Flash with Chromium-based browsers is out of my knowledge, sorry. A quick Google search shows that apparently, at least a few years ago, Chromium/Chrome used to disable hardware acceleration for certain graphic cards. Knowing the limited capabilities of the AMD/ATI Radeon HD 6310 (an APU-integrated graphic card that equipped my dad's early 2010s mini-desktop computer), perhaps hardware acceleration is indeed disabled for this card. In which case, it might be forced, and perhaps the following (dated) links can still help:
http://askubuntu.com/questions/325431/hardware-acceleration-of-chromes-flash-plugin http://www.webupd8.org/2014/01/enable-hardware-acceleration-in-chrome.html You should also install a Mozilla-based browser (and the PPAPI/NPAPI wrapper browser-plugin-freshplayer-pepperflash), enable hardware accelerated decoding (see comment 1), and see if you can reproduce this issue (no hardware accelerated H.264 in Flash videos). This would help find out whether it's the browser's fault or the plugin's fault (cause I'm not sure this bug should be filed against the plugin). ** Changed in: adobe-flashplugin (Ubuntu) Status: Expired => Incomplete ** Summary changed: - No hardware acceleration for H264 Decoding in Pepper Flash Plugin + No hardware acceleration for H264 decoding of Flash videos on Chromium with Pepper Flash plugin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1596027 Title: No hardware acceleration for H264 decoding of Flash videos on Chromium with Pepper Flash plugin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/adobe-flashplugin/+bug/1596027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
