Yes, I've put the chat with tim and slomo because it was tricky.
The important point imho could be:
| toso slomo: right, my point was that I would like to list the
| h264 decoders that are available and I was using `video/x-h264,
| stream-format=3Dbyte-stream` as input for
| gst_element_factory_list_filter() .. and avdec_h264 is the one
| not showing because it needs the aligment
So, the problem I had at that time was exactly that using
stream-format would prevent loading avdec_h264 as viable option.

If you test this and it lists & works with avdec_h264, I think it
is fine too.
Cheers,
Victor
