Hello,

 

I'm not an expert, so thank you for being patient with me.

 

I am working on using gstreamer on an IMX6 quad core processor to output some video with an image overlay. (3.0.35 Kernel, Yocto OpenEmbedded)

 

It is working great, except that I would like to change how much transparency exists.

 

I keep seeing a variable in other posts, VSALPHA=1 .  Can anyone shed some light, or point me to some documentation, as to how this is used with Gstreamer?

 

Here are my gstreamer lines:

gst-launch tvsrc device=/dev/video0 ! mfw_v4lsink disp-width=1279 disp-height=720 device=/dev/video17 &

 

gst-launch filesrc location=/home/root/tlogo.png ! pngdec ! imagefreeze ! ffmpegcolorspace ! fbdevsink device=/dev/fb0 &

 

Thank you,

Ryan
