I went through the old builds and 0901 plays it fine, with 0902 the video freezes shortly before the end (later than with the current builds, so not clearly visible with the sample in my previous post). Not sure if this info is helpful, that was the switch from newclock3 to newclock4...

I have looked into this.
Thanks a lot!

I believe all HW codecs lose the final frames because of this. It just turns out that due to the larger amount of buffering in MMAL decoder it loses more.
Ah, very interesting! That would explain why it has been unnoticed before. Not sure how much buffering VDPAU uses, on my somewhat old 8600GTS and 8600GT cards I couldn't see any visible glitches.

Quote:I'll see if something can be done.
We could limit the amount data pushed into the codec (but this may harm performance when the stream is difficult).
We could try to make dvdplayer continue prodding the codec after the final frame has been submitted (theoretically better, but a more intrusive change).
The latter sounds like the better solution. Buffers can be nasty, had to deal with similar issues on serial and network devices several times myself...

Anyways: good luck and thanks a lot for looking into that issue!

so long,

Hias
