* swscale/x86/rgb2rgb: add support for AVXMichael Niedermayer2014-01-21
| | | | | | This does not yet include any actual AVX code Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc: do not force the emu edge flagAnton Khirnov2014-01-21
| | | | | | | The default get_buffer2() implementation (and possibly some user ones) does not allocate edges when this flag is set, which may expose bugs in some decoders. Until the 10 release is out, it is safer to remove this part.

* dxva2: Retry IDirectXVideoDecoder_BeginFrame()Sam Lantinga2014-01-21
| | | | | | If the function returns E_PENDING retry for a fixed number of times. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hevc: Bound check cu_qp_deltaLuca Barbato2014-01-21
| | | | | The T-REC-H.265-2013044 page 91 states it has to be in the range [-(26 + s->sps->qp_bd_offset / 2), (25 + s->sps->qp_bd_offset / 2)].
* hevc: Bound check slice_qpLuca Barbato2014-01-21
| | | | | | | | | The T-REC-H.265-2013044 page 79 states it has to be in the range [-s->sps->qp_bd_offset, 51]. Sample-Id: 00001386-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* hevc: Prevent some integer overflowsLuca Barbato2014-01-21
| | | | | | | | get_ue_golomb_long() returns an unsigned. Sample-Id: 00001541-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* hevc: Remove useless clipGuillaume Martres2014-01-21
| | | | | | | | | | The src buffer should only contain values in the interval [0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in the interval [0, 31], so no clip is needed. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hevc: clip pixels when transquant bypass is usedGuillaume Martres2014-01-21
| | | | | | | | | | | | The reconstructed picture should always be clipped (see section 8.6.5), previously we did not clip coding units where cu_transquant_bypass_flag == 1. Sample-Id: 00001325-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hevc: Use uint64 to check for tile dimensionsLuca Barbato2014-01-21
| | | | | | | | | | And use unsigned datatypes. Otherwise it would overflow. Sample-Id: 00001315-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* hevc: Fix modulo operationsMichael Niedermayer2014-01-21
| | | | | | | Keep qp fields within the range. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hevc: check that VPS referenced from SPS existsMichael Niedermayer2014-01-21
| | | | | | | | This matches how its done for SPS/PPS. Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vc1: Always reset numref when parsing a new frame header.Michael Niedermayer2014-01-20
| | | | | | | | | Fixes an issue where the B-frame coding mode switches from interlaced fields to interlaced frames, causing incorrect decisions in the motion compensation code and resulting in visual artifacts. CC: libav-stable@libav.org Signed-off-by: Tim Walker <tdskywalker@gmail.com>
* rtmpproto: Send a full, absolute timestamp if it isn't monotonically growingMartin Storsjö2014-01-20
| | | | | | | | The normal differential timestamps can't handle negative differences, thus send a full packet header with an absolute timestamp in these cases. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Avoid using uninitialized memoryMartin Storsjö2014-01-20
| | | | | | | If the url ends with .flv, we stripped it but didn't initialize rt->playpath, doing av_strlcat on an uninitialized buffer. Signed-off-by: Martin Storsjö <martin@martin.st>
* mov: do not set avg_frame_rate in the demuxerJustin Ruggles2014-01-20
| | | | | | | | | | | The track duration is often not reliable or is not the duration represented by the number of frames. In those cases, avg_frame_rate was reported incorrectly. Removing this code falls back to the default calculation in avformat_find_stream_info(). This is a partial revert of commit c3aeaa540. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* lavc: deprecate CODEC_FLAG_EMU_EDGE and avcodec_get_edge_width().Anton Khirnov2014-01-20
|
* mpegvideo: allocate edges when encoding.Anton Khirnov2014-01-20
| | | | | Allocating edges will be removed from generic code, so the encoder must handle this explicitly.
* lavc: allow the caller to override dimensions in ff_get_buffer()Anton Khirnov2014-01-20
| | | | This will be useful for allocating edges in the encoders.
* eac3: cosmetics, re-indent.Tim Walker2014-01-19
|
* (e)ac3: clip surround mix level indexes.Tim Walker2014-01-19
| | | | Values 0-2 are reserved, 3 (-1.5dB) should be used instead.

|
* ac3: set default matrix encoding modes in parse_frame_header.Tim Walker2014-01-19
| | | | Deduplicates some code.
* h264: check that an IDR NAL only contains I slicesAnton Khirnov2014-01-18
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: reset num_reorder_frames if it is invalidAnton Khirnov2014-01-18
| | | | | | | | | An invalid VUI is not considered a fatal error, so the SPS containing it may still be used. Leaving an invalid value of num_reorder_frames there can result in writing over the bounds of H264Context.delayed_pic. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: reset ref count if decoding the slice header failsAnton Khirnov2014-01-18
| | | | | | | | | Otherwise the ER code might try to use some already freed references. Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: prevent two matching fields from being both a short/long ref combinationAnton Khirnov2014-01-18
| | | | | | | Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: do not call field_end if we do not have a current pictureAnton Khirnov2014-01-18
| | | | | | | Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3Anton Khirnov2014-01-18
| | | | | | | | | | Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: reset first_field if frame_start() fails for missing refsAnton Khirnov2014-01-18
| | | | | | | | | | In this case we may not have a current frame, while first_field being set implies we do. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
