Hello all i have 2 .avi file sized 4.9 Gig and 12 Gig, and i want to convert them to 2 mpeg files, but when i run mencoder as usual to change these files, it works on them until it reaches the 4096 MB of input file and then it stops without any unusual message :-( Then i got the last version of mplayer sources (1-rc2) and myself compiled it with option --enable-largefiles and again converted those files with new mencoder, but no any benefits was made. The filesystems that i used for input and output files were ext3 . and the OSs were Ubuntu-7.10-amd64 and Knoppix-5.1.1 on 2 computers with same result. What is the problem , and its solutions ? How can i convert such files? thanks Send instant messages to your online friends http://uk.messenger.yahoo.com

I am sure it is not a mencoder issue per se, because I am currently working with files in excess of 30Gb (bluray disc rips) with mplayer and mencoder, with no issues. My filesystem is NTFS, however, on Windows. If I had to hazard a guess, you are bumping up against a filesystem limit (4Gb is a common limit). I don't know anything about the limits of ext3, however, so others with more knowledge will have to speak up on the issue.

AVI files do not support sizes larger than 4 GB, unless you use the (AFAIK) non-standard ODML extension. How were those files created? Can you play them with MPlayer? Can anything at all play them?

This is not a possibility, since the _input_ seems to be a problem.

At least 16GB, usually 2 TB. Though those values were from Linux 2.4 times, so they may have been extended again. Greetings, Reimar Döffinger

Afaik, this still applies, to both ext2 and ext3. Max size depends on the partition block size, and for the common 4KB bs it's 2TB, as you say. E.g. for my root partition I find $ tune2fs -l /dev/sda1 | grep "Block size" Block size: 4096 For current stable, details here http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git;a=blob;f... line 299 and following.
