* avutil/softfloat_ieee754: Fix odd bit position for exponent and sign in ↵Michael Niedermayer2020-01-061-1/+1

* avutil/mem: Fix invalid use of av_alloc_sizeMark Harris2019-07-231-1/+1
| | | | | | | | | | | | The alloc_size attribute is valid only on functions that return a pointer. GCC 9 (not yet released) warns about invalid usage: ./libavutil/mem.h:342:1: warning: 'alloc_size' attribute ignored on a function returning int' [-Wattributes] 342 | av_alloc_size(2, 3) int av_reallocp_array(void *ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 4361293fcf59edb56879c36edcd25f0a91e0edf8)
* avutil/avstring: Fix bug and undefined behavior in av_strncasecmp()Michael Niedermayer2019-06-271-2/+3
| | | | | | | | | | | The function in case of n=0 would read more bytes than 0. The end pointer could be beyond the allocated space, which is undefined.

* lavc/h264: create AVFrame side data from H.264 timecodesDevin Heitmueller2018-10-232-0/+9
| | | | | | | | | Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing info. For framerates > 30 FPS, the field flag is used in conjunction with pairs of frames which contain the same frame timestamp in S12M. Ensure the field is properly set per the spec.
* lavu/qsv: make a copy as libmfx alignment requirement for uploadingZhong Li2018-10-111-2/+29
| | | | | | | | | | | | | | Libmfx requires 16 bytes aligned input/output for uploading. Currently only output is 16 byte aligned and assigning same width/height to input with smaller buffer size actually, thus definitely will cause segment fault. Can reproduce with any 1080p nv12 rawvideo input: ffmpeg -init_hw_device qsv=qsv:hw -hwaccel qsv -filter_hw_device qsv -f rawvideo -pix_fmt nv12 -s:v 1920x1080 -i 1080p_nv12.yuv -vf 'format=nv12,hwupload=extra_hw_frames=16,hwdownload,format=nv12' -an -y out_nv12.yuv It can fix #7418 Signed-off-by: Zhong Li <zhong.li@intel.com>
* lavu/hwcontext_qsv: Add support for AV_PIX_FMT_BGRA.Zhong Li2018-10-111-10/+34
| | | | | | | | | | | | | | | | | RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending. So add AV_PIX_FMT_BGRA format support. One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv -filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10' -c:v h264_qsv -y out.mp4 Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion. V2: Add P010 format support else will introduce HEVC 10bit encoding regression. Thanks for LinJie's discovery.

* | hwcontext_vaapi: Improve format mappingMark Thompson2018-09-231-57/+76
| | | | | | | | | | | | | | Give the entries in the VAAPI format map table an explicit type and add functions to do the necessary lookups. Add another field to this table indicating whether the chroma planes are swapped (as in YV12), and use that rather than explicit comparisons where swapping is needed.
