    We don’t know them, we didn’t try them, but you can take a peek.

  • Chromecast HLS : Unable to derive timescale

    31 juillet 2020, par Scott

    I'm trying to get fmp4 HLS playing back on a new Chromecast (3rd gen I believe, not Ultra).

    


    I've tried encoding the content with ffmpeg using both x264 and h264 libraries.
The main profile initially gives me a codec not supported error, remove the codec list from the hls manifest fixes this issue.

    


    Switching to baseline (which is not ideal) doesn't give the codec error.

    


    Both then (after removing the codec definitions or using baseline) give the following error :

  • ffmpeg filter_complex multiple overlays - why are they not syncing properly

    28 décembre 2023, par howdood

    I'm setting up live streaming using three overlaid inputs in ffmpeg. O:v is a webcam directly connected to the streaming box (a headless linux box) while 2:v and 3:v are ultra-low latency UDP streams from two remote R-Pis.

    


    The filter_complex argument I'm using (that works, with all three video inputs perfectly in sync) is
[0:v] fifo [v1] ;[2:v] fifo [v2] ; [3:v] fifo [v3] ;[v1]setpts=PTS-STARTPTS[sync1] ;[v2]setpts=PTS-STARTPTS[sync2] ; [v3]setpts=PTS-STARTPTS+5/TB [sync3] ;[sync1][sync2] overlay=x=W-w:y=H-h [out1] ;[out1][sync3] overlay=x=0:y=H-h [vfinal]

    


    Two questions about this :

    


      


    1. Why am I having to add +5/TB to [sync3] via setpts (in bold above) ? If I omit that, [3:v] is synced in to the stream noticeably ahead of the other two inputs. My best guess is that this may be to compensate for the processing time of the first overlay [sync1][sync2] which is introducing extra latency into that part of the stream. Is that right ?

      


      2. 


    2. Importantly - the value of the extra pts compensation has to be dialed in by hand and will be specific to the underlying hardware used. Is there a way of getting ffmpeg to calculate this automatically so I don't have to worry about keeping in dialed in, in production ?

      


      3. 


    


    Thanks for reading ! I'm at the limit of the ffmpeg docs here...

    


  • youtube to mp3 conversion on server

    3 juin 2016, par user1610362

    I’m wondering how can this site process file so quickly youtube-mp3.org. Could i use xuggler and convert to mp3 without downloading flv ? Could i use youtube-mp3.org in my program in order to download mp3 file from some youtube link. I’m trying to make server in java that has these capabilities and i could accomplish that just by downloading file and converting to mp3 but that isn’t fast enough...
