* vf_scale: make the dar variable return the DAR.Rudolf Polzer2013-11-02
| | | | | | | | | Before, it just returned width/height. Correct is width/height*sar. That way it is consistent with DAR as in probe output and setdar. Signed-off-by: Rudolf Polzer <divverent@xonotic.org> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: do not export the filters from shared objectsAnton Khirnov2013-10-28

* vf_scale: switch to an AVOptions-based system.Anton Khirnov2013-04-09
|
* lavfi: switch to AVFrame.Anton Khirnov2013-03-08
| | | | | Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.
* lavfi: merge start_frame/draw_slice/end_frameAnton Khirnov2012-11-28
| | | | | Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.
* lavfi: do not use av_pix_fmt_descriptors directly.Anton Khirnov2012-10-12
|
* lavfi: convert input/ouput list compound literals to named objectsMans Rullgard2012-10-10
| | | | | | | A number of compilers, for example those from TI and IBM, choke on these initialisers. The current style is also quite ugly. Signed-off-by: Mans Rullgard <mans@mansr.com>

|
* lavfi: remove 'opaque' parameter from AVFilter.init()Anton Khirnov2012-06-26
| | | | | | It is not used in any filters currently and is inherently evil. If passing binary data to filters is required in the future, it should be done with some AVOptions-based system.
* lavfi: make AVFilterPad opaque after two major bumps.Anton Khirnov2012-06-13
| | | | It will allow adding new fields to it without ABI breaks.
* lavfi: make avfilter_get_video_buffer() private on next bump.Anton Khirnov2012-06-13
| | | | | They are only useful inside filters and we don't allow user filters for now.

* 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.

* Separate video specific BufferRef properties into VideoProps.S.N. Hemanth Meenakshisundaram2010-08-11
| | | | | | | | | | | | Define a new struct AVFilterBufferRefVideoProps and add a type field to AVFilterBufferRef. Video specific properties in AVFilterBufferRefVideoProps are now referred to by *video pointer in AVFilterBufferRef. Patch by S.N. Hemanth Meenakshisundaram smeenaks->ucsd.edu. Originally committed as revision 24763 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename fields:S.N. Hemanth Meenakshisundaram2010-08-07
| | | | | | | | | | | | | | AVFilterLink.srcpic -> AVFilterLink.src_buf AVFilterLink.cur_pic -> AVFilterLink.cur_buf AVFilterLink.outpic -> AVFilterLink.out_buf The new names are more generic and more consistent, since the struct they contain, which was named AVFilterPicRef, has been renamed to AVFilterBufferRef. Patch by S.N. Hemanth Meenakshisundaram %smeenaks%ucsd%edu%. Originally committed as revision 24732 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename functions and fields:S.N. Hemanth Meenakshisundaram2010-08-07
| | | | | | | | | | | | avfilter_(un)ref_pic -> avfilter_(un)ref_buffer avfilter_copy_picref_props -> avfilter_copy_buffer_ref_props AVFilterBufferRef.pic -> AVFilterBufferRef.buffer They have been renamed to allow sharing with audio.

* Rename AVFilterPicRef to AVFilterBufferRef.S.N. Hemanth Meenakshisundaram2010-08-07
| | | | | | | | | The struct is going to be used for storing audio buffer references as well, and the new name is more generic. Patch by S.N. Hemanth Meenakshisundaram @smeenaks@ucsd@edu@. Originally committed as revision 24730 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Generalize pixel format enum fields to int formats.S.N. Hemanth Meenakshisundaram2010-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to make the libavfilter framework work with audio filters. In particular add a type field to AVFilterLink, change the field types: enum PixelFormat format -> int format in AVFilterBuffer enum PixelFormat *formats -> int *formats in AVFilterFormats enum PixelFormat *format -> int format in AVFilterLink and change the function signatures: AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); -> AVFilterFormats *avfilter_make_format_list(const int *fmts); int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); -> int avfilter_add_format(AVFilterFormats **avff, int fmt); AVFilterFormats *avfilter_all_colorspaces(void); -> AVFilterFormats *avfilter_all_formats(enum AVMediaType type); This change breaks libavfilter API/ABI.
