Chrome trace cc::DisplayItemList - SkPicture rasterization problem

[sarath.s...@gmail.com]

Hi,

I am trying to see the frames content from the chrome trace taken from Android chrome.

I enabled “cc::DisplayItemList” and got the frame dots in the trace, But chrome "Cannot rasterize..", I tired with "--enable-skia-benchmarking" flag also.

I can save the picture as .skp file, but I do not have SkPicture viewer or debugger tool.

Is there any way to see the content form the trace?

Thank You,

Sarath

I'm not sure why --enable-skia-benchmarking doesn't work, but failing that the Skia Debugger is a handy way to view skp files:

• Can you share a trace?
• What version of chrome are you using?
• Which OS?

I compiled a debug build, ran with --enable-skia-benchmarking, recorded a trace using the Frame Viewer preset (blink,cc,gpu,renderer.scheduler,v8,toplevel,disabled-by-default-cc.debug,disabled-by-default-cc.debug.picture,disabled-by-default-cc.debug.display_items), and found the skps worked, with some errors in the dev console that I'll file a bug about.

Hi,

I have built the same chrome linux version and SKP rendering worked with --enable-skia-benchmarking option.

Thank you.
