I was not able to reproduce the problem. There might be a problem your build or something with your version of libavformat/codec. Or, possibly, you do not have the resample plugin. Look for libmltresample.so where your mlt plugins are located, e.g. $prefix/lib/mlt. This plugin requires that you configure MLT with --enable-gpl or --enable-gpl3 to make a GPL build of MLT. The fallback FFmpeg-based audio resampler in MLT is LGPL, but it is only compatible with libavcodec version < 54.26.0. IOW, at the moment we do not have a LGPL audio resampler for cutting edge versions of FFmpeg or Libav. These projects have diverged with respect to the libs. I may revisit this soon as I have other work to do in this module. -- +-DRD-+ ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
