The C3V platform comes with hardware video codecs and supports V4L2 and OpenMAX interface calls. Here is the comparison of the performance of the different interfaces:
Encode Support | Maximum WxH@FPS | Multi-Encode | Decode Support | Maximum WxH@FPS | Multi-Decode | Framework Support | |
|---|---|---|---|---|---|---|---|
V4L2 | H.264 | FHD@60 | support | H.264 | FHD@90 | support | GStreamer FFmpeg |
JPEG | 4K@12 | support | JPEG | 4K@20 | support | ||
VP8 | FHD@60 | support | \ | \ | \ | ||
OpenMAX | H.264 | FHD@60 | unsupportNA | H.264 | FHD@90 | support | GStreamer |
