  • I looked for a similar issue and couldn't find any.
  • I tried with the latest version of GPAC. Installers available at http://gpac.io/downloads/gpac-nightly-builds/
  • I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...).
