* swresample/swresample: Fix input channel count in resample_first computationMichael Niedermayer2018-07-261-1/+1

* swresample: Use channel count in rematrix initializationMarcin Gorzel2018-07-262-4/+4
| | | | | | | | 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>

* swresample/arm: remove unintentional relocation.Rahul Chaudhry2018-04-191-2/+4
| | | | | | | | | | | | | | | | | | Branch to global symbol results in reference to PLT, and when compiling for THUMB-2 - in a R_ARM_THM_JUMP19 relocation. Some linkers don't support this relocation (ld.gold), while others can end up truncating the relocation to fit (ld.bfd). Convert this branch through PLT into a direct branch that the assembler can resolve locally. See https://github.com/android-ndk/ndk/issues/337 for background. The current workaround is to disable neon during gstreamer build, which is not optimal and can be reverted after this patch: https://github.com/freedesktop/gstreamer-cerbero/commit/41556c415739fbc3a72c7eaee7e70a565b719b2f Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | | | | | | | | | | * commit '07a2b155949eb267cdfc7805f42c7b3375f9c7c5': Bump major versions of all libraries A few API deprecated ~2 years ago or more are also postponed here for varying reasons. FF_API_LOWRES: Since this functionality depends on AVStream->codec, i figure the two can be removed at the same time in the next bump or so. FF_API_AVCTX_TIMEBASE: Couldn't get this one to work. Not just libavcodec but apparently also libavformat and ffmpeg.c expect AVCodecContext->time_base to be set for decoding. Upon removal some tests report a different generic stream time base (like 1/25), and others lose packet duration values. I guess it's somehow tied to the AVStream->codec clusterfuck. It can be dealt with alongside FF_API_LAVF_AVCTX in the next bump. FF_API_OLD_FILTER_OPTS_ERROR: This one is meant to remain after FF_API_OLD_FILTER_OPTS is removed. Its purpose is displaying the corrected command line using the new syntax as a suggestion as part of the error message. Merged-by: James Almer <jamrial@gmail.com>

* libswresample: check input to swr_convert_frame for NULLhexpointer2017-07-081-3/+4
| | | | | | | | | When 'out' is an AVFrame that does not have buffers preallocated, swr_convert_frame tries to allocate buffers of the right size. However in calculating this size it failed to check for whether 'in' is NULL (requesting that swr's internal buffers are to be flushed). Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
