[Libva] [ANN] gstreamer-vaapi 0.5.1 (unstable)

[Gwenole Beauchesne]

Hi,

2013/1/31 Li, Jocelyn <jocelyn.li at intel.com>:

> We noticed that some VC-1 changes are committed to 0.4 branch as well.

I could not backport all of them, but just the most significant ones.
i.e. only bug fixes are backported, not features.

> Just double confirm, will 0.4 branch be maintained for a while, right? As you know, some product is still using 0.4 branch.

Yes, I try to maintain at most two branches. However, I expect people
to migrate to 0.6.0 when it comes out after the 0.5.x cycle. :)
Besides, 0.5.x normally works equally well vs. 0.4.x series except for
the MPEG-4:2 decoder for now.

If you think more fixes can be backported, just send a patch. However,
please make sure they work first. I was planning a 0.4.2 release but I
have no feedback yet from other people concerning the Wayland fixes.
So, I did not integrate those yet.

Thanks,
Gwenole.

> * Add simple decoder demo that only uses libgstvaapi
> * Fix thread-safety issues in the Wayland renderer
> * Fix VC-1 decoding bugs #692461, #692312, #692271, #692270, #692267

> - Add support for CLOSED_ENTRY, thus also avoiding an assert() in some VA drivers
> - Fix bitplanes decoding with an odd number of macroblocks
> - Fix a possible buffer overflow while extracting RBDUs from EBDUs
> - Fix various parser bugs related to VOPDQUANT
