I found this livestream:
I suppose it's one that Michel could use if he wanted to investigate this. It appears to
be a permanent stream. I don't know if there are any country restrictions on it & I
don't know if the URL changes from day to day. If you're searching for it, it's under
the title "partypoker TV LIVE 24/7." I muted the audio & I have to say I wasn't watching
it. I just left it on, running in the background while I did other things.
I took a look at about:memory. I've never looked at that before & it made my eyes spin.
I have no idea how to filter out the noise from the relevant information. Perhaps you
could enlighten me a bit on that score.
I do know how to look at the Windows 7 Resource Monitor. It has a Memory tab. On that,
the memory usage appeared to be quite stable in the 5G-6G range . . . at first. Yes, the
VDH menu got an ever growing proliferation of entries. No, I was not actually using VDH
to download anything. According to the good old Task Manager, my CPU usage was hovering
in the 20%-25% range, enough to keep the fans in my system case blowing at a rate that
was noticeably audible.
I left this running for about 90 minutes or so while I did other things. I was using VLC
to listen to a podcast I had downloaded hours before (not with VDH) & I wasn't even in
front of my computer. Everything seemed to be running fine. But then the podcast
started skipping. Task Manager was showing CPU still in the same 20%-25% range. The
Resource Monitor did seem to indicate memory was being chewed up. I have 8G real RAM &
Resource Monitor was saying most of it was in use. My system became rather sluggish. I
discovered that the live feed had actually stopped, I have no idea when, so I closed it.
I probably should have looked in the VDH menu to see how many variants had accumulated
there but it didn't occur to me until just now. Now that I have thought of it, I find
that the VDH menu won't drop down so I can't look at the orphan count from the YouTube
feed. One side of the menu outline begins to appear but the whole menu does not open &
populate. In fact, Firefox has gone into the "not responding" state. I'm going to have
to kill it from the Task Manager. My entire system is essentially being handcuffed by
this. Oops. No. Firefox did wake up long enough for me to close the last window, which
was a page displaying this discussion thread. It took about a minute but Firefox did
eventually close normally. My CPU usage is back down to negligible. Resource Monitor
shows under 2G in use. The rest of the system has resumed normal responsiveness. I
probably should have checked the Disk tab of Resource Monitor to see whether the system
was thrashing. But things were so unresponsive, I'm not sure it would have responded.
Bottom line: I can confirm there is a problem here. But it seems to be unique to YouTube
because, as I've said, I have streamed operas from XM (will be doing one here in a few
minutes), & the problem does not occur. Mind you, that's audio-only. It is XM
<i>radio</i> after all. Still, it's a livestream & VDH does keep growing its menu on XM.
I have also watched Golf Channel livestreams (definitely video with that audio) while not
recording them in VDH & the problem does not occur. The VDH menu does not continuously
acquire new variants from Golf Channel. So this appears to be a problem just with
YouTube . . . pending other people reporting the same thing on other sites.
