[SOLVED] Live Video Capture Image Problems
SOLVED: I reduced VLC's latency by going to preferences, choosing the non-simplifed preferences, going to Input / Codecs, scrolling down to the bottom in the "Advanced" section, and lowering the "Live capture caching" which was on 300.
So I set up my capture card (finally) and I have /dev/video0. I've tried to view the stream with three different viewers, each of which has their own problems.
Each viewer and its problem(s):
VLC: has the best image quality, but has noticable latency (about 1 second, I want the latency to be relatively unnoticable.)
MPlayer: has decent latency, but the image staggers and flickers.
tvtime: has the best latency of them all, but has the worse image of them all: the image is green and magenta AND staggers and flickers.
How I'm currently using each viewer:
VLC: open capture device and choosing /dev/video0
mplayer: mplayer tv:// -tv driver=v4l2:norm=NTSC:width=720:height=480:outfmt=uyvy:device=/dev/video0:input=0
tvtime: just opening it. But I've looked through the in-program menus to see if I could find anything.
Possible solutions:
Lower VLC's latency.
Make MPlayer's image not stagger.
Make tvtime's image not stagger and the colors not be distorted.
So any of those would solve my issue, but I can't figure out how to do any of them...
I think the image staggering is caused by the capture card being not of very good quality... but I think VLC just handles those bad frames better... I think.. I don't really know.
I'm using nouveau, if that has anything to do with it, and my capture card is an "easycap" of this variety: http://www.linuxtv.org/wiki/index.php/S … re_devices
