* avpriv_tempfile: add djgpp fallbackPeter Ross2018-11-28

* hwcontext_opencl: Only release command queue if it existsMark Thompson2018-11-28
| | | | | If the frames context creation fails then the command queue reference need not exist when uninit is called.
* avutil/mem: Fix invalid use of av_alloc_sizeMark Harris2018-11-26
| | | | | | | | | | | 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>

* avutil/mem: Correct documentation of av_fast_*alloc(z)Andreas Rheinhardt2018-11-18
| | | | | | | | | The current wording regarding size and min_size is completely wrong and ignores that min_size is indeed only a desired minimal size, not the actually allocated size.

* lavu/avsscanf: Do not mix declaration and code.Carl Eugen Hoyos2018-11-18
| | | | | | | | Fixes the following warning: libavutil/avsscanf.c: In function 'decfloat': libavutil/avsscanf.c:354:9: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement] int bitlim = bits-3*(int)(rp-9); ^~~
* avutil/cuda_check: Make sure this passes make fate-sourcePhilip Langdale2018-11-17
| | | | | | | | The header guards were unnecessarily non-standard and the c file inclusion trick means the files dont't have standard licence headers. Based on a patch by: Martin Vignali <martin.vignali@gmail.com>
* lavu: add locale-independent sscanf implementationPaul B Mahol2018-11-16
| | | | | | Copied and adopted from musl implementation. * converted all 'long double' to 'double' * removed %m support
* avutil/hwcontext_cuda: Define and use common CHECK_CU()Philip Langdale2018-11-14
| | | | | | | | | | | | | | | | | | We have a pattern of wrapping CUDA calls to print errors and normalise return values that is used in a couple of places. To avoid duplication and increase consistency, let's put the wrapper implementation in a shared place and use it everywhere. Affects: * avcodec/cuviddec * avcodec/nvdec * avcodec/nvenc * avfilter/vf_scale_cuda * avfilter/vf_scale_npp * avfilter/vf_thumbnail_cuda * avfilter/vf_transpose_npp * avfilter/vf_yadif_cuda

* avutil/pixdesc: Add av_write_image_line2(), av_read_image_line2()Michael Niedermayer2018-10-27
| | | | | | | | | This is needed because of 32bit float formats (which are difficult to store in 16bits) This also fixes undefined behavior found by fate Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavc/h264: create AVFrame side data from H.264 timecodesDevin Heitmueller2018-10-23
| | | | | | | | | 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 Li2018-10-11
| | | | | | | | | | | | | | 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 Li2018-10-11
| | | | | | | | | | | | | | | | | 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 Thompson2018-09-23
| | | | | | | | | | | | | | 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.
* | hwcontext_vaapi: Improve logging around quirk detectionMark Thompson2018-09-23
| | | | | | | | | | | | | | Clarify that the list is the naughty list, and therefore being on it is not desirable. The i965 driver does not need to be on the list after version 2.0 (when the standard parameter buffer rendering behaviour was changed).
