``--demuxer-lavf-format=<name>``
Force a specific libavformat demuxer.
+``--demuxer-lavf-hacks=<yes|no>``
+ By default, some formats will be handled differently from other formats
+ by explicitly checking for them. Most of these compensate for weird or

``--demuxer-lavf-genpts-mode=<no|lavf>``
Mode for deriving missing packet PTS values from packet DTS. ``lavf``
enables libavformat's ``genpts`` option. ``no`` disables it. This used
