I'm new to encoding videos and am pretty green at this. I've spent the
better part of the past 4 days learning everything I can before asking
any questions. I'm a php programmer that has been thrown to the wolves
on the video side of things.
I'm attempting to do a 2 pass encoding using libavcodec. On the man page
it has:
vpass=<1-2>
Activates internal 2pass mode (default: disabled):
1: first pass
2:
Then below it are examples such as:
vbitrate=<value>
specify bitrate (pass 1/:2) in...
Does (pass 1/:2) mean specify it on both passes, and if it does not
state it, only on pass 2? I also get this, "[flv @ 0x85b7468]Error:
2pass curve failed to converge". I've searched this error much with few
results. I've played around, solved the problem, but have no idea why.
Any input would be very much appreciated.
Sean
