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 Conflicts: configure libavcodec/h263dec.c libavcodec/h264.c libavcodec/ituh263dec.c libavcodec/mjpegdec.c libavcodec/wmalosslessdec.c libavcodec/x86/snowdsp_mmx.c libavformat/mpegts.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
