Questions Regarding Opus Test Vectors
I downloaded test vectors from opus-codec.org site. The site indicated that the test files are intended for verifying that the Opus decoders are operating properly. I assume I could also use them to verify my encoder implementation, right? For example, use testvector01.dec as input to my encoder and compare its output bitstream with the corresponding testvector01.bit bitstream file. Any idea

DTX Seems to be Wrong for 10ms Frame Size
Tested DTX feature in Opus 1.0.2 and 1.1 for 20, 40, and 60ms frame size. They all generated only one encoded frame every 400ms during silence period as expected. However, for 10 ms frame size, the DTX period was 200ms instead. Has anyone else experienced the same? Thanks, Chris Wang -------------- next part -------------- An HTML attachment was scrubbed...

libopus API question - 120ms encoding
Thanks Jean-Marc and Benjamin for the answers. One follow-up question. If I use a repacketizer as Jean-Marc suggested by combining two 60ms frames to form a 120ms frame, without extracting individual frames and using a new TOC, I would need to have a "de-packetizer" that does the exact opposite of repacketizer. De-packetizer would need to separate this 120ms frame into two 60ms frames

libopus API question - 120ms encoding
Hi Jean-Marc, A simpler question. How does opus_encode() generate packets of 20ms (SILK-only or Hybrid)? Concatenating two 10ms frames or doing it straight with just one 20ms frame?
