That would be a bug somewhere. You can set the G_DEBUG=fatal_warnings
environment variable and then run your application in a debugger such as
gdb, which will then abort at the warning, and then you can see from the
stack trace where it comes from.

How well trick modes and especially backwards playback will work depends
a lot on the exact circumstances: what is the exact playback pipeline,
which demuxer or parser is used, what decoders are used, etc.

Don't think the SKIP flag is implemented widely yet.

You probably always want to do a FLUSHing seek in a player application.
If your seek is not flushing, there may be a longer delay, because there
may still be data in queues and elsewhere that needs to be processed. If
a FLUSHing seek doesn't work in some circumstances, that needs to be
fixed.

 Cheers
