Hi all,
I've just updated v4l2-compliance with some important new features.
First of all v4l2-compliance will store the driver state before it
starts testing and it will restore it before the streaming tests
start and when the application exits (including exit due to Ctrl-C).
This makes it possible to setup the driver for the streaming tests
by selecting the right input/output, frequency, format, etc. so that
that will be used by the streaming test.
The current -i, -o and -f options to set the input/output/frequency
have been dropped since they are no longer needed.
Secondly a new option has been added: --stream-all-formats (-f). This
will iterate over all pixelformats, all frame sizes, all frame intervals
and all v4l2_field values and tries to stream 1 second worth of video.
It is normally quite difficult to check if a driver can really handle
all combinations that it advertises, and this option should help.
It uses MMAP streaming or read/write if MMAP streaming is not supported.
Note that only video capture and output devices are supported. No support
for memory-to-memory devices exists currently.
Enjoy!
Hans
