How to enable sound and widescreen resolution using v4l2loopback devices and mp4 files

[Diego Silva]

When i use:

gst-launch -v filesrc location=sample.mp4 ! decodebin ! ffmpegcolorspace !
v4l2sink device=/dev/video0

The video output nas tv resolution and no sound. How can i fix that?

Also, how must i send mp4 files via rtp/usp?

Thanks,

Diego Silva
