* avcodec/videotoolbox: use decode_params to propagate H264 PPS changes and ↵Aman Gupta2017-11-13
| | | | | | | | | | | | | | | | | | | | | restart on SPS changes This fixes decoding of H264 video samples with SPS and PPS changes. See for example https://s3.amazonaws.com/tmm1/videotoolbox/spschange.ts, which previously stalled the decoder and failed to produce any new frames after the SPS change. Also see https://s3.amazonaws.com/tmm1/videotoolbox/ppschange.ts, which uses multiple PPS and would previously cause VT decode failures. If the VideoToolbox session needs to be restarted, and videotoolbox_start() fails for some reason (for instance, if the video is interlaced and the decoder is running on iOS), avcodec will return AVERROR_EXTERNAL. This can be used by the API user to switch to another decoder. Signed-off-by: Aman Gupta <aman@tmm1.net>
* avcodec/h264: implement new decode_params callback for PPS/SPSAman Gupta2017-11-13
| | | | | | | | | This callback will be used by the VideoToolbox H264 hwaccel so that it can receive SPS and PPS NALUs. VideoToolbox requires PPS changes to be fed into the decoder session, and for the session to be recreated when the SPS changes. Signed-off-by: Aman Gupta <aman@tmm1.net>

* avcodec/h264, videotoolbox: return AVERROR_INVALIDDATA when no frames are ↵Aman Gupta2017-11-13
| | | | | | | | | | | | | | produced The only reason videotoolbox wouldn't produce frames is if the data fed to it was invalid, so returning AVERROR_INVALIDDATA makes sense here. Further, it means AVERROR_EXTERNAL can be used in further commits to signal fatal VideoToolbox errors, letting the user know that they need to fallback to another decoder.

* avcodec/videotoolbox: reset bitstream_size in end_frameAman Gupta2017-11-13
| | | | | | | | | | | This allows decode_slice to be invoked multiple times before end_frame, causing slices to accumulate before being fed into the VT decoder. An upcoming commit will re-use decode_slice for parameter NALUs, so they can be propagated into the VT decoder session along with slice data. Signed-off-by: Aman Gupta <aman@tmm1.net>

* Fix missing used attribute for inline assembly variablesThomas Köppe2017-11-13
| | | | | | | | | | | | | Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | | | | | | | | | This avoids issues linking to a DLL version of libspeex, since the libspeex headers lack proper dllimport declarations for the data symbols. This isn't an issue when building with mingw with GNU binutils, since GNU ld can fix up that kind of data import automatically. libspeexdec.c already uses speex_lib_get_mode as well.

| * vaapi: Always free parameter buffers after vaEndPicture() with libva2Mark Thompson2017-10-25
| | | | | | | | | | | | This is an ABI change in libva2: previously the Intel driver had this behaviour and it was implemented as a driver quirk, but now it is part of the specification so all drivers must do it.

| | | | | | | | | | | | This has been deprecated in libva2 because hardware does not and will not support it. Therefore never consider it for decode, and for encode assume the user meant constrained baseline profile instead.

| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.

| * qsv: Make the hevc idr_interval consistent with the h264 oneLuca Barbato2017-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the MediaSDK documentation the idr_interval value has a different meaning depending on the codec: 0 in H264 means make every I-frame IDR, in HEVC it means to have it only at the beginning. 1 in H264 means every other I-frame is not-IDR, in HEVC it means that every I-frame is IDR. Keep the behaviour consistent between the two encoders by increasing by 1 internally the idr_interval value for HEVC.
