Config - "Test" against Raspberry Pi Zero 2 W rtsp server (cVLC) fails: "Protocol not supported"

I have a Raspbery Pi Zero 2W running Bullseye (courtesy of the generous folks at Q-Engineering: ready-to-burn 64-bit image for Zero) where I am running the suggested RTSP server described in the documentation at https://www.raspberrypi.com/documentation/accessories/camera.html#rtsp. Looks like the libcamera project pipes its output to "cvlc" which I understand is a command-line invocation of VLC without a window/gui. So it looks like VLC is acting as the rtsp server being fed by libcamera-vid.

The camera is the official Raspberry Pi HQ 12 Megapixel (see specs below) with the standard lens.

My server command is:

pi@raspberrypi:~ $ cat stream.sh
#!/bin/bash
#
# added: 192.168.1.12 where nothing existed
#
libcamera-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://192.168.1.12:8554/stream1}' :demux=h264
pi@raspberrypi:~ $

I am able to connect to this server using VLC on Windows; I have had 6 sessions running with barely noticeable difference, if any, on the Pi Zero where the CPU usage hovers around 55-63%. Here is URL I used for VLC on Windows: vlc_2022-01-28_20-40-34

Imbued with success, my next step is to have an instance of moonfire-nvr try to connect and then I am going to see what quality of connection is maintained over time.

(Note: I compiled gstreamer (1.19.2) and its rtsp, but have been having problems with gstreamer and PiZero's libcamera, so i backed off and tried the official Raspberry Pi document, supra, which has a section for creating an RTSP server.)

I configured a camera to the PiZero2 and when I tried to test, I received this error message: "Protocol not supported" 2022-01-28_20-41-49

Now, Raspberry's libcamera-vid RTSP server does not have a user/password configuration in the proposed command line. When I connected with VLC, no user or password was required. So in Moonfire-nvr, I left the username and password variable empty and tried. When I encountered the "Protocol not supported", I then put in some bogus values, jlpoole/bogus, to see if a different error message was triggered. Nothing change, same error message.

The libcamera-vid code is at https://github.com/raspberrypi/libcamera-apps/blob/main/apps/libcamera_vid.cpp. But, I suspect the problem really lies within VLC's implementation of an rtsp server.

To Reproduce Steps to reproduce the behavior:

On a RPiZero2 run: libcamera-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://192.168.1.12:8554/stream1}' :demux=h264
Launch moonfire-nvr config
Go to configuration of camera and enter information, click Test
See error "Protocol not supported"

Expected behavior Standard confirmation that the connection worked.

That button is still using ffmpeg rather than retina. You could try running Retina's cargo run --example client mp4 and/or an actual moonfire-nvr run and see if the result is any different.

Created a fresh database and populated with the PiZero2 camera.
Here's a log of the run... Retina looks to have had problems, too. moonfire_rustbacktrace_log.zip

From those logs:

E20220128 22:17:35.159 tokio-runtime-worker moonfire_nvr] panic at '/home/jlpoole/.cargo/registry/src/github.com-1ecc6299db9ec823/retina-0.3.4/src/codec/h264.rs:593:57': called `Option::unwrap()` on a `None` value

That looks like a bug that @unrelentingtech just fixed in Retina. I haven't updated Moonfire NVR to use the new version yet.

I executed "svn up" around 10:00 a.m. PST 1/29/22 and then "cargo build" from within /usr/local/src/moonfire-nvr.git/trunk/server . It looks like I picked up your change 6ca9f45 as evidence by line 51 of Cargo.toml.

That log message says retina-0.3.4. It hasn't picked up the commit in question. I think github's Subversion mirrors are not reliably up-to-date.

I'll clone anew and update when I have it running.

Actually, on second look: the log says retina-0.3.4 but the compile output above says retina-0.3.7. You ran cargo build which would have produced an unoptimized build in target/debug/moonfire-nvr, and the log was from target/release/moonfire-nvr. Is it possible you ran an old release build rather than also doing cargo build --release first?

I just did "cargo build". Have now launched "cargo build --release" from within server directory and its building everything anew. Good catch.

After rebuild, reran. I full log captured by "script", but for simplicity, here is the type of error message:

I think Unsupported Transport means that Moonfire NVR requested TCP and the server only supports UDP (or vice versa). You could try flipping this option in the config.

Protocol not supported might be ffmpeg's way of saying the same thing.

