* | avcodec: consider an error during decoder draining as EOFwm42017-03-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no reason that draining couldn't return an error or two. But some decoders don't handle this very well, and might always return an error. This can lead to API users getting into an infinite loop and burning CPU, because no progress is made and EOF is never returned. In fact, ffmpeg.c contains a hack against such a case. It is made unnecessary with this commit, and removed with the next one. (This particular error case seems to have been fixed since the hack was added, though.) This might lose frames if decoding returns errors during draining.

| | | | | | | | | | | | | | | | | | | | | | | | | | The assumption that avcodec_send_packet makes regarding decoders consuming the entire packet is not true if the codec supports truncated decoding mode and the truncated flag is turned on.

| * lavc: export the timestamps when decoding in AVFrame.ptsAnton Khirnov2016-06-211-0/+10
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | 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: introduce a new decoding/encoding API with decoupled input/outputwm42016-03-231-2/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | avcodec/utils: split side-data in new decode API toowm42016-04-291-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
