Failed to load java script decoder from AOM analyzer

[shihuade]

following the build instruction from build step in step 4, AOM analyzer failed to load the javascript decoder inspect.js.

AOM decoder commit ID(master branch): a07a3b2854e7b743adba13bca8adc9a993403075 Analyzer download from Mac 1.1

Does the problem persist if you use this decoder an this video file.

Were you able to compile the inspect.js successfully? Can you paste your console output?

1. I install the emsdk from offical website emsdk for Mac and update/install/activate/setup env path info based on [instruction]()

2. and building aomdec with emsdk followed build step

the comand I build with cmake is

cmake .. -DENABLE_CCACHE=1 \ -DAOM_TARGET_CPU=generic \ -DENABLE_DOCS=0 \ -DCONFIG_ACCOUNTING=1 \ -DCONFIG_INSPECTION=1 \ -DCONFIG_MULTITHREAD=0 \ -DCONFIG_RUNTIME_CPU_DETECT=0 \ -DCONFIG_UNIT_TESTS=0 \ -DCONFIG_WEBM_IO=0 \ -DCMAKE_TOOLCHAIN_FILE=../../EmSDK/emsdk-portable-latest/emscripten/1.37.33/cmake/Modules/Platform/Emscripten.cmake

3. and the output is

4. and then make inspect to generate example/inspect.js

[shihuade]

1. when calling AOM analyzer with below command: /Applications/AOMAnalyzer.app/Contents/MacOS/AOMAnalyzer --frames 1 --dev examples/inspect.js examples/Test.ivf

the output looks like

2018-02-11 14:08:09.087 AOMAnalyzer[36627:860846] IMKInputSession [0x7ffc1c6c9240 presentFunctionRowItemTextInputViewWithEndpoint:completionHandler:] : [self textInputContext]=0x0 NO NSRemoteViewController to client, NSError=Error Domain=NSCocoaErrorDomain Code=4097 "connection from pid 0" UserInfo={NSDebugDescription=connection from pid 0}, com.apple.inputmethod.EmojiFunctionRowItem

[shihuade]

[shihuade]

the file path looks like: file:/// wiht 3 "/", is it correct?

[mbebenita]

How about the errors in the browser console? With the --dev flag, you should be able to see the Chrome DevTools and see what the console errors are.

Can you upload the inspect.js and .ivf files somewhere so I can take a look?

[rogerzhou-github]

Hi mbebenita, got same error as shihuade. Built the inspect.js successfully, but the analyzer cannot load. The analyzer works fine on the decoder and input file provided by you. Uploaded the inspect.js and input file. test.zip

[mbebenita]

Thanks @rogerzhou-github, it looks like for some reason your inspect.js file doesn't export the UTF8ToString function that the analyzer expects. How did you build the inspect.js file? Using the directions in the AV1 code base?

[mbebenita]

@rogerzhou-github what version of Emscripten do you have? According to the docs, the function is exported by Emscripten. Also, how did you install Emscripten?

[mbebenita]

@rogerzhou-github looks like Emscripten has changed the list of exported functions, I'll have to add UTF8ToString to EXTRA_EXPORTED_RUNTIME_METHODS in the AOM repo.

[rogerzhou-github]

@mbebenita I am using 1.37.34. Which emscripten version are you using? An older version of emsdk may work. BTW, please let me know after you add the support in the AOM repo. Thanks!

[rogerzhou-github]

@mbebenita, I went back to 1.36.14, and it works.

[alibertb]

Hi, also got an issue in loading decoder. The analyzer still loading decoders. I tried both emscripten 1.38.6 and 1.36.14. I tried the decoder and the input file provided by you and got a black screen on analyzer.
