The C3V platform comes with hardware video codecs codec and supports V4L2 and OpenMAX interface callsinterfaces. Here is the comparison of the performance of the different interfaces:are the support and performance tables:
Interface | 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 |
MJPEG | 4K@12 | Support | MJPEG | 4K@20 | Support | ||
VP8 | FHD@60 | Support | Not supported | Not supported | Not supported | ||
OpenMAX | H.264 | FHD@60 | Not supported | H.264 | FHD@90 | Support | GStreamer |
