FFMpeg exits with non-zero code when it is asked for version or supported formats

[nick]

Binary package hint: ffmpeg

I have Ubuntu 8.04, 64 bit edition. Normally, any unix program should return 0 when it finished without errors. But when I run "ffmpeg -version", return code is 1. Similar, when I run "ffmpeg -formats" it also return 1. This bug is fixed in latest svn version and in Ubuntu 9.04.

Looking to the source code of ffmpeg (that I get with apt-src) I found , that the problem is in show_version() and similar info functions. They print necessary information and than there is "exit(1)". It is very easy to fix this bug!

that looks fishy. What exact package version of libavcodec52 or
libavcodec51 do you have installed?

There is no libavcodec52 or libavcodec51 in Ubuntu Hardy (8.04). You can check this by ubuntu package search. And I've already written, this bug does not exist on Jaunty (9.04).

I've installed ffmpeg from standard ubuntu repositories and the same bug I found in the source package.

I've fixed the bug and make patch according to https://wiki.ubuntu.com/Bugs/HowToFix. I just replace exit(1) by exit(0) at the end of functions show_help, show_license, show_version and show_formats.

Nikolay.

Oh I see, sorry for not having read the bug properly.

I've triaged this bug accordingly.

[nick (nmn1)]

I've fixed this bug 6 month ago, why this patch is not yet included in update? Maybe I've done something wrong? Hardy is LTS release, it is used on many servers, so this is still relevant.

Hardy has seen the end of its life and is no longer receiving any updates. Marking the Hardy task for this ticket as "Won't Fix".
