RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Prior to this update, the unicap utility did not check for a return value of the Theora encoder initialization. As a result, unicap terminated unexpectedly if the initialization of the Theora encoder failed. With this update, the bug has been fixed by adding the missing check for a return value in order to handle failure of the Theora encoder initialization gracefully.

This is a repeat of bug 587800 but as I am now running Fedora 13 (old bug on 12) I thought it 
better to register a 'new' bug.

How to reproduce
-----
1. select Celestron NexImage camera
2. start recording.
3.

This issue was proposed for RHEL 6.1 FasTrack but did not get resolved in time.
It has been moved to RHEL 6.2 FasTrack.
