* | avcodec/crystalhd: Adapt to new new decode APIPhilip Langdale2017-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The new new decode API requires the decoder to ask for the next input packet, and it cannot just return EAGAIN if that packet cannot be processed yet. This means we must finally confront how we get this decoder to block when the input buffer is full and no output frames are ready yet. In the end, that isn't too hard to achieve - the main trick seems to be that you have to aggressively poll the hardware - it doesn't seem to make any forward progress if you sleep.

| * 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.

|\| | | | | | | | | | | | | | | | | | | * commit '549d0bdca53af7a6e0c612ab4b03baecf3a5878f': decode: be more explicit about storing the last packet properties Also copy pkt->size in extract_packet_props(), as it's needed for AVFrame.pkt_size Merged-by: James Almer <jamrial@gmail.com>
| * 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.
* | libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1Aaron Levinson2017-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1. This is only relevant when thread.h is included by C++ files. In this case, the relevant code is only defined if HAVE_PTHREADS is defined as 1. Use configure --assert-level=2 to do so. Note: Issue discovered as a result of Coverity build failure. Cause of build failure pinpointed by Hendrik Leppkes. Comments: -- libavutil/thread.h: Altered ASSERT_PTHREAD_NORET definition such that it uses av_make_error_string instead of av_err2str(). av_err2str() uses a "parenthesized type followed by an initializer list", which is apparently not valid C++. This issue started occurring because thread.h is now included by the DeckLink C++ files. The alteration does the equivalent of what av_err2str() does, but instead declares the character buffer as a local variable. Signed-off-by: Marton Balint <cus@passwd.hu>
