[FFmpeg-user] Size limitation when converting avi to mpeg

[Eamonn McEvoy]

I am trying to convert an avi file to mpeg, but ffmpeg is giving me these error messages, 'buffer underflow' and 'packet too large'

The command I am using is :

ffmpeg -I input.avi -s 2592x2106 -b 1200 output.mpg


1.  Dimensions of video - are there any limitations?

I have noticed that if I take a video with smaller dimensions it seems to work ok, Is there any way to accommodate files with large large dimensions like this?


2.  Frame rate - can ffmpeg pad out videos?

I also have issues with certain frame rates, the error message tells me that only certain frame rates are supported by the mpeg1 format, can I get ffmpeg to pad out my avi file to account for this?


3.  File size - are there any limitations on the max file size that can be converted?
Thanks,
Eamonn
