And if I remove the video instead of the audio (-vn option instead of -an), it does not play either and "jumps" to the end of the stram. I tried to tweak the libvorbis options on bitrate and quality values, but it does not seem to make any difference.
I also tried to manually modify the header properties with mkvpropedit, but it always seems to delete both audio and video tracks in the header, giving a file considered corrupted by Firefox (but still playable on Totem, VLC and Chromium... It looks like these players are less dependent on the mkv header) -- 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: New 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". It should give the same result as attached - Open this webm file in Totem or in VLC : it plays correctly - Open this webm file in Firefox 29. When you click on play, it goes directly to the end and does not show anything - Open this same webm file in Chromium (tested with version 34) : it plays correctly If you generate the WebM file on Precise, with the same command-line, it plays correctly in Firefox (see attached P5270914-precise.webm). So I suppose it comes from a difference in the way avconv does the conversion, that is not correctly supported by Firefox All tests are made with Precise and Trusty amd64, with all current updates. Firefox version 29.0 on both avconv 9.13-0ubuntu0.14.04.1 on Trusty, and 0.8.10-0ubuntu0.12.04.1 on Precise To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1323822/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
