiansheng0925 First of all thank you, @oviano, for your patch. I tried it but unfortunatelly I did not notice any difference.
Now the good news. I tried to the procedure backwards as @guojiansheng0925 proposed in his previous post. So if I start ffprobe or multicat BEFORE transcoding, then I get the complete information with resolution and everything. If I start it after starting transcoding, I get the same stuff like I described in my previous posts. for example: started ffprobe, started transcoding, ffprobe outputs correct info and exits, instantly launch ffprobe again and it outputs info without video resolution.
I made small recordings to check the playback. Oviano's patch was not used while making these.
naming contains the order in which components were launched: mc
multicat -u -U @224.0.0.2:4321 str_tr_mc.tsstr
ffmpeg -re -i cars265.ts -vcodec copy -f mpegts udp://224.0.0.1:1234tr

4 years ago Ok, that's interesting and suggests to me that the problem is when joining the MPEG-TS stream after the start.
To back-up this theory I am able to get a 100% reproduction rate in my code when I join a second player to my server after the stream has started.
So without fully understanding the internals of this sort of stuff it looks to me as if the SVT-HEVC elementary stream is missing some information (or incorrectly writing something) that would usually be periodically resent by the MPEG-TS packetizer to allow a client to join the stream at any point (which is of course the point of an MPEG-TS stream).
oviano
commented
4 years ago I wonder if we were to encode a TS file of let’s say 60s long and then chopped it in half into two files whether the second file would have the same issue.
I might try it tomorrow.
oviano
commented
4 years ago So as I suspected, the same issue occurs if you take a TS file and cut it in half.
Here is a TS file encoded using svt-hevc using ffmpeg:
https://ovcollyer.synology.me:5001/d/f/554222187444222691
Here is the same file split roughly at the halfway point:
1st: https://ovcollyer.synology.me:5001/d/f/554233652333035042 2nd: https://ovcollyer.synology.me:5001/d/f/554233118186322869
The first half plays correctly in VLC, but the second-half produces audio only consistent with the issue described in this thread. This is of course not expected or desired behaviour in an mpeg-ts stream.
I have never seen this issue with mpeg-ts files that were produced using nvenc-hevc, nvenc-h264, x265 or x264 so I presume it must be a bug in the elementary stream that svt-hevc generates which means that it doesn't work properly with mpeg-ts.

4 years ago Hi @mikaelsson @oviano @tianjunwork ,
Let's start with my conclusion: 1) It can be played well in the case of the player receive all the information of the stream. 2) If we start playing it in the half of the stream encoded by svt-hevc, the video can not be played.
It may be a feature of svt-hevc, not a bug.
As we know, hevc bit stream is consist of NAL Units：
The IDR frame, SPS and PPS are necessary for playing. When we start playing in the middle of a hevc bit stream, it will be played well after received the next IDR frame.
But in the case of svt-hevc, there is only one IDR frame at the front of the bit stream.
I said it is a feature because we it was written in the section 5.1 of user guide. https://github.com/OpenVisualCloud/SVT-HEVC/blob/master/Docs/svt-hevc_encoder_user_guide.md#hierarchical-coding-structure-parameters
No more I frames in both LowDelay and Random-Access mode.
I can't reproduce the issue because I create the ts stream by :
ffmpeg -s 1280x720 -i cars.yuv -c:v libx265 cars265.ts
The no video issue can be reproduced when using libsvt_hevc:
ffmpeg -s 1280x720 -i cars.yuv -c:v libsvt_hevc cars265.ts
@oviano , the trace you mentioned:
Error parsing NAL unit #1. PPS id out of range: 0 PPS id out of range: 0
is caused by losing header information (SPS PPS IDR), the decoder can't parsing the following NAL Units.
So we should start the player and run the processing command firstly, then start to push the stream.
Thanks.
oviano
commented
4 years ago The workaround of starting the stream first would not work in the case of, for example, broadcast TV where the TS is constantly being broadcast.
In this case, any set top box attempting to tune into the broadcast would not work if the stream had been encoded using SVT-HEVC because it would never receive the stream header.
Is there an option to send repeated IDR frames - would IntraRefreshType set to a positive value solve it?
guojiansheng0925
commented
4 years ago Hi @oviano ,
I have tried some parameters but there is still only one IDR frame.

