    Decode display use case in dvr rdk package is the reference for an NVR product where you receive encoded content from network and use DM816x for decode & display / storage / stream out.

    Other use cases are for DVR where capture, encode, storage, preview delayed decode / playback are done.

    Latest DVR releases include a complete NVR GUI Reference Application.

    but i found that in the usecases\ti81xx multich_vdec_vdis.c ,it is read bits from .264 file user give it in the filesystem.

    is that this demo in your saying?please check.

    Please look at functions defined in dvr_rdk\dvrapp\ti816x_nvr\app\src\app_rtsprx.c especially streamRecvProc(), this will give you idea how app is interacting with live555. This is just starting point you need to grep around to understand complete call flow.

    multich_vdec_vdis.c code is the decode-display use case which does not really know about the input source.

    Non-GUI Demo (console) based does file read - decode - display.

    NVR GUI does network read - decode - display. Live555 is already part of NVR GUI Reference App (dvrapp/ti816x_nvr).

    hi

    i know your meaning。

    that is to say，the dvr usecase  multich_vdec_vdis.c can not use if i want to receive bits from net use live555，then decode and display。

    in my case，that is ， receive bits from net use live555，then decode and display，

    then i must use gui demo in ti816x_nvr. this demo do not use  multich_vdec_vdis.c in the dir dvr_rdk/mcfw/src_linux/usecases/ti81xx

    is it?

    note:i use DVR 4.00 on 8168
