fix: Address PR review comments
- Update debug test to use BGRA format instead of MJPEG
- Rename test suite to better reflect its purpose
- Update example scripts to demonstrate BGRA as the working format
- Add clear warnings about H264/MJPEG format limitations
- Show real-time FFmpeg conversion examples for BGRA format
- All tests passing successfully
