#24(FFmpeg:new): Error message needed when enabling drawtext filter without libfreetype

#24: Error message needed when enabling drawtext filter without libfreetype -------------------------+------------------------------------------------- Reporter: xj25vm | Owner: michael Type: | Status: new enhancement | Component: FFmpeg Priority: normal | Keywords: configure libfreetype drawtext Version: git | filter Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 -------------------------+------------------------------------------------- It would be really helpful if the configure script would issue an error message when trying to do "--enable-filter=drawtext" without adding "--enable-libfreetype". At the moment, there is no error message, and the drawtext filter doesn't get enabled. The documentation of the drawtext filter does mention then libfreetype is needed - but it would be much more helpful if the configure script would do this check. Otherwise one would have no idea why the filter silently refuses to enable with no error message. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/24> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
