Description Sebastian Dröge (slomo) 2008-02-27 07:40:22 UTC 
Hi,
the wildmidi element currently does not handle seeking correctly. First, seeking does not work at all it seems and then the error reporting seems to be a bit too hard:

    libWildMidi(WildMidi_Init:3707): ERROR Library not Initialized
    ** Message: don't know how to handle audio/midi
    ** Message: Error: A audio/midi decoder plugin is required to play
    this stream, but not installed.
    gstdecodebin.c(792): close_pad_link (): /play/decodebin1:
    No decoder to handle media type 'audio/midi'

    ** Message: Missing plugin: gstreamer|0.10|totem|audio/midi
       decoder|decoder-audio/midi (audio/midi decoder)
       ** Message: Automatic missing codec installation not supported (helper
          script missing)


So wildmidi should check for errors while seeking and handle them better (i.e. plya from the current position instead of exploding) and then seeking should made to work somehow ;)

    wildmidi: cleanups and fix seeking
    
    Remove time_per_frame, it's too inaccurate.
    Fix convert for -1 values.
    Use scaling to convert samples to time.
    Fix segment handling.
    Fix seeking.
    Fix buffer clipping (not yet enabled)
    Protect the WildMidi library with the object lock to avoid races when changing
    properties.
    Fix offsets on output buffers, for raw audio the offset contains the sample
    position not byte position.
    Add better DISCONT handling.
    
    Fixes #519001
