Ganesh Ajjanagadde	31f0d555e0	lavfi/vf_alphamerge: fix memory leaks Recent commits `6aaac24d72` and `3835554bf8` 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.

Ganesh Ajjanagadde	6aaac24d72	avfilter/all: propagate errors of functions from avfilter/formats 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.

Steven Robertson	82ecae8a70	lavfi: add alphaextract and alphamerge filters 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.
