* swresample/arm: remove unintentional relocation.Rahul Chaudhry2018-06-181-2/+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> (cherry picked from commit b22db4f465c9adb2cf1489e04f7b65ef6bb55b8b) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* 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>
