* 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. Patch by S.N. Hemanth Meenakshisundaram $smeenaks$ucsd$edu$. Originally committed as revision 24731 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 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.

* Prefix value for flags with "0x", to make it clear that it is anStefano Sabatini2010-05-23

* Make config_props() show conversion information before to create theStefano Sabatini2010-05-07
| | | | | | | | | | swscale context. This makes eventual warnings issued in case of swscale context creation failure to be shown after the conversion information rather than before, which is slightly less confusing. Originally committed as revision 23056 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Log input size, input format and swscale flags used for conversion inStefano Sabatini2010-05-07

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30

* Avoid usage of avcodec_get_pix_fmt_name() andStefano Sabatini2010-01-31
| | | | | | | | | avcodec_get_chroma_sub_sample(), directly access av_pix_fmt_descriptors instead. Remove some of the dependancies of lavfi on lavc. Originally committed as revision 21575 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Add a slice_dir parameter to avfilter_draw_slice().Stefano Sabatini2009-12-04
| | | | | | | | | | Avoid the need to implement slice direction detection code, thus reducing code duplication. See the thread: "[FFmpeg-devel] [PATCH] Add a slice_dir parameter to avfilter_start_frame()". Originally committed as revision 20734 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use the correct chroma values for the data[] array used inStefano Sabatini2009-11-29
| | | | | | | | | | draw_slice(). The chroma values to use are supposed to be those of the input format, not that of the output format, the latter case was causing crashes and chroma issues. Originally committed as revision 20660 to svn://svn.ffmpeg.org/ffmpeg/trunk
