[x264-devel] Passing custom data through the encoder.

[Dan Rosen]

When using the API, is there any way to pass data arbitrary frame data
through the encoder so that we can relate information from the source YUV
frame to the encoded frame?  We could create a custom unregistered user data
SEI, but then we would need to manually remove this SEI from the list of
encoded NALs.  Was hoping there would be an easier and lower overhead
technique.
