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 &
