AJA Output Filter 0.2.3

AJA Output Filter - Send frame of any source to AJA output

This is a simple plugin that provides a filter to send video to AJA output.

The idea is inspired by Decklink Output Filter and majority of the code is copied from this plugin.

Hi, right now this plugin immediately grabs my AJA card on startup which prevents other programs from using it. I routinely use Unreal Engine for Virtual production which reads video from my AJA card, then I use OBS to screen-record for tutorials. Can't do that with this plugin enabled.

Also, I have a AJA Kona-HDMI which is input-only, so since this is an output filter it shouldn't even try to open that particular card.

A work around seems to be to take the "aja" plugin files out of the obs plugins folder. Though I assume they will come back if I get an OBS update.

It would be nice if there was a simple "off" switch for the plugin, or if it just didn't attempt to access the card till you startup the filter.

When you disable the filter (by clicking eye icon in the list named "Effect Filters". Isn't this sufficient for your case?

If you remove this filter ("obs-aja-output-filter.so") and still you have the problem, the problem should be asked on the support channel of OBS Studio (Discord server or the forums).

Is the device listed in "AJA I/O Device Output" from the Tool menu as well? If listed, it should be reported to obs-studio. This plugin just reuse the same property as the AJA I/O Device Output so that I guess the list should be same.

Maybe, it might be a possibility to have a checkbox to autostart, start and stop buttons.
