hang after first stage in multiStage for android

[jniemann66]

I have replicated this when SIMD vector FIR filter is deactivated in favor of the scalar FIR filter (which is currently the case for Android), It occurs when adding a new converter stage to the vector of converters using emplace_back. Not sure why just yet.

Ok problem was to do with allocating / deallocating kernel phases in the polyphase FIR filter. With SSE2, there are 4 kernel phases With AVX, there are 8 kernel phases but with no SSE2/AVX vectorization (ie scalar calculations) , there should only be one kernel phase. to cut a long story short - needed to set numVecElements to 1 when in scalar mode. Just tidying up - should have a commit soon. Sorry about that - it also explains a long-standing bug I have had with the 32-bit / no-SSE version. duh !

ok, just fixed up my repo and synced with yours (was a bit difficult to figure out how to do correctly as I was missing the latest commit from your repo even though I pulled from upstream), i may need to revert and repull to get squash the 3 "merge with master and fix empty cout value with no message" commits into a single commit however i am not comfortable with doing that as i dont want to accidentally mess up my repo's commit history

(literally just replace https://github.com/jniemann66/ReSampler/blob/master/ReSampler.cpp#L180

            if (ci.outputFormat) {
#ifdef COMPILING_ON_ANDROID
                ANDROID_OUT("Changing output bit format to %s", ANDROID_STDTOC(ci.outBitFormat));
#else
                std::cout << ci.outBitFormat << std::endl;
#endif
            }
            else { // user-supplied bit format not valid; try choosing appropriate format
                determineBestBitFormat(ci.outBitFormat, ci.inputFilename, ci.outputFilename);
                ci.outputFormat = determineOutputFormat(outFileExt, ci.outBitFormat);
                if (ci.outputFormat) {
#ifdef COMPILING_ON_ANDROID
                    ANDROID_OUT("Changing output bit format to %s", ANDROID_STDTOC(ci.outBitFormat));
#else
                    std::cout << "Changing output bit format to " << ci.outBitFormat << std::endl;
#endif         
                }

with

            if (ci.outputFormat) {
                std::cout << "Changing output bit format to " << ci.outBitFormat << std::endl;
            }
            else { // user-supplied bit format not valid; try choosing appropriate format
                determineBestBitFormat(ci.outBitFormat, ci.inputFilename, ci.outputFilename);
                ci.outputFormat = determineOutputFormat(outFileExt, ci.outBitFormat);
                if (ci.outputFormat) {
                    std::cout << "Changing output bit format to " << ci.outBitFormat << std::endl;
                }

I just updated master - should be good now :-)

[mgood7123]

ok, so it is ready to test? or do you still have more work to do before i can pull and test?

[jniemann66]

Yes - you should be able to test it now. (I still need to do the raw file input stuff, though ... )

[mgood7123]

imma just refork this repo lol

[jniemann66]

Sorry about the refork

[mgood7123]

its ok, needed to clean up my commits anyway lol

[mgood7123]

and im building now

[mgood7123]

and it sucesfully builds (with 3 warnings)
