error "no element "video"" when input is yuv

[alan wang]

Hello Claire

What's your purpose here ? You want just play a yuv raw frames or encode
yuv frames.

If you want to play yuv raw frames with gstreamer. You need command line
like:

gst-launch-1.0 filesrc location=/home/user/Videos/out.yuv ! videoparse
width=1920 height=816 framerate=24/1 format=2 ! autovideoconvert !
autovideosink

If you want to encoder raw frames, you need command line like:

gst-launch-1.0 filesrc location=test_240X135.yuv blocksize=64800 !
video/x-raw, format=YUY2,width=240,height=135,framerate=25/1 !
omxmjpegvideoenc ! avimux ! queue ! filesink location=240x135_2.avi
