Single images can theoretically be perfectly supported in gmerlin-avdecoder. They have one video stream with framerate_mode == GAVL_FRAMERATE_STILL and one frame. I think hacking together a simple "demuxer" for png, jped and maybe tiff can be done quite easily. I'll see what I can do. Burkhard P.S. and good to know, that someone besides me still uses gmerlin-avdecoder. I'm still working on gmerlin, but mostly for my personal enjoyment. ------------------------------------------------------------------------------ Transform Data into Opportunity.
