Derek Buitenhuis	23c9ebffb5	avfilter: Properly check for failed format query Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	10 years ago
Nicolas George	099aff5c42	lavfi: check refcount before merging. When merging the formats around the automatically inserted convert filters, the refcount of the format lists can not be 0. Coverity does not detect it, and suspects a memory leak, because if refcount is 0 the newly allocated lists are not stored anywhere. That gives CIDs 1224282, 1224283 and 1224284. Lists with refcount 0 are used in can_merge_formats(), so the asserts can not be moved inside the merge functions.	10 years ago
Michael Niedermayer	5ab67340f9	avfilter/avfiltergraph: dont "or" together error codes Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	617e866e25	Move av_find_best_pix_fmt_of_2() from avcodec to avutil This avoids a dependancy of libavfilter on libavcodec See Ticket 3592 Fixes Ticket2784 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Yu Xiaolei	fbe9ae482d	avfilter: make avfilter_graph_get_filter use const string name Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Nicolas George	d300f5f6f5	lavfi/avfiltergraph: do not reduce incompatible lists. A list of "all channel layouts" but not "all channel counts" can not be reduced to a single unknown channel count.	11 years ago
Nicolas George	f775eb3fb4	lavfi/avfiltergraph: suggest a solution when format selection fails. Format selection can fail if unknown channel layouts are used with filters that do not support it.	11 years ago
Derek Buitenhuis	52aed19307	avfiltergraph: Properly handle memory allocation failure Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Michael Niedermayer	d5ec8ba7f2	Do not leave positive values undefined when negative are defined as error Define positive return values as non errors and leave further meaning undefined This allows future extensions to use these values Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	0767bfd199	lavfi: allow user-provided execute() callbacks	11 years ago
Anton Khirnov	77cc958f60	lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter() This function should never modify the filter.	11 years ago
Diego Biurrun	7950e519bb	Disable deprecation warnings for cases where a replacement is available	11 years ago
Michael Niedermayer	de0a1f63df	avfilter/can_merge_formats: fix memleak Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	6bde1e9d14	avfilter/avfiltergraph: fix check using the wrong variables Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	6a0b72f94f	avfilter/avfiltergraph: minor cosmetic Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	fe328f0807	avfilter: Dont partially merge lists This prevents the unneeded insertion of multiple aresample filters in some cases The format merging is moved to avoid having to call the channel layout merge twice. The channel layout merge code uses different structures and is not compatible with the added dry run wrappers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	5169111145	avfilter/REDUCE_FORMATS: fix bug that ended reducing too early Prior to this it was possible that format reduction was ended before it fully propagated leading to failure later in picking formats. No testcase with unmodified source exists, the case was reproduced with less aggressive list merging though. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	129bb23843	lavfi: add a slice threading infrastructure Mostly based on libavcodec's	12 years ago
Anton Khirnov	b01f6041f4	lavfi: rename AVFilterFormats.format_count to nb_formats This is more consistent with naming in the rest of Libav.	12 years ago
Anton Khirnov	096696ef0d	avfiltergraph: simplify inserting conversion filters. There is now no need to explicitly pass 0:0 as width/height to scale, those are the defaults.	12 years ago
Stefano Sabatini	5c4c929878	lavfi/avfiltergraph: fix style	12 years ago
Nicolas George	4582e4c086	lavfi: add comments to explain the negotiation loop.	12 years ago
Nicolas George	78d16b6a51	lavfi: fix filter format negotiation loop. query_formats() returning EAGAIN is not considered a progress in the format negotiation. If the filter returns EAGAIN but did set some of its formats lists, it could be considered a partial success and counted as progress in the negotiation. Not counting it is not a problem because it currently only happens in the first round, where there will always be some progress on the other filters.	12 years ago
Michael Niedermayer	0acf7e268b	avfilter: remove opaque passing hacks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	48a5adab62	lavfi: add avfilter_init_str() to replace avfilter_init_filter(). Drop the unused opaque parameter from its signature.	12 years ago
Anton Khirnov	1565cbc65c	lavfi: make avfilter_free() remove the filter from its graph.	12 years ago
Anton Khirnov	111367263a	lavfi: add AVFilterContext.graph. It will be useful in the following commits.	12 years ago
Anton Khirnov	c2c9801bc9	lavfi: deprecate avfilter_graph_add_filter(). Since this function adds a standalone filter to a filter graph and we do not support creating such filters, there is no reason for this function to exist.	12 years ago
Anton Khirnov	bc1a985ba0	lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). Since we do not support "standalone" filters not attached to an AVFilterGraph, we should not have a public function to create such filters. In addition that function is horribly named, the action it does cannot be possibly described as "opening" a filter.	12 years ago
Anton Khirnov	38f0c0781a	lavfi: merge avfiltergraph.h into avfilter.h We do not support using filters without AVFilterGraph in practice anyway, so there is no point in pretending we do.	12 years ago
Anton Khirnov	6d0546bbaf	avfiltergraph: set deprecated filter_count.	12 years ago
Anton Khirnov	6e3c13a559	avfiltergraph: check for sws opts being non-NULL before using them. Avoid snprintfing a NULL pointer. CC: libav-stable@libav.org	12 years ago
Nicolas George	125acd2152	lavfi: support multiple rounds of format negotiation. Remove the temporary hack for amerge and replace it with a generic solution.	12 years ago
Anton Khirnov	dd74e3ef33	avfiltergraph: use sizeof(var) instead of sizeof(type)	12 years ago
Anton Khirnov	42c7c61ab2	avfiltergraph: replace AVFilterGraph.filter_count with nb_filters This is more consistent with the naming in the rest of Libav.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Reimar Döffinger	88d55b827d	Remove incorrect use of ctype.h functions. As far as I can tell the code should not change behaviour depending on locale in any of these places. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Nicolas George	2d98dd3d14	lavfi: fix merging of formats and clarify exception. The following commit: `b97d61f` avfilter/ff_merge_formats: only merge if doing so does not loose chroma or alpha introduced an exception to avoid lossy conversions. Add a comment to explain the logic. Fix the call to avoid applying it on audio formats.	12 years ago
Justin Ruggles	9f1223562e	lavfi: connect libavresample options to af_resample via AVFilterGraph	12 years ago

Nicolas George	b6afb2dde1	lavfi: support unknown channel layouts.	12 years ago
Clément Bœsch	491ca0e89f	Replace references to "que" with the appropriate word. "que" sounds like a slang word to me. This commit renames a few variables, fix the comments and the logging messages (sometimes along with small other typo fixes).	12 years ago
