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).	6 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.	6 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.
