* mpegaudiodec: fix short_start calculationLuca Barbato2012-09-28
| | | | | | | The value should be always 3, as it follows from the specification. Fix a stack buffer overflow in exponents_from_scale_factors as reported by asan. Thanks to Dale Curtis for the sample vector.
* libopus: Remap channels using libopus' internal remapping.Nathan Caldwell2012-09-28
| | | | | | | | This way we can directly remap channels from Opus' channel order to libav's internal channel order, instead of mapping channels from Opus' order to Vorbis' order then to libav's order. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* xsub: feed init_get_bits the whole bufferAlexandre Colucci2012-09-25
| | | | | | | | | | | Do not use rlelen field for buffer size in init_get_bits, it is only the size of the data for the first field. Since it is not reliable, just use the size of the whole buffer. Additional comments add removal of unused rlelen variable by Reimar Döffinger. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* libfdk-aac: Allow setting VBR modes via a private optionMartin Storsjö2012-09-25
| | | | | | | | This avoids using the global_quality field and QSCALE flag for passing the VBR modes, since the value range of the global_quality field doesn't really map cleanly to this codec's VBR modes. Signed-off-by: Martin Storsjö <martin@martin.st>
* libfdk-aac: Warn the user that the VBR modes are unsupportedMartin Storsjö2012-09-25
| | | | | | | | | These modes were not originally exposed by the library at all. In practice, only a few of them work for each sample rate/profile combination, and they don't work at all for the more uncommon sample rates. Signed-off-by: Martin Storsjö <martin@martin.st>
* Revert "cbrt_tablegen: Include libm.h"Derek Buitenhuis2012-09-25
| | | | | | | This code runs on the host and should not use libm.h, which is meant for the target. This reverts commit 2768b717987d4e19d2774890d7d84aef531b1d9f.

* 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.

* 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

* 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.
