Anybody comes to know the correct command to generate multiple outputs 
with different resolutions ??

Ah, cehoyos, could you elaborate? Are you saying that the command line I posted
does the right thing in not producing the result I want? If so, what do I need
to change in the command so that both videos are scaled in the intended way?

You say that 'and if several sizes are specified, the last one should be
used'. Yes, I agree to that for the case where I specify multiple filters for
the same output file. But my goal here is to specify different filters for
different output files.

Unfortunately I do not know the details, but I think there is always
only one filter chain, if you encode to multiple files you must
explicitly split the data and pass the output of different scalers
to different streams.
I.e. you must specify a vf that results in something like this
input #0.0 --- scale size a --- output #0.0
\
 - scale size b --- output #1.0

Don't ask me how to do that, I have no idea.
It should be in some documentation though...

I would assume the second output file should use the source's dimensions if no
filter is specified (and if several sizes are specified, the last one should be
used).

2010-06-14 Thread blindbunny 

New submission from blindbunny ffmpegbugs.10.noonee...@spamgourmet.com:

My goal is to recode an input video in one go into two/multiple output videos of
different frame sizes. Due to issue1957 I use the libavfilter filters for that.
The problem is that only the last specified -vf option is applied to the first
output file. The remaining output files do not get any of the specified -vf
filters applied.

As you can see, the -vf options are intended to create sd.mkv with 120x90 and
hd.mkv with 240x180, but the result is sd.mkv with 240x180 and hd.mkv with the
resolution of the source material of 720x576 - at least I hope I'm using the
command line options correctly here...
