Bug Description
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.

Thanks for the bug report. Can you please also attach the following information?...
1. Text output from 'lspci -k'
2. Text output from 'mpv bbb_sunflower_ 1080p_60fps_ normal. mp4'
3. Text output from running 'dmesg' after the lag problem has just happened.
4. Please clarify what you mean by "lag". Do you mean the audio is playing back earlier than the video? Or do you mean the frame rate is low?
5. While the "lag" problem is occurring, please also run 'top' in a terminal window and tell us if any process is using high CPU.
