Comprehensive camera validation using GStreamer with qtiqmmfsrc or libcamerasrc.
Auto-detects available plugin (qtiqmmfsrc: 10 tests, libcamerasrc: 7 tests).
Tests run in sequence: Fakesink -> Preview -> Encode.
qtiqmmfsrc supports NV12 (linear) and UBWC (Qualcomm compressed) formats.
libcamerasrc supports NV12 only.
Auto-detects available plugin (qtiqmmfsrc: 12 tests, libcamerasrc: 9 tests).
Tests run in sequence: Fakesink -> Preview -> Encode -> Snapshot.
qtiqmmfsrc supports NV12 (linear) and UBWC (Qualcomm compressed) formats, plus snapshot tests (1080p, 4K).
libcamerasrc supports NV12 only and includes snapshot tests (1080p, 4K).

### qtiqmmfsrc Tests (10 Total)
### qtiqmmfsrc Tests (12 Total)

| Category | Tests | Formats | Resolutions | Description |
|----------|-------|---------|-------------|-------------|
| Fakesink | 2 | NV12, UBWC | 720p | Basic capture validation |
| Preview | 2 | NV12, UBWC | 4K | Display on Weston |
| Encode | 6 | NV12, UBWC | 720p, 1080p, 4K | H.264 encoding to MP4 |
| Snapshot | 2 | NV12 | 1080p, 4K | JPEG still image capture |

**Format Notes:**
- **NV12**: Standard linear format (universal support)
- **UBWC**: Qualcomm compressed format (Qualcomm optimized)
- **Snapshot**: Uses NV12 format only