4 years ago I’m curious as to how live streaming could work with SVT if it’s necessary to receive the start of the stream.
Regardless of the container, whether it be MPEG TS or something else it would seem that for a client to be able to join mid stream there would need to be more IDR frames, but I admit there may be things I do not understand!
oviano
commented
4 years ago Hi @oviano ,
I have tried some parameters but there is still only one IDR frame.
SvtHevcEncApp -i cars1.yuv -w 1280 -h 720 -n 200 intra-period 20 -irefresh-type -1 -b test1.h265
@tianjunwork could you provide more information? Thanks.
Ok, I figured it out from looking at the code (EbPacketizationProcess.c).
The key is the intraRefreshType. I'm using VBR mode, and in this case the intraRefreshType needs to be set to a positive number that is the number of intraRefreshPeriods. So let's say you have an intraRefreshPeriod of 46 frames, then an intraRefreshType of 1 would mean write the headers again every 46 frames, a value for intraRefreshType of 2 would mean every 46 x 2 frames, etc.
I found the following command produces multiple IDR, with headers every 5s or so:
SvtHevcEncApp -w 1920 -h 1080 -bit-depth 8 -i capture.yuv -rc 1 -tbr 3200000 -fps-num 50 -fps-denom 1 -irefresh-type 5 -intra-period 46 -b encode.265
I haven't tried this with ffmpeg and mpeg-ts yet, but I'm hopeful it will work.
oviano
commented
4 years ago So just confirming that I have this working now in FFmpeg with a split file.
@mikaelsson I think the all that is needed is to add -forced-idr 0 to your FFmpeg command line and then it shouldn't matter which order you run your commands.
mikaelsson
commented
4 years ago Hello @oviano, thank you so much. that actually works. VLC has trouble playing the dumped file as it plays only one frame, but windows media player does the job.
I have tried -forced-idr in the past but I guess I was misinterpreting the meaning.
Since in the help topic it's range is listed from -1 to INT_MAX I thought it was the number of frames. I was setting it to 60 or 25. Turns out it is some kind of a multiplier. If I set it to 10, for example, it needs a little time before ffprobe starts detecting correct info. Setting it to a low value like 0 or 1 makes ffprobe detect everything right away.
I need to run some tests and if all goes well I'll close this issue in a couple of days.
oviano
commented
4 years ago My view coming at this fresh was that it was not clear at all from the documentation what the intra refresh type means. I had to look at the source code to figure it out.
My suggestion to the developers would be to consider splitting this parameter into two:
intraRefreshPeriod - as now
intraRefreshType - 0 CRA or 1 IDR. So as now but just two simple options. Default 0.
intraRefreshHeaders - 0 to INT MAX. IDR refresh type only. Number of intra refresh periods that should occur before resending headers (VPS, PPS, SPS). Default 0 (meaning don’t resend headers). (Note: Values above 1 only valid for VBR rate control method)
I think it’s combining these last two into one parameter that makes it hard to understand
Then the FFmpeg plugin should follow the same pattern with parameters names consistent with the SvtEncApp command
-irefresh-type -irefresh-headers
instead of the single:
-forced-idr
At the very least the documentation could be a little clearer even if you don’t split the parameter.
tianjunwork
commented
4 years ago @oviano Thank you for the feedback on intraRefreshType. I agree it needs more time/test to understand what does >0 mean. Since some customers are already using it, better to keep compatible on interface. I will add a detailed explanation in the user guide appendix about usage of intraRefreshType.

4 years ago Hello, Sorry, it took me some time to get around to this.
solution: I am using -rc 1 and -forced-idr 1. Resulted stream dumps are playable in most players. I think only the first idr is complete, all the following lack some kinid of information which results the problems on some players. but that is out of the scope of this issue.
Big thanks to everyone @tianjunwork , @guojiansheng0925 , @oviano .
I am trying to check live-streaming possibilities of the plugin. The problem is that there's no video in the output. For now I am trying to use the most basic settings leaving everything else on default. Using the latest versions of ffmpeg and plugin:
here is ffmpeg string:
in output it correctly identifies the stream and designates the needed outputs for transcoding. output:
however in stats bitrate never goes near the expected 10Mbps, varying from 200kbps to 500kbps approximately:
then I dump output into the file using multicat and check it with mediainfo:
there is no resolution in video part. playing it using vlc only plays audio.
