2011-04-26lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enumsStefano Sabatini
Also deprecate av_get_pict_type_char() in favor of av_get_picture_type_char(). The new enum and av_get_picture_type_char() are defined in libavutil. This allows the use in libavfilter without the need to link against libavcodec. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>

2011-04-26setdar: prefer "sar" over "par" in log info messageStefano Sabatini
This is more consistent with the terminology adopted by the aspect filter names. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-04-26fade: fix draw_slice() check on fade->factor valueMark Himsley
draw_slice() checks that the fade factor is < 65536 and only calculates the fade if so. But the fade factor is clipped in end_frame() by av_clip_uint16() to 65535, so the fade is calculated for every frame. This patch alters the check so that it compares with < 65535 (UINT16_MAX). Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-04-26fade: make draw_slice() chroma check against planes 1 and 2Mark Himsley
draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data are not NULL before manipulating planes 1 and 2. This patch makes the check against planes 1 and 2. More senseful and possibly more robust. Signed-off-by: Anton Khirnov <anton@khirnov.net>

2011-02-15Merge libavcore into libavutilReinhard Tartler
It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

2011-02-04Make avfilter_graph_free() free the graph.Stefano Sabatini
Make avfilter_graph_free() free not only the internal structures, but also the allocated graph, and set the graph pointer to NULL for increased safety. Simplify usage. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-04Make avfilter_graph_parse() not free the input graphStefano Sabatini
Make avfilter_graph_parse() only release the internal structures allocated during the parsing, and leave to free the graph itself to the calling code. This approach looks cleaner, as the graph is not allocated by the function. Signed-off-by: Mans Rullgard <mans@mansr.com>

the evaluated value converted to int. That's required because -1 is evaluated as NAN, which converted back to int looks like a random number, this is especially annoying when debugging sources with undefined pos (as the video4linux2 device). Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
