- OMX codec for WebRTC / John Lin
- successful 2 way video communication
- issues found
- serious frame drop due to low min bitrate parameter. Can be avoid by increasing the number.
- bad image quality especially when high motion. Can be avoid by increasing encoding bitrate parameter.
- high decoder CPU usage (~30%) due to OMX buffer memcpy(~28ms for ~470K data). Need to use graphic buffer instead.
- video freeze because of decoder time-out. Need further investigation.
