[vlc-devel] Playing only I-frames

Hello, all ...
I would like to make VLC play only I-frames when told to. However, the
code in $vlc_root/modules/demux/mpeg/ps.c -- the Demux() function via
function pointers to ReadPS() and DemuxPS() -- deals with MPEG packs
i.e. it aligns itself on the pack header, reads the pack and aligns
itself on the next pack header to read the next time through the loop.
So it appears that packs are the things that are stuffed into the FIFO
here, and the decoder module hands this stuff off to ffmpeg or whatever
to do the heavy stuff i.e. anything lower than a pack is not a VLC
thing, but an ffmpeg / libavcodec thing. Is this correct?
