Streaming webcam to .ts file: link error

[Dystroxic]

Hello,

I have a webcam, and I'm trying to use gstreamer to stream the audio and
video to a .ts fifo file. This is the info for the webcam:

Driver Info (not using libv4l2):

	Pixel Aspect: 1/1
Streaming Parameters Video Capture:
	Capabilities     : timeperframe
	Frames per second: 20.000 (20/1)
	Read buffers     : 0
                     brightness (int)    : min=-64 max=64 step=1 default=0
value=0
                       contrast (int)    : min=0 max=64 step=1 default=32
value=32
                     saturation (int)    : min=1 max=128 step=1 default=64

                            hue (int)    : min=-40 max=40 step=1 default=0

                          gamma (int)    : min=72 max=500 step=1 default=100
value=100
                           gain (int)    : min=0 max=100 step=1 default=0

           power_line_frequency (menu)   : min=0 max=2 default=1 value=1
                      sharpness (int)    : min=0 max=6 step=1 default=2
value=2
         backlight_compensation (int)    : min=0 max=2 step=1 default=1
value=1


So from this, we see that it's using YUYV format. So then I try to run this
command:

gst-launch-1.0 -e -v v4l2src device="/dev/video0" !
'video/x-raw,format=YUYV,framerate=25/1,width=640,height=360' ! x264enc
bitrate=498 ! mpegtsmux ! filesink location=video1.ts

But it gives the error:

WARNING: erroneous pipeline: could not link v4l2src0 to x264enc0

And I cannot figure out why I can't get this to work. I also tried "YUY2"
for the format field (based on  this chart
<http://wiki.oz9aec.net/index.php/Pixel_formats>  ), and also tried having
(fourcc) in the format based on the same chart, but that threw a parsing
error.

Any thoughts on how I can get this camera to stream to the file?
