| * cbs: Allocate the context inside the init functionMark Thompson2018-02-20

* | avformat/matroskadec: ignore CodecPrivate if the stream is VP9James Almer2018-02-19
| | | | | | | | | | | | | | | | | | | | | | Defined in a recent revision of https://www.webmproject.org/docs/container/ This prevents storing the contents of CodecPrivate into extradata for a codec that doesn't need nor expect any. It will among other things prevent matroska specific binary data from being dumped onto other formats during remuxing. Signed-off-by: James Almer <jamrial@gmail.com>

| * Revert "configure: Stop using dlltool to create an import library"Martin Storsjö2018-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 67c72f08a4707c18a67a4734660e3a23cc9488b6. While the linker produced import libraries might work with MSVC in simple test cases, they don't if e.g. linking to multiple GNU ld produced import libraries at the same time. (They end up importing functions from the wrong libraries.) The ones produced by dlltool work fine though. This issue was pointed out by Hendrik Leppkes.

* | build: restore using dlltool/lib.exe for creating Win32 .lib filesHendrik Leppkes2018-02-19

* | avcodec/mediacodecdec: refactor to take advantage of new decoding apiAman Gupta2018-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This refactor splits up the main mediacodec decode loop into two send/receive helpers, which are then used to rewrite the receive_frame callback and take full advantage of the new decoding api. Since we can now request packets on demand with ff_decode_get_packet(), the fifo buffer is no longer necessary and has been removed. This change was motivated by behavior observed on certain Android TV devices, featuring hardware mpeg2/h264 decoders which also deinterlace content (to produce multiple frames per field). Previously, this code caused buffering issues because queueInputBuffer() was always invoked before each dequeueOutputBuffer(), even though twice as many output buffers were being generated. With this patch, the decoder will always attempt to drain new frames first before sending more data into the underlying codec. Signed-off-by: Matthieu Bouron <matthieu.bouron@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes how NTSC VANC is extracted from the buffer. In NTSC the vanc data is interleaved between luma and chroma, and not just the luma as in high definition resolutions. In my testing this allows a decklink card encoding valid NTSC closed captions to pass the caption data to the x264 encoder. Updated with reviews from Devin Heitmueller and Marton Balint.
