    I have this command :

    


    ffmpeg -i video.format -movflags use_metadata_tags -map metadata 0 -vcodec libx265 -acodec copy output.mp4


    


    I get this error :

    I have got a mpeg ts file with following composition (shown by ffprobe)

    I intend to transcode this so that I copy the video as it is but the audio will be encoded to aac ...so that I can play it in the browser.

    


    I use the following ffmpeg command to attempt that

    


    ffmpeg -i ff_vlc.ts -vcodec copy -acodec aac -map 0:v:0 -map 0:a:0 ff_vlc_2.ts


    


    this throws errors with -16976906 as follows..........( I have clipped the repetitive excessively long output)

    I tried the above even with this command

    


    ffmpeg -analyzeduration 2147483647 -probesize 2147483647 -i ff_vlc.ts -vcodec copy -acodec aac -map 0:v:0 -map 0:a:0 ff_vlc_2.ts


    


    Still get the same errors. Only changed lines in the output are

    


    [mpegts @ 0x55e1b757d580] Failed to allocate buffers for seekback
[mpegts @ 0x55e1b757d580] Could not find codec parameters for stream 1 (Audio: ac3 ([129][0][0][0] / 0x0081), stereo, fltp): unspecified sample rate
Consider increasing the value for the 'analyzeduration' (2147483647) and 'probesize' (2147483647) options


    


    


    VLC player has no problems in playing this audio ... only ffmpeg cannot decode.

    


    How do I fix this ?

    


    Please help
Thanks

    


  • Can MPMoviePlayerController play m3u8 file

    26 novembre 2013, par Nitesh

    I am trying to play a m3u8 file using MPMovieplayercontroller
    i pass the url to the MPMovieplayercontroller
    But it will not play. Is it possible ?

    I am converting flv,avi video file formats into m3u8 files using ffmpeg for live http streaming on my server.

    The m3u8 url works when i pass it to VLC as a network stream on my mac.
    I know this has been asked a number of times but i have not got any satisfactory answers.

    Regards
    Nitesh
