Howdy, I'm trying to play video games through my PVR-150 and I'm finding the lag due to the encoder (while only about 0.9s) to be unbearable.<br><br>I've been trying to figure out how to get this card in to "Live Preview" mode in Linux. Hauppauge includes some instructions on their site for how to do this in Windows.. But of course, that doesn't help me a much.<br>
<br>When I check the available output formats, I get the following:<br><br><div style="margin-left: 80px;">j@Neptune:~$ v4l2-ctl --list-formats<br>ioctl: VIDIOC_ENUM_FMT<br> Index : 0<br> Type : Video Capture<br>
Pixel Format: 'HM12'<br> Name : HM12 (YUV 4:2:0)<br><br> Index : 1<br> Type : Video Capture<br> Pixel Format: 'MPEG' (compressed)<br> Name : MPEG<br></div><br>
So then I try to change the output video format from MPEG to HM12 (hoping that is less laggy). The operation returns as though it worked, except when I check the settings is doesn't seem to notice the new "pixel format"..<br>
<br>I run the below to change the format:<br><br><div style="margin-left: 80px;">j@Neptune:~$ v4l2-ctl -V<br>Format Video Capture:<br> Width/Height : 720/450<br> Pixel Format : 'MPEG'<br> Field : Interlaced<br>
Bytes per Line: 0<br> Size Image : 131072<br> Colorspace : Broadcast NTSC/PAL (SMPTE170M/ITU601)<br></div><br><br><br> Immediately after that I, attempt to change the format with "j@Neptune:~$ sudo v4l2-ctl --set-fmt-video=width=720,height=480,pixelformat=0", but I get the following (with no error messages):<br>
<div style="margin-left: 80px;">j@Neptune:~$ v4l2-ctl -V<br>Format Video Capture:<br> Width/Height : 720/480<br> Pixel Format : 'MPEG'<br> Field : Interlaced<br> Bytes per Line: 0<br> Size Image : 131072<br>
Colorspace : Broadcast NTSC/PAL (SMPTE170M/ITU601)<br></div><br>This nothing changed.<br><br><br>Please help me figure out how to watch the video content hitting my PVR-150 in as close to real time as possible!!<br>
