Description

After Perian.componenets is installed [newest build and possibly older builds], exporting .mov file with H264 video [such as Apple's HD Trailers] using quicktime pro's export presets [regardless as to what format] will result in video with much lower framerate than the original file. What I see varies from 13-16fps instead of the 24 fps for the original file. [Above mentioned fps is not my decoding rate, but the supposed framerate of the video]

Confirmed, looks like frame stepping isn't working correctly with our H.264 decoder (hitting right on Apple's trailers skips every other frame.) Not really sure why QuickTime handles it differently than when playing normally, maybe it has to do with some of the capability flags that are barely documented.

  • status changed from new to closed.
  • resolution set to fixed.

(In [377]) Look up the buffer for a frame that we're being asked to begin again if it's alreadly been decoded. Fixes #133
