glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and _SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE where the latter two are used to be forwards-compatible and avoid warnings about the use of deprecated definitions.

Do not use skip_remaining() to fully wipe the cache, as this could do a 64-bit shift of a 64-bit variable which is undefined behavior in C. Instead set the related variables to zero directly. Thanks to Uoti for pointing out the problem. CC: libav-stable@libav.org

This works around type aliasing violations and related warnings. Also add some missing error checking.

Avoid anonymously typedeffed structs and enums, drop an unused context member, fix a small wording mishap, sizeof(type) ---> sizeof(*variable), drop a needlessly verbose log message, use av_malloc_array() where appropriate.

version 2013-02-08 Rl - fixes/optimization in multistrip encoding and codebook size choice, quality/bitrate is now better than that of the binary proprietary encoder version 2013-02-12 Rl - separated codebook training sets, avoided the transfer of wasted bytes, which yields both better quality and smaller files - now using the correct colorspace (TODO: move conversion to libswscale) version 2013-02-14 Rl "Valentine's Day" version: - made strip division more robust - minimized bruteforcing the number of strips, (costs some R/D but speeds up compession a lot), the heuristic assumption is that score as a function of the number of strips has one wide minimum which moves slowly, of course not fully true - simplified codebook generation, the old code was meant for other optimizations than we actually do - optimized the codebook generation / error estimation for MODE_MC version 2013-04-28 Rl - bugfixed codebook optimization logic version 2014-01-20 Rl - made the encoder compatible with vintage decoders and added some yet unused code for possible future incremental codebook updates - fixed a small memory leak version 2014-01-21 Rl - believe it or not, now we get even smaller files, with better quality (which means I missed an optimization earlier :) Signed-off-by: Diego Biurrun <diego@biurrun.de>

If using the winstore compat library, a fallback LoadLibrary function does exist, that only calls LoadPackagedLibrary though (which doesn't work for dynamically loading d3d11 DLLs). Therefore explicitly check the targeted API family instead. Make this check a reusable HAVE_* component which other parts of the libraries can check when necessary as well.

Currently, the tags enforced and set on the segmenter muxer level mismatch what the mp4/ismv muxer uses (since 713efb2c). Skip the codec_tag altogether here, to let the user (try to) set whichever codec/tag is preferred; the individual chained muxer will reject invalid codecs anyway.

The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

This fixes a segfault (originally found in Movian, but traced to libav) when decoding subtitles because only an array of rects is allocated, but not the actual structs it contains. The issue was probably introduced in commit 23833236 where the loop to allocate the rects in the array was thrown away. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

Hardware accelerated decoding generally uses AVHWFramesContext for pool allocation of hardware surfaces. These are setup to allocate surfaces aligned to hardware and hwaccel API requirements. Due to the architecture, av_hwframe_get_buffer() will return AVFrames with the dimensions set to the aligned sizes. This causes some decoders (like hevc) return these aligned size as final frame size, instead of cropping them to the video's actual dimensions. To make sure this doesn't happen, crop the frame to the size the decoder expects when ff_get_buffer() is called. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

Some devices (some phones, apparently) will support only this opaque format. Of course this won't work with CLI, because copying data directly is not supported. Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does not support this mode, even if it's the only supported mode. But since opaque surfaces are generally less useful, that's probably ok. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

Some existed since forever, some are new. The cast in get_surface() is silly, but unless we change the av_log function signature, or all callers of ff_dxva2_get_surface_index(), it's needed to remove the const warning. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

Make supported codec profiles part of each dxva_modes entry. Every DXVA2 mode is representative for a codec with a subset of supported profiles, so reflecting that in dxva_modes seems appropriate. In practice, this will more strictly check MPEG2 profiles, will stop relying on the surface format checks for selecting the correct HEVC profile, and remove the verbose messages for mismatching H264/HEVC profiles. Instead of the latter, it will now print the more nebulous "No decoder device for codec found" verbose message. This also respects AV_HWACCEL_FLAG_ALLOW_PROFILE_MISMATCH. Move the Main10 HEVC entry before the normal one to make this work better. Originally inspired by VLC's code. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

These variables might be set from a previous probe run, but one or the other program that is probed for may not grok the flags, resulting in errors during assembling when the values of those variables are passed to the assembler.

The previous default sets the allocated surfaces to 32 unless it is user-overridden or the lookahead parameter is set. Change the surfaces calculation for default, B-frames and lookahead scenario.

Previously, if a session allocates x surfaces, only x-1 surfaces are used (due to combination of output delay and lock toggle logic).

The rtmp protocol uses nonblocking reads, to poll for incoming messages from the server while publishing a stream. Prior to 94599a6d and d13b124e, the tls protocol handled the nonblocking flag, mostly as a side effect from not using custom IO callbacks for reading from the socket. When custom IO callbacks were taken into use in d15eec4d, the handling of a nonblocking socket wasn't necessary for the default blocking mode any longer. The code was simplified, since it was overlooked that other code within libavformat actually used the tls protocol in nonblocking mode. This fixes publishing over rtmps, with the gnutls backend.
