• How can I publish an RTSP stream to a MediaMTX instance with TLS encryption configured ? [closed]

  15 février 2024, par cmd

  I have an instance of (MediaMTX) running on my laptop. I have an Amcrest IP camera. I can publish the camera's RTSP stream to the server so that the stream can be accessed from the MediaMTX instance.

  


  However, I want to encrypt the stream. On the Github page for MediaMTX, they detail how TLS encryption can be enabled for incoming and outgoing RTSP streams by generating a server.key and server.crt and editing lines in the .yml configuration file. Streams can then be published and read with RTSPS and port 8322.

  


  I have followed these steps, and set up the following path for my IP camera in the .yml :

  


  ###############################################
# Path settings

# Settings in "paths" are applied to specific paths, and the map key
# is the name of the path.
# Any setting in "pathDefaults" can be overridden here.
# It's possible to use regular expressions by using a tilde as prefix,
# for example "~^(test1|test2)$" will match both "test1" and "test2",
# for example "~^prefix" will match all paths that start with "prefix".
paths:

  cam1:
    source: rtsp://user:password@192.168.68.142:554
    runOnInit: ffmpeg -i rtsp://user:password@192.168.68.142:554 -c:v copy -c:a copy -f rtsp rtsps://localhost:8322/stream/cam1


  


  But I am getting the following output from my MediaMTX instance when it runs :

  


  2024/02/15 18:20:59 INF [path cam1] [RTSP source] ready: 2 tracks (H264, MPEG-4 Audio)

  I have no errors and was able to publish the stream with the same path configuration (using rtsp ://, not rtsps ://) when using no encryption. What possible solutions can I try ?

  


• VideoJS for HLS streaming not working on iOS

  13 février 2024, par Aames

  I have a website where I stream audio using HLS (m3u8 playlist + ts files).
I use VideoJS 8.3.0 to handle the stream in the frontend side.
The streaming works in all devices (PC, Android, Mac) except in iOS where it works intermittently and often it blocks.

  


  Here is my videojs initialization :

  


  player = videojs('stream-id', {
            controls: false, autoplay: true, preload: 'auto',
            html5: {
               vhs: {overrideNative: false},
               nativeAudioTracks: true
           }
        });

...

player.src({ type: 'application/x-mpegURL', src: 'https://.../master.m3u8' });



  


  And these are the headers of the m3u8 file :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-PROGRAM-DATE-TIME:2024-02-13T09:00:00Z
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXTINF:10.007800,
master0.ts
#EXTINF:7.214989,
master1.ts
....


  


  I use ffmpeg to create the playlist from mp3 files :

  


  ffmpeg -i inputFileName -c:a aac -b:a 128k -ac 2 -f hls -hls_time 10 -preset ultrafast -map 0:a -flags -global_header -hls_list_size 0 -hls_flags append_list outputFileName



  


  Am I doing something wrong ? Any help would be appreciated
Thanks

  


  I tried this solution : Videojs HLS m3u8 files are not playing in iOS devices and safari browser but it does not work for me

  I figured out the issue is color primaries prim:reserved, and the command can be updated to a working one by re-writing input primaries as following :

  


  ffmpeg -i input.mp4 -vf "colorspace=all=bt709:iprimaries=bt709" -frames:v 1 out.jpg


  


  However, I would like to compile ffmpeg.wasm so that it handles reserved primaries just like the one from homebrew.

  


  Any idea what the compiled ffmpeg.wasm is missing ?
