FileRd->Dec->FileWr

Hi,

I was able to run the McFW test FileRd+Decode+Display test.

For our usecase we need the output in a separate file.

So I modified the McFW test to dump the decoded output to file.  I modified the link setup in such a way and the below code shows my modifications.

===============

But I am not able to get any buffers from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0. 

A little about my setup:

1. DM8168 based and with DVRRDK 3.5

2. I am using 256MB confuguration in the bootcmd. "setenv bootargs 'console=ttyO2,115200n8 root=/dev/nfs nfsroot=107.108.212.53:/home/user/dm8167-software/tftphome/rfs_816x,nolock  mem=256M vram=20M notifyk.vpssm3_sva=0xBEE00000 ddr_mem=1024M  ip=dhcp' ; "

I see that when i run the test the links are successfully created.

I am getting the following output when i print the buffer statistics:

The demo_ini folder has the following in config file:

[file00]
path = /opt/video_MAIN_mpeg4.m4v
width = 176
height = 144
enable = 1
codec = mpeg4
numbuf = 1
displaydelay = 0

======

But I am not able to get any buffers from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0. 

This file was successfully displayed in the default McFw dec+disp test.

What am i doing wrong.?

    My receive thread is as follows:

    rxvthread()

    {

    VIDFrame_BufList bufList;

    bufList.numFrames = 0;
    status = IpcFramesInLink_getFullVideoFrames(SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0,
    &bufList);

    OSA_assert(0 == status);
    if (bufList.numFrames > 0)
    {

    printf("bufList.numFrames = %d\n", bufList.numFrames);

    status = IpcFramesInLink_putEmptyVideoFrames(SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0,
    &bufList);

    }

    }

    with this i am getting one buffer as output from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0. but not afterwards,

    What is the reason why i am getting only one frame from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0.?

    when i print the info of only one received frame from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0,

    I get the the phyAddr[0][0]  and virtAddr[0][0] to be NULL

    "bufList.numFrames = 1

    [host] CHAINS_IPCFRAMES:VIDFRAME_INFO:chNum:0 fid:0 frameWidth:176 frameHeight:144 timeStamp:0 virtAddr[0][0]:(nil) phyAddr[0][0]:(nil) [m3video]

    "

    Why does this happen?

    You should set ipcFramesOutVideoPrm.baseCreateParams.notifyPrevLink = TRUE;

    Also if you want to export video frames to A8 make sure tiler is disabled in decLink prm.

    Also set the decLink numOutBufPerCh to 5 (incase you are modifying default value)

    Thanks Badri very much for your input.  You really saved a lot of my debugging time.

    i am now able to get the buffer from SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0.

    Now i am testing the output with the  standard input testvector from theRDK "airshow_p176x144.h264".

    I am using ddrmem=2GB and linuxmem=512MB configuration.

    The buffer's phyAddr that i receive are from SR2 region(between 0x96000000->0xBE000000).

    As discussed in the forum, I memory mapped the address and wrote to the file as follows:

    ---------

    frameSize = 38016; /* 176(width) * height(144) *1.5*/
    fileIdx = pBuf->channelNum;
    status = OSA_mapMem((UInt32)(pBuf->phyAddr[0][0]), frameSize, &pMemVirtAddr);

    OSA_assert((status == 0) && (pMemVirtAddr != NULL));

    if (fwriteEnableChannelBitmask & (1 << fileIdx))
    {
        write_cnt = fwrite((Ptr) pMemVirtAddr, sizeof(char), frameSize,fpBuf[fileIdx]);

       OSA_assert(write_cnt == frameSize);

    }
    status = OSA_unmapMem((Ptr) pMemVirtAddr,frameSize);

    ------

    "pBuf" above corresponds to (&(bufList.frames[i])) where buflist was obtained from IpcFramesInLink_getFullVideoFrames() call

    I used the standard input testvector from theRDK "airshow_p176x144.h264".

    Though i got some output, When i compared against the reference airshow_p176x144.yuv,  there are discrepencies.

    I was also not able to play the output in the yuv player.

    I assumed the output is yuv-420 in the yuv player and i am using the  pixel sizes= 1.5 to calculate the framesize.

    Is the output in a different yuv format or am i missing any other configuration?

    What am i doing wrong?

    Also is it okay to receive the output decoded data from Video-M3 using [SYSTEM_VIDEO_LINK_ID_IPC_BITS_OUT_0-> SYSTEM_HOST_LINK_ID_IPC_BITS_IN_0 ]

    links instead of [SYSTEM_VIDEO_LINK_ID_IPC_FRAMES_OUT_0-> SYSTEM_HOST_LINK_ID_IPC_FRAMES_IN_0]?

    The output of decoder is in NV12 format. ie. YUV420SP . Y will be in a separate buffer and UV will be in a separate buffer. You can google for details on the format but the issue you should not copy the buffer as w x h x 1.5 from pBuf->phyAddr[0][0] .

    Copy should be

        pitch[0] x h from pBuf->phyAddr[0][0]

        pitch[1] x h from pBuf->phyAddr[0][1].

    - No you should uses only IpcFrames and not IpcBits to export video frames.

    1. How do i get pitch[0] and pitch[1] values?

    (We were setting the pitch values "ipcBitsOutHostPrm.inQueInfo.chInfo[i].pitch[0]= 0".

     I guess that says it to take default pitch values.

    I tried with pitch[0] with framewidth and pitch[1] as framewidth/2. It didn't help.)

    2. For the FileRd->Scaler->fileWr usecase,  should i  get YUV buffers in this way?

    thanks for replying.

    VIDEO_FRAMEBUF_S.framePitch has the pitch. pitch[0] and pitch[1] will be same when using YUV420SP format. ipcBitsOut pitch is unrelated to decoder output buffer pitch.

    2. For the FileRd->Scaler->fileWr usecase,  should i  get YUV buffers in this way?

     - Some scalers support YUV420SP output format and some support only YUV422I format. It depends on the scaler path Id you are using.
