hello,
i made a small change to plugins/videoV4L2 in order to expose channel, frequency, norm, width and height parameters to pd so now i can switch between tuner and other inputs on my USB video digitizer
this is in my github repos for now, feel free to merge it https://github.com/avilleret/Gem.git on branch videoV4L2 and commit c250e441ac9c3b3796d09dc94d60e2d423f9b005
hope this helps
a.
