  • How to stop ffmpeg m3u8 download if not getting any stream update ?

    6 juillet 2022, par TheNoFace

    I'm making a bash script to download m3u8 stream on particular time using crontab.

    



    Sometimes server-sent stream url is invalid or stream stops because server fails to stream.
In both cases, playlist.m3u8 and chunk.m3u8 are both downloadable but stream file pieces in chunk.m3u8 don't update any longer. But ffmpeg keeps downloading "nothing" since chunk.m3u8 file contains any new streams.

    



    Input command :

    



    ffmpeg -i 'https://link.to/playlist.m3u8' -c copy -o '~/filename.ts'


    



    On abnormal cases :

    



    [generic] playlist: Requesting header
[generic] playlist: Downloading m3u8 information
[download] Destination: ~/filename.ts

    So, how can I make ffmpeg to stop when there's update no more on chunk.m3u8 file after some tries ?

    


  • FFMPEG, H264 Encoding : If frame size exceeds level limit, does it lead to video encoding failed ?

    I tried to figure out the reason for fail. I'm guessing from error message from the line frame MB size (68x120) > level limit (1620), frame size exceeds h264 level limits may be the issue.

    


    Is it the issue ? if it is, what's the solution for this ? if it's not, what went wrong ?

    


    Can somebody help please ? Thank you !
