They are all provided through the API (ffprobe would not be able to 
display them if not), metadata iirc.

Please understand that avprobe and friends contain several hundred 
regressions, some of them security relevant, we therefore cannot 
support them here, please look at http://ffmpeg.org/download.html 
for supported versions, current git head is always recommended.

You should probably try to prepare a patch (against current git 
head, see above) and post it to ffmpeg-devel (or describe in 
more detail what is needed, perhaps PAT/PMT should be exported 
as metadata).

Please do not top-post here, Carl Eugen
