Isadora movie player performances with respect to VLC

[ikse]

Dear Mark,

I should be able to give it a try later today and come back to you with some outcomes on triple-buffering. The post seemed rather optimistic.

Best regards from sleeping Paris,

Dear Mark,

My settings on Quartz Debug : enable “Force Quartz GL” and set Beam Sync to “Disable”.
I read it from here : http://www.chromescreen.com/speed-up-mountain-lion/ . (Note that I am under OSX 10.)

Hope it helps.

Best

Dear Mark,

Please find attached the outcomes of the quick tests I made with two 2K movies onto two 2K monitors. I am sorry to say that I did not see any change while playing with the triple buffering, the number of pre-rendered frames, or the vertical synchronization as the Quadro 4000 allows. I should say that, back to the initial comparisons with VLC or MPC, it is not surprising as none of the three softwares seem to overwrite the driver's configuration - even though one can specifically do so. Hence, no improvement might have been retrospectively expected.
I hope it will help tracking it down.

Best regards,

Ikse

P.S.: Hopefully the file names are explicit. The framerate is in any case stuck to 10 fps.

When you say 2K movies, do you mean 1920 x 1080? Just want to be sure what we're talking about.

Best Wishes,

Mark,

Just coming from a very interesting theater series (7 and 8th episodes of Une Faille) where Isadora was finely used for entangled videos on stage. A beautiful video (and theater) work to be seen in Montreuil until the end of the week www.nouveau-theatre-montreuil.com
I meant 2048x1556 as I did in the former test with the vblank removal on May 15th. The higher the resolution is the easier it is to reveal the frame dropping. At standard resolution, it is barely noticeable. At high resolution (1920x1080), it starts impeding the overall patch performances while saturating on core cpu. The two stages were of the same size 2048x1556. The same patch worked fairly well when, following the trick, the vblank was disabled (25 fps with some slack on the cpu).

Dear Mark,

I am facing stability issues with the adapted-vblank-disable version f02 - the video works fine but the patch keeps on crashing while listening to a set of osc inputs. Would you have any update on late developments for a new version?
Thanks a lot.

For those who pass by Paris, Dynamo at the Grand Palais is an exhibition to see. www.grandpalais.fr/fr/evenement/dynamo

As always, if you're on Mac OS use the applet and send me the crash reports so I can analyze. For Windows users of the pre-release version, the crash reports are transmitted to me automatically. Make sure to include your email address an a description of the problem when sending on Windows.

The OSC crashing issue likely has nothing to do with the vblank-disable thing. They are really not related.

Due to Troika Ranch's recent gig in Moscow and the even more recent Berlin workshop, I haven't been examining these crash reports. But will start looking them over them this week and get back to you as soon as I can.

Best Wishes,

Mark
