* avcodec/cbs_av1: infer segmentation parameters from reference framesJames Almer2020-10-28
| | | | | | | | | Partially implements setup_past_independence() and load_previous(). These ensures they are always set, even if the values were not coded in the input bitstream and will not be coded in the output bitstream.

* lavf: move AVStream.info to AVStreamInternalAnton Khirnov2020-10-28
| | | | | | | This struct is for internal use of avformat_find_stream_info(), so it should not be exposed in public headers. Keep a stub pointer in its place to avoid changing AVStream layout, since e.g. ffmpeg.c accesses some fields located after it (even though they are marked as private).
* ffmpeg.c: stop accessing private AVStream.codec_info_nb_framesAnton Khirnov2020-10-28
| | | | | Use AVSTREAM_EVENT_FLAG_NEW_PACKETS instead, which should provide the same information in this case.

* put_bits: make avpriv_copy_bits() lavc-localAnton Khirnov2020-10-28

* put_bits: make avpriv_align_put_bits() inlineAnton Khirnov2020-10-28
| | | | | | | | | This function is so extremely simple that it is preferable to make it inline rather than deal with all the complications arising from it being an exported symbol. Keep avpriv_align_put_bits() around until the next major bump to preserve ABI compatibility.
* lavf/latmenc: use a local simplified copy of avpriv_copy_bits()Anton Khirnov2020-10-28
| | | | | This is the only place in lavf where avpriv_copy_bits() is used, so this allows us to make avpriv_copy_bits() lavc-local.
* lavf/latmenc: fix units mismatchAnton Khirnov2020-10-28
| | | | | | avpriv_copy_bits() takes the size in bits, not bytes. According to a736eb4a605f46d5ff96c7b32e55710ecd9cce89, nobody is quite sure whether this code produces working files.

* avcodec/bitstream: Stop allocating one VLCcode more than neededAndreas Rheinhardt2020-10-28
| | | | | | | | | Allocating one temporary entry more than needed was made necessary by the COPY loop below writing an element before having checked that it should be written at all. But given that this behaviour changed, the need for overallocating is gone. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| | | | | | | Neither the auxiliary VLC table nor the code_lengths array need to be freed if creating the auxiliary VLC table fails. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/webp: Use uint8_t for code lengthsAndreas Rheinhardt2020-10-27
| | | | | | | | | | They are always in the range 0..15, so using an int is not necessary. Furthermore, using an int would not work if sizeof(int) != 4 as ff_init_vlc_sparse() can only handle uint8_t, uint16_t and uint32_t lengths.

* avcodec/bitstream: Consistently treat symbol as VLC_TYPEAndreas Rheinhardt2020-10-27
| | | | | | | | | | | | | If a static VLC table gets initialized a second time (or concurrently by two threads) and if said VLC table uses symbols that have the sign bit of VLC_TYPE (a typedef for int16_t) set, initializing the VLC fails. The reason is that the type of the symbol in the temporary array is an uint16_t and so comparing it to the symbol read from the VLC table will fail, because only the lower 16bits coincide. Said failure triggers an assert. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/atrac3: Don't use too big VLC tablesAndreas Rheinhardt2020-10-27
| | | | | | | | | The longest code of any of the VLC tables used is eight bits long, so using nine bits long VLC tables is wasteful. Furthermore, there are only seven VLC tables used, yet the code up until now made it look like there should be eight. This has been corrected, too.
