A very off thing that I've had with the H264 encoder : When encoding video using SW only (on an older Nahelem) the encoded file plays well. When encoding it using Hardware (on an SB), the playback order of the frames seems to be all wrong, causing hiccups.
This was experienced both with Intel's own decoder (inside my software) and an external decoder (VLC), and with the encoder both runnig in my own application, or in sample_encode.
I doubt something like that could have slipped by everyone by now, or could it ?
I'm using version 3.0 beta 2
