  • FFMPEG Video Capture fails

    20 août 2018, par Ankur Tripathi

    I am trying to capture video using FFmpeg and Directshow(https://github.com/rdp/screen-capture-recorder-to-video-windows-free) filter but it works sometimes and fails some time

  • Converting DTS to AAC with ffmpeg shifts spoken audio to the right

    18 août 2018, par Giuseppe

    I am using ffmpeg to convert mkv movies to mp4, like so :

    $ ffmpeg -i source.mkv -c:v copy -c:a aac destination.mp4

    By doing this, the audio stream gets converted from the original DTS :

    Stream #0:1: Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s (default)

    To AAC :

    Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 394 kb/s (default)

    The resulting file plays just fine, except that the spoken audio (what I am assuming would be sent to the central channel in a 5.1 configuration) sounds clearly shifted to the right, when listening through the MacBook’s built-in speakers or my stereo headphones. Note that music and other sound effects appear unaffected, properly balanced. Also note that I have been able to reproduce this behavior with a variety of source files.

  • Can't play MP4 after download

    14 août 2018, par joe

    I am using a downloader program in Firefox to download videos playing in Firefox. Most of the time final MP4 is playable. But sometimes I get MP4 file that looks good(shows file size) but shows no length of video in file explorer.

    I get this error log.

    Could not get information from media 'ESPN 2 (HD) Live Stream Channel' from file 'C:\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4'. The file might be corrupted.

    [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000024c3900] moov atom not found

    C :\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4 : Invalid data found when processing input

    It looks like moov atom is missing thus can’t aggregate PART file into final playable MP4.

    I understand that during download, PART file is created. Then later PART is aggregated into final MP4.

    So question is how can I make this MP4 to play ?
    or is it impossible to play cus moov atom was not properly downloaded ?

    Any thoughts ?
    Thanks
