problems of FileRead->decode->FileWrite in DM8168

Hi Badri,

      Thanks for you replay.i have read the  post you have mentioned ,but i still cannot understand how  to get the decode output data.could you give me some advise.

      now i have  a question in the directory of DVRRDK_04.00.00.03/dvr_rdk/demos/mcfw_api_demos/mcfw_demo there some function to realize  the bit  file write function or frame write function.

       In the file of demo_vcap_venc_vdis_bits_wr.c the function  of Venc_getBitstreamBuffer() to get the bit buf data and write to the file .

      In the file demo_vcap_venc_vdis_ipc_frames_exch.c the function of  Vcap_getFullVideoFrames() to get the frame buf data and write to the file.

      But now ,from above link structure ,we donnot use the vcap,and venc,so i donot know how to get  the file write data .

      Thanks vrey much.

Hi,

       Above the following links i want to realise the FileRead->Decode->FileWrite Usecase ,i used it by follow link structure.

    Now,i have the following problems:

       i mearsue the recvived frames in IpcFramesInHost and IPC_IN(VPSS) side ,it only receive the first few frames of data but i use the demo of VdecVdis the link of IPC_IN(VPSS) can receive lots of the frame date .and attatched is the log txt mearsured in different link structure.

         I donnot know what the problem, Could you give me offers or sugesstions,thansk a lot.

Ensure you are freeing the buffers received in ipcFramesInHost back.

Hi  Badri,

   Thanks for you replay ,after the link structure finishec ,i call a thread function  to write data to a file which is opened. and i consider the date is come from the  ipcFramesInHost  side.

 The main thread function and my commments are follows:

 VIDEO_FRAMEBUF_LIST_S bufList;

  while (FALSE == thrObj->exitFramesInOutThread)       //it will always run if the thread is start

  {

    status =  Vcap_getFullVideoFrames(&bufList,0);  //it get a bit buf from the link of  ipcFramesInHost  side

   Vdectohost_ipcFrameFileWrite(&bufList);    //write  the frame date to file

    status = Vcap_putEmptyVideoFrames (&bufList);  //freeing the buf in the link of  ipcFramesInHost  side

}

     1. how can i do to free the buffers received in  ipcFramesInHost back.

    2. I think  the function of Vcap_putEmptyVideoFrames () realize  freeing the buffers received in ipcFramesInHost

is that right.

    3. Between different link  what mechanism is based on the data transfer.

      Thanks a lot.

ouyang.
