Decode very slow on Raspberry Pi Zero #7

I compiled from source using the WITH_FFMPEG backend. Playback is not possible, decode speed is lower than realtime. Using AAC I get 13% CPU usage.

Is this a problem in ffmpeg? Not sure where to raise this issue.

I assume that you are using openaptx with bluez-alsa. If that's true, please switch to libopenaptx (unless you are using proprietary Qualcomm libraries), that should give you better overall performance.

That fixed it, thanks. Maybe the readme could be updated to recommend libopenaptx?

Yes, you are right. I'll do that :)
