Lynne	f6dd30df24	lavfi/vulkan: split off lavfi-specific code into vulkan_filter.c The issue is that libavfilter depends on libavcodec, and when doing a static build, if libavcodec also includes "libavfilter/vulkan.c", then during link-time, compiling programs will fail as there would be multiple definitions of the same symbols in both libavfilter and libavcodec's object files. Linkers are, however, more permitting if both files that include a common file that's used as a template are one-to-one identical. Hence, to make both files the same in the future, export all avfilter specific functions to a separate file. There is some work in progress to make templated files like this be compiled only once, so this is not a long-term solution. This also removes a macro that could be used to toggle SPIRV compilation capability on #include-time, as this could cause the files to be different.	3 years ago

Andreas Rheinhardt	9181b9ec7c	avutil/hwcontext_qsv: Remove redundant check It has already been checked immediately before that said AVDictionaryEntry exists; checking again is redundant. Furthermore, av_hwdevice_find_type_by_name() requires its argument to be non-NULL, so adding a codepath that automatically calls it with that parameter is nonsense. The same goes for the argument corresponding to %s. Fixes Coverity issue 1491394. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Derek Buitenhuis	a35101aae3	avformat/http: Add short_seek_size option In `45bfe8b838`, short_seek_threshold was removed from the public AVIO struct. Although this option was private and not intended to be used by public API users, it was nonetheless, because it provided functionality that could otherwise not be gained via public API. This was especially important for networked I/O like HTTP, where the internal size for lavf could be way to small depending on the specifics of a user's usecase, such as reading interlavd media files from cloud storage. Add an AVOption to make this functionality accessible to the HTTP client. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	3 years ago

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.

This does not change behavior or performance.

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	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
