The C3V platform comes with features a hardware video codecs and supports codec, supporting V4L2 and OpenMAX interface calls. Different interfaces differ in their functional support:interfaces. Below are the support and performance details:
Interface and Codec Support

OpenMAX | H.264 | FHD@60 | NNot supported | H.264 | FHD@90 | Y |
OpenMAX only supports H.264, but V4L2 also supports JPEG and VP8.
OpenMAX only supports GStreamer calls, but V4L2 also supports FFmpeg.
V4L2 does not support VP8 decoding.
