The following options can be configured in the CARMA Configuration Admin. For more detailed information on the configuration admin, please see our CARMA Configuration Admin wiki article.
Convert
Enter the file system path to ImageMagick. If your image thumbnails
aren't being correctly generated, this path is most likely wrong. Ask your server host for the correct path.
MPlayer
Enter the file system path to MPlayer. If your video thumbnails
aren't being properly generated, this path is probably wrong. Ask your server host for the correct path.
ENABLE_ERROR_POSTS
Sets errors on your server to post to our support server. If we see anything
worrisome, we will notify you.
NO_BFRAMES_CHECK
You must check this option in order to use recent versions of MPlayer. If you
have a problem or get an error creating Flash content, please try changing this setting. If it is enabled, try disabling it; if it is disabled, try enabling it.
You can run the following test to determine whether you need to enable
or disable the NO_BFRAMES_CHECK setting.
/usr/bin/mencoder 'input-file' -o 'output-file' -quiet -of lavf -oac mp3lame -lameopts abr:br=36 -ovc lavc -vf scale=480:360 -lavcopts vcodec=flv:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:vbitrate=1500 -ofps 15 -srate 44100
Replace input-file in the example above with the filename of your source video. Replace
output-file in the example above with the filename of the Flash movie being outputted. Your output will look similar to the following example:

** MUXER_LAVF *****************************************************************
If you wish to use libavformat muxing, you must ensure that your video stream
does not contain B frames (out of order decoding) and specify:
-lavfopts i_certify_that_my_video_stream_does_not_use_b_frames
on the command line.
REMEMBER: MEncoder's libavformat muxing is presently broken and will generate
INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!
*******************************************************************************
If you get an error message containing "-lavfopts i_certify_that_my_video_stream_does_not_use_b_frames",
then you need to disable the NO_BFRAMES_CHECK configuration option. If you don't get the
message, enable NO_BFRAMES_CHECK.
TOUR_ALL_VIDEOS
Enable TOUR_ALL_VIDEOS to show all available videos on tours. Disabling the TOUR_ALL_VIDEOS configuration option hides all videos during site tours, unless the video was specifically marked as a tour video.
