2010-05-07Try to keep track of interlaced and top field first.Michael Niedermayer
Originally committed as revision 23044 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-19Create a set of null callback functions.Bobby Bingham
These are useful for filters which don't modify the image data. Originally committed as revision 22594 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-13Add AVFilterPicRef.pos field and make libavfilter propagate streamStefano Sabatini
byte position information, as stored in the pkt.pos, through the filterchain. Note that the pos field is added *non* at the end of the AVFilterPicRef struct, thus breaking ABI compatibility, which is allowed as the API is still considered non-stable. Originally committed as revision 22506 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-08avfilter: make avfilter_default_free_video_buffer() staticMåns Rullgård
This function is not referenced outside this file and has no prototype. Feel free to flame if this is wrong. Originally committed as revision 22314 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-08Make avfilter_default_start_frame() correctly pass the aspect ratioStefano Sabatini
information to the next filter. Originally committed as revision 22300 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-16Make avfilter_default_start_frame() request a buffer with the sameStefano Sabatini
size of the output link of the destination filter, rather than of the size of the input link. In particular this fixes a crash in the rotate filter. Originally committed as revision 21238 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-05Add a slice_dir parameter to avfilter_draw_slice().Stefano Sabatini
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
2009-10-18Make avfilter_get_video_buffer() recursive.Stefano Sabatini
When called on a link with a filter whose destination pad has not a get_video_buffer callback defined, it will call avfilter_get_video_buffer() on the first output link of the destination filer, rather than use avfilter_default_get_buffer(), so the video buffer can be allocated forward in the filterchain. Also add the w and h parameters to avfilter_get_video_buffer(), as the minimum width and height requested by each filter in the filterchain may change, this allows for example a memcpy-less pad filter. This change breaks API / ABI backward compatibility. See the thread: "[PATCH] Implement recusive avfilter_get_video_buffer()". Originally committed as revision 20272 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-10-07Add w and h fields to AVFilterPic.Stefano Sabatini
See the thread: "[FFmpeg-devel] [PATCH] Add w,h fields to AVFilterPic". Originally committed as revision 20189 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-23Move ALIGN macro to libavutil/common.h and use it in various placesDavid Conrad
Originally committed as revision 18898 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-01-12Implement the avfilter_default_draw_slice() handler and use it inStefano Sabatini
avfilter_draw_slice() when the draw_slice callback is not defined in the input pad. Originally committed as revision 16554 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-02-16Rework link property configuration system.Vitor Sessak
This can now handle filters which are added to graphs out of order, including auto-inserted scale filters. As an added bonus, it can now detect circular filter chains which wouldn't work anyway. Commited in SoC by Bobby Bingham on 2007-12-24 03:22:10 Originally committed as revision 12073 to svn://svn.ffmpeg.org/ffmpeg/trunk

they're useless for outputting. Commited in SoC by Bobby Bingham on 2007-08-17 22:52:18 Originally committed as revision 12070 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-02-16Track the permissions that have been given out to each picture.Vitor Sessak
This should make it easier to know what can be done to a buffer once it's been passed to your filter without falling back to copying it "just to be safe". Commited in SoC by Bobby Bingham on 2007-08-17 18:21:07 Originally committed as revision 12068 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-02-16Move default entry point implementations to their own file.Vitor Sessak
