Hi,
Is there anyway to add a h264 NAL (SEI Timecode) unit to an existing stream
without access libavcodec source (i.e. only linking against the DLL)?

I don't think so.
AFAICT, the H.264 encoders don't support SEI writing in any released

extract SPS/PPS etc and add a NAL unit. I know x264 adds SEI User messages
