Hi List,<br>
<br>
I'm having trouble getting valid encodes from the ffenc_huffyuv plugin<br>
for one of my two encoding devices. The two devices are a Hauppauge PVR<br>
500 card (which works fine) and an Epiphan VGA2USB capture device (which<br>
does not).<br>
<br>
The pipeline I'm using for the Epiphan card is the following:<br>
<br>
sudo gst-launch -e v4lsrc device=/dev/video2 ! ffmpegcolospace !<br>
ffenc_huffyuv ! avimux ! filesink location=test.avi<br>
<br>
which generates a file like <a href="http://aries.usask.ca/test.avi" target="_blank">http://aries.usask.ca/test.avi</a>. Note that<br>
I've been having trouble getting the files to play on linux, but the<br>
latest version of VLC on windows works.<br>
<br>
If you can't see the contents of that video it's looks like the bottom<br>
1/3 of the video is pieces (~20 pixels high) of the top 2/3 repeated and<br>
color shifted. The odd thing is the other encoders (x264enc,<br>
ffenc_mpeg2video) work fine with this device - it's just the Huffyuv<br>
plugins.<br>
<br>
Does anyone know what's causing this? Or better yet, how to go about<br>
fixing it?</blockquote><div><br>Hi, <br></div><div><br>I can see that the resolution is 1024*768<br>
<br>So try to increase buffer size:<br><br>ffenc_huffyuv buffer-size=2000000<br><br>(default is 524288 using gst-inspect-0.10 ffenc_huffyuv)<br><br>Note that normally, using ffenc_ljpeg the result file has a smaller size. (then use ffedc_ljpeg to decode)<br>

Thanks,<br>
