  • Audio PTS is not equal but play time is equal

    20 juillet 2023, par KaGa Wu

    I have a video which has an dubbed Portuguese audio stream. The stream does not have the video head, like BGM of companies playing logos. So, the audio stream to delay some time play, it's first data package PTS is 9s. Then I transcode the audio stream to AAC, it's first package PTS is 2s. In my thinking the audio stream put the first data package in more front, it will play in more front originally, but it plays delay time is right !

    


    Here is the first package PTS, origin and transcoded.

  • avformat/matroskaenc : Avoid allocation for Cues

    avformat/matroskaenc : Avoid allocation for Cues

    Up until now, the Matroska muxer would allocate a structure containing
    
three members : The segment offset, a pointer to an array containing Cue
    
(index) entries and a counter for said array. It is unnecessary to
    
allocate it separately and it is unnecessary to contain the segment
    
offset in said structure, as it duplicates another field contained in
    
the MatroskaMuxContext. This commit implements the corresponding
    
changes.

  • hlsenc : Don’t reset the number variable when wrapping

    6 juin 2013, par Carl Eugen Hoyos
    hlsenc : Don’t reset the number variable when wrapping

    The counter itself shouldn’t be wrapped, since it is used for
    
determining end_pts for the next segment - only wrap the number
    
used for the segment file name.
