* mpeg1: Make intra-block decoding independent of MpegEncContextVittorio Giovara2016-02-09
| | | | | | | This allows untangling the eatqi decoder from the MPEG-1 decoder. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>
* mpeg12dec: Refactor mpeg1_decode_block_intra()Diego Biurrun2016-02-09
| | | | | Reduce variable scope, improve variable name, drop pointless ff_dlog(), merge variable declaration and initialization, whitespace cosmetics.
* mpeg12dec: Always close reader on errorVittorio Giovara2016-02-09
| | | | | | | A reader left open may lead to hangs. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavc: add profiles to AVCodecDescriptorAnton Khirnov2015-12-12
| | | | | The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.

| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mpegvideo: Drop flags and flags2Vittorio Giovara2015-05-22
| | | | They are just duplicates of AVCodecContext members so use those instead.

* 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.

* idct: remove call to ff_idctdsp_init from ff_MPV_common_initJohn Stebbins2014-08-14
| | | | | One step in untangling the mpegvideo code and fixing some problems in the order that initialization is being done in h263dec and h261dec.

* lavc: set AVCodecContext.hwaccel in ff_get_format()Anton Khirnov2014-05-11
| | | | This way each decoder does not have to do the same thing manually.
* lavc: Add an internal wrapper around get_format()Anton Khirnov2014-05-11
| | | | It will be useful in the following commits.
* mpegvideo: operate with pointers to AVFrames instead of whole structswm42014-04-09
| | | | | | | | | | | | | The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* mpeg12dec: do not add stereo3D side data to a non-existing frameJanne Grunau2014-02-13
| | | | | | | | | User data is usually coded before slice data. That means the frame the user data belongs to is not available while parsing the user data. The stereo3D side data has to use the same indirection over the private context as pan scan information and A53 captions. Bug-Id:632
* mpeg: K&R formatting cosmeticsVittorio Giovara2014-02-04

* mpeg12: check scantable indices in all decode_block functionsJanne Grunau2014-01-25
| | | | | | | | | Add checks to the fast functions used with CODEC_FLAGS2_FAST and move the check for all other functions to before the invalid memory is accessed. Fixes https://trac.videolan.org/vlc/ticket/9713 with CODEC_FLAGS2_FAST. CC: libav-stable@libav.org

* Deprecate obsolete XvMC hardware decoding supportDiego Biurrun2013-11-13
| | | | | | | XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.
* hwaccel: Simplify ff_find_hwaccelLuca Barbato2013-11-10
| | | | It is always called by passing fields from an AVCodecContext.
* mpeg12dec: stop using deprecated avcodec_set_dimensionsAnton Khirnov2013-10-31

* mpeg12: Ignore slice threading if hwaccel is activeRémi Denis-Courmont2013-07-25
| | | | | | | Slice threading does not work with hardware acceleration, as decoding is per-picture. This fixes Bugzilla #542. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* mpeg12: skip frames consistentlyJanne Grunau2013-05-28
| | | | | | | The decoder did not start predicted frames with missing references but called the end of frame handling on them anyway. This caused an assertion in the VA API HW accelorator since it tried to render a picture with uninitialized buffers.
