Ramiro Polla	b8af0809fb	libavcodec/mpegvideo_enc: fix multi-threaded motion estimation rounding for mpeg4 ff_init_me() was being called after ff_update_duplicate_context(), which caused the propagation of the initialization to other thread contexts to be delayed by one frame. In the case of mpeg4 (or flipflop_rounding), this would make the hpel_put functions differ between the first thread (which would be correctly initialized) and the other threads (which would be stale from the previous frame).	10 months ago
Ramiro Polla	713c6eba8d	libavcodec/motion_est: fix penalty_factor for b frames In direct_search() and ff_estimate_b_frame_motion(), penalty_factor would be used before being initialized in estimate_motion_b(). Also, the initialization would happen more than once unnecessarily.	10 months ago

Andreas Rheinhardt	6fa967810d	tests/checkasm/svq1enc: Use proper range for input ssd_int8_vs_int16 is only called from encode_block() in svq1enc.c; it calls it in stages: At stage 0, the int16_t array contains the difference of two uint16_t. At each of the following stages, the int16_t array is filled by subtracting an int8_t from the current stage's int16_t array. The maximum stage is five, so the int16_t are in the range (-255 - 5 * 127)..(255 + 5 * 128). This commit modifies the checkasm test to only use values from this range, fixing (undefined) integer overflow in the test.
