Matthieu Bouron 22f411378e videoconvert: remove unneeded guint comparaison

Wim Taymans 9b4e2b4b36 videoconvert: disable fastpath for odd width on some formats 2013-09-06 12:45:36 +02:00
Wim Taymans e97f6401de videoconvert: add additional width/height constraints 
Some of the fastpath function can only work with aligned widht/height
so make sure we check this as well when choosing a fastpath.
Add fastpath for I420/YV12 -> BGRx

Wim Taymans ce2b40670a videoconvert: don't convert too much with odd width 2013-09-05 16:26:33 +02:00
Wim Taymans 700afbf6fd videoconvert: handle lines in one go 
Handle odd heights in 1 go when no vertical subsampling is used.

Wim Taymans ce2ad4ae4a videoconvert: fix height round down 2013-09-05 11:04:03 +02:00
Wim Taymans 22da49a55c videoconvert: also allocate temp lines in fastpath 
Some of the fastpath functions need tmplines, so make sure we allocate some in
the fastpath too.

This avoids SEGFAULTs with odd heights.

Wim Taymans 579be969e5 videoconvert: add more fastpaths 
Also reuse the I420 code for YV12 because it can handle the swapped UV fields
just fine.

Wim Taymans c731f1cba0 videoconvert: only chroma subsample when needed 2013-09-03 17:37:14 +02:00
Wim Taymans 10b3b88e9c videoconvert: fix handling of chroma resample 
Increase the number of temporary lines that we need, it is possible that the
up and downsampling offsets are out of phase and that we need to keep some
extra lines around. Also copy the unhandled output lines for the next round
instead of overwriting them.

before pack for higher quality conversions and correct chroma siting.

Wim Taymans 701ae2f144 videoconvert: respect the pack_lines when packing 
Packing is supposed to happen on the amount of lines specified in the format
info. It's currently all set to 1 but that will change.

them operate on the target buffer memory directly.
