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
2010-03-07Show aspect ratio information in dprintf_picref() traces.Stefano Sabatini
Originally committed as revision 22255 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-25Add the graph2dot tools and document it.Stefano Sabatini
Also link avfiltergraph.o and graphparser.o against libavfilter, as it uses them. Originally committed as revision 22063 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-04Use pixel format descriptors for checking if the input format isStefano Sabatini
paletted. Simpler and more robust. Originally committed as revision 21631 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-02-01Use pixel format descriptors to check if the input format is paletted.Stefano Sabatini
Originally committed as revision 21597 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-31Avoid usage of avcodec_get_pix_fmt_name() andStefano Sabatini
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
2010-01-30Use av_get_pix_fmt() instead of the deprecated avcodec_get_pix_fmt()Stefano Sabatini
function. Originally committed as revision 21550 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-16Implement null video sink.Stefano Sabatini
Originally committed as revision 21242 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-16Implement null video source.Stefano Sabatini
Originally committed as revision 21240 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
2010-01-16Add symbol versioning for shared librariesMåns Rullgård
Based on patch by Reinhard Tartler <siretart tauware de> Originally committed as revision 21236 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-13Make avfilter_insert_filter() log the names of the filters betweenStefano Sabatini
which it inserts the new filter. Originally committed as revision 21177 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-13Make query_formats() print an error message if an auto-inserted scaleStefano Sabatini
filter cannot convert between input and output formats. Originally committed as revision 21176 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-10Make query_formats() increment the scaler_count after each scalerStefano Sabatini
insertion. Originally committed as revision 21124 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-10Make avfilter_insert_filter() print the instance name of theStefano Sabatini
auto-inserted scale filter, rather than the filter name, as this provides more information. Originally committed as revision 21123 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-10Add a log context to avfilter_graph_config_links().Stefano Sabatini
Originally committed as revision 21121 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-09 Make the scale filter set in the input and output links only theStefano Sabatini
respective pixel formats effectively supported by libswscale. Originally committed as revision 21105 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-08Fix compilation on gcc 2.95.3 (still supported) broken by r21077,Stefano Sabatini
which was due to declaring variable after code. Originally committed as revision 21086 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-08Make avfilter_formats_unref(AVFilterFormats **ref) handle the caseStefano Sabatini
when *ref is NULL. Originally committed as revision 21077 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-08Use the @return doxy command, and extend documentation for the returnStefano Sabatini
value of AVFilter.query_formats. Originally committed as revision 21076 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-08Avoid the use of the modal auxiliary "should" in theStefano Sabatini
AVFilter.query_formats doxy. The doxy expresses what a function does, not what it should do. Originally committed as revision 21075 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-08Fix doxy, use third person.Stefano Sabatini
Originally committed as revision 21073 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-06Change avfilter_add_colorspace() to make it accept **avff rather thanStefano Sabatini
*avff, so that an AVFilterFormats struct is created and returned by the function if *avff is NULL. Make the function use more convenient. Originally committed as revision 21035 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-04Make avfilter_all_colorspaces() add to the returned list of pixelStefano Sabatini
formats only the non-HW-accelerated formats, for which there is no sense in filtering. Originally committed as revision 21009 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-04Implement avfilter_add_colorspace().Stefano Sabatini
Originally committed as revision 21007 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-03Prefer "*FUNC_NAME(" over "* FUNC_NAME(" for XXX_configuration() andStefano Sabatini
XXX_license() functions, consistent with the rest of FFmpeg. Originally committed as revision 21005 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-11Make parse_filter() parsing more robust.Stefano Sabatini
Add ';' and '\n' to the terminating characters for the name of a filter, and ';' to the terminating characters for its args. Originally committed as revision 20800 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-09Make parse_key_value_pair() print an error message if a key is notStefano Sabatini
found in the context. Originally committed as revision 20779 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-09Use an unsigned int to contain all the color values of the expressionsStefano Sabatini
of the type 0xRRGBBAA parsed by av_parse_color(), using a simple int was resulting in unexpected results as the most significant bit was used for the sign. Originally committed as revision 20778 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-08Fix alpha plane flipping for the yuva420p and similar pixel formats.Stefano Sabatini
Originally committed as revision 20771 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-06Reindent after the last commit.Stefano Sabatini
Originally committed as revision 20755 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-06Fix slicify when the slice_direction is negative, make it send slicesStefano Sabatini
from the bottom to the top one. Originally committed as revision 20754 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
2009-11-29Use the correct chroma values for the data[] array used inStefano Sabatini
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
2009-11-29Use a valid log context for av_log().Stefano Sabatini
Originally committed as revision 20659 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-29Document slice ordering assumption required by avfilter_draw_slice().Stefano Sabatini
The assumption depends on the corresponding assumption done by sws_scale() and by the scale filter. Originally committed as revision 20655 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-26Remove AVFilter.next field, since it is not used and it is not goingStefano Sabatini
to be used since the implementation of the new filter registration system. Originally committed as revision 20611 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-25Implement avfilter_next().Stefano Sabatini
Originally committed as revision 20607 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-25Implement a new registration system for filters.Stefano Sabatini
Create a new static array containing pointers to the AVFilter definitions, so that the non-constant next filter in the AVFilter struct is not anymore required and the AVFilter definitions may be stored in shareable memory. Also change the signature for avfilter_register(), make it return an int since it may fail if there is not enough space in the static array for the registered filters. Originally committed as revision 20605 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-22Remove from the list of the supported formats the formats which areStefano Sabatini
not correctly supported. See the thread: "[FFmpeg-devel] [PATCH] Remove not truly supported formats support from the crop filter". Originally committed as revision 20576 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-18Add functions to return library license and library configuration.Diego Biurrun
Originally committed as revision 20547 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 20544 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-12Add scale filter.Stefano Sabatini
Originally committed as revision 20519 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-10Fix crop filter start_frame() for paletted formats different fromStefano Sabatini
PAL8. Shift data[1] only if the input format is not paletted. Originally committed as revision 20488 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-09Enable linking of parseutils.o.Stefano Sabatini
Originally committed as revision 20487 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-09Fix start_frame(), which was issuing chroma artifacts with planarStefano Sabatini

2009-11-04Vertical align.Stefano Sabatini
Originally committed as revision 20447 to svn://svn.ffmpeg.org/ffmpeg/trunk
