* Changelog: add VAAPI VP8 decoderMark Thompson2017-11-281-0/+1

* avformat/mov: return correct value in mov_read_cmovPan Bian2017-11-281-0/+1
| | | | | | | On some failure paths, the error code is not correctly set. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avformat/mov: set correct error code in mov_read_customPan Bian2017-11-281-1/+3
| | | | | | | | | In function mov_read_custom(), it returns 0 on the path that av_malloc() returns a NULL pointer. 0 indicates success. An error code should be assigned to ret. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avcodec: set correct return value in ff_mpeg_ref_picturePan Bian2017-11-281-1/+3
| | | | | | | | | | In function ff_mpeg_ref_picture(), it returns 0 on the error path that the return value of av_buffer_ref() is NULL. 0 indicates success, which seems to deviate from the fact. Set ret to AVERROR(ENOMEM) to propagate the error status to the callers. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* Free extradata before reallocating.Dale Curtis2017-11-281-0/+1

* avfilter/drawbox: rename variable for maximum thicknessGyan Doshi2017-11-282-3/+4
| | | | | | | | | The present value name for maximum thickness is 'max' which results in a parse error of any thickness expression containing 'max(val1,val2)'. Value renamed to 'fill'. Tested locally and documented. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat/hlsenc: Fixed initial setting for end_ptsKarthick J2017-11-281-1/+3
| | | | | | | | | | This patch fixes Bug #6868 Sometimes end_pts is getting initialized to audio stream's first pts, while the duration is calculated based on video stream's pts. In this patch the end_pts is initialized with the correct stream's first pts. Reviewed-by: Steven Liu <lq@onvideo.cn> Tested-by: beloko

* ffmpeg: Check read_ffserver_streams() return valuePan Bian2017-11-281-0/+2
| | | | | | | | | | | The function avformat_alloc_context() will return a NULL pointer on failure. However, in function read_ffserver_streams(), its return value is not validated and the subsequent dereference may result in a bad memory access bug. Check its return value against NULL and avoid potential NULL dereference. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat/avienc: fix fields-per-frame value for interlaced video streamsTobias Rapp2017-11-273-14/+33
| | | | | | | | | | | | Writes one set of field framing information for progressive streams and two sets for interlaced streams. Fixes ticket #6383. Unfortunately the OpenDML v1.02 document is not very specific on what value to use for start_line when frame data is not coming from a capturing device, so this is just using 0/1 depending on the field order as a best-effort guess.

* avcodec/nvdec: More effort to make vp8 compile with gcc < 4.6Philip Langdale2017-11-261-11/+10
| | | | | | | | | | | I'm told my prefix work-around wasn't enough to make it compile, although I'm not sure why; I did some basic testing and that approach appeared to work, but I'm not in a position to do a full compile on CentOS 6 so I can't be sure of anything. I have had it confirmed that the additional change to not use named initialisers is enough to make it compile, so let's throw that into the mix too.
* avcodec/nvdec: Make vp8 initialisation more 'compatible'Philip Langdale2017-11-261-5/+14
| | | | | | | | | | | | | | | | | Ancient versions of gcc (pre 4.6) can't directly initialise members of anonymous inner unions/structs by name. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Unfortunately, RHEL 6 shipped with one of these ancient versions and so we're stuck with it until approximately the heat death of the universe. Putting explicit braces into the initialisation is possibly a work-around but the behaviour there was never fully understood before direct initialisation was made to work. So, this may or may not work.

|
* vaapi_decode: Ignore the profile when not usefulMark Thompson2017-11-261-1/+2
| | | | | Enables VP8 decoding - the decoder places the the bitstream version in the profile field, which we want to ignore.
* vaapi: Add VP8 decode hwaccelMark Thompson2017-11-265-0/+248
|
* vp8: Add hwaccel hooksMark Thompson2017-11-263-68/+172
| | | | | | | | | | Also adds some extra fields to the main context structure that may be needed by a hwaccel decoder. The current behaviour of the WebP decoder is maintained by adding an additional field to the VP8 decoder private context to indicate that it is actually being used as WebP (no hwaccel is supported for that case).
* vaapi: Make the decode profile matching more explicitMark Thompson2017-11-261-11/+9
| | | | | Also fixes a bug where it could attempt to decode with an unsupported codec if allow-profile-mismatch was set.
* ffmpeg: Use codec hardware config to configure hwaccelsMark Thompson2017-11-264-133/+251
| | | | | Removes specific support for all hwaccels supported by the generic code (DXVA2, D3D11VA, NVDEC, VAAPI and VDPAU).
* lavc: Mark all AVHWAccel structures as constMark Thompson2017-11-2629-101/+104

* lavc: Delete all fake hwaccelsMark Thompson2017-11-267-151/+6
| | | | They are now unused.
* lavc: Remove register mechanism for hwaccelsMark Thompson2017-11-262-83/+1
| | | | | | | There is no longer any need for a list of them at runtime, because decoders now carry the pointers to their associated hwaccels internally. The file containing external declarations is now used to make the list of hwaccels for configure.
* lavc: Deprecate av_hwaccel_next() and av_register_hwaccel()Mark Thompson2017-11-264-13/+26
|
* lavc: Use hardware config information in ff_get_format()Mark Thompson2017-11-264-94/+211
| | | | | | | | | | | | | | | This removes the dependency that hardware pixel formats previously had on AVHWAccel instances, meaning only those which actually do something need exist after this patch. Also updates avcodec_default_get_format() to be able to choose hardware formats if either a matching device has been supplied or no additional external configuration is required, and avcodec_get_hw_frames_parameters() to use the hardware config rather than searching the old hwaccel list. The FF_CODEC_CAP_HWACCEL_REQUIRE_CLASS mechanism is deleted because it no longer does anything (the codec already contains the pointers to the matching hwaccels).
* lavc: Add hardware config metadata for decoders supporting hardware outputMark Thompson2017-11-2616-1/+372
| | | | | | | | | This includes a pointer to the associated hwaccel for decoders using hwaccels - these will be used later to implement the hwaccel setup without needing a global list. Also added is a new file listing all hwaccels as external declarations - this will be used later to generate the hwaccel list at configure time.
