    Hi Huang,

    For H263 support, you can check here:

    Hello

    We are actually using the OMX  encode example in the ezsdk5_05_02_00 to edit and implement a rate control algorithm.Can i use xdas structures ,IVIDENC and IH264ENC STRUCTURES also provided in the ezsdk package to

    write and make encoder configuration settings?

    Would the DM8168 h264 encoder properly understand the difference between omx library structure settings and ih264enc structure settings?

    for example :if i set the target bitrate using the the omx library structure and set the framerate using the XDAS library structure the encoder would properly get configured or am isupposed to stick to one library for coding?

    Thank you

    Hi Rutuja,

    EZSDK 05.05.02.00 already has TI specific OMX index to support  dynalically configure the encoder.

    You can change bitrate, resultion etc dynamically using OMX_SetConfig.

    Refer omx_venc.c how the OMX index is translated XDM interface.
