I've been tracking the cause of the channel change slowness in my system (takes
around 8-12 secs). For now, I've managed to find two slow function
calls during the
channel change, both at AvFormatDecoder::OpenFile().
The calls to av_find_stream_info() and to ScanStreams() together take
secs of the channel change time.
Any ideas why this is the case? I have a reasonably fast computer (P4
those functions don't seem to be overly complicated. Any ideas how to
calls in case of DVB LiveTV?
Thanks in advance,
