2015-12-12avfilter/vf_delogo: Use AVPixFmtDescriptor.nb_componentsJean Delvare

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. Unfortunately, even leaving aside this subtle intermediate failure aspect, commit 8087632027d755cd32ccc9e91ea025e276197055 was only partially successful in addressing memleaks. Hopefully, this commit fixes the issue completely. Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation of malloc/realloc failures. Fixes: CID 1270818.

2015-12-09avfilter/vf_delogo: round to the closest valueJean Delvare
When the interpolated value is divided by the sum of weights, no rounding is done, which means the value is truncated. This results in a slight bias towards dark green in the interpolated area. Rounding properly removes the bias. I measured this change to reduce the interpolation error by 1 to 2 % on average on a number of sample input and logo area combinations.

2015-11-26avfilter/af_afade: improve accuracy and speed of gain computationGanesh Ajjanagadde
Gain computation for various curves was being done in a needlessly inaccurate fashion. Of course these are all subjective curves, but when a curve is advertised to the user, it should be matched as closely as possible within the limitations of libm. In particular, the constants kept here were pretty inaccurate for double precision. Speed improvements are mainly due to the avoidance of pow, the most notorious of the libm functions in terms of performance. To be fair, it is the GNU libm that is among the worst, but it is not really GNU libm's fault since others simply yield a higher error as measured in ULP. "Magic" constants are also accordingly documented, since they take at least a minute of thought for a casual reader.
