Required information

Camera board id: ISVP, T31X
OpenIPC version: 2.4.08.24-lite
installation method: Majestic version which came with OpenIPC

Issue description

Like libnginx-mod-rtmp, which I reported earlier, these media servers (MediaMTX, OvenMediaEngine and SRS) don't work with Majestic as a video source over RTMP protocol. While, for example, they perfectly work with FFmpeg.

Expectations

I expected that Majestic is compatible with majority of media server programs.

Steps to reproduce

With MediaMTX: 1) Download it from its release page, unpack and run. 2) Push a stream from OpenIPC / Majestic / Settings / Output to rtmp://[MediaMTX]/mystream. 3) Open http://[MediaMTX]:8889/mystream with your browser. 4) The video in the browser does not play. 5) Close streaming from OpenIPC / Majestic / Settings / Output. 6) Stream a movie with FFmpeg, like this:

ffmpeg -re -i ./video.avi -c:v libx264 -c:a aac -bf 0 -f flv rtmp:/[MediaMTX]/mystream

7) The video in the browser , which you opened earlier, starts playing.

With the same settings, RTMP stream from OpenIPC / Majestic perfectly works with YouTube.

Majestic: master+91ad576, 2024-09-17

nginx-mod-rtmp: SUCCESS, but with some problems, which don't affect the video playback:
- Its statistics don't not show video size and FPS
- The stream at least one time disappeared from the statistics. However, the video continued to play.
go2rtc: FAIL go2rtc.log
MediaMTX: SUCCESS
OvenMediaEngine: FAIL ovenmediaengine.log
SRS: FAIL srs.log

skilurius commented 2 months ago

nginx-mod-rtmp requires some additional metadata for resolution and fps, generally this information could be extracted from nal units (ffprobe/ffmpeg does this).
SRS Can you please elaborate the exact problem, the log shows no issues.
go2rtc Can you provide an example for a reference test with ffmpeg?

MalgathThelamin commented 2 months ago

nginx-mod-rtmp I'm sorry, I don't understand. You mean, that Majestic doesn't send this metadata, it is by design and you are not planning to implement it?
SRS If I push the video from Majescic to rtmp://192.168.0.2/myapp/mystream, it does not play at http://192.168.0.2:8080/myapp/mystream.m3u8. If I stop Majestic and push a video with ffmpeg to the 1st URL, video plays at the 2nd URL. Isn't Drop ts segment, sequence_no=0, uri=mystream-0.ts, duration=2147456875ms in the log file an error?
go2rtc does not work even with ffmpeg. I raised an issue in go2rtc repository. Please don't pay any more attention to this program.

MalgathThelamin commented 2 months ago

SRS

When video does not play, it looks like this in the log file:

[2024-09-18 17:52:04.004][INFO][4671][4v5653rw] HTTP #0 192.168.1.205:55576 GET http://192.168.0.2:8080/myapp/mystream.m3u8, content-length=-1

The ./objs/nginx/html/myapp/ folder contains only one file: mystream-0.ts.tmp.

When I push the video with ffmpeg, mystream.m3u8 file appears in the folder first, then mystream-#.ts files start to appear.

skilurius commented 2 months ago

I tested the following scenario:

docker run --rm -it -p 1935:1935 -p 8080:8080 ossrs/srs:6 objs/srs -c conf/docker.conf
docker run --rm -it -p 1935:1935 airensoft/ovenmediaengine:latest

cli -s .outgoing.server rtmp://192.168.1.85/app/live
ffprobe rtmp://192.168.1.85/app/live

SRS seems to work fine, but OvenMediaEngine requires more debugging.

I'm sorry, I don't understand. You mean, that Majestic doesn't send this metadata, it is by design and you are not planning to implement it?

This might follow at a later time, currently the most important part is to have overall compatibility with the listed applications.

Isn't Drop ts segment, sequence_no=0, uri=mystream-0.ts, duration=2147456875ms in the log file an error?

Indeed, this should be addressed on the next build

MalgathThelamin commented 2 months ago

Sorry, I am not familiar with Docker. I have compiled the latest version of SRS now from source according to the manual.

git clone -b develop https://github.com/ossrs/srs.git
cd srs/trunk
./configure
make
./objs/srs -c conf/srs.conf

Can you test this scenario, please?

srs.log

ffprobe shows the following output:

You need to update ffmpeg (to support H265) or use H264 instead.

Do you have a reference for OvenMediaEngine? I tested the following, which is working on SRS:

wget http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4
ffmpeg -re -i BigBuckBunny.mp4 -c copy -f flv rtmp://192.168.1.85/app/live
ffprobe rtmp://192.168.1.85/app/live

Oh, my mistake. I completely forgot, that 2 days ago I noticed, that YouTube started accepting H265 stream from T31X (wasn't accepting a month ago), and forgot to switch back.

After switching Majestic back to H264:

ffprobe shows correct stream information
The stream shows up in SRS console (http://192.168.0.2:8080/console/en_index.html > Streams)
The stream plays normally at http://192.168.0.2:8080/myapp/mystream.flv
HLS files are not being created in ./objs/nginx/html/myapp/ normally, and, therefore, the stream does not play at http://192.168.0.2:8080/myapp/mystream.m3u8.

srs.log

If I push a video with ffmpeg, HLS files are being created normally.

Do you have a reference for OvenMediaEngine?

Rephrase your question, please.

MalgathThelamin commented 2 months ago

I also noticed, that from time to time, the stream disappears

from SRS console, while http://192.168.0.2:8080/myapp/mystream.flv continues playing
from nginx-mod-rtmp console, while http://192.168.0.2:8080/myapp/mystream.m3u8 continues playing

MalgathThelamin commented 2 months ago

I also noticed, that Majestic on ssc378de streams perfectly to all applications, including SRS (HLS at http://192.168.0.2:8080/myapp/mystream.m3u8) and OvenMediaEngine.

skilurius commented 2 months ago

Rephrase your question, please.

I mean if you have a working reference test to verify the initial function, for example:

docker run --rm -it -p 1935:1935 airensoft/ovenmediaengine:latest
wget http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4
ffmpeg -re -i BigBuckBunny.mp4 -c copy -f flv rtmp://192.168.1.85/app/live
ffprobe rtmp://192.168.1.85/app/live

I also noticed, that Majestic on ssc378de streams perfectly to all applications, including SRS

Interesting, that could indicate a problem or incompatibility on the (ingenic) sdk. I will try to verify this later.

MalgathThelamin commented 2 months ago

I test OvenMediaEngine like this. My installation method is partially based on its documentation, but uses the latest source and does not install the program.

git clone https://github.com/AirenSoft/OvenMediaEngine
cd OvenMediaEngine/src
../misc/prerequisites.sh
make release
cd bin/RELEASE
mkdir conf
cp ../../../misc/conf_examples/Server.xml conf
./OvenMediaEngine

Publishing a video file:

wget http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4
ffmpeg -re -i BigBuckBunny.mp4 -c copy -f flv rtmp://192.168.0.2/app/live
ffprobe http://192.168.0.2:3333/app/live/llhls.m3u8

The output shows a correct stream information. The video is playable at http://192.168.0.2:3333/app/live/llhls.m3u8.

Publishing a H264/AAC stream from ssc378de to rtmp://192.168.0.2/app/live. The ffprobe output is correct. The video is playable.

Publishing a H264/AAC stream from t31x to rtmp://192.168.0.2/app/live. ffprobe does not finish. The last line it outputs is:
