using mediamtx to stream video to browser [closed]
18 octobre 2024, par MaximilianI am using rtsp to feed a video stream to mediamtx.


I want to display the feed in a browser but always get some errors.


I use the following to start mediamtx


podman run --rm -it -e MTX_PROTOCOLS=tcp -e MTX_WEBRTCADDITIONALHOSTS=192.168.x.x -p 8554:8554 -p 1935:1935 -p 8888:8888 -p 8889:8889 -p 8890:8890/udp -p 8189:8189/udp docker.io/bluenviron/mediamtx



I use this ffmpeg line to feed mediamtx :


ffmpeg -i "rtsp://127.0.0.1:10000/test" -f rtsp rtsp://127.0.0.1:8554/feed



I can view the feed with


ffplay rtsp://localhost:8554/feed



ffplay says some things about my stream


the mediamtx stream


Input #0, rtsp, from 'rtsp://localhost:8554/feed':
 Metadata:
 title : Session streamed with GStreamer
 Duration: N/A, start: 0.000000, bitrate: N/A
 Stream #0:0: Video: mpeg4 (Simple Profile), yuv420p, 320x240 [SAR 1:1 DAR 4:3], 30 tbr, 90k tbn, 30 tbc



the source stream


Input #0, rtsp, from 'rtsp://localhost:10000/test':
 Metadata:

 comment : rtsp-server

I use this html code try to display the video :



 




mediamtx gives the following output when the browser tries to connect :


2024/10/18 07:52:51 INF [RTSP] [session 7fe6a91a] created by 10.0.2.100:57542
2024/10/18 07:52:51 INF [RTSP] [session 7fe6a91a] is publishing to path 'feed', 1 track (MPEG-4 Video)

2024/10/18 07:52:52 INF [WebRTC] [session 9d4fb884] closed: the stream doesn't contain any supported codec, which are currently AV1, VP9, VP8, H264, Opus, G722, G711, LPCM



The stream is clearly h264... why is it complaining ?

Nginx RTMP "Server Error : No Such Stream"
7 août 2024, par Tony RuthI am trying to capture and stream video within my network 10.100.64.1/24 using libnginx-mod-rtmp. I followed a tutorial. I used the same URL for publishing and playing : rtmp ://10.100.64.4/lab/test But the player does not find the stream.


My nginx settings :


rtmp {

 server {

 listen 1935;
 chunk_size 4096;
 allow publish 127.0.0.1;
 allow publish 10.100.64.4/24;
 deny publish all;
 allow play 127.0.0.1;
 allow play 10.100.64.4/24;
 deny play all;

 application lab {

 live on;
 idle_streams off;
 record all;
 record_path /media/HLEV/GoPro/Raw;
 record_unique on;
 } 
 }
} 



The server lives on 10.100.64.4, so I published a video using ffmpeg :


ffmpeg -stream_loop -1 -re -i MyVideo.flv -c:v copy -c:a aac -ar 44100 -ac 1 -f flv -flvflags no_duration_filesize rtmp://10.100.64.4/lab/test



The publishing looks good. Last line of the above command :


frame=54030 fps= 60 q=-1.0 size= 119584kB time=00:15:01.00 bitrate=1087.3kbits/s speed= 1x 



And I can see that the video is being saved locally from the record block of the nginx settings.


Then I try to play the stream using ffplay :


ffplay -i rtmp://10.100.64.4/lab/test

ffplay does not find the stream.


I can observe both the publish and play commands by examine the access log of nginx :


sudo tail -2 /var/log/nginx/access.log 
10.100.64.4 [07/Aug/2024:12:24:56 -0500] PUBLISH "lab" "test" "" - 45365243 529 "" "FMLE/3.0 (compatible; Lavf59.27" (5m 36s)

I have tried using different video streams (directly from a webcam instead of from ffmpeg). I have also tried using different players (VLC instead of ffplay).


How do I connect to the stream ?
Do you need different URLs for publishing versus playing ? The way I understood it, publishing is on port 1395 and playing is on port 80, so there is no conflict with using the same URL.
Is there a way to list the currently active streams on my server ?
