Public bug reported:
Advised to file a bug report after posting on "Call for testing: Video
playback in 18.04".
Running 18.04 LTS as fresh install (not upgraded from previous version -
older version still installed in separate partition). Xorg session.
System: HP Pavillion DV7 (lm726av) - Intel Core i7 2630 processor,
integrated Intel video
Playing any local video file (regardless of video format - flv, mp4,
avi), the video will randomly lag in playback. Audio is not affected, it
plays back correctly. Very occasional lags in browsers (Firefox and
Chrome) on pages with a lot of active graphics (flash or HTML5). Browser
lags significantly improved after installing synaptic driver for
touchpad operation (I have no idea why this would affect video playback
- I simply note that it happened).
I can pick a random video on YouTube and watch it in Firefox or Chrome
without lag (even full-screen). However, if I grab a local copy of the
video (using, for instance, Clipgrab) and play it using Totem, I get
lag.
I was also advised to try using mpv - I still get lag in mpv, although
not as pronounced.
