* | Parse and drop gain control data, so that SSR packets decode.Dale Curtis2018-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This will result in poor quality audio for SSR streams, but they will at least demux and decode without error; partially fixing ticket #1693. This pulls in the decode_gain_control() function from the ffmpeg summer-of-code repo (original author Maxim Gavrilov) at svn://svn.mplayerhq.hu/soc/aac/aac.c with some minor modifications and adds AOT_AAC_SSR to decode_audio_specific_config_gb().

* | vaapi: Add MJPEG decode hwaccelMark Thompson2018-02-21

* | vaapi_decode: Make the frames context format selection more generalMark Thompson2018-02-21
| | | | | | | | | | Examine the supported fourcc list manually and make the best choice, then use the external attribute on the frames context to force that fourcc.
* | mjpegdec: Add hwaccel hooksMark Thompson2018-02-21
| | | | | | | | | | Also adds some extra fields to the main context structure that may be needed by a hwaccel decoder.
* | lavc/mjpeg: Add profiles for MJPEG using SOF marker codesMark Thompson2018-02-21
| | | | | | | | | | | | This is needed by later hwaccel code to tell which encoding process was used for a particular frame, because hardware decoders may only support a subset of possible methods.

| * cbs: Refcount all the things!Mark Thompson2018-02-20
| | | | | | | | | | | | | | | | This makes it easier for users of the CBS API to get alloc/free right - all subelements use the buffer API so that it's clear how to free them. It also allows eliding some redundant copies: the packet -> fragment copy disappears after this change if the input packet is refcounted, and more codec-specific cases are now possible (but not included in this patch).

* | 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>
