(Development under Windows, libVLC 3.0.7.1, it's about playing video and audio stream via a playlist URL)

I recently switched from libvlc 2.x to 3.x and noticed that it directly supports playlist URLs now. Which is nice.

E.g. i can call libvlc_media_new_location() with a URL to a playlist and it will play the stream.

But i noticed this only worls with video streams, not with pure audio streams.
Examples:
Video stream URL: http://mcdn.daserste.de/daserste/de/master.m3u8

Content:

Code: Select all

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=4237552,AVERAGE-BANDWIDTH=4118400,CODECS="avc1.640020,mp4a.40.2",RESOLUTION=1280x720,FRAME-RATE=50.000
master_3744.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=2314400,AVERAGE-BANDWIDTH=2156000,CODECS="avc1.4d401f,mp4a.40.2",RESOLUTION=960x540,FRAME-RATE=50.000

master_608.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=366168,AVERAGE-BANDWIDTH=352000,CODECS="avc1.66.30,mp4a.40.2",RESOLUTION=480x270,FRAME-RATE=50.000
master_320.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=219384,AVERAGE-BANDWIDTH=202400,CODECS="avc1.42c015,mp4a.40.5",RESOLUTION=320x180,FRAME-RATE=50.000
master_184.m3u8

This works fine.

Audio stream URL: http://www.wdr.de/wdrlive/media/einslive.m3u
Content:

Code: Select all

http://wdr-1live-live.icecast.wdr.de/wdr/1live/live/mp3/128/stream.mp3?ar-distributor=ffa1

This does not work.

The VLC player however plays both URLs fine.

Is there anything i can do about this? (Naturally i have no control over the content of the playlists)

In C# you would do like this

Code: Select all

static async Task Main(string[] args)
{
    Core.Initialize();

    using var libVLC = new LibVLC();
    using var media = new Media(libVLC, "http://www.wdr.de/wdrlive/media/einslive.m3u", FromType.FromLocation);
    await media.Parse(MediaParseOptions.ParseNetwork);
    using var mp = new MediaPlayer(media.SubItems.First());
    mp.Play();
    Console.ReadKey();
}

It seems the corresponding function in libvlc is libvlc_media_parse_with_options(). I'll investigate.

Thanks for the reply.
