* avcodec/mpegvideo_dec: Remove commented-out cruftAndreas Rheinhardt2022-02-13
| | | | | | | | | | This piece of code has been added in an already commented-out state in commit 158c7f059c3906b0116ae73a7669a3bb7bc570bb. It certainly doesn't make sense now (if ever) because new_picture_ptr it used has been removed in 6571e41dcdee4655237bca0a3277df8976167aee (and new_picture is only used for encoding).

* avcodec/mpegvideo_enc: Don't find encoder by IDAndreas Rheinhardt2022-02-13
| | | | | | | | | | | | mpegvideo-based encoders supporting bframes implement this by opening encoders of their own to test how long the chains of bframes are supposed to be. The needed AVCodec was obtained via avcodec_find_encoder(). This is complicated, as the current encoder can be directly obtained. And it also is not guaranteed that one actually gets the current encoder or not another encoder for the same codec ID (the latter does not seem to be the case now).

* avcodec/mpegvideo: Enable private contextsAndreas Rheinhardt2022-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MpegEncContext is used by many different codecs and every one of these uses just a subset of its fields. If one tries to separate this and e.g. add a real MpegContext and extension structures (say MpegDecContext and MpegEncContext), one runs into two difficulties: a) Some code is shared between decoder and encoder of the same format and they therefore use the same contexts, either MpegEncContext itself or identical extensions thereof. The latter is the case for H.261 as well as WMV2. b) In case of slice threading, the generic code can only allocate and initialize the structure it knows about; right now this is an MpegEncContext. If the codec has an even more extensive structure, it is only available for the main thread's MpegEncContext. Fixing this would involve making ff_mpv_common_init() aware of the size the size of slice context to allocate and would be part of separating the main thread's context from the slice contexts in general. This commit only intends to tackle the first issue by adding a pointer to MpegEncContext that codecs can set to a common context so that the aforementioned codecs can use this context (together with the MpegEncContext) in their common code. This will allow to move fields only used by the main thread to more specialized contexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* fftools/ffmpeg: Restore DTS correction for VP9 copiesDanny Wu2022-02-13
| | | | | | | | | | | | | | | | | | Fixes ticket 9086. Since early 2021, some of YouTube's VP9 encodes have non-monotonous DTS. This makes ffmpeg fatally fail when trying to copy or encode the V9 video. ffmpeg already includes functionality to correct this, however it was disabled without explanation for VP9 stream copies in 2e6636aa87303d37b112e79f093ca39500f92364 This patch restores the DTS correction logic, and allows ffmpeg to correctly encode (invalid) videos produced by youtube.com. I have verified that frames are NOT being cut (so it does not re-introduce 4313). Reviwed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
