  • Improve the quality of webm video using ffmpeg

    3 October 2013, by Leke

    I'm trying out two codecs and was wondering if I could improve the results of the webm output ...

    ffmpeg -i test.ts -t 10 -f webm -vcodec libvpx output.webm

    to match the quality of the mp4 output...

    ffmpeg -i test.ts -t 10 -b 1500k -vcodec libx264 output.mp4

    What settings would give me the best webm rip?

    Thanks.

    Edit:
    Here is an error output when trying some rip improvements...

    ffmpeg -i test.ts -c:v libvpx -crf 4 -b:v 1M -c:a libvorbis output.webm

  • ffmpeg not finding audio streams?

    24 September 2013, by Jim Miller

    I'm doing some video conversion with ffmpeg v. N-54271-g7f866c1 (a fresh pull from the git sources in late June 2013) on Fedora 19. One of the things I want to do is to concatenate two videos and then convert the result to an mp4. The following code is working well for me:

    ffmpeg -i video_a.mov -i video_b.mov -acodec libfaac -vcodec libx264 
    
     -preset fast -crf 22  -s 940x528 -pix_fmt yuv420p 
    
     -filter_complex '[0:1] [0:0] [1:1] [1:0]  concat=n=2:v=1:a=1 [v] [a]' 
    
     -map '[v]' -map '[a]' output.mp4

    except for a couple of older hunks of test video I've been using. On those, ffmpeg isn't finding the audio stream, and so the above call dies with ffmpeg complaining that Stream specifier ':1' in filtergraph description [0:1][0:0][1:1][1:0] concat=n=2:v=1:a=1 [v] [a] matches no streams. The catch, of course, is that there is an audio stream in the video; it's just not getting found.

    When ffmpeg starts, I get a description of the input like so:

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/var/www/priv/videorising7/raw_take_video/v2261-MTQxMzgwMDM4NzAx.mov':

    Metadata:
    
      creation_time   : 2011-10-13 16:08:18
    
      handler_name    : Apple Alias Data Handler

    I suppose the video might just be so old (2006?) that I should be lucky that it plays at all. However, I'm able to run these videos through some other ffmpeg jobs (converting from .mov to .mp4, for instance), but those don't require explicitly referencing the audio and video tracks. Any insights out there?
