[Lubuntu-qa] Video Problems - Saucy

[Phill Whiteside]

Hi,

I have one of these... http://phillw.net/hardware/aDU4RVzY A Win7 machine
with a decent graphic card and 4 GB of RAM. When ever I play flash movies
in a browser, the CPU usage goes from a quiet

Tasks: 176 total,   1 running, 174 sleeping,   0 stopped,   1 zombie
%Cpu(s):  9.5 us,  4.2 sy,  0.0 ni, 83.8 id,  2.5 wa,  0.0 hi,  0.0 si,

To...:

Playing Video via a browser is 'expensive'... now let me try it with the
downloaded version of same video.. :

Tasks: 181 total,   1 running, 179 sleeping,   0 stopped,   1 zombie
%Cpu(s): 16.9 us,  3.7 sy,  0.0 ni, 76.1 id,  3.2 wa,  0.2 hi,  0.0 si,
 0.0 st
KiB Mem:   3787680 total,  3340228 used,   447452 free,   175168 buffers
KiB Swap: 10166660 total,    30136 used, 10136524 free,   986256 cached

Now, this time the machine is playing the flash video in VLC (That is a new
programme started). So, browsers do not like playing flash movies.... which
oddly enough is not that suprising as they are browsers and not media
players like VLC is). The sooner we are rid of flash, the better.

Ali, if you want, I'll do a compare of html5 vs flash on you-tube to also
show you the difference in CPU time.

Regards,

Phill.
