MMCodecs ABSTRACT Texas Instruments TMS320DM365 H.264 video encoder is a flexible implementation of the H.264 video encoder standard. It supports various profiles and features, each of which can be independently selected, set or controlled. This flexibility enables the TMS320DM365 H.264 video encoder to be used in a variety of different applications. This application report lists the different parameters that can be set to control the operation of the TMS320DM365 H.264 video encoder. Recommended values of the parameters for several applications scenarios, video conferencing, video security, video surveillance, video broadcast, video streaming, storage, local playback and digital video recorder DVR are provided. These recommended values enable the optimal usage of the video encoder for these application scenarios. 1 Introduction DM365 is a digital multi-media system on-chip comprising an ARM926 host processor, two co-processors and various peripherals. The DM365 also has a video front-end hardware block that enables seamless interface to most additional external devices required for video applications. The H.264 video encoder, which is a popular video coding algorithm enabling high-quality multimedia services even on limited bandwidth network, has been implemented on DM365. The programm
