[gst-devel] how to use gst-launch for playing yuv video files without any header?

[Nikhil Raveendranathan]

Hi,

This is what I had used:
gst-launch filesrc location=test.yuv ! xvimagesink

And in the program that I wrote, I linked filesrc, capsfilter and
xvimagesink. Setting caps of capsfilter according to the properties of the
yuv video file.

Can you mention the gst-launch command that you had used for the same?

Regards,
Nikhil

Yes, I've done that.

What is the actual gst-launch command you tried to run?
