How to set some parameters for opus codec? Is there a demo for it?

I am using opus to compress and decompress audio data, but I don't know how to port it to the SDK. specific process.

Hello,

You can check out the example found in the SDK for the Smart Remote, which is a custom SDK tailored for smart remote applications.If I remember correctly, it is using the opus codec by default. Perhaps you can look into this to see how to port it to the SDK.

hi!

I can now use opus for audio codec, but I found a problem, is its coding efficiency is a bit low, I am a frame data volume for 480 byte of the audio data encoding, I measured it takes 17 ms encoding time, this time is very long, for me when I was a shorter time frame, he completely the coding time can't keep up with the speed of my data.How do I solve it?

Best regards,

That is all we have really. Audio over BLE is not really supported at this point in time. It is currently in the process of happening, but I am not sure of the details, and how this codec is handled. Perhaps you need a more powerful processor. 

In the smart remote SDK this is only used to send voice commands, and not a continuous stream. If that is what you are trying to acheive, I am not sure whether that is possible. Also note that there is currently no way to discard packets in BLE, so if the connection is poor (large distance or a lot of noise), there is no way to discard packets that are not Acked, even though they are getting old.

hi

any update in this

Opus Codec needs to be compiled in Release mode to run properly.
