* avcodec/mpegvideo_enc: Fix a chroma mb size error in sse_mb()Wenbin Chen2022-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avcodec/encode: Avoid check whose result is known in advanceAndreas Rheinhardt2022-07-09
| | | | | | | | | | | | | | | 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().

* Support for 16:9 DV in QuickTimeBrion Vibber2022-07-09
| | | | | | | | | | | | | | Some files I have from circa year 2000 are 16:9 NTSC DV video encoded as QuickTime with Radius SoftDV. This marked 4:3 videos with the box 'dvc ' for NTSC or 'dvcp' for PAL, which are already supported, but 16:9 videos as 'dvl ' or 'dvlp', which were not. Adding these to the list for DV codec processing gives the expected metadata and playback. I have not tested PAL as I have no sample data, only NTSC. Signed-off-by: Marton Balint <cus@passwd.hu>

* avutil/mem: Handle fast allocations near UINT_MAX properlyAndreas Rheinhardt2022-07-06
| | | | | | | | | | | | | | | | | | | | | av_fast_realloc and av_fast_mallocz? store the size of the objects they allocate in an unsigned. Yet they overallocate and currently they can allocate more than UINT_MAX bytes in case a user has requested a size of about UINT_MAX * 16 / 17 or more if SIZE_MAX > UINT_MAX (and if the user increased max_alloc_size via av_max_alloc). In this case it is impossible to store the true size of the buffer via the unsigned*; future requests are likely to use the (re)allocation codepath even if the buffer is actually large enough because of the incorrect size. Fix this by ensuring that the actually allocated size always fits into an unsigned. (This entails erroring out in case the user requested more than UINT_MAX.)
