You haven't provided enough context here - what do you use
dec->sink_caps for? These look more like template caps anyway, but
dec->sink_caps implies that you're setting them on an instance.
So maybe your template caps are wrong; you haven't shown those at all.
Your actual buffer/pad caps you haven't shown anywhere (unless this is
what you gave above, in which case it's very obviously wrong).
- "codec_data=(buffer), " - if this parses at all, I doubt it means
anything. It certainly won't do anything useful.
- "mpegversion = (int) [0, MAX] , " - I doubt you mean to say that
your plugin supports every MPEG video codec, both current and future.
Maybe you wanted that to say "mpegversion = 4"
