This patch lets you pass paths for opus_demo and opus_compare to the run_vectors.sh script. The motivation for this was for my aarch64 patches (forthcoming), which I've been testing under qemu. I want to run an emulated opus_demo, but a native opus_compare, so the script completes in a reasonable amount of time. --- tests/run_vectors.sh | 4 ++-- 1 f...

If opus_compare doesn't exist or isn't executable, tests failed normally which could be misleading.

Dear all, is the program opus_compare capable of comparing each decoder output or is it only capable of comparing the decoded testvectors? Or in other words: Can I use the opus_compare for comparing the decoder output when I have encoded and decoded arbitrary speech files? With best regards, Martin -------------- next part ---------...

...ollowing is applied for a test vector Reference Float Point Encoder --> Reference Float Point Decoder --> Float Point Output Reference Fixed Point Encoder --> Reference Float Point Decoder --> Fixed Point Output And then, if Float Point Output and Fixed Point Output are compared using opus_compare.c tool, the result is 'Test vector FAILS'. Is it as supposed to be ? Or maybe there is some inaccuracy in reference fixed point implementation (libopus 1.0.2) ?

Hi, I am looking at the conformance test using opus_compare and the test vectors and I am a bit confused about FEC. Is there a way to validate that a decoder processes LBRR frames correctly? Thanks, Alexis

...-tools on my Ubuntu system, I have the following problem: When I try to open the test vector 'testvector01.bit', I got the error message 'Decoding complete. This doesn't look like a Opus file'. When I open the 'testvector01.bit.opus' the decoding works fine, but the tool opus_compare mentioned, that the number of samples are not identical in my decoded file and in the reference decoded file, which I assume to belong to testvector01.bit and not to testvector01.bit.opus. How can I decode the official test vector 'testvector01.bit' with 'opusdec'? Or, how can I c...

Hi Drew, Thanks for addressing these issues. A few remaining things: 1) In this line: buf[i] = (opus_int16)demixing_matrix[2*i] + ((opus_int16)demixing_matrix[2*i+1] << 8); you might want to test it with undefined-behaviour sanitizer, but I believe the second term will be undefined for negative values (the value would be positive after the cast and only be negative because of the shift).

Hi, I'm working on porting libopus and I'd like to get information how to test Opus Encoder properly. There is information in RFC6716, that Opus Decoder's test files (http://opus-codec.org/testvectors/opus_testvectors.tar.gz) were created specifically to exercise all aspects of the decoder. Using these files, a custom implementation of libopus can be verified to be sure the Opus

...you'll want something like: > (opus_int16)((unsigned)demixing_matrix[2*i+1] << 8) > (though you might want to check it too) FWIW, we use the construct int s = buf[2*i + 1] << 8 | buf[2*i]; s = ((s & 0xFFFF) ^ 0x8000) - 0x8000; to manually sign-extend the result in opus_compare (and also opus_demo). If you ultimately cast s to (opus_int16), then I'm pretty sure most compilers will turn the second line into a no-op and optimize it away.
