This resulted in the wrong column/row being chosen. This can be seen best when using xfade on streams with transparency. For example: in case of a slideleft transition, the first column from the first input will overwrite the first column of the second stream throught the transition.

2022-07-09avcodec/mpegvideo_enc: Fix a chroma mb size error in sse_mb()Wenbin Chen
For 422 frames we should not use hard coded 8 to calculate mb size for uv plane. Chroma shift should be taken into consideration to be compatiple with different sampling format. The error is reported by fate test when av_cpu_max_align() return 64 on the platform supporting AVX512. This is a hidden error and it is exposed after commit 17a59a634c39b00a680c6ebbaea58db95594d13d. mpeg2enc has a mechanism to reuse frames. When it computes SSE (sum of squared error) on current mb, reconstructed mb will be wrote to the previous mb space, so that the memory can be saved. However if the align is 64, the frame is shared in somewhere else, so the frame cannot be reused and a new frame to store reconstrued data is created. Because the height of mb is wrong when compute sse on 422 frame, starting from the second line of macro block, changed data is read when frame is reused (we need to read row 16 rather than row 8 if frame is 422), and unchanged data is read when frame is not reused (a new frame is created so the original frame will not be changed). That is why commit 17a59a634c39b00a680c6ebbaea58db95594d13d exposes this issue, because it add av_cpu_max_align() and this function return 64 on platform supporting AVX512 which lead to creating a frame in mpeg2enc, and this lead to the different outputs.

2022-07-09avcodec/encode: Avoid check whose result is known in advanceAndreas Rheinhardt
encode_send_frame_internal() is always only called if the buffer packet is empty and except when we are dealing with an audio codec that does not allow variable frame size it stays that way until a call to av_frame_ref() at the end of encode_send_frame_internal(). In case we are dealing with the small last frame of an audio encoder requiring constant frame size the frame will be allocated by pad_last_frame() and this the only case where this is so. So by returning directly after pad_last_frame(), we can avoid having to recheck whether the frame is still empty before av_frame_ref().
