* vsrc_buffer: allow buffering arbitrary number of frames.Anton Khirnov2012-04-01
|
* vf_scale: avoid a pointless memcpy in no-op conversion.Anton Khirnov2012-04-01
| | | | I.e. just pass the buffer along when src parameters == dst parameters.
* avfiltergraph: try to reduce format conversions in filters.Anton Khirnov2012-04-01
| | | | | | | | | | | | | Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)
* avfiltergraph: add an AVClass to AVFilterGraph on next major bump.Anton Khirnov2012-04-01
| | | | It will be used for logging, possibly also AVOptions.
* build: Only clean the architecture subdirectory we build for.Diego Biurrun2012-03-26
| | | | | This allows simplifying the Makefiles; it is no longer necessary to register arch subdirectory Makefiles, just putting them in place is enough.
* Mark mutable static data const where appropriate.Alex Converse2012-02-21
|
* Drop some completely unnecessary av_unused attributes.Diego Biurrun2012-02-13
|
* yadif: specify array size outside DECLARE_ALIGNEDJanne Grunau2012-02-09
|
* cosmetics: Delete empty lines at end of file.Diego Biurrun2012-02-09
|
* pixdesc: mark pseudopaletted formats with a special flag.Anton Khirnov2012-02-08
| | | | | | This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().
* drawtext: add 'fix_bounds' option on coords fixingAndrey Utkin2012-02-06
| | | | | | | | | | Before, drawtext filter deliberately altered given text coordinates if text didn't fully fit on the picture. This breaks the use case of scrolling large text, e.g. movie closing credits. Add 'fix_bounds', to make it usable in such cases (by setting its value to 0). Default behavior is not changed, and non-fitting text coords are fixed. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* drawtext: fix text_{w, h} expression varsAndrey Utkin2012-02-06
| | | | | | Before, {text_,}{w,h} vars hadn't got initialized Signed-off-by: Anton Khirnov <anton@khirnov.net>
* drawtext: add missing braces around an if() block.Andrey Utkin2012-02-05
| | | | | | Prevents uninitialized read. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* cosmetics: Remove some unnecessary block braces.Diego Biurrun2012-01-25
|
* cosmetics: Move static and inline attributes to more standard places.Diego Biurrun2012-01-14
| | | | Fixes several "‘static’ is not at beginning of declaration" warnings.

* Add minor bumps and APIchanges entries for lavc/lavfi changes.Anton Khirnov2011-12-25
|
* lavfi: add a new function av_buffersrc_buffer().Anton Khirnov2011-12-25
| | | | | It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a memcpy.
* lavfi: add avfilter_copy_frame_props()Stefano Sabatini2011-12-25
| | | | | avfilter_copy_frame_props() avoids code duplication and increases robustness.
* lavc: add a sample_aspect_ratio field to AVFrameStefano Sabatini2011-12-25
| | | | | | | The sample aspect ratio is a per-frame property, so it makes sense to define it in AVFrame rather than in the codec/stream context. Simplify application-level sample aspect ratio information extraction, and allow further simplifications.
* allfilters: fix type of avfilter_vsrc_buffer.Anton Khirnov2011-12-23
|
* lavfi: always build vsrc_buffer.Anton Khirnov2011-12-22
| | | | It's a part of public API.

* Replace all uses of av_close_input_file() with avformat_close_input().Anton Khirnov2011-12-12
|
* lavfi: install libavfilter/vsrc_buffer.hAndrey Utkin2011-12-11
| | | | | | It declares API necessary for filtering apps. Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* drawtext: make x and y parametricLuca Barbato2011-12-03
| | | | | | Introduce variables "E", "PHI", "PI", "main_w"/"W", "main_h"/"H", "text_w"/"w", "text_h"/"h", "x", "y", "n" and "t" in line with vf_overlay and refactor the code accordingly.
* drawtext: manage memory allocation betterLuca Barbato2011-12-03
| | | | | Call dtext_prepare_text as early as possible Do not draw if the memory allocation failed
* drawtext: refactor draw_textLuca Barbato2011-12-03
| | | | Split the memory allocation from the actual drawing.
* Make channel layout masks unsignedMans Rullgard2011-11-25
| | | | | | | | | | It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>
