  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • Converting with ffmpeg a .mov to uncompressed .avi results in a black screen in virtualdub [migrated]

    28 mai 2013, par TazgerO

    I am trying to convert a .mov to an uncompressed .avi with ffmpeg. As I want no quality loss, I am using the following ffmpeg command :

    ffmpeg -i toto.mov -vcodec copy -y toto.avi

    The convertion works perfectly (the video works in VLC) except that when I am opening the file with virtualdub I get a black screen.

    In VirtualDub, under file information I get the following :

    Frame size: 800x600, 30.000fps
    
Length: 802 frames
    
Decompressor: Internal DIB decoder

    If I am not specifying the -pix_fmt and -vcodec arguments, ffmpeg convert to mpeg-4 and yuv420p but I am loosing on the quality as my file shrunk to about 400Mo to 1Mo but the video works in virtualdub and this time the Decompressor is set to ffdshow Video Codec (FMP4). I doubt this is a ffdshow as I had another video working perfectly with the internal DIB decoder.

    Any idea, to get the image in virtualdub ?

  • FFMPEG trim video resulting not moving videos and black video with audio

    13 juin 2023, par Rafliii

    I tried to trim my video based on start and end time with the following code :

    


    ffmpeg -ss 02:06:30.500 -to 02:06:32.417 -i movie.mp4 -c copy output.mp4

    


    The output video is not moving video and some of them are black videos with audio. What should I do ?

    What should I do ?

    


  • trimming video with FFMPEG, but the output is a black video, with audio

    18 juillet 2017, par riancu

    i have a video, and i want to trim it. This is what I am doing :

    ffmpeg -i input.mp4 -ss 0 -t 4 -vcodec copy -acodec copy output.mp4

    However, output.mp4 only provides me with the correct audio — the video is just a black screen

    I found a similar issue, and someone said to add -pix_fmt yuv420p
    I added it, but nothing changed (did i add it incorrectly ?)

    Any thoughts ?
