Description:

On arch linux, "synfig -t ffmpeg" does not work at all, because it passes ffmpeg the -loop_input option which is no longer supported. It should instead use "-loop 1".

A more detailed bug report has already been filed upstream:

http://www.synfig.org/issues/thebuggenie/synfig/issues/345

However, because arch tends to use later versions of software than other distributions, it may be that the upstream bug report sits there for a while until other linux distributions update their ffmpeg versions.

In the mean time, it would be nice if the software actually worked on arch. Hence, I'm attaching a patch to the arch source package that fixes the problem. All I've done is add the patch found in the above synfig bug report, which unfortunately has been sitting there unassigned since February.

To be clear, of course I would rather see this bug fixed upstream, but the reality is that you guys (arch) are way more responsive than other people about bug reports. Hence, I'm hoping you can temporarily fix it in arch by accepting the attached patch, thereby saving arch users some frustration.

Additional info:
* package version(s)

synfig-0.64.0-1

* config and/or log files etc.


Steps to reproduce:

Just run "synfig -t ffmpeg anyfile.sifz"--you will see ffmpeg dies and then synfig just complains of a broken pipe over and over, ultimately producing no output file.
