* avfilter/vf_alphamerge: Fix double-free of AVFilterFormats on errorAndreas Rheinhardt2020-08-23
| | | | | | | | | | | | | | | | | | | | | | | The query_formats function of the alphamerge filter tries to allocate two lists of formats which on success are attached to more permanent objects (AVFilterLinks) for storage afterwards. If attaching a list to an AVFilterLink succeeds, the link becomes one of the owners of the list. Yet if attaching a list to one of its links succeeds and an error happens lateron, both lists were manually freed, which is wrong if the list is already owned by one or more links; these links' pointers to their lists will become dangling and there will be a double-free/use- after-free when these links are cleaned up automatically. This commit fixes this by removing the custom freeing code; this will temporarily add a leaking codepath (if attaching a list not already owned by a link to a link fails, the list will leak), but this will be fixed soon by making sure that an AVFilterFormats without owner will be automatically freed when attaching it to an AVFilterLink fails. At most one list leaks because as of this commit a new list is only allocated after the old list has been successfully attached to a link.

* lavfi/vf_alphamerge: 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 1338326, 1338329. 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: add alphaextract and alphamerge filtersSteven Robertson2012-07-22
These filters are designed for storing and transmitting video sequences with alpha using higher-efficiency codecs such as x264 which don't natively support an alpha channel. 'alphaextract' takes an input stream with an alpha channel and returns a video containing just the alpha component as a grayscale value; 'alphamerge' takes an RGB or YUV stream and adds an alpha channel recovered from a second grayscale stream.
