* h264: factor out calculating the POC count into a separate fileAnton Khirnov2016-04-24
| | | | This will allow decoupling the parser from the decoder.
* h264_parser: move the H264DSPContext to the parser contextAnton Khirnov2016-04-24
|
* h264: decouple h264_ps from the h264 decoderAnton Khirnov2016-04-24
| | | | | | | | | Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.
* h264_parser: eliminate H264SliceContext usageAnton Khirnov2016-04-24
| | | | It is no longer needed for anything.
* h264_parse: make sure the ref count is zeroed on all failure pathsAnton Khirnov2016-04-24
|
* h264: factor out parsing the reference count into a separate fileAnton Khirnov2016-04-24
| | | | This will allow decoupling the parser from the decoder.
* h264: stop testing whether the reference count changes in ff_set_ref_count()Anton Khirnov2016-04-24
| | | | It is no longer necessary after 741b494fa8cd28a7d096349bac183893c236e3f9
* h264: move reading direct_spatial_mv_pred out of ff_set_ref_count()Anton Khirnov2016-04-24
| | | | | It has nothing to do with the reference count and so does not belong in this function.
* h264_parser: switch to h2645_parse for NAL unescapingAnton Khirnov2016-04-24
| | | | Remove now unused ff_h264_decode_nal().
* h264_mp4toannexb_bsf: do not fail on annex B extradataAnton Khirnov2016-04-24
| | | | | Just pass through the bitstream as is. This is the same as what is done for HEVC already.

* libxvid: Create extradata in init using a dummy frameDerek Buitenhuis2016-04-19
| | | | | | | | | | | Modifying global header extradata in encode_frame is an API violation and only happens to work currently because mov writes its header at the end of the file. Heavily based off of a patch from 2012 by Nicolas George. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* lavc: move the vaapi encoders further down in the list of codecsAnton Khirnov2016-04-15
| | | | | | | Right now they are the first encoders for those codecs in the list, so they are selected when the caller requests a codec by id. Since they require special treatment, they should not be selected by default if there are other encoders (e.g. libx264/5) available.

* omx: Add support for zerocopy input of framesMartin Storsjö2016-04-12
| | | | | | | | | | | This can only be used if the input data happens to be laid out exactly correctly. This might not be supported on all encoders, so only enable it with an option, but enable it automatically on raspberry pi, where it is known to be supported.

* omx: Add support for broadcom OMX on raspberry piMartin Storsjö2016-04-12
| | | | | | | | | | | | | | | | The raspberry pi uses the alternative API/ABI for OMX; this makes such builds incompatible with all the normal OpenMAX implementations. Since this can't easily be detected at configure time (one can build for raspberry pi's OMX just fine using the generic, pristine Khronos OpenMAX IL headers, no need for their own extensions), require a separate configure switch for it instead. The broadcom host library can't be unloaded once loaded and started; the deinit function that it provides is a no-op, and after started, it has got background threads running, so dlclosing it makes it crash.

* screenpresso: Correctly handle keyframesVittorio Giovara2016-04-04
| | | | | | | | The first byte contains compression level together with keyframe status. When a frame is not interpreted correctly, its data is summed to the reference, and would degrade over time, producing an incorrect result. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* vaapi_h264: Fix bit offset of slice data.Mark Thompson2016-04-02
| | | | | | | | | | | | Commit ca2f19b9cc37be509d85f05c8f902860475905f8 modified the meaning of H264SliceContext.gb: it is now initialised at the start of the NAL unit header, rather than at the start of the slice header. The VAAPI slice decoder uses the offset after parsing to determine the offset of the slice data in the bitstream, so with the changed meaning we no longer need to add the extra byte to account for the NAL unit header because it is now included directly.

* ac3dec: change logging of skipped E-AC-3 substreams.Tim Walker2016-04-02
| | | | | | | | | Change log level from warning to debug: the E-AC-3 "core" substream can be successfully decoded without the additional and dependent substreams, and their presence is already indicated via avpriv_request_sample in ff_eac3_parse_header.

* eac3dec: don't call avpriv_request_sample every frame.Tim Walker2016-04-02
| | | | | | | | These errors neither prevent nor stop successful decoding of the E-AC-3 stream's "core", causing avpriv_request_sample to be called for every single frame in the bitstream. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
