Detecting Black Gaps in Video Sent to Playback
 
A user might unintentionally include gaps in the video track that result in black gaps in the video output. This could cause a problem when the sequence is sent to playback. MediaCentral UX v2.1.2 and later includes an option to check a sequence for black gaps in the video. If the system detects black gaps, one of the following occurs, depending on how this option is configured:
NONE: No message is displayed and the sequence is sent to the playback device.
WARNING: A warning message is displayed and the user can either continue the operation or cancel it.
ERROR: An error message is displayed and the process is canceled.
After viewing the warning or error, the user can edit the sequence to remove the black gaps and retry the STP operation.
*This feature applies only to advanced sequences.
An administrator needs to edit the Application Properties file to configure this option. If SSL certificates are being used, the Application Properties file will already exist. Otherwise, create the file using vi and add the line indicated in the following procedure.
*You can examine the contents of the default file in the following directory: /opt/avid/avid-interplay-central/config. However, do not make your changes in that file, since it will be overwritten any time you upgrade MCS. Make your changes in the file you locate or create in /opt/avid/etc/avid/avid-interplay-central/config, as indicated in this procedure.
If you use the default file as a model, the file you create should contain only the values you want to override.
To enable a warning message:
1. Log in to the MCS master node as root.
2. Create or open the Application Properties (application.properties) file for editing:
vi /opt/avid/etc/avid/avid-interplay-central/config/application.properties
3. Add the following line to the file:
system.client.stp.video-gap-warning=WARNING
Substitute ERROR for WARNING if you want an error message that cancels the operation. Substitute NONE if you do not want any message.
4. Close and save the application.properties file.
5. If you are configuring a cluster, securely copy the Application Properties file from the master to the slave node using the Linux scp command:
scp root@<destination_hostname>:/opt/avid/etc/avid/avid-interplay-central/
config/application.properties ./
6. On the master node, restart the AvidIPC resource (that controls the avid-interplay-central service) so MediaCentral picks up the new settings:
crm resource restart AvidIPC
In a single node deployment restart the service directly instead:
service avid-interplay-central restart
7. Users who are signed in to the MCS server will be automatically signed out from MediaCentral UX and will need to sign in again to use this feature.
