ogg vorbis and rehuff

[ysilog]

in first, excuse me for my poor english...

well the rehuff encoding improve sound quality in ogg and make ogg smaller (3%)

well, rehuff in ogg vorbis have problem with seeking, but i've solution !
and this solution resolve also TCMP's problem with ogg (sound distorsion)

for your ogg rehuff function correctly with seeking it's necessary to encapsulate it in mka file, and after, no seeking problem !

this solution is simple but not universal due to not all player can play mka

for movie if you mux ogg "rehuffed" with video i think of there is no seeking problem, but i've not tested this...

ogg contener is not perfect :( improve it is necessary i think...

The problem is not the ogg encoder, I read that there is a problem with libogg.
There is a other solution with muxing to mka: remux file in graphedit using Tobias OggDS:

rehuffed.ogg -> Ogg Splitter -> Ogg Mux -> File Writer

After that rehuffed file is perfectly seekable (the file is not bigger, my test showed that the size differs by about 20 bytes)

[ysilog]

uh uh !
before your tips
seeking function very bad (in winamp 2.91 with in_vorbis.dll 1.32)
seeking function very bad and sound distorsion (in TCMP 4RC3 with OggDS 0.9.9.5)
seeking function very bad (in windows media player 9 with OggDS 0.9.9.5)

after your tips:
seeking not function (in winamp)
seeking function perfectly and less sound distorsion (in TCMP)
seeking function perfectly (in windows media player)

these solutions does'nt satisfy

does someone know him if he/it is foreseen to correct this problem of the libogg in the future ?
the obligation to use the contener mka is bothersome... of the least at present

I yust tested that again, I could not reproduce your error. The rehuffed/remuxed file was perfectly playable in winamp 2.81 / Nullsoft Vorbis Decoder v1.2.9
The file had a very high bitrate (q10), here are the filesize results:

original: 7.874.948 bytes
rehuffed: 6.102.936 bytes
rehuffed/remuxed: 6.102.963 bytes

22,5% compression, not just 3%!! The output is bit-identical. It seems that at high bitrates rehuff can save a lot of space.

I read somewhere that xiph is coding libogg2, which will work correctly.

my error come probably with Nullsoft Vorbis Decoder v1.3.2, where i could find v1.2.9 ?

i've not compare files... but i said 3% because DSPguru said this...
but gain of quality is real and very interesting

Cool :)
does have you there him one date of announced?
