  • Using youtube-dl and ffmpeg (or vlc) to transcode a YouTube live stream to rtsp rtmp udp rtp

    11 septembre 2018, par Matthew Wachter

    I’m trying to use youtube-dl to transcode the YouTube NASA ISS live stream (or any YouTube stream) to rtmp or rtsp. I think I have the right command but for some reason I can’t get anything to connect to my newly transcoded stream.

    Here’s the command I’m using :

    youtube-dl -f best "https://youtu.be/RtU_mdL2vBM" -o - | ffmpeg -re -f mp4 -i pipe:0 -ar 44100 -f flv rtmp://localhost:1935/test/test'

    The command appears to work and I see information about the stream files opening from YouTube but when I use the command below, vlc reports that it is unable to connect to the stream.

    vlc rtmp://localhost:1935/test/test

    If I use this next command the stream plays correctly in vlc and I can see that the youtube-dl part is functioning.

    youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc -

    or simply just

    vlc -vvv https://youtu.be/RtU_mdL2vBM

    So it seems that ffmpeg is the issue or maybe I need a streaming server between the transcode and my desired destination (vlc or TouchDesigner). I’ve also tried using vlc in place of ffmpeg/youtube-dl :

    vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

    or

    youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc - --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

    and view with

    vlc rtsp://localhost:554/test

    Unfortunately I haven’t been able make either of those methods work. I can’t even see the stream in vlc if I try to duplicate it like this :

    vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#duplicate{dst=display,dst="#transcode{vcodec=h264,vb=800,acodec=none}:rtp{,sdp=rtsp://:554/test}"}'

    Any advice would be greatly appreciated. Thanks !

    EDIT
    Here’s the ffmpeg log as requested. The program continues to run without error so I interrupted it after a about a minute.

  • Best practice to play segments of larger video files in HTML5 video format

    8 octobre 2015, par zx98

    I have to migrate a legacy project from Windows Media to HTML5 video/audio. The system should provide video/audio content to the web user meeting following criteria :

    1. Playout : Segments (TcIn to TcOut) of large video/audio files should be played "on the fly" to the web user. (Cutting the source material into segments does not work because there is a high overlap rate between segments, so 3-4 times more HDD space and a lot of extra programming would be needed. Markered playout of the large source files is not an option either as there are forbidden parts of the source material which should never be available to the user).
    2. Cutting : In general, users are permitted to make copies of the material. Indeed, by using the dowload function, users can download selected segments. I guess, this is not a problem : a service starts a cutting software (probably ffmpeg) that cuts the video, and the user is notified by email to download the product. (That’s the way I do it now but there might be a more simple option).
    3. Formats : what is the preferred video/audio format that most browsers (Chrome, Firefox, Opera, Android) support ?
    4. Server : If possible, I would keep Windows Server because the database behind is MS SQL Server.

    (Windows Media Server and WMEncoder currently works fine for all the above, however WM is not suppored by browsers any more. That is the reason for reengineering).

    I would appreciate any of your suggestions on how to rebuild this video/audio system. (What software elements to use and how).

    Thank you.

    -------- addition -------
    Dear commenters,
    Thank you for your comments. Please note that the above is one single question, the rest is just a detailed description of the issue/conditions, as recommended by stackoverflow.com. I guess, the answer is also very simple, I try to write it myself :

    1. You should keep the large video/audio files in xxx format because...
    2. You create a playlist file like this example... for each of the the segments.
    3. You install the xxx streaming software component on the web/media server to playout the segments.
    4. You can address and play the segments from the client side web browser like this :...
    5. For asynchronous cutting, yes, I recommend ffmpeg, try these profile settings.

    Just a few parts in bold are missing. Thanks to anyone who can fill them.
