[help] questions about mpc ogg(ogm?) splitter

[h9903209]

1. some confusion:
ogg splitter decode vorbis audio
ogm splitter decode ogm container
is that true or not?

because I find mpc has built-in ogg splitter, so I try uninstall oggds0995 but then fail to decode ogg audio, but can still play the ogm video...so mpc built-in one should be ogm splitter, right?

2. does mpc built-in ogg(ogm?) splitter has standalone version or not? because it is better than oggds, e.g. can jump 5s backward accurately and quickly. I want to use it + corevorbis to replace oggds0995 so I can use other players, e.g. zoomplayer with this standalone ogm splitter, is that possible?

Hi h9903209,

the matter about splitters and decoders is actually a little complicated, but here we go:

The OggDS filter collection of Tobias Waldvogel (tobias.everwicked.com (http://tobias.everwicked.com)) is a collection of OGM splitter and Ogg Vorbis decoder, bundled in the same package (actually file: OggDS.dll).

The splitter is the part that reads the file from your hard disk (parsing) and splits it (hence the name splitter) into single streams. These streams are then handled by other DirectShow filters. One of them is able to decode Vorbis audio and comes with OggDS filters. The video streams in your OGM are handled by their respective decoder filters like XviD DirectShow filter or ffdshow.

Now the guys at corecodec.org coded their standalone DirectShow filter for Vorbis audio. It's called CoreVorbis (http://corecodec.org/projects/corevorbis). This filter is just a decoder though, it can't split OGM files.

Gabest implemented his own OGM splitter in his Media Player Classic. There is unfortunately no standalone version available, but if you use MPC anyway, you just have to install CoreVorbis to be able to watch OGM files with Vorbis audio.

CoreVorbis is also used in conjunction with OggDS as it has higher merit than the internal Vorbis decoder.

thx for your wonderful reply! It clears all my confusion instantly! ^_^

Wish Gabest make his better ogm splitter a standalone version so we can replace oggds0995. I guess with this splitter plus corevorbis we could convert ogm to rmvb directly too. ^_^
