2022-03-17v4l2-ctl: allow waiting/polling for multiple eventsHans Verkuil1-91/+76
Currently there can be only one --wait/poll/epoll-for-event option, so waiting or polling is for a single event only. Add support for more than one of these options to make it possible to wait/poll for multiple events. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

2021-11-25v4l-utils: use v4l_getsubopt instead of getsuboptHans Verkuil5-5/+6
Android doesn't have getsubopt at all, and some libc implementations use a getsubopt variant that behaves slightly different. So add a new v4l-getsubopt.h header that either just uses the glibc function (if glibc is detected) or uses a static inline v4l_getsubopt that is copied from glibc. This should avoid such problems.

2021-08-04v4l2-ctl: fix bugs found in streaming_set_cap2outDafna Hirschfeld1-1/+15
When exporting buffers from a capture device to an output device. There are several bugs: 1. The bytesused are set from the exported buffer, the value might be bigger than the length of the output buffer. 2. The file descriptor field 'm.fd' in 'struct v4l2_buffer' is not set. This patch fix those issues.
