[MEncoder-users] Encoding a specific frame range

[Philippe Combes]

Hi all,

I would like to encode a movie splitted into two DVDs into one big AVI.
I found a way, combining tccat (from transcode) to mencoder ability of encoding 
from stdin (which transcode cannot do, as far as I know) This works great for 
video as well as for audio.

The problem comes when I want to select a frame range for encoding : -ss and 
-endpos options only take times as arguments. And, although I use exact times 
for my frames (according to the input frame rate of 25fps), I have never been 
able to get the exact frame range I want.
And this is important for I need to finally concatenate these ranges, encoded 
with slightly different options.

transcode offers the ability to encode an exact frame range, but not to encode 
two DVDs at the same time, and not to encode from stdin, as I said.

Is there a way to force mencoder to accurately start encoding from one frame and 
stop at another ?

Thanks in advance,

Philippe.
