2013-04-30graphparser: only print filter arguments if they are non-NULLAnton Khirnov
2013-04-11lavfi: add avfilter_init_str() to replace avfilter_init_filter().Anton Khirnov
Drop the unused opaque parameter from its signature.
2013-04-11lavfi: make avfilter_free() remove the filter from its graph.Anton Khirnov
2013-04-11lavfi: replace avfilter_open() with avfilter_graph_alloc_filter().Anton Khirnov
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.
2013-04-11lavfi: merge avfiltergraph.h into avfilter.hAnton Khirnov
We do not support using filters without AVFilterGraph in practice anyway, so there is no point in pretending we do.
2013-04-03avfiltergraph: check for sws opts being non-NULL before using them.Anton Khirnov
Avoid snprintfing a NULL pointer. CC: libav-stable@libav.org
2013-03-16avfiltergraph: replace AVFilterGraph.filter_count with nb_filtersAnton Khirnov
This is more consistent with the naming in the rest of Libav.

Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>

Fixes CID700635, CID700636 and CID732274.

2012-06-26lavfi: remove disabled FF_API_GRAPH_AVCLASS cruftAnton Khirnov
2012-06-13lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputsAnton Khirnov
This is more consistent with naming in the rest of Libav.
2012-04-16graphparser: set next to NULL on an entry extracted from inputs listAnton Khirnov
Prevents it from referring to the rest of the list.
2012-04-15graphparser: fix the order in which unlabeled input links are returned.Anton Khirnov
2012-04-14avfiltergraph: make the AVFilterInOut alloc/free API publicStefano Sabatini
This is required for letting applications to create and destroy AVFilterInOut structs in a convenient way. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2012-04-14graphparser: allow specifying sws flags in the graph description.Anton Khirnov
2012-04-14graphparser: fix the order of connecting unlabeled links.Anton Khirnov
Right now, e.g. scale,[in]overlay would connect scale to the first overlay input and [in] to the second, which goes against the documentation and is unintuitive. The bug happens because of the ordering mess in curr_inputs variable: 1) the unlabeled links from the previous filter are added to it in correct order 2) input labels are parsed and inserted to the beginning one by one (i.e. in reverse order) 3) curr_inputs is matched against filter inputs in reverse order Fix the problem by always using proper ordering without trying to be clever.
2012-04-14graphparser: add avfilter_graph_parse2().Anton Khirnov
Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs to the caller, which allows parsing of graphs where inputs/outputs are not known in advance.
2011-09-28lavfi: fix signature for avfilter_graph_parse() and avfilter_graph_config()Stefano Sabatini
Require "void *" rather than "AVClass *" for the log context type. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-09-28graphparser: prefer void * over AVClass * for log contextsStefano Sabatini

2011-07-03doxygen: Fix parameter names to match the function prototypes.Diego Biurrun
2011-04-26graphparser: add a NULL check on the argument passed to strstrStefano Sabatini
Fix crash in create_filter() which occurrs if a scale filter with no args is provided. Signed-off-by: Anton Khirnov <anton@khirnov.net>

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>

2010-11-07Rename the variable filter to filt_ctx in link_filter_inouts, as the ↵Stefano Sabatini

AVFilterContext *avfilter_open(AVFilter *filter, const char *inst_name); to: int avfilter_open(AVFilterContext **filter_ctx, AVFilter *filter, const char *inst_name); This way it is possible to propagate an error code telling the reason of the failure.
