[theora] Possible interference between two directshow encoder/mux instances

[Andrew Bisson]

I have an application written in c# which uses two instances of the
theora encoder in a single filtergraph. Each one is followed by an ogg
multiplexer for output to separate files.  When I run the filtergraph
the smaller video's buffer is intermittently written to the start of the
larger video's buffer.  I am using the latest filters from
opencodecs_0.84.17338.exe and the smaller video is coming from separate
preview filtergraph via a GMFBridge component that connects the
preview/render graphs.  There are currently no clear indications as to
where the interference is occurring but a previous version using wmv
encoders did not exhibit this problem so it seems possible that it lies
in the encoder/mux.  Is it possible that the encoder instances are
sharing memory that they should not be?

 

Thanks,

Andy
