Support JPEG format

[FreddyFunk]

Format Details

• Type: Compressed
• Description: Hardware-compressed JPEG from ISP (Image Signal Processor)
• Characteristics: Lossy compression, widely supported

Implementation Requirements

• Parse hardware JPEG data from camera stream
• Decode JPEG data efficiently
• Handle various JPEG quality levels

Notes

Some cameras provide hardware-compressed JPEG output directly from the ISP, which can be more efficient than compressing in software.

This format is now implemented. JPEG is supported both as MJPEG input codec for camera capture and as JPEG photo output format with configurable quality levels (Low/Medium/High/Maximum).
