Jonathan Wright	08b4716a9e	aarch64: Add Armv8.5-A BTI support Add Branch Target Identifiers (BTIs) to all functions defined in AArch64 assembly files. Most of the BTI landing pads are added automatically by the 'function' macro. BTI support is turned on or off at compile time based on the presence of the __ARM_FEATURE_BTI_DEFAULT feature macro. A binary compiled with BTI support can be executed on an Armv8-A processor without BTI support because the instructions are defined in NOP space.

Jonathan Wright	6f04cf54f5	aarch64: Use ret x<n> instead of br x<n> where possible Change AArch64 assembly code to use: ret x<n> instead of: br x<n> "ret x<n>" is already used in a lot of places so this patch makes it consistent across the code base. This does not change behavior or performance. In addition, this change reduces the number of landing pads needed in a subsequent patch to support the Armv8.5-A Branch Target Identification (BTI) security feature.

Anton Khirnov	bd55552d69	ffmpeg: rewrite setting the stream disposition Currently, the code doing this is spread over several places and may behave in unexpected ways. E.g. automatic 'default' marking is only done for streams fed by complex filtergraphs. It is also applied in the order in which the output streams are initialized, which is effectively random. Move processing the dispositions at the end of open_output_file(), when we already have all the necessary information. Apply the automatic default marking only if no explicit -disposition options were supplied by the user, and apply it to the first stream of each type (excluding attached pics) when there is more than one stream of that type and no default markings were copied from the input streams. Explicitly document the new behavior. Changes the results of some tests, where the output file gets a default disposition, while it previously did not.	3 years ago

Marton Balint	406ffd9b9b	avformat/demux: allow total size of packets in raw_packet_buffer to reach probesize Previously this was hardcoded to 2500000 bytes, so probing of the stream codecs was always limited by this, and not probesize.

Marton Balint	0a9edac48e	avfilter/af_apad: do not add infinite silence for zero pad_dur or whole_dur Unfortunately pad_len and pad_dur behaviour was different if 0 was specified, pad_dur handled 0 duration as infinity, for pad_len, infinity was -1. Let's make the behaviour consistent by handling 0 duration for pad_dur and whole_dur as indeed 0 duration. This somewhat changes the behaviour of the filter if 0 was explicitly specified, but deprecating the old option and adding a new for the corrected behaviour seemed a bit overkill. So let's document the change instead. Signed-off-by: Marton Balint <cus@passwd.hu>	3 years ago

Niklas Haas	a943f527a1	lavfi/vf_libplacebo: pick log level dynamically In particular, allows users to go all the way up to PL_LOG_TRACE if desired. (While also avoiding some potentially unnecessary callbacks for filtered messages, including e.g. the CPU cost of printing out shader sources) Response to runtime log level changes by updating it once per filter_frame(), which should hopefully be often enough.	3 years ago
Niklas Haas	51e03409d7	lavfi: add a libplacebo filter This filter conceptually maps the libplacebo `pl_renderer` API into libavfilter, which is a high-level image rendering API designed to work with an RGB pipeline internally. As such, there's no way to avoid e.g. chroma interpolation with this filter, although new versions of libplacebo support outputting back to subsampled YCbCr after processing is done. That being said, `pl_renderer` supports automatic integration of the majority of libplacebo's shaders, ranging from debanding to tone mapping, and also supports loading custom mpv-style user shaders, making this API a natural candidate for getting a lot of functionality out of relatively little code. In the future, I may approach this problem either by rewriting this filter to also support a non-renderer codepath, or by upgrading libplacebo's renderer to support a full YCbCr pipeline. This unfortunately requires a very new version of libplacebo (unreleased at time of writing) for timeline semaphore support. But the amount of boilerplate needed to hack in backwards compatibility would have been very unreasonable.	3 years ago
