mencoder settings help
 
i have a tv tuner card connected to a cctv camera for streaming, all works good in tvtime, cheese used to work but then i changed the resolution to a lower one and now it segfaults, purged reinstalled same issue, also i tried with mplayer,mencoder,mythtv(coludnt find any signal on the input),and camorama
Code:

mplayer tv:// -tv driver=v4l2:input=1:channel=1:width=768:height=768:device=/dev/video0
and it displays lines through everything but i can see the messed up image, i believe this is due to the current input format being YVU420, i was able in another program to verify this by changing the input codec to yvuv i think it was, how do i change the in mplayer,mencoder,camorama has this bug too, so if anyone can help on how to change this setting ut codec in mplayer and mencoder, also canorama has this issue, but i can actually see everything, b/w and with lines through it, if anyone can help me with this would be appreciated.really im just trying to record video to avi

5.1. The video is sluggish/has a slow response. What can I do?


You may have set "ximagesink" ("X Window System (No Xv)") as video-output.
This means, that your cpu is doing all the work. Change it to "xvimagesink"
("X Window System (X11/XShm/Xv)") in order to let your graphics card do the work.



To change the settings, run "gstreamer-properties", click the Video tab
and change the appropriate settings.

5.2. I have a Mac with iSight and a ATI graphics card, and the colors are weird.


This is a problem with the ATI graphics card, though there is a work around.
Change the video-output to custom and insert the following: "ffmpegcolorspace !
video/x-raw-yuv,format=(fourcc)YV12 ! ffmpegcolorspace ! xvimagesink".



To change the settings, run "gstreamer-properties", click the Video tab
and select custom from the drop down menu.

5.3. My webcam works with gstreamer, but does not work with Cheese. What's wrong?


Using "gstreamer-properties" mentioned in the above question, try changing from
xvimagesink to ximagesink or vice-versa. If this still does not work run "cheese --verbose" on
the command line and copy the logging into a bug report in our

bug tracker.

5.4. My webcam works with other programs such as Ekiga, Camorama, but not with Cheese. What's wrong?


See if your webcam works when testing it in "gstreamer-properties". If it works
there, but not in Cheese, please file a bug report in our

bug tracker.

5.5. Where does Cheese store my photos?


Your photos are stored in ~/.gnome2/cheese/media. You can also save
them to an alternate location from within Cheese. Please see the help
topic titled "Saving photos and videos to an alternate location" for
information on this.

5.6. My Quickcam Express doesn't work with Cheese...


or gstreamer, and I see errors like "Not enough buffers. We got 1, we
want at least 2" in the Cheese output. With driver "qc-usb".



Try running "qcset /dev/video0 compat=dblbuf" to enable double buffer
compatibility mode, then restart Cheese

5.7. Which cameras are supported


Cheese uses gstreamer for video grabbing. So in principle Cheese supports
any camera that works with GStreamer. In principle that should be any camera
which support video4linux or video4linux2.




good luck
