  • FFmpeg AVI recording for H264 @ 1fps not working

    27 février 2012, par Alam

    I am recording H.264 (640x480 @1fps 10seconds) in avi container using FFMPEG. When I play the recorded file in VLC, it plays only first frame and rest of the frames are not played. I am getting

    main warning : late picture skipped (555293 > -305)

    Output of ffprobe is :

  • Converting Real Media with ffmpeg

    7 août 2013, par Eric Arenson

    I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I'm able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

    [avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

    It may have something to do with the funky format of these Real Media files :

    Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?
