* | avfiltergraph: use aresample not aconvert in the alternative merge code.Michael Niedermayer2012-05-171-1/+1
| | | | | | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | lavfi: drop planar/packed negotiation supportStefano Sabatini2012-05-161-10/+6
| | | | | | | | | | | | | | | | | | The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.

* | avfiltergraph: fix format selection.Nicolas George2012-04-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The old code had two bugs: For audio filters, the format was not set. For video filters, if several links reference the same format list, the same format must be selected in the end. This is done by setting formats->format_count to 1: the other links sharing the reference will therefore have only one choice. If the heuristic does not pick the first format, the selected format must also be moved to the first position.

| * avfiltergraph: try to reduce format conversions in filters.Anton Khirnov2012-04-011-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)
| * avfiltergraph: add an AVClass to AVFilterGraph on next major bump.Anton Khirnov2012-04-011-1/+15
| | | | | | | | It will be used for logging, possibly also AVOptions.

* | avfiltergraph: avoid harmful auto audio conversions.Nicolas George2012-02-231-3/+8
| | | | | | | | | | | | | | | | With the current code, an automatically inserted aconvert necessary for format change would usually convert to mono for no good reason. The new code will not avoid all conversions, but at least will keep them among the layouts common to both filters.

* Generalize pixel format enum fields to int formats.S.N. Hemanth Meenakshisundaram2010-07-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
