  • Using ffmpeg to generate dash manifest and it cannot be played by dash.js

    18 mars 2019, par Punkhead

    I’m using ffmpeg to encode incoming stream via rtmp protocol, the code as following :

    ffmpeg -re -i rtmp://localhost:1935${StreamPath} -use_timeline 1 /
    
-use_template 1 -window_size 10 -min_seg_duration 5000 -f dash out.mpd

    The manifest looks like this :

    then it fails to playback...

    Is it because I didn’t set the parameters right on ffmpeg or this is a bug in dash.js ?

    I really stuck here !

  • Use ffmpeg for incoming youtube HLS live stream and output to rtmp

    14 avril 2018, par hrs

    I can’t get ffmpeg to work with live streams from youtube. Normal non-live videos work just fine. But with live streams ffmpeg seems like it doesn’t make enough requests for new segments. It basically downloads, say a 3 second segment, then nothing happens for 10 seconds or so, then it downloads a new segment, repeat...

    ffmpeg -i '$(./youtube-dl -f best -g https://www.youtube.com/watch?v=emGI3UrzIMc)' -f flv rtmp://192.168.0.11/myapp/mystream

    So what’s the automagic command ?

    Following is the output of the command above. The <my note="note"></my> is added by me for description purposes.

    At start execution goes smoothly. It then freezes for 10 or 15 sec at <my note="note" 1="1"></my>. It then downloads the part of the stream - <my note="note" 2="2"></my>, plays is, then freezes again for some seconds. Then downloads the next part - <my note="note" 3="3"></my>, plays it, freezes, and so on...
