| | | | | | | | | | Also, add generic code for handling cropping, so the decoders can export just the cropping size and not bother with the rest.
| * pthread_frame: do not run hwaccel decoding asynchronously unless it's safeAnton Khirnov2016-12-19
| | | | | | | | | | | | | | | | | | | | Certain hardware decoding APIs are not guaranteed to be thread-safe, so having the user access decoded hardware surfaces while the decoder is running in another thread can cause failures (this is mainly known to happen with DXVA2). For such hwaccels, only allow the decoding thread to run while the user is inside a lavc decode call (avcodec_send_packet/receive_frame).

| * 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.

* | avcodec, avformat: deprecate anything related to side data mergingwm42017-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deprecates anything that has to do with merging/splitting side data. Automatic side data merging (and splitting), as well as all API symbols involved in it, are removed completely. Two FF_API_ defines are dedicated to deprecating API symbols related to this: FF_API_MERGE_SD_API removes av_packet_split/merge_side_data in libavcodec, and FF_API_LAVF_KEEPSIDE_FLAG deprecates AVFMT_FLAG_KEEP_SIDE_DATA in libavformat. Since it was claimed that changing the default from merging side data to not doing it is an ABI change, there are two additional FF_API_ defines, which stop using the side data merging/splitting by default (and remove any code in avformat/avcodec doing this): FF_API_MERGE_SD in libavcodec, and FF_API_LAVF_MERGE_SD in libavformat. It is very much intended that FF_API_MERGE_SD and FF_API_LAVF_MERGE_SD are quickly defined to 0 in the next ABI bump, while the API symbols are retained for a longer time for the sake of compatibility. AVFMT_FLAG_KEEP_SIDE_DATA will (very much intentionally) do nothing for most of the time it will still be defined. Keep in mind that no code exists that actually tries to unset this flag for any reason, nor does such code need to exist. Code setting this flag explicitly will work as before. Thus it's ok for AVFMT_FLAG_KEEP_SIDE_DATA to do nothing once side data merging has been removed from libavformat. In order to avoid that anyone in the future does this incorrectly, here is a small guide how to update the internal code on bumps: - next ABI bump (probably soon): - define FF_API_LAVF_MERGE_SD to 0, and remove all code covered by it - define FF_API_MERGE_SD to 0, and remove all code covered by it - next API bump (typically two years in the future or so): - define FF_API_LAVF_KEEPSIDE_FLAG to 0, and remove all code covered by it - define FF_API_MERGE_SD_API to 0, and remove all code covered by it This forces anyone who actually wants packet side data to temporarily use deprecated API to get it all. If you ask me, this is batshit fucked up crazy, but it's how we roll. Making AVFMT_FLAG_KEEP_SIDE_DATA to be set by default was rejected as an ABI change, so I'm going all the way to get rid of this once and for all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it clear that there is no timing-dependent behavior. In particular, there is no state in which both input and output are denied, and where you have to wait for a while yourself to make progress (apparently some hardware decoders like to do this). Avoid wording that makes references to time. It shouldn't be mistaken for some kind of asynchronous API (like POSIX read() can return EAGAIN if there is no new input yet). It's a state machine, so try to use appropriate terms. Signed-off-by: Diego Biurrun <diego@biurrun.de> Merges Libav commit 8a60bba0ae.
