[PATCH] chromecast: transcode audio to MP3 320 kbps instead of 96 kbps

[ValdikSS]

Chromecast transcoding code uses either Vorbis or MP3 for audio.
For Vorbis, quality=4 is used, but for MP3 no bitrate or quality
setting is set, which leads to default 96 kbps poor quality audio.

This patch explicitly sets 320 kbps bitrate for MP3, for much
better audio quality.

Tested on Chromecast 3.
