test-source: add test source class

2022-11-22T16:02:25+00:00

The test_source class is an implementation of the video_source class
that generates a test pattern in userspace to provide video. We have
some operations which are implemented as no-ops. To quiet the
compiler warnings this causes, flag their arguments as unused.

video-source: add fill_buffer

2022-11-22T16:02:25+00:00

We are preparing to allow video sources whose data is generated in
userspace. To this end, add a fill_buffer function to video_source.

meson: Convert CMake to Meson build infrastructure

2022-11-22T12:31:14+00:00

Provide infrastructure to be able to build the uvc-gadget library as a
shared object and an executable which links against this as a dependency
to implment the reference 'uvc-gadget' application.

All existing cmake infrastructure is removed. This removes custom glob
support that was previously used by an early development for Android,
which is expected to be re-added later when required.

stream, uvc: add uvc_stream_set_frame_rate

2019-02-06T06:49:31+00:00

We would like to be able to set the frame rate of the video source of a
stream. This patch adds such a function to set the source's frame rate
from the stream. The frame rate is set right after the format is set.

video-source: add video_source_set_frame_rate

2019-02-06T06:49:24+00:00

We would like to be able to set the frame rate for video sources. This
patch adds a set_frame_rate op for video sources, along with a wrapper
to call video sources' set_frame_rate functions.

lib: Compile custom glob() implementation for Android

2018-07-31T12:56:48+00:00

The Android C library doesn't provide the glob() function which we use
in the configfs code. Add conditional compilation to cmake such that a
local copy of glob is automatically compiled if glob isn't provided.

lib: glob: Fix compilation on Android

2018-07-31T12:56:48+00:00

The glibc glob() implementation doesn't compile on Android due to
missing support for getlogin_r (before Android ABI 28) and to missing
__THROW, __THROWNL and __attribute_noinline__ macros.

getlogin_r is only used to implement support for the '~' path component
which we don't use in the uvc-gadget library, so we can compile it out.
The three macros can safely be defined as no-op.

lib: Import glob.c from glibc 2.26

2018-07-31T12:56:48+00:00

The Android libc implementation (bionic) doesn't provide the glob()
function. To enable compilation of the UVC gadget library for Android,
import the glibc glob() implementation.

The glob.c and glob.h files are imported unmodified to ease copyright
management, even if they don't compile as-is. Compilation will be fixed
separately.
