    lavf/dashenc : Write media trailers when DASH trailer is written.

    This commit ensures that all (potentially, long) filesystem activity is
    
performed when the user calls av_write_trailer on the DASH libavformat
    
context, not when freeing the context. Also, this defers media segment
    
deletion until after the media trailers are written.

  • I can't find a good C# Media Transcoding Library [closed]

    11 mai 2021, par TheYoungSeth

    I am trying to find a good c# library for media transcoding, primarily video, and I don't seem to find anything good and actually usable. I do not want to use FFMpeg wrappers because I want my program to be user friendly and for public use which I can't do with FFMpeg because of the harsh usage rules that come with it.

    


    Help would be appreciated,
thanks

    


  • Getting media duration with ffprobe after decoding with FFmpeg

    23 août 2019, par Brad

    With ffprobe, it’s possible to get the duration of a media file :

    ffprobe -show_format 1064428_cityLights_HD_BG.mp4

    [FORMAT]
    …
    duration=10.010000

    However, ffprobe only digs into the container and doesn’t decode the media. For container formats that have no inherent duration, or for broken files that play but maybe weren’t finalized, the duration isn’t available :

    [FORMAT]
    …
    duration=N/A

    The recommended solution to this problem is to use FFmpeg to decode, and then parse STDERR.

    ffmpeg -i input.webm -f null -

    frame=206723 fps=1390 q=-0.0 Lsize=N/A time=00:57:28.87 bitrate=N/A speed=23.2x

    This works well enough, but if I’m integrating this into other programs and scripts, I have to assume that the output of FFmpeg isn’t going to change from version to version. It would be much more convenient if there were a way to use ffmpeg and ffprobe together, so that I could continue to utilize the JSON output of ffprobe.

    Is there some way to force ffmpeg to decode the media and pipe it to ffprobe in some way that allows ffprobe to include the duration in its output for these types of situations ?

    (Note : I know I can just have FFmpeg output a file, and then input that into ffprobe. For convenience, I’m curious if there’s an all-in-one solution, with a pipe or equivalent.)
