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.

Description of problem:
When I go to vimeo site with the RHEL Firefox (e.g., http://vimeo.com/40168555) I get just an error message "This video can't be played with your current setup". Which is strange, because I know that the upstream Firefox (e.g., the one from http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/31.0esr/linux-x86_64/en-US/firefox-31.0esr.tar.bz2) uses the Cisco H264 codec and vimeo works.

Version-Release number of selected component (if applicable):
firefox-31.2.0-3.el7_0.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Go to any vimeo webpage (or any page with HTML5 <video> element with H264 video)
2.
3.

Actual results:
error message

Expected results:
Firefox should download a binary Cisco codec (https://blog.mozilla.org/blog/2013/10/30/video-interoperability-on-the-web-gets-a-boost-from-ciscos-h-264-codec/) and use it, so that user doesn't notice anything.

Additional info:

See https://www.mozilla.org/en-US/firefox/33.0.2/releasenotes/ the OpenH264 support was shipped in Firefox 33.

OK, so apparently that upstream Firefox doesn't play it via Open264 codec but in some different way (GStreamer? bug 843583 ?) but I still hold that the upstream binary 31ESR does play the video which our RHEL-7 Firefox doesn't.

For the video issue please check Bug 1161077. As for H264 it's not supported so closing as WONTFIX.
