The one thing you<br></pre><pre>can try is to set an environment variable for specific clients like the following and hope it uses that specific Cinelerra_rc <br> CIN_CONFIG="/pathname>/<filename_such_as_.bcast5>" {path}cin -d port#<br></pre><pre>where that specific Cinelerra_rc has "USE_HW_DEV=vdpau" or "USE_HW_DEV=vaapi" appropriately.<br></pre><pre>Alternatively, an environment variable can be set and tried.
