* lavfi: better channel layout negotiationJustin Ruggles2012-07-27
| | | | | | | Allow substitution of channel pairs in the input for nearby channel pairs in the output in order to get a closer match. Also weigh LFE channel mismatch differently to favor matching the same layout without LFE over one less channel with LFE.
* vf_yadif: unset cur_buf on the input link.Anton Khirnov2012-07-26
| | | | | | | The buffer is stored internally, so this prevents it from being unreffed automatically. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vf_overlay: ensure the overlay frame does not get leaked.Anton Khirnov2012-07-26
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* avfilter: Fix printf format string conversion specifierDiego Biurrun2012-07-25
| | | | libavfilter/avfilter.c:224:9: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 5 has type ‘int’ [-Wformat]
* lavfi: place x86 inline assembly under HAVE_INLINE_ASM.Ronald S. Bultje2012-07-22
| | | | | This allows compiling this code using compilers that do not understand gcc-style inline assembly.
* buffersrc: check ff_get_audio_buffer() for errors.Anton Khirnov2012-07-22

* lavfi: check all ff_get_video_buffer() calls for errors.Anton Khirnov2012-07-22

|
* buffersrc: avoid creating unnecessary buffer referenceAnton Khirnov2012-07-22

* yadif: use emms_c() instead of inline assembly for emms invocations.Ronald S. Bultje2012-07-21
|
* lavfi: use const for AVFilterPad declarations in all filters.Ronald S. Bultje2012-07-21
|
* lavfi: unref AVFilterLink.out_buf in ff_end_frame().Anton Khirnov2012-07-20
| | | | | This reduces code duplication and prevents stale pointers from remaining on the link.
* lavfi: unref AVFilterLink.cur_buf in ff_end_frame().Anton Khirnov2012-07-20
| | | | | This reduces code duplication and prevents stale pointers from remaining on the link.
* vsrc_testsrc: avoid an unnecessary avfilter_ref_buffer().Anton Khirnov2012-07-20
|
* vf_slicify: clear AVFilterLink.cur_buf in start_frame().Anton Khirnov2012-07-20
| | | | | The buffer is passed on to the next filter, so we shouldn't keep any pointers to it.
* vf_settb: simplify start_frame().Anton Khirnov2012-07-20
| | | | | Avoid pointless filter ref/unref. Just use the reference passed to start_frame().
* vf_fieldorder: don't give up its own reference to the output buffer.Anton Khirnov2012-07-20
|
* vf_pad: don't give up its own reference to the output buffer.Anton Khirnov2012-07-20
|
* vf_overlay: don't access a buffer reference that's been given away.Anton Khirnov2012-07-20
|
* vf_drawtext: don't give up its own reference to the input buffer.Anton Khirnov2012-07-20
| | | | | | Directly forwarding the input buffer to the next filter means that drawtext no longer owns any references to it and thus shouldn't refer to it in any way.
* vf_gradfun: don't store two pointers to one AVFilterBufferRef.Anton Khirnov2012-07-20
|
* vf_delogo: don't store two pointers to one AVFilterBufferRef.Anton Khirnov2012-07-20
|
* vf_aspect: clear AVFilterLink.cur_buf in start_frame().Anton Khirnov2012-07-20
| | | | | The buffer is passed on to the next filter, so we shouldn't keep any pointers to it.

* af_resample: fix request_frame() behavior.Anton Khirnov2012-07-09
| | | | | Make sure that an output frame has really been produced before returning 0.
* af_asyncts: fix request_frame() behavior.Anton Khirnov2012-07-09
| | | | | Make sure that an output frame has really been produced before returning 0.
* lavr: Use AV_SAMPLE_FMT_NONE to auto-select the internal sample formatJustin Ruggles2012-07-08
| | | | Also make this the default value.
* af_amix: avoid spurious EAGAIN.Anton Khirnov2012-07-06
| | | | | | | | | | Input on/off state can change in request_samples(), which can result in a state where only the first input is active. get_available_samples() will then return 0, and request_frame() will fail with EAGAIN even though there is data on the single active input. Take this into account and check the number of active inputs again after calling request_samples().
* af_amix: return AVERROR(EAGAIN) when request_frame didn't produce output.Anton Khirnov2012-07-06
| | | | 0 should only be returned when there was at least one output frame.
* af_amix: only consider negative return codes as errors.Anton Khirnov2012-07-06
