Bug Description

Binary package hint: ffmpeg

ffmpeg has an option '-x11grab' which enables it to record the desktop to a video file. This is commonly used by the community making screencasts on Ubuntu as it produces high quality video files with little computational overhead.

ffmpeg is compiled with the --enable-x11grab option enabled, but there appears to be a missing dependency on libxfixes-dev (in main) (see comment 3, below). As a result this feature which is compiled in is broken. It worked fine in Lucid, so this feature has regressed.

Adding the necessary dependency and rebuilding ffmpeg fixes the issue completely.

This is trivially fixed by adding the missing Build-Depends for libxfixes-dev to ffmpeg's debian/control

ACK. (side note: we don't use non maintainer uploads, so you can just make it a ubuntu3 version instead of ubuntu2.1).

StefanPotyra (sistpoty) wrote :

ok, uploading as well. I've changed the version number and removed "Non-maintainer upload" from changelog, hope that's ok with you :).

Good catch, thanks. I'll upload a fix for ffmpeg-extra in a minute.
