* mpeg: Split error resilience bits off into a separate fileDiego Biurrun2014-06-22

* Add av_image_check_sar() and use it to validate SARJustin Ruggles2014-06-20

* 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>

* h263dec: sanitize a condition.Anton Khirnov2013-11-27
| | | | | Call ff_mpeg4_decode_picture_header() only when the decoder has the MPEG4 codec id, not based on a vaguely related value of h263_pred.
* hwaccel: Simplify ff_find_hwaccelLuca Barbato2013-11-10

| | | | | | | | The actual usefulness of the hack is not known, and it does cause infinite loops with some broken input files. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* hwaccel: fix use with frame based multithreadingJanne Grunau2013-03-26
| | | | | | | | | | | | Allows use of AVHWAccel based decoders with frame based multithreading. The decoders will be forced into an non-concurrent mode by delaying ff_thread_finish_setup() calls after decoding of the current frame is finished. This wastes memory by unnecessarily using multiple threads and thus copies of the decoder context but allows seamless switching between hardware accelerated and frame threaded software decoding when the hardware decoder does not support the stream.
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08

* Add missing error_resilience includes to files that use ERDiego Biurrun2013-03-07
|
* lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecsRonald S. Bultje2013-03-06
| | | | | | | | | Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>

* mpeg4: support frame parameter changes with frame-mtJanne Grunau2012-09-19
| | | | | | | Adds a flag context_reinit to MpegEncContext to relieable keep track of frame parameter changes which require a context reinitialization. This is required for broken inputs which change the frame size but error out before the context can be reinitialized.
