2496 capability

[omnipop]

Hi there,

I am new to this site, but wanted to thank you for developing this software. It works well.

I have the Chromecast audio, which can stream at 24 bit 96K resolution. The app goes up to 48 K and does not indicate the bit rate in flac or wav. If the app needs improvement , it is that.

Thank you again

@omnipop thanks for your message. It turns out that ffmpeg does not have any option to change the bitrate for the wav code, AFAICR. If I understand correctly, in ffmpeg the bitrate for wav is 1411 kb/s, while flac is ~900 kb/s. And the '-acodec', 'pcm_s24le' option assures the 24bits. You can verify that when launching mkchromecast with the --debug flag.

As for the 96kHz, I will modify the code so that it accepts it. However, note that if your audio source is "low", let's suppose 44.1kHz, re-sampling it to 48kHz or 96kHz is not recommended.

I think it is done. Commit ec10bfb introduces your request. Casting with wav + 96kHz or flac + 96kHz should reach the 24bits/96kHz google cast audio capability.
