FLV Encoder SDK Description

A developer tool to create Flash Video Files.

FLV Encoder SDK is a DLL to create Flash Video Files. You can use it in programs written in C++, Delphi, C# and more. Create FLV in your programs with FLV Encoder SDK. Simple API. Samples are included.

[ C++ ]

void CALLBACK WriteCallback(LPVOID lpParam, LPCVOID lpData, DWORD nLen)
{
WriteFile((HANDLE)lpParam, lpData, nLen, NULL);
}

...

FTVIDEOINFO video_info;

video_info.dwCodec = FT_VIDEOCODEC_SCREENVIDEO;
video_info.dwWidth = 0x100;
video_info.dwHeight = 0x100;

FTAUDIOINFO audio_info;

audio_info.dwFormat = FT_SOUNDFORMAT_UNCOMPRESSED;
audio_info.dwRate = FT_SOUNDRATE_44KHZ;
audio_info.dwSize = FT_SOUNDSIZE_16BIT;
audio_info.dwType = FT_SOUNDTYPE_STEREO;

FTFLVSTREAMINFO info;

// if you don't want to place any video into a flv, you can pass NULL
info.lpVideoInfo = &video_info;
// if you don't want to place any audio into a flv, you can pass NULL
info.lpAudioInfo = &audio_info;

info.lpWriteDataCallback = &WriteCallback;

HANDLE hFLVFile = CreateFile( ... );

info.lpParam = hFLVFile;

HFTFLVSTREAM hFlvStream = ftFlvStreamCreate(&info);

Prepare Screen Video Encoder:
[ C++ ]

HFTSCREENVIDEOENCODER hScreenVideoEncoder = ftScreenVideoEncoderCreate(0x100, 0x100, 16);

Compress (encode) and write video data:
[ C++ ]

// OnVideoData(const char* data, unsigned int size, unsigned int timestamp)

LPCVOID lpData = 0;
DWORD cbBytes = 0;

ftScreenVideoEncodeFrame(hScreenVideoEncoder, data, size);
ftScreenVideoGetEncodedFrame(hScreenVideoEncoder, &lpData, &cbBytes);
ftFlvStreamPutVideoData(hFlvStream, lpData, cbBytes, timestamp);

Write raw audio data:
[ C++ ]

ftFlvStreamPutAudioData(hFlvStream, lpAudioData, nLen, nTimeStamp);

Destroy the video encoder and flv stream:
[ C++ ]

ftScreenVideoEncoderDestroy(hScreenVideoEncoder);
ftFlvStreamDestroy(hFlvStream);
