Flash Full Screen SLOW

[deedod]

I've got a custom FLV video player that I've
setup with a true full screen popup similar to
that of YouTube's.

When the video is in the normal browser mode
the CPU load runs up to like 1 - 2% max. However,
when I make the video jump to full screen mode
the CPU load skyrockets up to 15 - 20% and just
sits there for the entire video.

I didn't add any extra functionality for when the
video is in full screen mode so I'm baffled as to
why the huge jump in CPU load occurs. Also,
the memory rate stays virtually the same in normal
and full screen mode.

Any ideas?

What is it that you find so strange about this? When you show your video in browser mode there are probably a lot lets pixels for the CPU to render. However, when you go to fullscreen mode suddenly the video image needs to be scaled up and any more pixels need to be rendered.

Imagine you had to carry a 100 buckets to the sea in 1 hour which would we quite easy. Suddenly they changed your task that you now have to do a 1000 buckets in an hour (in other words, the resolution has changed). That would probably require a lot more effort, don't you think?

You mean 100 x 100 = 10000 buckets...

I understand the concept that it takes more
CPU to render the screen. It's just to me
20% seems like quite a bit.

When I watch a full screen video with another
media player like media player classic I only see
the CPU go to about 10%.

Just seems like Flash is inneficient and needs
a few improvements in the full screen department.

Just my thoughts. Thanks for your input.

Make sure you don't have anything with filters (like GlowFilter) rendering on top of the video. I did this and noticed that for fullscreen there was quite a penalty hit there. But even without the filters, it's not so surprising, as pan69 said. Even so, I think you are right that FP could use some improvements in the fullscreen rendering department. Perhaps some improvements are coming with the next update

Why do you always get what you ask for???

Truth is, I've already seen that when I made the comment above.
The H.264 support is especially astounding. (And with Silverlight supporting VC-1 ( http://weblogs.asp.net/scottgu/archi...announced.aspx ), there is the high-quality video split in the industry.

The new video codec is nice and since On2 have been so possessive of their codec (lack of Flash 8 video for ffmpeg e.g.), it was just a matter of time. People just don't want to shell out big buck these days for video encoding.

I was personally more excited about the mutilcore support.
