| * decode: restructure the core decoding codeAnton Khirnov2016-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the new decoding API is pretty much just a wrapper around the old deprecated one. This is problematic, since it interferes with making full use of the flexibility added by the new API. The old API should also be removed at some future point. Reorganize the code so that the new send_packet/receive_frame functions call the actual decoding directly and change the old deprecated avcodec_decode_* functions into wrappers around the new API. The new internal API for decoders is now changing as well. Before this commit, it mirrors the public API, so the decoders need to implement send_packet() and receive_frame() callbacks. This turns out to require awkward constructs in both the decoders and the generic code. After this commit, the decoders only implement the receive_frame() callback and call a new internal function, ff_decode_get_packet() to obtain input data, in the same manner to how the bitstream filters now work. avcodec will now always make a reference to the input packet, which means that non-refcounted input packets will be copied. Keeping the previous behaviour, where this copy could sometimes be avoided, would make the code significantly more complex and fragile for only dubious gains, since packets are typically small and everyone who cares about performance should use refcounted packets anyway.

| * decode: be more explicit about storing the last packet propertiesAnton Khirnov2016-12-14
| | | | | | | | | | | | | | | | | | | | | | The current code stores a pointer to the packet passed to the decoder, which is then used during get_buffer() for timestamps and side data passthrough. However, since this is a pointer to user data which we do not own, storing it is potentially dangerous. It is also ill defined for the new decoding API with split input/output. Fix this problem by making an explicit internally owned copy of the packet properties.

| * lavc: introduce a new decoding/encoding API with decoupled input/outputwm42016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the decoding API was restricted to outputting 0 or 1 frames per input packet. It also enforces a somewhat rigid dataflow in general. This new API seeks to relax these restrictions by decoupling input and output. Instead of doing a single call on each decode step, which may consume the packet and may produce output, the new API requires the user to send input first, and then ask for output. For now, there are no codecs supporting this API. The API can work with codecs using the old API, and most code added here is to make them interoperate. The reverse is not possible, although for audio it might. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* | aacdec: do not mutate input packet metadatawm42017-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently the demuxer outputs the wrong padding for HE-AAC (based on the raw sample rate, or so). aacdec contains a hack to adjust the muxer padding accordingly before it's used to trim the decoder output. This modified the packet side data, which in combination with the old decoding API would change the packet the user passed to the decoder. This is clearly not allowed, and it breaks running some gapless fate tests with "-fflags +keepside" applied (without keepside, the packet metadata is typically newly allocated, essentially making a copy and not modifying the user's input packet). This should probably be fixed in the demuxer (and consequently also the muxer), but for now only fix the immediate problem. Regression since 946ed78f5f8 (2012).

* | ffmpeg: move subframe warning to libavcodecwm42016-10-01
| | | | | | | | | | | | | | | | | | | | | | With the new decode API, doing this in ffmpeg.c is impractical. There was resistance against removing the warning, so put it into libavcodec. Not bothering with reducing the warning to verbose log level for subsequent wanrings. The warning should be rare, and only happen when developing new codecs for the old API. Includes a change suggested by Michael Niedermayer.

| * lavc: allow asynchronous decoders to return correct pkt_dts valueswm42015-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic code in utils.c sets the AVFrame.pkt_dts field from the packet it was supposedly decoded. This does not have to be true for a fully asynchronous decoder like mmaldec. It could be overwritten with an incorrect value. Even if the decoder doesn't determine the DTS (but sets it to AV_NOPTS_VALUE), it's impossible to determine a correct value in utils.c. Decoders can now be marked with FF_CODEC_CAP_SETS_PKT_DTS, in which case utils.c won't overwrite the field. The decoders are expected to set this field (even if they only set it to AV_NOPTS_VALUE).
