Hi,
capturing from analog cards Terratec Cinergy 400 TV and Terratec Cinergy
XS USB isn't possible in ffmpeg versions from 0.7.13 to 0.11.1. The
cards are proved OK for Linux and working with all of my other apps
(tvtime, xawtv, mplayer, mencoder). See my discussion on linux-media
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/51055
I'm using Fedora 17 and tried different versions from 0.5.x wih
different hardware. The cards were tuned to Channel E10 (europe-west)
and had good quality signal (analog cable).
The test results are
Cinergy XS USB Cinergy 400 TV
0.5.10 OK OK
0.7.13 OK broken (differently, s.b.)
0.8.12 OK broken (differently, s.b.)
0.9.2 OK broken (differently, s.b.)
0.9.2 (--enable-libv4l2) OK broken (like in subject)
0.10.4 (--enable-libv4l2) OK broken (like in subject)
0.11.1 OK broken (differently, s.b.)
0.11.1 (--enable-libv4l2) OK broken (like in subject)
The detailed error from the broken test cases are below. Is something
wrong with my command line?
Thanks in advance
