  • Extract audio from Transport Stream and preserve length

    15 décembre 2015, par yuiu

    I’m using ffmpeg to extract audio from MPEG Transport Stream file recorded by DVB-S card. The command :

    ffmpeg -i video.ts -vn audio.wav

    The source file seems to be corrupted. I noticed the corruption happens from time to time, especially for videos longer than 1 hour. I’ve got errors like these :

    [mp2 @ 0x1bb5500] Header missing
    Error while decoding stream #0:1
    [mpegts @ 0x17eaf40] Continuity check failed for pid 5261 expected 2 got 6

    The problem is that the resulting audio.wav is shorter than the source video (40m33s and 40m59s accordingly). I’m looking for the way to preserve the original length in the resulting audio file.

    I tried the recent ffmpeg under Windows and avconv under Ubuntu, output format was MP3 and WAV. For every case I’ve got the same results.

  • Cannot find a proper format for codec h264 (id:27), pixel format none ffmpeg [closed]

    15 août 2020, par David Pinto

    I'm currently trying to run a ffmpeg command to stream video to a rtmp server from my gopro that is connected to a capture card connected to my raspberry pi 4 2gb.

    


    Command :

    


    ffmpeg -ar 44100 -ac 2 -f alsa -f v4l2 -codec:v h264 -framerate 30 -video_size 1920x1080 -itsoffset 0.5 -i /dev/video0 -copyinkf -codec:v copy -codec:a aac -ab 128k -g 10 -f flv rtmp://x.x.x.x/live/test


    


    Error :

    


    


    [video4linux2,v4l2 @ 0xb32350] Cannot find a proper format for codec 'h264' (id 27), pixel format 'none' (id -1)
Assertion *codec_id != AV_CODEC_ID_NONE failed at src/libavdevice/v4l2.c:811

    


    


    I would like to try and find some help or alternatives to stream the video to a rtmp link.

    


  • Why is ffmpeg cut setting the wrong duration on my output file

    9 mai 2023, par danielson317

    Setup

    


    I am trying to break a video up into parts using some basic commands I have seen available.

    


    I have tried :

    


    ffmpeg -ss 00:00:00 -t 00:11:42 -i 'original.m4v' -acodec copy -vcodec copy 'output.m4v'

    


    I also tried more generic (and much slower) :

    


    ffmpeg -ss 00:00:00 -t 00:11:42 -i 'original.m4v' 'output.m4v'

    


    I am on Ubuntu 20 with ffmpeg 4.2.7-0. I know it is a little outdated but this computer lost it's network card so I cannot update it at this time.

    


    The problem

    


    In both cases the video cuts correctly to only have the first 11:42. However the video properties state the video is 31 minutes long (the length of the original). This file size also reflects the reduced size I would expect from the cut. When I play the video in VLC it reports the video is 31 minutes long but scanning or playing past 11:42 "crashes" the playback.

    


    Question

    


    Why is the new video reporting the wrong length and how do I correct this ? Preferably in the conversion process not a secondary command.
