here a few overhead comparisons on a MKA file made with Jory's FLAC
encoder filter and matroskamuxer filter on Graphedit :
Source file : 682 MB
FLAC ( level 5 ) : 409 MB
OggFLAC ( level 5 ) : 413 MB
MKA Flac ( level ? ) : 438 MB
Any explanations why overhead is so much worse than for OggFLAC ? Do we
use lacing in matroskamuxer on DirectShow ? Any news from Gabest about
using the new lacing sheme in an updated version of matroska muxer filter ?
I still wonder if its a wise thing to treat FLAC as a normal ACM codec
in conjunction with A_MS/ACM .
@jcsston, gabest : any chances of uniting efforts to define a new
MEDIASUBTYPE for connecting FLAC encoder filter to matroskamuxer, so
that a native codec ID was used and an efficient lacing sheme ?
