Enumerator
NoChain	= 1 The transcoder could not build a processing chain based on its inputs and outputs. Either the transcoder inputs and outputs are not configured properly or they are not compatible with each other. This error is returned by Transcoder.Open

UnsupportedVideoConversion	= 5 It is not possible to convert from one uncompressed video format to another. See ColorFormat.
BufferFull	= 6 One of the input/output buffers is full and cannot accept more data. Cannot accept more input through Transcoder.Push. Call Transcoder.Pull to obtain output samples.
