  • Theora puts incorrect PTS presentation time on video with held frames

    17 mars 2012, par hexatron

    I have a problem with the packet PTS/DTS on OGG Theora videos with held frames.
    Theora tries to be clever about held frames by omitting duplicate frames
    and using the packet PTS/DTS (they are equal) to skip the held frame time.

    For example, a 2-second-long 10 fps video with frames
    
  A A A A A A A A A A B C D E F G G G G G
    
should encode with PTS (the frame start) as (note the encoder adds some dup frames)
    
    A 0.0
    
    A 0.1
    
    B 1.0
    
    C 1.1
    
    D 1.2
    
    E 1.3
    
    F 1.4
    
    G 1.5
    
    G 1.9
    
But libtheora (and ffmpeg) put an incorrect time stamp on frame B
    
(the first frame following a the dup frames)
    
    B 0.6
    
This causes video to hiccup on the mislabeled frame.
    

    
My crude fix for this is to use
    
    current frame PTS =  (next frame PTS time) - (one frame time)
    
and
    
    last frame PTS = duration - (one frame time)

    (I tried submitting a bug report for theora at xiph.org, as the theora site recommends, but could not figure out how to register for a login. I also noticed the reports were several years old, so decided to document this behavior here)

  • Flv video time is shorter than normal when using flv segment in osmf

    7 janvier 2013, par David

    I am working on a project to use flv segments rather than a normal video clip. We use ffmpeg to split a mp4 file into several flv files with headers. The duration of each flv file is 5 second with 15 fps. Given a 10 minutes of video file, after split it, the osmf player only indicates 9:53 as timescale after all content played.

    The code is very simple, after download each flv segment, we use appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN) and appendBytes() to join all segments.

    Can anyone help me out ? Thanks a lot.
