* h264: initialize H264Context.avctx in init_thread_copyAnton Khirnov2015-02-21
| | | | | This prevents using a wrong (first thread's) AVCodecContext if decoding a frame in the first pass over all threads fails.
* h264: Do not share rbsp_buffer across threadsMichael Niedermayer2015-01-28

* h264: drop any pretense of support for data partitioningAnton Khirnov2015-01-27
| | | | | | | | | | It does not work correctly and apparently never did. There is no indication that this (mis)feature is ever used in the wild or even that any software other than the reference supports it. Since the code that attempts to support it adds some nontrivial complexity and has resulted in several bugs in the past, it is better to just drop it.
* h264: do not reset the ref lists in flush_change()Anton Khirnov2015-01-27
| | | | | They are always constructed anew when needed, so there is no need to reset them explicitly.
* h264: move parser-only variables to their own contextAnton Khirnov2015-01-27
|
* error_resilience: move the MECmpContext initialization into ER codeAnton Khirnov2015-01-27
| | | | | | | Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.
* h264: simplify code in flush_dpb()Anton Khirnov2015-01-27
| | | | | There is no point in clearing reference explicitly, since that will be done as a part of ff_h264_unref_picture() right below.
* h264: restore a block mistakenly removed in e10fd08aAnton Khirnov2014-12-27
| | | | | CC: libav-stable@libav.org Bug-ID: 781

* lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.
* h264: reset ret to avoid propagating minor failuresMichael Niedermayer2014-09-29
| | | | | | | | Unbreak 772d150a6e82542c06b0c251e73dd299d98d1027. CC: libav-stable@libav.org Bug-Id: 750 / 905753 Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* h264: move relevant fields from Picture to H264PictureVittorio Giovara2014-03-16
|
* er: move relevant fields from Picture to ERPictureVittorio Giovara2014-03-16
| | | | | | | This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().
* h264: directly use frames in ff_h264_draw_horiz_band()Vittorio Giovara2014-03-16

* Give IDCT matrix transpose macro a more descriptive nameDiego Biurrun2014-02-27

* h264: make context_count unsignedJanne Grunau2014-02-12
| | | | | Removes the bogus but scary looking warning 'libavcodec/h264.c:4529:49: warning: array subscript is below array bounds [-Warray-bounds]'.
* h264: reset data partitioning at the beginning of each decode callAnton Khirnov2014-02-04
| | | | | | | | | Prevents using GetBitContexts with data from previous calls. Fixes access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* avutil: remove timer.h include from internal.hJanne Grunau2014-01-25
| | | | Added libavutil/timer.h include to all files with {START,STOP}_TIMER.
* h264: skip chroma edges at the picture boundary while deblocking 4:4:4Janne Grunau2014-01-22
| | | | | | | | | This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams. The Spec explicitly states that the deblocking filter is not applied to edges at the boundary of the picture. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* h264: check that an IDR NAL only contains I slicesAnton Khirnov2014-01-18

* 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: 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
* h264: check that execute_decode_slices() is not called too many timesAnton Khirnov2014-01-06
| | | | | | | Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: reject mismatching luma/chroma bit depths during sps parsingAnton Khirnov2014-01-06
| | | | | | | | | | There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: rebuild the default ref list if the reference count changesAnton Khirnov2014-01-06
