Gstreamer and MPEG TS Constant Bit Rate

Hi Tim,
Thanks.  That could be an interesting option but I don't have the coding skills to implement something like that so I was just trying to see what existing solutions exist with Gstreamer for CBR without heavy encoding.
Thanks, Tom

Or maybe it would be possible to just add padding, if the original
stream is "fairly constant" and can be configured to encode to slightly
less than required? (Not that we support that either at the moment, as
far as I know)

Cheers
