* mpegvideo_enc: Fix encoding videos with less frames than the delay of the ↵Alexis Ballier2015-10-25
| | | | | | | | | | | | encoder When the encoder is fed with less frames than its delay, the picture list looks like { NULL, NULL, ..., frame, frame, frame }. When flushing the encoder (input frame == NULL), we need to ensure the picture list is shifted enough so that we do not return an empty packet, which would mean the encoder has finished, while it has not encoded any frame.

* lavc: Deprecate AVPicture structure and related functionsVittorio Giovara2015-10-22
| | | | | | | | | | | | | | | | | This structure served as a bridge between data pointers and frames, but it suffers from several limitations: - it is not refcounted and data must be copied to every time - it cannot be expanded without ABI break due to being used on the stack - its functions are just wrappers to imgutils which add a layer of unneeded indirection, and maintenance burden - it allows hacks like embedding uncompressed data in packets - its use is often confusing to our users AVFrame provides a much better API, and, if a full blown frame is not needed, it is just as simple and more straightfoward to use data and linesize arrays directly.

* lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* libschroedinger: Properly use AVFrame APIVittorio Giovara2015-10-14

* mmaldec: be more tolerant against MMAL not returning decoded outputwm42015-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | In some situations, MMAL won't return a decoded frame for certain input frames. This can happen if a frame fails to decode, or if a packet does not actually contain a complete frame. In these situations, we would deadlock (or actually timeout) waiting for an expected output frame, which is not ideal. On the other hand, there are situations where we definitely have to block to avoid deadlocks. (This mess is a consequence of trying to map MMAL's asynchronous and flexible dataflow to libavcodec, which is more static and rigid.) Solve this by doing a blocking wait only if the amount of buffered data is too big. The whole purpose of the blocking wait is to avoid excessive buffering of input data, so we can skip it if it appears to be low. The consequence is that libavcodec can gracefully return no frame to the API user. We want to track the number of full packets to make our heuristic work. But MMAL buffers are fixed-size, requiring splitting large packets. This is why the previous commit is needed. We use the ..._FRAME_END flag to remember packet boundaries, but MMAL does not preserve these buffer flags when returning buffers to the user. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mmaldec: refactor to have more context per MMAL input bufferwm42015-10-04
| | | | | | | | | | | | | | The next commit needs 1 bit of additional information per MMAL buffer sent to the MMAL input port. This information will be needed when the buffer is recycled (i.e. returned by the input port's callback). Normally, we could use MMAL_BUFFER_HEADER_FLAG_USER0, but that is unexpectedly not preserved. Do this by storing a pointer to FFBufferEntry in the MMAL buffer's user data, instead of an AVBufferRef. This also changes the lifetime of FFBufferEntry.
