2018-07-26swresample: Use channel count in rematrix initializationMarcin Gorzel
Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails. This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2018-07-21libavcodec/ppc: Fix HEVC AltiVec routines with --enable-smallA. Wilcox
GCC requires the argument to vec_splat_u32 to be a literal. The easiest way to accomplish this is to change 'shift' to be const in scale (as it is in the transform routine above), and convert both routines to be inline. This way, GCC can coerce the values to literals. Tested on a 970 (Apple G5) and POWER9 (Talos II); passed fate and played a clip of Big Buck Bunny correctly. Fixes ticket #7048 Signed-off-by: A.

2018-07-15Update Changelog for lensfun addition and bump minorPaul B Mahol
2018-07-15Add lensfun filterStephen Seo
Lensfun is a library that applies lens correction to an image using a database of cameras/lenses (you provide the camera and lens models, and it uses the corresponding database entry's parameters to apply lens correction). It is licensed under LGPL3. The lensfun filter utilizes the lensfun library to apply lens correction to videos as well as images. This filter was created out of necessity since I wanted to apply lens correction to a video and the lenscorrection filter did not work for me. While this filter requires little info from the user to apply lens correction, the flaw is that lensfun is intended to be used on indvidual images. When used on a video, the parameters such as focal length is constant, so lens correction may fail on videos where the camera's focal length changes (zooming in or out via zoom lens). To use this filter correctly on videos where such parameters change, timeline editing may be used since this filter supports it. Note that valgrind shows a small memory leak which is not from this filter but from the lensfun library (memory is allocated when loading the lensfun database but it somehow isn't deallocated even during cleanup; it is briefly created in the init function of the filter, and destroyed before the init function returns). This may have been fixed by the latest commit in the lensfun repository; the current latest release of lensfun is almost 3 years ago. Bi-Linear interpolation is used by default as lanczos interpolation shows more artifacts in the corrected image in my tests. The lanczos interpolation is derived from lenstool's implementation of lanczos interpolation. Lenstool is an app within the lensfun repository which is licensed under GPL3. v2 of this patch fixes license notice in libavfilter/vf_lensfun.c v3 of this patch fixes code style and dependency to gplv3 (thanks to Paul B Mahol for pointing out the mentioned issues). v4 of this patch fixes more code style issues that were missed in v3. v5 of this patch adds line breaks to some of the documentation in doc/filters.texi (thanks to Gyan Doshi for pointing out the issue). v6 of this patch fixes more problems (thanks to Moritz Barsnick for pointing them out). v7 of this patch fixes use of sqrt() (changed to sqrtf(); thanks to Moritz Barsnick for pointing this out). Also should be rebased off of latest master branch commits at this point. Signed-off-by: Stephen Seo <seo.disparate@gmail.com>
2018-07-14aadec: improve seeking in mp3 contentKarsten Otto
MP3 frames may not be aligned to aa chunk boundaries. When seeking, calculate the expected frame offset in the target chunk. Adjust the timestamp and truncate the next packet accordingly. This solution works for the majority of tested audio material. For some rare encodings with mp3 padding or embedded id3 tags, it will mispredict the correct offset, and at worst skip an extra frame.
