About V550

The model requires an external OpenMAX (OMX) IL implementation for codec functionality. By default, V550 looks for ffomaxil.dll on Windows or libffomaxil.so on Linux in the model binary's directory or in the Fast Models installation. The default library path can be overridden using the parameter omx-library-path.

FFomaxIL is an OMX IL implementation provided by Arm in the Third-Party IP (TPIP) package for convenience. Refer to the TPIP package for more details on FFomaxIL.

When querying the OMX core, V550 searches for the following roles in the list of OpenMAX components:

H.264 decode"video_decoder.avc"
JPEG decode"video_decoder.mjpeg"
MPEG2 decode"video_decoder.mpeg2"
MPEG4 decode"video_decoder.mpeg4"
VC1 decode"video_decoder.vc1"
VP8 decode"video_decoder.vp8"
VP8 encode"video_encoder.vp8"


To build example platforms containing V550, you must either install the TPIP package, or remove the dependency on FFmpeg and libvpx from the platform's sgproj file, by removing the line containing V5xx.sgrepo.

The model has the following limitations:

  • No support for HEVC and RealVideo decoders.
  • No support for 10-bit video output.
  • No profiling support.
  • No QoS support.
  • Power and Test modes are modeled only as register state changes.
