I am using the VP8 .NET library to convert a video stream from my laptop webcam and i would like to store it in a webm file (no audio needed). To do so, I'm using the code provided as example in the documentation of the library and I added a few lines of code to write the encoded stream to a file. Here's the code:
class EncodingSession
{
private readonly VP8.Encoder Encoder;
static FileStream fs = new FileStream("provavideo.webm", FileMode.CreateNew);
BinaryWriter w = new BinaryWriter(fs);
public EncodingSession(int width, int height, int fps)
{
Encoder = new VP8.Encoder(width, height, fps);
}
public byte[] Encode(Image frame)
{
Encoder.ForceKeyframe();
byte[] array = Encoder.Encode((Bitmap)frame);
w.Write(array);
return array;
}
}
However, this does not produce a valid webm file, probably because the webm headers are missing. My question is: how do I add a valid webm header (if this is really what is needed)? Are there other stuff needed to be added to my file?
