* mpegvideo: Drop flags and flags2Vittorio Giovara2015-05-22
| | | | They are just duplicates of AVCodecContext members so use those instead.

* 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>
* mpegvideo: move mpegvideo formats-related defines to mpegutils.hVittorio Giovara2014-03-16

* Update dsputil- and SIMD-related comments to match reality more closelyDiego Biurrun2014-03-13
|
* mpegvideo: drop support for real (non-emulated) edgesAnton Khirnov2014-01-09
| | | | | | | Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.
* lavc: Edge emulation with dst/src linesizeRonald S. Bultje2013-11-15
| | | | | | Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.

* mpegvideo: Avoid 32-bit wrapping of linesize multiplicationsMartin Storsjö2013-09-04
| | | | | | | | | This makes sure that linesize * start_y doesn't overflow, so that emulated_edge_mc can get back the original value if needed. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* mpegvideo: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje2013-04-19
| | | | | | This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>

* dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun2013-02-08
|
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mpegvideo: simplify dxy calculation in hpel_motion()Mans Rullgard2012-11-23

* h263: avoid memcpys over array bound in motion vector caching for obmcJanne Grunau2012-10-26
| | | | Fixes CID602232.
* mpegvideo: drop unnecessary arguments to hpel_motion()Mans Rullgard2012-09-16
| | | | | | | These arguments are either constants or copies of MpegEncContext fields just as easily accessed within the function. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegvideo: drop 'inline' from some functionsMans Rullgard2012-09-16
| | | | | | | These functions do not benefit from being inlined. They are large, and there are no opportunities for constant propagation. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegvideo: reduce excessive inlining of mpeg_motion()Mans Rullgard2012-08-09
| | | | | | | | | The main benefit of inlining this function is from constant propagation for the 'field_based' argument. Instead of inlining all calls, create two versions of the function for field_based values of 0 and 1. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegvideo: convert mpegvideo_common.h to a .c fileMans Rullgard2012-08-09
This file defines a single, huge function, MPV_motion(), which although being declared inline is not actually inlined by the compiler (for good reason). There is thus no sense in defining this function in a header file, resulting in multiple copies of it in the final library. Signed-off-by: Mans Rullgard <mans@mansr.com>
