Just as a follow up to BalusC's excellent post, here is the code I am using in C#. I am chunking data manually directly to an HTTP output stream, after receiving data from the STDOUT on a process.

int buffSize = 16384;
byte[] buffer = new byte[buffSize];
byte[] hexBuff;
byte[] CRLF = Encoding.UTF8.GetBytes("\r\n");

br = new BinaryReader(transcoder.StandardOutput.BaseStream);

//Begin chunking...
int ret = 0;
while (!transcoder.HasExited && (ret = br.Read(buffer, 0, buffSize)) > 0)
{
    //Write hex length...
    hexBuff = Encoding.UTF8.GetBytes(ret.ToString("X"));
    e.Context.Stream.Write(hexBuff, 0, hexBuff.Length);

    //Write CRLF...
    e.Context.Stream.Write(CRLF, 0, CRLF.Length);

    //Write byte content...
    e.Context.Stream.Write(buffer, 0, ret);

    //Write CRLF...
    e.Context.Stream.Write(CRLF, 0, CRLF.Length);
}
//End chunking...
//Write hex length...
hexBuff = Encoding.UTF8.GetBytes(0.ToString("X"));
e.Context.Stream.Write(hexBuff, 0, hexBuff.Length);
