fix(adaptive-bitrate): correct operator precedence in bitrate calculations

Browse Source 
Fixed NaN errors in FFmpeg bitrate argument generation by ensuring integer
conversion happens before integer division. The double multiplication (1.5, 2.0)
was happening before the ~/ operator, causing NaN values. Now properly converts
to int first, then divides.

- maxRateArg: ((bitrateBps * 1.5).toInt() ~/ 1000)
- bufferSizeArg: ((bitrateBps * 2).toInt() ~/ 1000)

Fixes: Unsupported operation: Result of truncating division is NaN
