As i'm a lazy ass  i will simply cut and paste what i said here :
Its good to see that Xiph people will now officially open up the scope of codecs to be put into Ogg. Although never confirmed officially by Xiph team, rumour had it that Ogg Theora should stay restricted to patent free codecs being part of the Xiph family, such as FLAC and Speex, and of course the Xiph codecs itself, means Vorbis and Theora, later Tarkin.
I guess the users of this board here can confirm that these restrictions, if enforced, would have been a big obstacle for the wide spread use of Ogg Theora as a frame work, as video encoders definitely want to have the choice of which codec to use, like AC3/AAC for audio and MPEG4 ( DivX/XViD )/ RV9 etc. for Video.
Now with Tobias work, or at least parts of it, finding its way into official Ogg Theora specs we can at least expect support for all VfW video and ACM audio codecs, even MP3 and AC3. I heard there are other plans also, with respect to a plugin system similar to UCI, so that other codecs could be added also.
With respect to matroska :
We will continue to work on it. Emmett was asking me lately on IRC what the point is in continue developing it, and as i am not a technician but only a organizing guy i know i have failed to give him a satifactory answer. I simply believe in the expertise of the matroska project technicians, who told me many times that Ogg is a very good container for audio and streaming, but it will be pain in the ass to guarantee it can satisfy all needs of the video encoding community without breaking compatibility with existing Ogg parsers.
This project was started about 2 years ago ( as MCF this time ), when it was completely unclear how the future of Ogg might be looking with respect to video, and we also didnt have the feeling that the Xiph people were very much interested in the needs of the mostly Windows based video encoding community. Things have changed a lot since then, but please understand we will not abandon the work we have invested now, but finish the project ( robux4 is in vacation on Reunion Island now, visiting BlackSun and checking out Reunion Ladies .. so dont expect anything before February ), release tools and example files, and leave the decision what container to use to the users. Maybe when John 'spyder' Cannon has finished his work on mf's hybrid Bob AVS filter we can expect the JMF implementation 'Javatroska' a bit earlier !!
| QUOTE | | tangent said on Doom9 : So now OGM = Ogg ?? Not exactly. From what I've gathered, most of the great work which goes into OGM will make it into Ogg but will be spec'ed according to Monty's earlier plan. There will be a converter available to convert current OGMs to the new Ogg. My main worry would be that the present ogm filters are called OggDS, which may cause confusion in the future.. |
