  • Fail to set profile to high when using ffmpeg with libx264

    10 mars 2012, par user1258095

    Here is my command :

    ffmpeg -i input.avi -vcodec libx264 -vpre fast -vpre high -acodec copy output.avi

    The output :

    Input #0, avi, from 'short.avi':
    
  Metadata:
    
    encoder         : Lavf53.3.0
    
  Duration: 00:00:25.04, start: 0.000000, bitrate: 12705 kb/s
    
    Stream #0.0: Video: msmpeg4v2, yuv420p, 1920x1080, 24 tbr, 24 tbn, 24 tbc
    
    Stream #0.1: Audio: aac, 48000 Hz, 5.1, s16, 316 kb/s
    
    Metadata:
    
      title           : ED-CM-5.1-DVD-Final2
    
File for preset 'high' not found

    However, I am able to successfully transcode files when setting the profile to baseline or main, from the man page of x264 it is clear that "high" should also be a valid argument. I also want to know where these preset files are located in the file system(I am running ubuntu 11.10) so that I can make sure what arguments I can actually use for presets and profiles at the moment. I am very frustrated by this issue and would really appreciate any input from you guys. Thanks in advance.

  • FFMpeg : Images into video

    12 mars 2012, par Mark

    I'm trying to turn a series of images into a video.

    My idea is to have a very low frame rate so it's essentially a slideshow video for the frames.

    I currently have my images in the following format...

    *1-1.jpg
    *1-2.jpg
    *1-3.jpg
    *1-4-1.jpg
    *1-4-2.jpg
    *1-4-3.jpg
    *2-1.jpg
    *2-2.jpg

    etc...

    So, here's the command I'm trying to run...

    c:\wamp\www\videos\images>c:\ffmpeg\bin\ffmpeg.exe -f image2 -r 1 -i %d-%d.jpg movie.mpg

    This command won't do exactly what I want it to, but it'll let me at least get a test video done.

    Ideally, I'd like to be able to do multiple run throughs via PHP (which will be easy, I think once I get a working command)

    So, on the first run it would process all the images that start with 1, then on the second the ones that start with 2, and so on.

    However, no matter how I format the image section of the command, I get the following error...

    %d-%d.jpg: No such file or directory

    If I just do %d.jpg, I get the same error, but with %d.jpg instead of %d-%d.jpg

    Do you have any ideas how I can get this to work ? If I can get it to work with one set, I can use variables and loops in PHP to get it to process the other videos I'll be making.

    Thanks in advance for any thoughts.
