ffmpeg | branch: release/2.2 | Nicolas George <geo...@nsup.org> | Fri Jul 18 10:34:39 2014 +0200| [f7b147548e768aa36acec9f752fcbd001d9e03c5] | committer: Michael Niedermayer
ffmpeg_filter: refuse to configure input without a decoder. The decoder is necessary in order to filter frames. This makes the error message clearer in this case: currently, it will usually fail because the pixel or sample format is not defined and is converted into "(null)" (non-portable). Enhance trac ticket #3779.
