* Drop Windows XP support remnantsDiego Biurrun2018-04-09

* w32pthreads: always use Vista+ API, drop XP supportwm42018-04-09
| | | | | | | | | | | | This removes the XP compatibility code, and switches entirely to SRW locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore.

* lavc/qsvdec: set complete_frame flags for progressive pictureZhong Li2018-04-08
| | | | | | | | | | | | | | | | | | | | | 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>
* qsv: adding Multi Frame Encode supportMaxym Dmytrychenko2018-04-08
| | | | | | | | | | | | | | | | Starting from API 1.25 helps to improve performance of the simultaneous encode, 1:N scenario, like: ./avconv -y -hwaccel qsv -c:v h264_qsv -r 30000/1001 -i ~/bbb_sunflower_1080p_60fps_normal.mp4 -vframes 600 -an \ -filter_complex "split=2[s1][s2]; [s1]scale_qsv=1280:720[o1]; [s2]scale_qsv=960:540[o2]" \ -map [o1] -c:v h264_qsv -b:v 3200k -minrate 3200k -maxrate 3200k -f rawvideo /tmp/3200a.264 \ -map [o2] -c:v h264_qsv -b:v 1750k -minrate 1750k -maxrate 1750k -f rawvideo /tmp/1750a.264 Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>
* lavf/qsvvpp: bypass vpp if not needed.Zhong Li2018-04-08
| | | | | | | | | | Currently vpp pipeline is always created, even for the unnecessary cases such as setting the option "vpp_qsv=w=1280:h=720" for an input with native resolution 1280x720. Thus introduces unnecessary performance dropping, so bypass vpp if not needed. Signed-off-by: Zhong Li <zhong.li@intel.com> Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>
* lavc/qsvdec: expose frame pic_type and key_frameZhong Li2018-04-08
| | | | | | | | | | | | | Currently pict_type and key_frame are unset. Add an extra param to fetch the picture type from qsv decoder The judgement “key frame is equal to IDR frame” only suitable for H264. For HEVC, all IRAP frames are key frames, and other codecs have no IDR frame.

* qsv: align surface width/height to 16.Ruiling Song2018-03-21
| | | | | | | | | | Per MediaSDK documentation, it requires width/height to 16 alignment. Without this patch, hwupload pipeline may fail if 16 alignment is not met. Although this patch also apply 16 alignment to qsv encoder/decoder, it will not bring any side-effect to them as they are already aligned.

* configure: Don't assume a 16 byte aligned stack on BSDs on i386Martin Storsjö2018-03-17
| | | | | | | | | | | With GCC, request it to maintain 16 byte alignment, and the existing entry points already align it via attribute_align_arg. With clang, do the same as for mingw; disable the aligned stack and let the assembly functions that require it do the alignment instead. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Don't assume an aligned stack on clang on windowsMartin Storsjö2018-03-13
| | | | | | | | | | | | | | | | | If we'd enable a 16 byte aligned stack, clang/llvm would also assume that alignment everywhere and produce code that strictly requires it. That would require adding realignment (via attribute_align_arg) on every single public library function or enable -mstackrealign (which does the same on every single function). Also relatedly; the parameter currently tested (-mllvm -stack-alignment=16) hasn't actually been supported for quite some time; current clang versions use -mstack-alignment=16 for the same. Actually testing for that parameter would be a different change though, since it has a real risk of changing behaviour on any other platform where clang is used.

* amf: Replace writer_id option with LIBAV_AMF_WRITER_ID constantAlexander Kravchenko2018-03-07
| | | | | | | | | | AMFTraceWriter is an abstraction to configure how AMF outputs its logs for the current process and can be configured to output different levels of trace output. If multiple LibavWriter objects are used in one process, there will be duplication of output in av_log. Use a constant writer_id to prevent this scenario.
