Set the flag MFX_BITSTREAM_COMPLETE_FRAME when it is a progressive picture. This can fix vc1 decoding segment fault issues because can't set the start code correctly. See: ./avconv -hwaccel qsv -c:v vc1_qsv -i /fate-suite/vc1/SA00040.vc1 -vf "hwdownload, format=nv12" -f rawvideo /dev/null v2: fix some h264 interlaced clips regression a. field_order of some h264 interlaced video (e.g: cama3_vtc_b.avc) is marked as AV_FIELD_UNKNOWN in h264_parser.c. This is not a completed frames. So only set the MFX_BITSTREAM_COMPLETE_FRAME when it is progressive. b. some clips have both progressive and interlaced frames (e.g.CAPAMA3_Sand_F.264), the parsed field_order maybe changed druing the decoding progress. This patch has been verified for other codecs(mpeg2/hevc/vp8). Signed-off-by: Zhong Li <zhong.li@intel.com> Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>
