Other Parts Discussed in Thread: DM385, TVP5158

Hello everyone

We have customized board, cpu is DM385, M3 is running IPNC RDK 3.5 firmware.

I running usecase is ENC_A8_DEC_USE_CASE, it's normal working.

I wish save H264 file to SD card, when the encode stream to A8.


can I refer which file or document ?

    Hi vic lin,

    I don't know about  availability of any document of this. But I can help you to point out the SD card dump code already available in ipnc. Only thing you need to enable the appropriate flags and resolve few dependencies.
    Please go through the ti_mcfw_ipcbits.c in mcfw_demos. Please find the below function App_streamSysVidWrite(). It will give you clearer picture of this.

    Hello ravikiran hv

    Now the encode file can be store to SD card.

    data flow is :

    ENCODE (M3-VIDEO) --> BITS OUT (M3-VIDEO) --> BITS IN(A8) --> Store to SD Card.

    By the way, I have a question the same with you

    I wanted use WDR or GLBCE library, I refer usecases: multich_quadstream_noisefilter and  multich_tristream_fullfeature the camera setting
