Fix AirPlay functionality

Current Behavior

• User films video in portrait orientation

• User attempts to AirPlay video to television

• App rotates the video content but keeps portrait mode dimensions

• Result: Stretched, sideways video with poor visual quality

Expected Behavior

• Portrait videos should properly adapt to landscape television display

• Video should maintain correct aspect ratio without stretching

• Content should be properly oriented and scaled for optimal TV viewing experience

Proposed Solution

Implement proper aspect ratio handling for AirPlay functionality that:

1. Detects when portrait videos are being AirPlayed to landscape displays

2. Automatically adjusts video orientation and scaling appropriately

3. Maintains video quality and proper proportions on the target display

4. Provides seamless transition between device and AirPlay viewing
