That's much clearer, thank you. How about (adding the new fields at the end, so we can print the format info as we go through the file)
Code:
awk '
FNR == 1        {FILENR++
                }

FILENR <= 2     {CNT++
                 CHFM[CNT] = $1
                 RGEX[CNT] = $2
                 DOTS[CNT] = $3
                 FMTS[CNT] = $4
                 FIDX[CNT] = FILENR
                 next
                }

                {printf "%s", $0
                 for (j=4; j<=5; j++)   {TMP = $j
                                         PTR = 0
                                         for (i=1; i<=CNT; i++) if (match (TMP, CHFM[i]))       {printf "|%s|%s|%s|%s|%s", PTR + RSTART, RLENGTH, CHFM[i], DOTS[i], FMTS[i]
                                                                                                 TMP = substr (TMP, RSTART+RLENGTH)
                                                                                                 PTR += RSTART + RLENGTH - 1
                                                                                                 TYP[j-3,FIDX[i]]++
                                                                                                }
                                        }
                 for (j=1; j<=2; j++) printf "|%s|%s", TYP[j,1], TYP[j,2]
                 print ""
                 split ("", TYP)
                }

ogmdemux

OGMDEMUX(1)							   User Commands						       OGMDEMUX(1)

NAME

       ogmdemux - Extract streams from OGG/OGM files into separate files

SYNOPSIS

       ogmdemux [options] inname

DESCRIPTION

       This program extracts all or only some streams from an OGM and writes them to separate files.

       inname Use 'inname' as the source.

       -o, --output out
	      Use  'out'  as  the  base  for  destination  file  names.  '-v1', '-v2', '-a1', '-t1'... will be appended to this name. Default: use
	      'inname'.

       -a, --astream n
	      Extract specified audio stream. Can be used more than once. Default: extract all streams.

       -d, --vstream n
	      Extract specified video stream. Can be used more than once. Default: extract all streams.

       -t, --tstream n
	      Extract specified text stream. Can be used more than once. Default: extract all streams.

       -na, --noaudio
	      Don't extract any audio streams.

       -nv, --novideo
	      Don't extract any video streams.

       -nt, --notext
	      Don't extract any text streams.  Default: extract all streams.

       -r, --raw
	      Extract the raw streams only.  Default: extract to useful formats (AVI, WAV, OGG, SRT...).

       -v, --verbose
	      Increase verbosity.

       -h, --help
	      Show this help.

       -V, --version
	      Show version number.

NOTES

       What works:

       *      Extraction of the following formats is fully supported including writing the stream contents to useful container formats:
		video  -> AVI
		Vorbis -> OGG/Vorbis
		PCM    -> WAV
		text   -> text files (SRT subtitle format)

       *      All other audio streams (MP3, AC3) are just copied 1:1 into output files. MP3 and AC3 files should be usable. Others might not.

       What not works:

       *      Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be).
