--- Comment #23 from Oleksij Rempel <bug-track at fisher-privat.net> ---
Hi,
this patch introduced an regression on two pass encoding. Some DVDs will cause
caps renegotiation just at the end of stream and as result corrupted multipass
cache.
The issue looks like fallowing:
1. start of stream
2. frames
.........
5. caps reinit.
6. frames
6. end of stream.

Since reinit will send NULL frame image to the encoder, it will create EOS
header for the multipass cache file. Next frame will reinit multipass file and
actual end of stream will create one more header with EOS and wrong count of
frames.
