Comment(by dl-mythtv at catspoiler.org):

 Replying to [comment:9 janne]:

 > Increasing the buffer size for everyone is obviously not the right
 solution. Since this seems to be a common problem with 720p (60 real
 frames per second) video it might make sense to make buffer time constant
 and not frame constant.

 It should be possible to adaptively set the number of buffers.  If the
 decoder thread would block due to a lack of buffers and there is less than
 a certain threshold amount of buffered audio data, then add another video
 buffer instead of waiting for an existing buffer to be made available.
 Tuning the minimum audio buffer threshold would be a bit tricky because it
 would depend on how quickly the decoder thread could process the stream
 until it finds more audio data.
