* lavc: Move start code finding to utils.cMartin Storsjö2013-03-26
| | | | | | | | | | This allows dropping the mpegvideo dependency from a number of components. This also fixes standalone building of the h264 parser, which was broken in 64e438697. Signed-off-by: Martin Storsjö <martin@martin.st>
* ape: 3.80-3.92 decoding supportKostya Shishkov2013-03-25

| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: consistently use unaligned movs in the unaligned bswapJanne Grunau2013-03-25
| | | | Fixes fate errors in asv1, ffvhuff and huffyuv on x86_32.

* tscc2: allocate AVFrame properly.Anton Khirnov2013-03-22

* h264: remove redundant freeing of DPB in h264_decode_endAnton Khirnov2013-03-21
| | | | free_tables() frees it already.
* h264: add a parameter to the CHROMA444 macro.Anton Khirnov2013-03-21
| | | | This way it does not look like a constant.
* h264: add a parameter to the CHROMA422 macro.Anton Khirnov2013-03-21
| | | | This way it does not look like a constant.
* h264: add a parameter to the CABAC macro.Anton Khirnov2013-03-21
| | | | This way it does not look like a constant.
* h264: add a parameter to the FIELD_OR_MBAFF_PICTURE macro.Anton Khirnov2013-03-21
| | | | This way it does not look like a constant.
* h264: add a parameter to the FIELD_PICTURE macro.Anton Khirnov2013-03-21

| | | | This way it does not look like a constant.
* h264: merge common_init() into ff_h264_decode_init.Anton Khirnov2013-03-21
| | | | There is no point in keeping those separate.
* h264: make ff_h264_frame_start static.Anton Khirnov2013-03-21
| | | | It is not called from outside h264.c
* h264: fix bit depth changes with frame threadingJanne Grunau2013-03-20
| | | | | | | | | AVCodecContext.bits_per_raw_sample is updated from the previous thread in the generic update function before the codec specific update_thread function is called. The check for reinitialization of dsp functions uses bits_per_raw_sample. When called from update_thread_context it will be already at the current value and the dsp functions aren't updated if only the bit depth changes.
* mpegvideo: allocate hwaccel privdata after the frame bufferHendrik Leppkes2013-03-19
| | | | | | | | | | This ensures the hwaccel privdata does not leak when a frame buffer could not be allocated (and toggle the assert when the frame is re-used). Having no frame buffer available is quite common when using the DXVA2 hwaccel in situations where the DXVA2 renderer is being re-allocated, for example when moving between displays.

* lavc, lavfi: fix counting number of planes in AVBufferRef wrappersAnton Khirnov2013-03-19
| | | | | | Number of planes is not always equal to the number of components even for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components in two planes.
* mpeg12: do not fail on zero dimensions in the sequence header.Anton Khirnov2013-03-18
| | | | | | | | | | | | The total frame size is a combination of the 12 bits in the sequence header and 2 more bits in the the sequence extension. While the specification explicitly forbids the dimensions from the sequence header from being 0 (thus ruling out multiples of 4096), such videos apparrently exist in the wild so we should attempt to decode them. Based on a patch by Michael Niedermayer <michaelni@gmx.at> Fixes Bug 416.
* lavc,lavfi: fix calculating the plane size in the AVBufferRef wrappersAnton Khirnov2013-03-17
| | | | | It is supposed to be height * linesize, not width * linesize. Thanks to Hendrik Leppkes for pointing out the bug.
* atrac3: avoid oversized shifting in decode_bytes()Xi Wang2013-03-15
| | | | | | | | | | | | | | When `off' is 0, `0x537F6103 << 32' in the following expression invokes undefined behavior, the result of which is not necessarily 0. (0x537F6103 >> (off * 8)) | (0x537F6103 << (32 - (off * 8))) Avoid oversized shifting.

* add support for Monkey's Audio versions from 3.93Kostya Shishkov2013-03-15

* ape: provide two additional bytes in buffer for old MAC versionsKostya Shishkov2013-03-15
| | | | Range coder in 3.90-3.95 overread two bytes in the final normalize.
* ape: make version-dependent decoding functions called via pointersKostya Shishkov2013-03-15
| | | | | | | This will help in supporting old versions, e.g. version 3.93 uses the same range coder but different predictor and version 3.82 uses different range coder and predictor. Also this should not make decoding newer versions slower by introducing additional checks on versions.
* vaapi: fix argument for ff_vaapi_common_end_frame callJanne Grunau2013-03-14

|
* Add av_log_{ask_for_sample|missing_feature} replacements to libavutilDiego Biurrun2013-03-13
| | | | | This allows reporting missing features and requesting samples from all libraries in a standard way; with a simplified API.

* avframe: call release_buffer only if it is setJanne Grunau2013-03-11
| | | | | | AVCodecContext release_buffer() shall be NULL for audio codecs using get_buffer. The backward compatibility code hence have to check before calling it.
* pthread: unref the decoded but not returned frames on close.Anton Khirnov2013-03-11
| | | | | Fixes memleaks when frame mt is used and the decoder is not flushed at the end.

* h264: remove a useless svq3 conditionAnton Khirnov2013-03-11

* mpegvideo: remove useless references to h264 and svq3Anton Khirnov2013-03-11
| | | | | The h264 decoder does not use mpegvideo anymore. The svq3 decoder only uses ff_draw_horiz_band().
