Hendrik Leppkes	79393a8363	Replace usage of the deprecated av_pix_fmt_descriptors array with av_pix_fmt_desc_get Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	e3496e5dbe	avfiltergraph: silence an uninitialized variable warning The warning is: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized] libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here Initialize it to an invalid value and add an assert that it's properly set later.	12 years ago

Michael Niedermayer	d40e2c7a86	avfiltergraph: kill uninitialized variable warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	743f07062a	lavfi: better channel layout negotiation Allow substitution of channel pairs in the input for nearby channel pairs in the output in order to get a closer match. Also weigh LFE channel mismatch differently to favor matching the same layout without LFE over one less channel with LFE.	13 years ago
Michael Niedermayer	ef1c0b5295	avfiltergraph: add some debug info about selected pixel formats Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	f98d814bb6	avfiltergraph: add a debug message on EOF.	13 years ago
Carl Eugen Hoyos	71e5a14028	Suggest aresample filter if it was not compiled but requested.	13 years ago
Anton Khirnov	61d158c321	avfiltergraph: shut up uninitialized variable warning. The warning silenced was: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:500:13: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized]	13 years ago
Anton Khirnov	8d900aa4d0	lavfi: remove disabled FF_API_GRAPH_AVCLASS cruft	13 years ago
Stefano Sabatini	972cad77fa	lavfi: remove unnecessary inclusion of libavcodec/avcodec.h in avfilter.h libavfilter API was designed in order to be clarly distinguished from the libavcodec API, including avcodec.h in avfilter.h is not going to help to stick to this principle. The inclusion of libavutil/audioconvert.h in many files was required because avcodec.h includes audioconvert.h. libavfilter/avcodec.h is where the lavc/lavfi interface should be entirely placed.	13 years ago
Anton Khirnov	58b049f2fa	lavfi: support automatically inserting the fifo filter when needed. This breaks libavfilter ABI.	13 years ago
Paul B Mahol	54101214d8	lavfi: use designated initializers for AVClass While here: - add missing .version and .category, - make .class_name consistent across filters, - align declarations. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Paul B Mahol	c9e183b490	lavfi: update some deprecated functions Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Anton Khirnov	24b2f4ed21	avfiltergraph: remove a redundant call to avfilter_get_by_name().	13 years ago
Anton Khirnov	2f296e39a1	lavfi: allow building without swscale.	13 years ago
Anton Khirnov	9baeff9506	lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs This is more consistent with naming in the rest of Libav.	13 years ago
Andrew Wason	c527027c27	aconvert filter needs to configure samplerates I changed the _set_common_ functions to only set unset formats, then added a wrapper that calls them after the filters query_formats. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	aba8065adb	avfiltergraph: call query_formats on inputs first. This is a temporary workaround for amerge, until format renegociation is implemented. Should fix trac ticket #1400.	13 years ago
Nicolas George	6a4c5c730e	avfiltergraph: check query_formats return value.	13 years ago
Anton Khirnov	b74a1da49d	lavfi: make formats API private on next bump. It is only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	8eb9bf0933	avfiltergraph: make some functions static. They are not used outside of avfiltergraph.c	13 years ago
Stefano Sabatini	0f0f3bd1e0	lavfi: use av_default_item_name() as filter private context logger avfilter_default_filter_name() is supposed to access an AVFilterContext struct, if used with a private struct it will cause a crash since it will access fields which are non defined in the private struct.	13 years ago
Stefano Sabatini	4d6a8a2bdb	lavfi: add avfilter_default_filter_name() The function is modelled after av_default_item_name(), and will print the name of the instance filter if defined, otherwise the name of the filter. This allows to show the instance name in the log, which is useful when debugging complex filter graphs.	13 years ago
Anton Khirnov	43c7a01e98	lavfi: remove avfilter_default_* from public API on next bump. Those functions are only useful inside filters. It is better to not support user filters until the API is more stable.	13 years ago
Anton Khirnov	ccefa89f39	avfiltergraph: smarter sample format selection.	13 years ago
Michael Niedermayer	3ae64dc48f	avfiltergraph: use aresample not aconvert in the alternative merge code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	4d4098da00	lavfi: drop planar/packed negotiation support 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.	13 years ago
Michael Niedermayer	88d5cfe7c8	avfiltergraph: switch to swresample by default all known bugs in the interface code have been fixed Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	fd127ede62	avfiltergraph: reindent	13 years ago
Anton Khirnov	ff1f51a8aa	lavfi: add channel layout/sample rate negotiation.	13 years ago
Nicolas George	440af105f2	lavfi: add avfilter_graph_set_auto_convert().	13 years ago
Anton Khirnov	012f04a277	lavfi: autoinsert resample filter when necessary.	13 years ago
Michael Niedermayer	7610dee87b	avfiltergraph: improve pick_format() without this the recent changes to format/sink handling would cause a regression in fate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	fd2cd64fc9	avfiltergraph: fix format selection. 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.	13 years ago
Nicolas George	2e8f19d26f	avfiltergraph: free the sink_links heap.	13 years ago
Nicolas George	2ce7972779	avfiltergraph: add avfilter_graph_request_oldest(). Keep a heap of all sink links ordered by timestamps.	13 years ago
Nicolas George	e0761feec4	avfilter: add a pointer from links to graph.	13 years ago
Michael Niedermayer	0d115d7799	avfiltergraph: More advanced heuristic to select colorspace. This fixes regressions caused by switching from ffmpegs system to avfilters. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	63736fe48c	avfiltergraph: try to reduce format conversions in filters. 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)	13 years ago
Anton Khirnov	996f9f0c32	avfiltergraph: add an AVClass to AVFilterGraph on next major bump. It will be used for logging, possibly also AVOptions.	13 years ago
Nicolas George	42655b24c2	avfiltergraph: avoid harmful auto audio conversions. 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.	13 years ago
