Merge remote-tracking branch 'qatar/master'
* qatar/master:
mpeg12: fixed parsing in some mpeg2 streams
Add SMPTE240M transfer characteristics flag.
mpegts: Some additional HDMV types and reg descriptors for mpegts
motionpixels: Clip YUV values after applying a gradient.
jpeg: handle progressive in second field of interlaced.
ituh263dec: Implement enough of Annex O (scalability) to fix a FPE.
h263: more strictly forbid frame size changes with frame-mt.
h264: additional protection against unsupported size/bitdepth changes.
tta: prevents overflows for 32bit integers in header.
configure: remove malloc_aligned.
vp8: update frame size changes on thread context switches.
snowdsp: explicitily state instruction size.
wmall: fix reconstructing audio with uncoded channels
WMAL cosmetics: fix indentation
gitignore: add Win32 library suffixes
