* lavc: AV-prefix all codec flagsVittorio Giovara2015-07-27
| | | | | | Convert doxygen to multiline and express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavc: Deprecate avctx.me_methodVittorio Giovara2015-07-27
| | | | | | | | This option is extremely codec specific and only a few codecs employ it. Move it to codec private options instead: mpegenc family supports only 3 values, xavs and x264 use 5, and xvid has a different metric entirely. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* mpegvideo: Move MotionEstContext and function declarations to a separate headerVittorio Giovara2015-05-31
|
* mpegvideo: Drop flags and flags2Vittorio Giovara2015-05-22
| | | | They are just duplicates of AVCodecContext members so use those instead.
* motion_est: Fix warning from zero_cmp() assignmentVittorio Giovara2015-04-19
| | | | | | | | warning: incompatible pointer types assigning to 'me_cmp_func' (aka 'int (*)(struct MpegEncContext *, uint8_t *, uint8_t *, ptrdiff_t, int)') from 'int (MpegEncContext *, uint8_t *, uint8_t *, int, int)' [-Wincompatible-pointer-types]

* motion_est: remove dead codeVittorio Giovara2014-11-03
| | | | | | mb_type is initialized to 0 and never updated before the check. Bug-Id: CID 1238782

* lavc: move CODEC_FLAG_MV0 to mpegvideoAnton Khirnov2014-05-01
|
* 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>
* dsputil: Use correct type in me_cmp_func function pointerDiego Biurrun2014-03-20

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

* avcodec: Drop unnecessary ff_ name prefixes from static functionsDiego Biurrun2013-04-30
|
* 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>
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08
|
* mpegvideo_enc: drop support for reusing the input motion vectors.Anton Khirnov2013-03-08
| | | | | | This misfeature is most likely completely useless and conflicts with removing the mpegvideo-specific fields from AVFrame. In the improbable case it is actually useful, it should be reimplemented in a better way.
* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-26
|
* dsputil: Move get_penalty_factor() to the only place it is used.Diego Biurrun2013-02-07
|
* Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter.Diego Biurrun2013-02-05
| | | | | This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.
* mpegvideo: remove some unused variables from Picture.Anton Khirnov2013-01-29
|
* Drop Snow codecDiego Biurrun2013-01-06
| | | | Snow is a toy codec with no real-world use and horrible code.
* Move avutil tables only used in libavcodec to libavcodec.Diego Biurrun2012-10-11

* avcodec: Convert some commented-out printf/av_log instances to av_dlogDiego Biurrun2012-10-01

* avcodec: Drop silly and/or broken printf debug outputDiego Biurrun2012-10-01

* motion_est: fix use of inline on extern functionsMans Rullgard2012-09-20
| | | | | | | | | | | | | | | | | | Inline functions declared without extern do not provide an external definition in standard C99. This code only works because most compilers do not implement the inline semantics correctly. With a stricter compiler, linking fails with unresolved references to these functions. Declaring the functions extern inline works correctly with some compilers while some others still fail to create external definitions. For maximum portability, create a static inline version with an externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search is so large that no sane compiler inlines it anyway, so there the inline keyword can simply be dropped with no effect.

* motion_est: drop inline from sad_hpel_motion_search()Mans Rullgard2012-08-09
| | | | | | | This function is only ever called through a function pointer, so marking it inline makes no sense. Signed-off-by: Mans Rullgard <mans@mansr.com>

* motion_est: remove useless no_motion_search() functionMans Rullgard2012-08-09
| | | | | | | | At both places this function is called, mb_[xy] == s->mb_[xy] making the call together with following code equivalent to simply assigning zeros. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Replace memset(0) by zero initializations.Diego Biurrun2012-03-28

* motion_est: make MotionExtContext.map_generation unsignedMans Rullgard2011-10-11
| | | | | | | | The way this value is used, it should be an unsigned type. While the numerical value has no meaning, unsigned wraparound is relied upon. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Eliminate FF_COMMON_FRAME macro.Diego Biurrun2011-07-11
| | | | | FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
