Hi all.
I need to mask a v4l2 stream with a png image.
I do that applying gdkpixbufoverlay before final imxv4l2sink, but the
stream is very slow and a lot of frames are lost.ù
There is way to mask the stream using IPU or other hardware processor?
The board is equiped with imx6dl
This is the actual pipeline
#!/bin/sh
gst-launch-1.0 imxv4l2src device=/dev/video0 \
! capsfilter caps="video/x-raw, width=640, height=480" \
! imxvideoconvert_g2d rotation=4 \
! gdkpixbufoverlay location=mask.png \
! imxv4l2sink overlay-width=800 overlay-height=600
overlay-left=235 overlay-top=65 enable-last-sample=true name=sink
Best regards,
MZ
