* libx264: change default to closed gop to match x264cliJohn Van Sickle2012-09-24
| | | | | | open-gop can be enabled with "-flags -cgop" Signed-off-by: Anton Khirnov <anton@khirnov.net>
* Use avcodec_free_frame() to free AVFrames.Anton Khirnov2012-09-24
|
* lavc: add avcodec_free_frame().Anton Khirnov2012-09-24
| | | | | Since an AVFrame now has malloced members (extended_data), it must have a destructor.
* lavc: ensure extended_data is set properly on decodingAnton Khirnov2012-09-24
|
* lavc: initialize AVFrame.extended_data in avcodec_get_frame_defaults()Anton Khirnov2012-09-24
|
* lavc: use av_mallocz to allocate AVFrames.Anton Khirnov2012-09-24
| | | | | Otherwise the frame is uninitialized, so avcodec_get_frame_defaults() cannot determine whether to free extended_data.
* lavc: rename the argument of avcodec_alloc_frame/get_frame_defaultsAnton Khirnov2012-09-24
| | | | | AVFrame is used for both audio and video, so calling the argument 'pic' is misleading.
* avcodec: fix memleak in avcodec_encode_audio2()Justin Ruggles2012-09-22
| | | | Ensure that padded_frame is freed before returning when needed.
* sipr: fall back to setting mode based on bit_rate.Reimar Döffinger2012-09-21
| | | | | | | | | | | | | | Not all applications (e.g. MPlayer) set block_align, and when using a different demuxer it might not even be easily available. So fall back to selecting mode based on bit rate as before if block_align has not useful value. It can't be worse than failing to decode completely.

* ARM: swap source operands in some add instructionsMans Rullgard2012-09-20
| | | | | | This allows using a 16-bit opcode when generating Thumb2 code. Signed-off-by: Mans Rullgard <mans@mansr.com>
* 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.

* libx264: add support for nal-hrd, required for Blu-ray streams.John Van Sickle2012-09-19

* tiffdec: Add support for GRAY16LE.Alex Converse2012-09-19
| | | | Tested with the GraphicsMagick TIFF archive and Libav generated files.
* tiffenc: Add support for little endian RGB48 and GRAY16Alex Converse2012-09-19

* 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.
* mpegvideo: check ff_find_unused_picture() return value for errorsJanne Grunau2012-09-19
|
* mpegvideo: release frame buffers before freeing themJanne Grunau2012-09-19
| | | | | Fixes triggering an assert in avcodec_default_release_buffer() introduced in 1b3439b30.
* rv34: use ff_MPV_common_frame_size_change()Janne Grunau2012-09-19
| | | | | Specialised functionality for size changes with the advantage of supporting frame size changes during frame-based multithreading.
* mpegvideo: add reinit function for frame parameter changesJanne Grunau2012-09-19
| | | | | | This is mainly required for frame parameter changes during frame based multithreading but single threaded usage profits too from avoiding ff_MPV_common_end()/ff_MPV_common_init() cycles.
* mpegvideo: move frame size dependent memory management to separate functionsJanne Grunau2012-09-19
| | | | | This is a preparation for supporting frame size changes during frame-based multithreading.
* avcodec: cleanup utils.cLuca Barbato2012-09-18

* binkaudio: remove unneeded GET_BITS_SAFE macroJustin Ruggles2012-09-18
| | | | Normal get_bits() already has overread protection.
* binkaudio: use float sample formatJustin Ruggles2012-09-18
| | | | Use planar for DCT codec, interleaved for RDFT codec.
* binkaudio: use a different value for the coefficient scale for the DCT codecJustin Ruggles2012-09-18
| | | | Eliminates the need for vector_fmul_scalar() in each frame.

* lavc: replace AVCodecContext.encode with subtitle-specific callbackAnton Khirnov2012-09-17
| | | | | AVCodecContext.encode is currently used only for subtitles, encode2 is used for audio and video.
* lavc: add const to private codec class initialization.Anton Khirnov2012-09-17
| | | | Silences a warning about discarding const.
* 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>
* nellymoserdec: drop support for s16 output.Anton Khirnov2012-09-16
| | | | | It internally decodes as float and then converts to s16 by a call to float_to_int16(). The caller can do this just as well by using lavr.
* bmpdec: only initialize palette for pal8.Anton Khirnov2012-09-16
| | | | | | | | | Gray8 is not considered to be paletted, so this would cause an invalid write. Fixes bug 367. CC: libav-stable@libav.org

* vorbisdec: ensure FASTDIV denominator is never 1Luca Barbato2012-09-14
| | | | | | | | | | In both usages of FASTDIV the denominator might be 1. Using a branch could make the function slower than using a normal division. Both denominator and numerator can be multiplied by 2 safely and using shifts is faster than using a branch.
