saving H264 stream to local file failed

Bo Wang1

Hi,

I am using IPNC RDK 3.8 on DM8127. I modified the ENC_A8_DEC usecase to save H264 stream to local file. Related source code is as the following.

Void *MultiCh_ipcBitsMain(Void *prm)
{
    UInt32 i;
    OSA_DmaCopy1D copy1D;
    Bitstream_BufList fullBitsBufList;
    Bitstream_BufList emptyBitsBufList;
    IpcBitsOutLinkHLOS_BitstreamBufReqInfo ipcReqInfo;

    OSA_printf("Entered IPC Bits Handler function\n");
    gIpcBitsThObj.exitTh   = FALSE;
    gIpcBitsThObj.exitDone = FALSE;

    //unsigned char const start_code[4] = { 0x00, 0x00, 0x00, 0x01 };
    FILE  *outFile  = NULL;
    FILE  *outFile2  = NULL;
    UInt8 *buf = NULL;
    UInt32 n   = 0;

    if(outFile == NULL)
    {
    	outFile = fopen("8127Test.h264", "w");
        if (outFile == NULL) {
    		OSA_printf("Failed to open file for writing\n");
                exit(0);
        }
    }

    if(outFile2 == NULL)
    {
    	outFile2 = fopen("8127Test.hdr", "w");
        if (outFile2 == NULL) {
    		OSA_printf("Failed to open file for writing\n");
                exit(0);
        }
    }

    while(gIpcBitsThObj.exitTh == FALSE)
    {
        OSA_semWait(&gIpcBitsNotifySem,OSA_TIMEOUT_FOREVER);

        IpcBitsInLink_getFullVideoBitStreamBufs(gIpcBitsInHLOSId,&fullBitsBufList);

        if(fullBitsBufList.numBufs > 0)
        {
            for(i = 0;i < fullBitsBufList.numBufs;i++)
            {
                ipcReqInfo.numBufs       = 1;
                ipcReqInfo.minBufSize[0] = DEC_MIN_BUF_SIZE;

                /* Wait till empty buffer is got from IPC Bits Out link */
                do
                {
                    IpcBitsOutLink_getEmptyVideoBitStreamBufs(gIpcBitsOutHLOSId,&emptyBitsBufList,&ipcReqInfo);
                    OSA_waitMsecs(10);
                }while(emptyBitsBufList.numBufs == 0);

                /* Copy bitstream */
                emptyBitsBufList.numBufs = 1;
                emptyBitsBufList.bufs[0]->channelNum = fullBitsBufList.bufs[i]->channelNum;
                emptyBitsBufList.bufs[0]->fillLength = fullBitsBufList.bufs[i]->fillLength;
                emptyBitsBufList.bufs[0]->timeStamp  = fullBitsBufList.bufs[i]->timeStamp;

                if(gDmaHndl.chId == 0xFF)
                {
                    memcpy(emptyBitsBufList.bufs[0]->addr,
                           (fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset),
                           fullBitsBufList.bufs[i]->fillLength);
                }
                else
                {
                    copy1D.srcPhysAddr = (unsigned long)CMEM_getPhys(fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset);
                    copy1D.dstPhysAddr = (unsigned long)CMEM_getPhys(emptyBitsBufList.bufs[0]->addr);
                    copy1D.size        = fullBitsBufList.bufs[i]->fillLength;
                    OSA_dmaCopy1D(&gDmaHndl,&copy1D,1);
                }

#if 1
		buf = fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset;
		if (fwrite(buf, fullBitsBufList.bufs[i]->fillLength, 1, outFile) != 1) {
    			OSA_printf("Failed to write data to file\n");
                	exit(0);
                }
#endif
		fprintf(outFile2, "%d, ", fullBitsBufList.bufs[i]->fillLength);
		n++;

		if(n % 100 == 0)
    			OSA_printf("received %d frames.\n", n);

		if(n == 3000)
		{
			fclose(outFile);
			fclose(outFile2);
			exit(0);
		}

                IpcBitsOutLink_putFullVideoBitStreamBufs(gIpcBitsOutHLOSId,&emptyBitsBufList);
            }
        }

        IpcBitsInLink_putEmptyVideoBitStreamBufs(gIpcBitsInHLOSId,&fullBitsBufList);
    }

    gIpcBitsThObj.exitDone = TRUE;

    OSA_printf("Exiting IPC Bits Handler function\n");

    return NULL;
}

When I run the program, about 2500 frames are saved successfully. Then this thread seems to be locked and no more output is seen. The log is like this:

In other words, I can not save 3000 frames continuously. What is wrong?

I have done another try.

I set frame length to a constant value like this,

		buf = fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset;
		if (fwrite(buf, 10000, 1, outFile) != 1) {
    			OSA_printf("Failed to write data to file\n");
                	exit(0);
                }

Then I run the program again. The problem is gone! The thread is no longer locked and 3000 frames are saved successfully. How to explain this?

I am not sure that's the right place to put file saving function.

I modified demos/mcfw_api_demos/multich_usecase/ti_mcfw_ipcbits.c: App_streamSysVidWrite(),

I have no problem with saving h264 and mjpeg streams.

Hi，Hongfeng

Thanks for your response. I will try it in your way.

Hi, Hongfeng

Which version of IPNC RDK and which usecase are you using? Are you Chinese?

0 Hongfeng Wang over 9 years ago in reply to Bo Wang1

Genius 3925 points

I use IPNC RDK3.8 too. I would be glad to help if you have more difficulties.

Hi, Hongfeng

My problem has not been solved yet. I guess you are Chinese according to your nick name. Am I right? If so, maybe we can communicate in Chinese more conveniently.

0 Bo Wang1 over 9 years ago in reply to Hongfeng Wang

I modified /opt/ipnc/autorun_ipnc.sh from

./boot_proc 1&
sleep 2
./boa -C /etc &

./boot_proc 5&
sleep 2
./boa -C /etc &

Then issue is gone.

Now my new question is what function the operation of boot_proc serve?
