2016-10-01ffmpeg: move subframe warning to libavcodecwm4
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.

2016-04-21lavc: introduce a new decoding/encoding API with decoupled input/outputwm4
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. From Libav commit 05f66706d182eb0c36af54d72614bf4c33e957a9. Signed-off-by: Anton Khirnov <anton@khirnov.net>

2015-09-12lavc: allow asynchronous decoders to return correct pkt_dts valueswm4
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).
