  • How can I fix missing footage when I trim a video through ffmpeg ?

    18 juillet 2021, par LPMA

    I'm trying to remove commercials from an old PVR recording, and am extracting the main program by trimming/splitting the original file into separate parts :

    


    ffmpeg -i name.avi -ss 00:02:00 -to 00:08:20 -acodec copy -vcodec copy part01.avi
ffmpeg -i name.avi -ss 00:11:23 -to 00:22:03 -acodec copy -vcodec copy part02.avi
ffmpeg -i name.avi -ss 00:25:34 -to 00:36:37 -acodec copy -vcodec copy part03.avi
ffmpeg -i name.avi -ss 00:40:08 -to 00:52:11 -acodec copy -vcodec copy part04.avi
ffmpeg -i name.avi -ss 00:55:41 -to 01:52:53 -acodec copy -vcodec copy part05.avi


    


    For some reason, parts 3 and 5 are perfect, whereas parts 1, 2 and 4 each have about 9 seconds where the audio is playing against a "frozen" frame before the video part starts playing normally. The audio data seems to be intact (and cut at the designated place), but the video seems to be missing that data. I'm guessing it might have to do with reference frames ? Is there a quick way to fix/avoid the issue ? I would like to avoid data loss (through transcoding) as much as possible.

    


  • FFmpeg Converted files not working on firefox

    23 septembre 2014, par Kevinkuijer

    When i convert a file with ffmpeg and play the video in firefox i get this error :

    "VIDEOJS:" "ERROR:" "(CODE:3 MEDIA_ERR_DECODE)" "The video playback was aborted due to a     corruption problem or because the video used features your browser did not support." Object { code: 3, message: "The video playback was aborted due to a corruption problem or because the video used features your browser did not support." }

    In other browsers it’s working perfect.
    This is my ffmpeg convert command :

    ffmpeg -i {input} -b 5500k -minrate 5500k -maxrate 5500k -bufsize 5500k -ab 384k -vcodec libx264 -acodec aac -strict -2 -ac 2 -ar 96000 -s 1280x720 -y {output}

    Can someone tell me why the videos won’t play in firefox ?

  • ffmpeg does not produce smooth videos from mkv h265 [migrated]

    13 décembre 2018, par user3776738

    It’s kind of subjective, but I’m not able to produce 100% smooth videos with ffmpeg.
    As input I use https://www.libde265.org/hevc-bitstreams/tos-1720x720-cfg01.mkv as a example.This is a h264 mkv video which is running really badly with my vlc player on my win7 laptop.Converting it to a h264 video let it play much better, but it still appears not to be 100% smooth. Especialy in Vegas 9 it even hangs like once a second.

    Other h264 videos even with 1080p or bigger run perfect with vlc and much better with Vegas, so it is not my laptop.

    its seems that there can be a lot of differences between h264 and h264 ??
    what could i try to make them more smooth ?

    I’m using following command to convert the video :

    ffmpeg.exe -i INPUT_FILE -ac 2 -vf scale=trunc\\(oh*a/2\\)*2:480 -c:v libx264 -sn -dn -map_metadata -1 -map_chapters -1 -profile:v high -level:v 4.0 -pix_fmt yuv420p OUTPUT_FILE