I do not know what you are referencing in "the config.". Moonfire's config?? If so, I ran in config mode and did not see anything in the cameras setup that specifies TCP vs. UDP. Or do you mean the cvlc command line serving up the stream? I tried adding "--sout-rtp-proto tcp " as follows:

 libcamera-vid -t 0 --inline -n --info-text "PiZero2 `date`" -o - | cvlc stream:///dev/stdin  --sout '#rtp{sdp=rtsp://192.168.1.12:8554/stream1}' --sout-rtp-proto tcp :demux=h264

But no luck.

I also replaced "tcp" with "upd" and tried, still the same error.

Moreover, included in the current code for VLC is https://code.videolan.org/videolan/vlc/-/blob/master/modules/access/live555.cpp

I'm guessing that VLC uses, perhaps exclusively, LIVE555 for its rtsp server. That may not have any bearing on what you are considering, but I thought I'd bring it to your attention as you had taken a dive into LIVE555's code to form an opinion. Perhaps the inconsistent handshake between the cVLC piped content from Pi Zero and to Moonfire may be a caused by something you might remember. A shot in the dark.

Also, this venture into using the libcamera pipe into cVLC was becuase I was having problems with gstreamer and when I saw this was a supported activity, I thought I'd try it to confirm it can be done. Also, my foray into Gentoo is on hold because the initial boot-up files for Raspberry Pi products are proprietary -- i was hoping U-Boot could replace, and I'm seeing a Gentoo on Raspberry Pi kind of struggling, so I didn't want to take on a 10 hour investigation if I could finesse getting an rtsp server sending to Moonfire from a Raspberry Pi Zero 2 board on line asap to evaluate drop-outs and other anomalies I have experienced with Reolink cameras. So now high priority on this issue, I'll probably go back to trying to get gStreamer on Bullseys working, even if with an old USB Logitech camera just so I can start sending packets to moonfire-nvr. (I have discovered on the Pi Zero that having a display preview while streaming causes problems and that one is best advised to run an rstp server with the --no-preview ('-n') option.)

I do not know what you are referencing in "the config.". Moonfire's config??

Yes, the rtsp_transport option:

(default) means as specified on the commandline (--rtsp-transport command line option which in turns defaults to tcp). I added a config option recently so you can specify a different transport for different cameras.

Thanks... that line seemed invisible to me. I tried all three states: 1) default, 2) tcp, and 3) udp. I ran moonfire-nvr for 4 sets of error messages each and then terminated concluding the rtsp_transport variable did not make a difference. (I reset the camera to default lest I forget in the future.)

I tried this myself.

With TCP, I got the same behavior you described.

With UDP, I saw a different error: Ok response to SETUP CSeq=2: Transport header is missing server_port parameter. Moonfire/Retina is sending this:

Transport: RTP/AVP/UDP;client_port=22660-22661

then VLC is sending this:

Transport: RTP/AVP/UDP;destination=127.0.0.1;port=1234-1235;ttl=1;mode=play

The RFC says that port (rather than server_port) is for multicast. Apparently we were supposed to specifically request unicast if we wanted it:

   unicast | multicast:
          mutually exclusive indication of whether unicast or multicast
          delivery will be attempted. Default value is multicast.
          Clients that are capable of handling both unicast and
          multicast transmission MUST indicate such capability by
          including two full transport-specs with separate parameters
          for each.

...and we do want it. Retina doesn't support multicast. I accidentally left the unicast out of the transport spec for UDP. (It was there for TCP.) That might affect other servers, and it's easy to fix.

After that, there's some other error, but I might as well fix this one anyway...

A bug in libcamera was resolved ( [BUG] libcamera-vid piped into cVLC runs then crashes #238 ), so I'm back to streaming using clvc piped in from libcamera-vid.

I started with a fresh pull of Retina and still error out. I wasn't sure if the commit 1a00b5e was to fix the problem.

VLC doesn't seem to support serving with --rtsp-transport=tcp; that will never work.

1a00b5e made Retina get slightly further with VLC for me when using --rtsp-transport=udp. I found it really frustrating to work with from the CLI, as it seems to lack such basic functionality as a CLI option for setting a logfile. I got it to work well enough to figure that out on my laptop (where I'd set a logfile through the UI already) then it hit some other problem and I gave up for the time being. Ultimately VLC is a dead end as an RTSP server anyway.

Given the word from Raspberry Pi gurus that they are moving away from cVLC as an rtsp server, I see no point to tracking support for cVLC and therefore closing this issue. Not a good use of time.
