* avcodec/h264_slice: compute and export film grain seedNiklas Haas2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | From SMPTE RDD 5-2006, the grain seed is to be computed from the following definition of `pic_offset`: > When decoding H.264 | MPEG-4 AVC bitstreams, pic_offset is defined as > follows: > - pic_offset = PicOrderCnt(CurrPic) + (PicOrderCnt_offset << 5) > where: > - PicOrderCnt(CurrPic) is the picture order count of the current frame, > which shall be derived from [the video stream]. > > - PicOrderCnt_offset is set to idr_pic_id on IDR frames. idr_pic_id > shall be read from the slice header of [the video stream]. On non-IDR I > frames, PicOrderCnt_offset is set to 0. A frame shall be classified as I > frame when all its slices are I slices, which may be optionally > designated by setting primary_pic_type to 0 in the access delimiter NAL > unit. Otherwise, PicOrderCnt_offset it not changed. PicOrderCnt_offset is > updated in decoding order.

* avformat/matroskaenc: Pass dispositions through unchanged by defaultAndreas Rheinhardt2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, the Matroska muxer did not use the dispositions it is given as-is; instead it by default overrode the disposition of the first track of a kind (audio, video, subtitles) if no track of this kind has the default disposition set. And up until recently, it also enforced by default that no more than one track of each kind be marked as default. The rationale for the former is that there are lots of containers which lack the concept of default streams, so that it is not uncommon for no stream to be marked as default at all; the rationale for the latter was that up until recently, it was dubious whether the Matroska specification allowed more than one default stream for track type (e.g. mkvmerge disallowed it). It was this point which led to the implementation of the above mentioned behaviour inspired by mkvmerge. Yet the Matroska specifications have changed and now explicitly allow to set more than one track of each type as default, so that the main reason of not using the dispositions as-is was rendered moot. Therefore this commit changes the default to pass the disposition through. The matroska-mpegts-remux FATE-test has been updated to still use the old "infer" mode so that it is still covered by FATE; the matroska-zero-length-block test has also been updated to cover the infer_no_subs mode. The references for lots of other FATE tests needed to be updated because of a newly added FlagDefault element with value zero (whereas a FlagDefault with value 1 needn't be coded at all, as it coincided with the default value of said element).

* avformat/matroskaenc: Allow to set multiple streams as defaultAndreas Rheinhardt2021-08-24
| | | | | | | | | | The Matroska specifications have evolved and now allow to mark multiple tracks of the same kind as default (whether this was legal or not before was dubious; e.g. mkvmerge disallowed it). Yet when the Matroska muxer is set to infer default dispositions if absent, it also enforced the now outdated restriction. So update this.

* avformat/av1dec: Disallow seeking by bytesAndreas Rheinhardt2021-08-23

* avformat/av1dec: Flush BSF upon seekingAndreas Rheinhardt2021-08-23
| | | | | | | | | | | | | | The av1_merge_frame BSF outputs its cached data when it sees the beginning of a new frame, i.e. when it sees a temporal delimiter OBU. Therefore it typically has a temporal delimiter OBU cached after outputting a packet. This implies that the OBU demuxer must flush its BSF upon seeking because otherwise the first frame returned after a seek consists of an old temporal delimiter OBU only.
