Hi Everyone, I discovered a bug that has come back in 1.3 that was originally solved in 1.0 and was fine until 1.2. You will see this bug if you are running the reference capture agent, have set your Epiphan VGA2USB type to be a V4LSRC and have set the framerate to 10 (in your /opt/matterhorn/felix/conf/services/org.opencastproject.capture.impl.ConfigurationManager.properties file you set the properties capture.device.vga.type=V4LSRC and capture.device.vga.framerate=10 for example). These settings are the most common if you are using a scaler to control the input and don't want to use the special pipeline we have designed to handle resolution and disconnection of sources.
If you are suffering from this bug, all of the captures from the capture agent once ingested will end in failure complaining that it failed to mux audio and a vga source together in the admin ui. In the logs on the worker that you have handling your encoding workflows you will see something similar to this in the logs: 2012-06-18 12:20:44 INFO (FFmpegEncoderEngine:174) - [mpeg1video @ 0x18ca7e0] MPEG1/2 does not support 5/1 fps 2012-06-18 12:20:44 INFO (FFmpegEncoderEngine:174) - Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height You can see the whole error in the ticket at: http://opencast.jira.com/browse/MH-8899 The original issue was raised here: http://opencast.jira.com/browse/MH-4897 The fix has been committed to trunk in this file: http://opencast.jira.com/svn/MH/trunk/etc/encoding/matterhorn-movies.properties With the lines changing from: profile.mux-av.work.ffmpeg.command = -strict unofficial -i #{in.video.path} -i #{in.audio.path} -sameq -shortest #{out.dir}/#{out.name}#{out.suffix} to: profile.mux-av.work.ffmpeg.command = -i #{in.audio.path} -i #{in.video.path} -sameq -shortest -strict unofficial #{out.dir}/#{out.name}#{out.suffix} If you need to fix this on your own install you can alter the above first line to look like the second. The fix will be ported to 1.3.x and 1.4.x shortly. Please let me know if you have any questions or concerns.
