i downloaded Linux version of aomanalyzer and failed to open - "First argument must be a decoder"

[slavah264]

i downloaded aomanalyzer package (version 1.0.0).
When i apply ./AOMAnalyzer i receive the error "First argument must be a decoder.":

./AOMAnalyzer ./aomdec ../av1/test2.ivf
First argument must be a decoder.

i tried without mentioning 'aomdec' - the same error is issued.

How to run AOMAnalyzer on a specified ivf-file (av1 content)?

The first argument should be a JS compiled decoder. You'll need to use Emscripten to compile the decoder to JavaScript. The details are described here

Thanks for prompt replay.
i installed emsdk. However, within the directory 'tools' of AOMCodec when i run 'build_inspector.sh' the following error is issued:

tools$ ./build_inspector.sh --disable-multithread --disable-runtime-cpu-detect --target=generic-gnu
Building JS Inspector
make: *** No targets specified and no makefile found. Stop.
cp: cannot stat 'examples/inspect': No such file or directory
ERROR:root:inspect.bc: No such file or directory ("inspect.bc" was expected to be an input file, based on the commandline arguments provided)
cp: cannot stat 'inspect.js': No such file or directory

Indeed, the file "inspect.bc" is not exist in ".inspect" folder as well as at any other place. How to generate "inspect.bc"?

Can you just run ./build_inspector.sh, you don't need the extra arguments. The shell script bakes in those options.

[slavah264]

the script invokes emcc
emcc -O3 inspect.bc -o inspect.js -s TOTAL_MEMORY=134217728 -s MODULARIZE=1 -s EXPORT_NAME="'DecoderModule'" --post-js "../inspect-post.js" --memory-init-file 0

where is build_inspector.sh, seems there is no such in latest aom repos.

I fixed the docs, AOM repo now does this using CMake - see 7e3eca9 and https://aomedia.googlesource.com/aom/#emscripten-builds

@slavah264 can you follow the directions in the AOM repo and see if you're able to run the analyzer that way?
