[FFmpeg-user] ffmpeg recording problem while

[Mehmet Ali]

Hi there,
I demux from an ip cam h264 video stream and draw it on screen. It is working well but when i record the same stream ( just demux and record not decode) ffplay.exe cant play the file..Why this code doesnt work? If i have to write somethings like header before frames to file please clarify me.. Thank you for your help.. 
My Code like this:
        //create file	pVideo=fopen("VideoTest.264","ab+");		//start a loop and using demux of stream capture video and decode by decoder of stream			if(!stream.mDecoder.AllocateFrame(frame))	{		TRACE("frame Allocate error\n");		return 0;	}		if(!stream.mDecoder.AllocateFrame(scaledFrame))	{		TRACE("scaledFrame Allocate Error\n");		return 0;	}
	if(!stream.mDecoder.InitializeFrame(scaledFrame,stream.mDemuxer.mStreamInfo.mWidth,stream.mDemuxer.mStreamInfo.mHeight,mPxl))	{		TRACE("scaledFrame İnitialize Error\n");		return 0;	}	DWORD start,end,onesecst;	int framerate=0;	bool startmes=true;	CString frm;	bool isRun=true;	int ret=-1;
		static int frameno=0;	while(isRun) 	{		if(startmes)		{			onesecst=GetTickCount();			startmes=false;		}		start=GetTickCount();				ret=WaitForSingleObject(stream.mHandletoStop,1); //HACK timeout ile çıkmalı reset event çağırılınca		if(ret==WAIT_OBJECT_0)		{			TRACE("Exit event fired!.\n");			isRun=false;		}
		memset(videoBuffer,0,256*1024);
		if((encodedFrameSize=stream.mDemuxer.GetFrame(videoBuffer))<0)		{			TRACE("GetFrame Error\n");			break;		}		if(!stream.mDecoder.Decode(videoBuffer,encodedFrameSize,frame))		{			TRACE("Decode error\n");			continue;		}
		if(pthis->WillSend)		SetEvent(pthis->SendToCMS);
		int totalWritten=0;		int rest=encodedFrameSize;		DWORD written=0;        while(rest>0)        {            written=fwrite(videoBuffer+totalWritten,1,rest,pVideo);            if(written<0)                break;
            totalWritten+=written;            rest-=written;        }		if(!stream.mDecoder.Scale(frame,scaledFrame,stream.mDemuxer.mStreamInfo.mWidth,stream.mDemuxer.mStreamInfo.mHeight,mPxl))		{			TRACE("scale error\n");			break;		}				stream.mDrawer->Display(scaledFrame->data[0],stream.mRect);
		end=GetTickCount();		int abc=end - onesecst;				framerate++;		totalEncodedSize+=encodedFrameSize;		if(end - onesecst>=1000)		{

			frm.Format("Frame Rate:%d\n",framerate);			pthis->sttcFrameRate.SetWindowText(frm);				frm.Format("Bit Rate:%lu kBps\n",8*totalEncodedSize/(1024));			pthis->sttcBitRate.SetWindowText(frm);			startmes=true;			framerate=0;			totalEncodedSize=0;		}

			}
I used to play file with ffplay this string
E:\ffmpeg\20130703\bin>ffplay.exe -f h264 -analyzeduration 258522508 -probesize958852258 VideoTest.264
ffplay.exe return some warnings
