* lavfi: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.

* | vf_overlay: handles expression evaluation of frame size change in ↵Bela Bodecs2016-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | frame-by-frame evalutaion mode vf_overlay video filter accepts expressions in its parameters. In 'frame-by-frame' evaluation mode it recalculates them regularly, but incoming video frame size changes did not reflect in their values. So if you used width or height of any source videos in expressions as parameters, they stayed on their initial values. This patch corrects this bug.

* | lavfi/vf_overlay: fix memory leaksGanesh Ajjanagadde2015-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent commits 6aaac24d72a7da631173209841a3944fcb4a3309 and 3835554bf8ed78539a3492c239f979c0ab03a15f made progress towards cleaning up usage of the formats API, and in particular fixed possible NULL pointer dereferences. This commit addresses the issue of possible resource leaks when some intermediate call fails. Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation of malloc/realloc failures. Fixes: CID 1338327. 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.

| | | | | | | | | | | | | | | | | | | | | | This is especially useful to debug queue overflow issues. Ideally we should be able to set the debug message at the dualinput/framesync level, but they do not have the information related to the filter context and the inlink, so cannot access much useful information.
