Description

Recording x11grab with the below command works on x86_64 Arch Linux and Ubuntu Lucid, but fails with 32-bit Natty.

Looks like a regression:

However, re-encoding from a file and not x11grab seems to work as expected.

This bug has been reported and confirmed by several users on ubuntuforums.org. It needs some developer attention as it is still reproducible. Please fix it, and thanks in advance.

comment:2 Changed 5 years ago by cehoyos

  • Status changed from new to open

Does not using libx264, but an internal encoder work?
Does using another (non-lossless) preset work?

If you believe this is a regression, please find the version

comment:3 Changed 5 years ago by verb3k

Other non-lossless presets and internal encoders have been reported to be working properly with x11grab. It only seems to be an issue with the lossless presets.

Is the problem also reproducible without x11grab?

comment:5 Changed 5 years ago by llogan

Apparently it is now reproducible without x11grab, although I'm fairly sure I tested for this when I submitted the bug report:

Does it work on 64bit?

comment:7 Changed 5 years ago by llogan

Yes, it still works as expected on 64 bit:
