[Desktop-packages] [Bug 1323822] Re: Firefox can not play some WebM videos generated by avconv on Trusty
I did not find any libav 9.14 package for Ubuntu (any version), so I finally compiled it myself on Trusty, from mainstream source. After converting the source video with the same command-line, it outputs the attached webm file, which works correctly in Firefox. In order to check that the issue did not come from the patches of Ubuntu (or the compilation options I used), I also compiled version 9.13 from source, and reproduced the issue in Firefox. So version 9.14 of libav solves the issue. It's certainly the same issue as in the libav bugtracker mentioned above : a bug in libav that makes it generate corrupt webm files. Would it be possible to upgrade libav to 9.14 in Trusty? ** Attachment added: "WebM file generated on Trusty with libav 9.14" https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1323822/+attachment/4149877/+files/P5270914-trusty-avconv-9.14.webm -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1323822 Title: Firefox can not play some WebM videos generated by avconv on Trusty Status in The Mozilla Firefox Browser: Confirmed Status in “firefox” package in Ubuntu: Confirmed Status in “libav” package in Ubuntu: Confirmed Bug description: Steps to reproduce : - Download the source H.264 video attached to this bug - On a Trusty machine, convert this video to WebM with "avconv -i P5270914.MOV P5270914-trusty.webm".

[Desktop-packages] [Bug 1323822] Re: Firefox can not play some WebM videos generated by avconv on Trusty
For what it's worth, if it might help somebody : As a temporary workaround before this issue is fixed, I succesfully use Docker (http://packages.ubuntu.com/trusty/docker.io) to convert my videos in an isolated environment. I prefer not to install ffmpeg or upgrade libav through PPAs on my main system (Some other applications depend on libav and I don't want to break them), and it's a very lightweight solution compared to starting a complete virtual machine. I used a Trusty image provided by the official repo of Docker (https://index.docker.io/_/ubuntu/) and configured the ffmpeg PPA in it. After commiting my modified image (called trusty-ffmpeg below), I can run the conversion with a command-line like : sudo docker run -i -t -v /home/mossroy/Videos:/host trusty-ffmpeg ffmpeg -i /host/P5270914.MOV /host/P5270914-trusty-docker.webm (note that I use the -v option to map the path of my video to a /host directory inside the docker container) It gives the same result as https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1323822/+attachment/4121477/+files/P5270914-trusty-ffmpeg.webm , which works properly in Firefox.
