* avfilter: pool draining and self destruction support.Michael Niedermayer2012-01-12
| | | | | | This should fix a memleak. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* lavfi: fix avfilter_default_get_audio_buffer() after changes in ↵Stefano Sabatini2011-12-27
| | | | | | | | | | | | | | | av_samples_alloc() av_samples_alloc() behavior changed in bbb46f3ec, resulting in random data filling the data[] and linesize[] arrays of the returned AVFilterBufferRef, which was resulting in wrong behavior in case of code checking on data[i] nullity. In particular fixes crash in avfilter_filter_samples(): for (i = 0; samplesref->data[i]; i++) memcpy(link->cur_buf->data[i], samplesref->data[i], samplesref->linesize[0]); and correctly fills the linesize[] array for planar data.

| * Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample().Justin Ruggles2011-06-20
| | | | | | | | av_get_bits_per_sample_fmt() is deprecated.
| * Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | | | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
| * Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | | | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* | lavfi: rename avfilter_all_* function names to avfilter_make_all_*Stefano Sabatini2011-09-16
| | | | | | | | | | | | | | | | | | | | A function name should tell what the function does rather than what the function returns. This also avoids possible conflicts (e.g. between a function and a public list of all supported formats), and clarifies the code. Breaks audio API/ABI, add a backward compatibility layer for video API/ABI.
* | lavfi: simplify signature for avfilter_get_audio_buffer() and friendsStefano Sabatini2011-09-12
| | | | | | | | | | | | | | | | | | | | | | The additional parameters were never used and are complicating the function interface. Also, they were inconsistent with the way the video API works. So this assumes that a requested samples buffer will have *always* the format specified in the requested link. This breaks audio filtering API and ABI.
* | lavfi: avoid void* arithmetic in defaults.c:set_common_formats()Stefano Sabatini2011-08-06
| | | | | | | | | | | | | | | | | | void* pointer arithmetic semantics is undefined, use uint8_t* instead. Also fix GCC warnings: defaults.c: In function ‘set_common_formats’: defaults.c:184: warning: pointer of type ‘void *’ used in arithmetic defaults.c:189: warning: pointer of type ‘void *’ used in arithmetic
* | lavfi: remove default config_props() callback and refactor ↵Mina Nagy Zaki2011-08-06
| | | | | | | | | | | | | | | | | | | | | | | | avfilter_config_links() Link properties have to be checked after config_props() is called to make sure everything is sane, so the default config_props() for output links was redundant. Also remove channel_layout check as it is now negotiated. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>

| | | | | | | | | | Use avfilter_get_audio_buffer_ref_from_arrays() in avfilter_default_get_audio_buffer(), simplify.
* | lavfi: use av_samples_alloc() in avfilter_default_get_audio_buffer()Stefano Sabatini2011-06-06

* | lavfi: prefer nb_samples over size in AVFilterBufferRefAudioPropsStefano Sabatini2011-06-06
| | | | | | | | | | | | | | | | | | Remove AVFilterBufferRefAudioProps.size, and use nb_samples in avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in place of size. This is required as the size in the audio buffer may be aligned, so it may not contain a well defined number of samples.
