* avformat/mov: Expose encryption info to the app.Jacob Trimble2018-07-04
| | | | | | | | | | This exposes encryption info from the container to the app. This includes key ID, IV, and subsample byte ranges. The info is passed using the new side-data AV_PKT_DATA_ENCRYPTION_DATA and AV_PKT_DATA_ENCRYPTION_INIT_DATA.

* lavc: implement an ATRAC9 decoderRostislav Pehlivanov2018-07-03
| | | | | | | | | | | | | | | | | | | | This commit implements a full ATRAC9 decoder, a simple low-delay codec developed by Sony and used in most PSVita games, some PS3 games and some PS4 games. Its similar to AAC in that it uses Huffman coded scalefactors but instead of vector quantization it just Huffman codes the spectral coefficients (in a way similar to how Opus splits band energy coding into coarse and fine precision). It opts to write rather large Huffman codes by packing several small coefficients into one Huffman coded symbol, though I don't believe this increases efficiency at all. Band extension implements SBC in a simple way, first it mirrors the lower spectrum onto the higher frequencies and then it uses one of 5 filters to shape it. Noise substitution is implemented via 2 of them. Unlike previous ATRAC codecs, there's no QMF, this is a standard MDCT codec. Based off of the reverse engineering work of Alex Barney.

* avformat/apngdec: set pts to AV_NOPTS_VALUEMarton Balint2018-07-02
| | | | | | | | | And let the generic code figure out the proper PTS. This is needed because apng does not provide seek functions, but after a generic seek (e.g. to file start) timestamps are not reset which causes broken timestamps when looping apngs, like in ticket #6121.

* avcodec/vc1: fix overlap filter for frame interlaced picturesJerome Borsboom2018-06-29
| | | | | | | | | | The overlap filter is not correct for vertical edges in frame interlaced I and P pictures. When filtering macroblocks with different FIELDTX values, we have to match the lines at both sides of the vertical border. In addition, we have to use the correct rounding values, depending on the line we are filtering. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
* avcodec/vc1: change the internal ordering of blocks within a macroblockJerome Borsboom2018-06-29
| | | | | | | | | | The overlap filter needs to cover a full macroblock vertical edge when the FIELDTX value for two neighbouring macroblocks is not equal. By changing the internal ordering of the blocks from row major to column major, we do not need to reinterlace a FIELDTX coded macroblock before running the overlap filter.

* h264_slice: Fix return of incomplete frames from decoderJohn Stebbins2018-06-28
| | | | | | | | | | | When not using libavformat for demuxing, AVCodecContext.has_b_frames gets set too late causing the recovery frame heuristic in h264_refs to incorrectly flag an early frame as recovered.
