Hi,I'm trying to generate Performance Advisor(html) with Unity debuggable sample application, but facing "Cannot find any frames" error.

Please help to share solution
Hi Hiroki, my name is Connor, I work at Arm as an engineer on the Streamline tool. A few things I'd like to check: 1) You are running streamline_me.py with the OpenGL ES debug layer, is your application you want to profile using the GLES API? Could it be that you should be using the Vulkan Debug Layer? 2) If the app is using GLES, can you please open the capture in Streamline GUI, do you see any charts for Frame Rate, Draw Calls per Frame etc.? 3) On the timeline tab in the Streamline GUI, if you click at the bottom where there is a drop down list (usually set to "Heat Map" by default), can you see if the "Performance Advisor" option is available in that list? If you cannot see a frame rate graph or the performance advisor view in that list, that would explain why PA could not generate a report. The streamline_me.py script has not been able to successfully get frame data. Please let me know about these things. Can I also suggest that you update to the latest version of Streamline (v9.3.1, in Arm Performance Studio 2024.5) just to ensure the tool is the most up to date it can be.Thanks, Connor
Hi Connor,Thanks so much for prompt reply !!
1)Sorry, I may not understand, you mean Streamline & Performance Advisor supports either GLES or Vulkan API ?learn.unity.com/.../2d-platformer-templateI'm using Unity sample application(2d-platformer) in order to know how Performance Advisor works.I don't modify any code of it, just utilize this sample app with debuggable build.Not sure detail which API this application is using.Do I need to indicate GLES or Vulkan by streamline_me.py script options ?2)I cannot find Frame Rate and Draw Calls per Frame...May I know how to enable it ?3)I only can see "Heatmap", "Core map", "Sample", "Process", "Mali Timeline" in drop down list on Streamline GUI.
Noted, I'll try again on latest version.
Thanks Hiroki, yes so we support both Vulkan and GLES API. In streamline_me.py you can specify which API you would like to enable the debug layers for, in the output you sent, you can see GLES is being used as it says: "Installing OpenGL ES debug layer". To specify a specific layer you can use: --lwi-api. Try this with both --lwi-api "gles" and --lwi-api "vulkan" and see if you can get frame data. It is worth pointing out that in the newer version of Performance Studio, streamline_me.py automatically gets data for both GLES and Vulkan, and therefore specifying --lwi-api is not required. Let me know how this goes! Connor
Hi Connor,Thanks for your explanation.
Arm Performance Studio : 2024.1I can see framerate related data("Frame Rate", "Workloads / Frame", "Draw Calls / Frame") on Streamline GUI by applying "--lwi-api vulkan" option, and generate Performance Advisor successfully ! It means I guess my Unity sample app is using Vulkan not GLES API.Arm Performance Studio : 2024.5I also can get framerate related data without "--lwi-api" option.
I understand that I used old version Streamline and I referred latest version Streamline documentation, that's why I faced this issue.Thanks so much for updating to useful tools.
BTW, in case of System profiling, framerate related data couldn't be got in my understanding.It will be supported in the future for System profiling ?
Best Regards
