* bump msgq * add third_party/linux/include/media/msm_vidc.h * add sde_rotator hw interface * add msm_vidc hw decoder interface * update SConscript to build qcom decoder and rotator * use qcom decoder in replay framereader * decode directly to NV12 with the correct stride without using the hw rotator * bump msgq back to master * don't compile rotator * cleanup * works now but much to simplify * rm signals * rm header --------- Co-authored-by: Test User <test@example.com> Co-authored-by: Adeeb Shihadeh <adeebshihadeh@gmail.com>
