t_ve_media_mpeg4_configuration_s
The
t_ve_media_mpeg4_configuration_s
structure
is
part
of
the
t_ve_media_rtp_configuration_u union of structures as defined in Appendix B.28 on Page
307. The t_ve_media_mpeg4_configuration_s structure defines media configuration options
for an MPEG-4 video algorithm task. This structure is defined in ve_defs.h and is described
below:
typedef struct{
t_ve_media_video_encoding_mode_rate_s
t_ve_media_video_quantization_param_e
t_ve_media_video_cyclic_intra_refresh_s
t_ve_media_video_pid_rate_control_s
t_ve_media_video_simple_profile_e
t_ve_media_video_mpeg4_stream_container_s
}t_ve_media_mpeg4_configuration_s;
i_frame_rate;
quant_param;
cir;
pid_rate_cntrl;
profile_and_level;
stream_container;
The elements of this structure are as follows:
Element
Definition
i_frame_rate
A structure, t_ve_media_video_encoding_mode_rate_s as defined in Appendix B.29.23 on
Page 341, which determines the rate at which I-Frames are transmitted.
quant_param
An enumerated type, t_ve_media_video_quantization_param_e as described in Appendix
B.116 on Page 544, that determines the Quantization Parameter (QP) to be used during the
encoding sequence.
cir
A structure, t_ve_media_video_cyclic_intra_refresh_s as described in Appendix B.29.16.4
on Page 331, that allows control of the Cyclic Intra Refresh (CIR) values.
pid_rate_cntrl
A structure, t_ve_media_video_pid_rate_control_s as described in Appendix B.29.16.5 on
Page 332, which allows the configuration of the MPEG-4 encoder rate control parameters.
profile_and_level
An enumerated type, t_ve_media_video_simple_profile_e as described in Appendix B.118
on Page 547, that determines the simple MPEG-4 profile to be used.
stream_container
A structure, t_ve_media_video_mpeg4_stream_container_s as described in Appendix
B.29.24 on Page 342, which defines the configuration ASCII string for the MPEG-4
complete header.
