Hi,

Since the resolution limit on the new open-sourced VP8 codec (WebM) is ~16K x 16K, will VLC be able to playback this type of resolution when sitting on top of the SAGE environment from UIC?

Also, does H.264 have a resolution limit of ~4k x 2K (Level 5.1) or can you go higher? If so, what is the highest possible with the VLC Player?

Thanks for your help!

I doubt VLC can go up to 16K x 16K in one window.

To my knowledge VLC can go at least to 32kx32k pixels on X11. But I don't know any hardware that would practically allow this.

thx for the info, but my concern was more wrt to swscale.
Of course, with xv, you shouldn't need swscale...

I don't know any GPU that can scale 16kix16ki.
My xvinfo reports: And IIRC, my Intel adapter only scales from up to HD resolution (1920x1080). So XVideo does not work at very high resolutions, and software scaling needs to be used.

But sure - swscale is going to be gigantically slow at such high resolution, if it works at all. So will decoding be.
