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.

2016-08-12avcodec/utils: only warn when passed invalid lowres valueAman Gupta
This makes it easier to use the lowres option when dealing with input files in different codecs. If the codec doesn't support lowres=1 for instance, it will throw a warning and use lowres=0 instead of erroring out completely. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-06-21lavc: export the timestamps when decoding in AVFrame.ptsAnton Khirnov
Currently it's exported as AVFrame.pkt_pts, which is also the only use for that field. The reason it is done like this is that lavc used to export various codec-specific "timing" information in AVFrame.pts, which is not done anymore. Since it is confusing to the callers to have a separate field which is used only for decoder timestamps and nothing else, deprecate pkt_pts and use just AVFrame.pts everywhere.

2016-04-29avcodec/utils: split side-data in new decode API toowm4
The deprecated avcodec_decode_video2() and avcodec_decode_audio4() functions called av_packet_split_side_data() on the input packets. This is required for packets produced by libavformat with the AVFMT_FLAG_KEEP_SIDE_DATA flag unset (which is unfortunately the default). The new API didn't do this yet, although it didn't matter as no decoder supports the new API yet. The emulation layer for the old API calls the old API functions, which took care of the splitting. Add this code to the new API codec entrypoints too, because we shouldn't send essentially corrupted data to decoders.

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>
