* avfilter/avfiltergraph: Clear graph pointers in ff_filter_graph_remove_filter()Michael Niedermayer2016-05-27
| | | | | | | When a filter is no longer part of a graph, its pointers should be cleared so no stale pointers remain. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* lavfi: make request_frame() non-recursive.Nicolas George2015-12-22
| | | | | | | Instead of calling the input filter request_frame() method, ff_request_frame() now marks the link and returns immediately. buffersink is changed to activate the marked filters until a frame is obtained.
* lavfi: rename link.current_pts to current_pts_us.Nicolas George2015-12-22
| | | | | | | This field is used for fast comparison between link ages, it is in AV_TIME_BASE units, in other words microseconds, µs =~ us. Renaming it allows a second field in link time base units.
* avfilter/avfiltergraph: fix -Wunused-result warningsGanesh Ajjanagadde2015-10-16
| | | | | | | | | | | | Commit bf0d2d6030c239f91e0368a20fb2dc0705bfec99 introduced av_warn_unused_result to avfilter/formats, whose associated warnings were mostly fixed in 6aaac24d72a7da631173209841a3944fcb4a3309. This fixes the issues in avfilter/avfiltergraph. Tested with FATE. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.

* | lavfi: check refcount before merging.Nicolas George2014-07-17
| | | | | | | | | | | | | | | | | | | | 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.

* | lavfi: fix filter format negotiation loop.Nicolas George2013-05-07
| | | | | | | | | | | | | | | | | | | | | | 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.
