  • libav much longer than avconv

    17 mars 2014, par fsulser

    I was using ffmpeg to generate some images from a video. Now I read that I shouldn't use ffmpeg longer and use avconv from libav instead.
    So I tried to do the same thing with avconv.

    The ffmpeg is looking like this :

    ffmpeg -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp

    Same with avconv :

    avconv -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp

    ffmpeg needs less than one second to finish. Avconv about 90 seconds for the same task.
    Is this usual or do I need to change some things to work with avconv ?

  • ffmpeg : create interlaced output from progrssive input

    6 février 2012, par user1190908

    I have a 720p60 (54.94 to be exact) clip that I would like to scale down and output in 540i30 (27.97 to be exact).

    Here is my command line :

    ffmpeg.exe -i clip720p60.m2t -ss 90 -t 30 -vcodec libxvid -s 960x540 -b 1000k -r 29.97 -acodec libmp3lame -ar 22050 -ab 64k -f avi clip540i30.avi
    
...
    
Input #0, mpegts, from 'clip720p60.m2t':
    
  Duration: 01:53:55.76, start: 0.196678, bitrate: 17250 kb/s
    
  Program 1
    
    Stream #0.0[0x1011]: Video: h264, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 59.94 tb(r)
    
    Stream #0.1[0x1100]: Audio: ac3, 48000 Hz, stereo, s16, 384 kb/s
    
Output #0, avi, to 'clip540i30.avi':
    
    Stream #0.0: Video: libxvid, yuv420p, 960x540 [PAR 1:1 DAR 16:9], q=2-31, 1000 kb/s, 29.97 tb(c)
    
    Stream #0.1: Audio: libmp3lame, 22050 Hz, stereo, s16, 64 kb/s
    
...

    The first options indicates to encode 30s at 90s past the start.

    Whatever options I tried up to now always end up with a video stream of 60s and an audio stream of 30s in the output clip.

    Can any one help me ?
