[gst-devel] Huffyuv encoding problems

Hi List,

I'm having trouble getting valid encodes from the ffenc_huffyuv plugin 
for one of my two encoding devices.  The two devices are a Hauppauge PVR 
500 card (which works fine) and an Epiphan VGA2USB capture device (which 
does not).

The pipeline I'm using for the Epiphan card is the following:

sudo gst-launch -e v4lsrc device=/dev/video2 ! ffmpegcolospace ! 
ffenc_huffyuv ! avimux ! filesink location=test.avi

which generates a file like http://aries.usask.ca/test.avi.  Note that 
I've been having trouble getting the files to play on linux, but the 
latest version of VLC on windows works.

If you can't see the contents of that video it's looks like the bottom 
1/3 of the video is pieces (~20 pixels high) of the top 2/3 repeated and 
color shifted.  The odd thing is the other encoders (x264enc, 
ffenc_mpeg2video) work fine with this device - it's just the Huffyuv 
plugins.

Does anyone know what's causing this?  Or better yet, how to go about 
fixing it?

Thanks,
G
