Ready-To-Fly video capture issues
Hi,
I'm working with RTF drone with RealSense R200 and I'm trying to capture video stream.
When I type command on my drone:
sh-4.3# gst-launch-1.0 v4l2src device=/dev/video13 ! video/x-raw, width=640, height=480, framerate=30/1 ! xvimagesink
I get video stream in uppel left corner of my screen.
But when I try to save the stream using this command:
sh-4.3# gst-launch-1.0 v4l2src device=/dev/video13 ! video/x-raw, width=640, height=480, framerate=30/1 ! filesink location=video13.mp4
and try to open it (after copying onto my computer) via VLC media player, it doesn't work.
So I tried capturing images with this command:
sh-4.3# C=10 INPUT=1 MODE=PREVIEW /home/root/sample-apps/capturev4l2/capturev4l2 --userp -d /dev/video13
Then I copied output files onto my computer and tried to convert them with ffmpeg with command:
my-linux> ffmpeg -f rawvideo -s 640x480 -pix_fmt yuv420p -i Image-video2-620x480-7.yuv420 test.jpg
I get this output:

I also tried using website "rawpixels.net" to convert file, but it didn't work.
My intel aero version is 1.6.0
How can I get converted file (image and video)?
