[xine-devel] MPEG-4/DivX and OggVorbis

[Ivan T. <dr...@sy...>]

First I want to apologize if I bother someone with updates that are
already aplied in CVS or newer release.
I only checked the 0.9.8 release of XINE-LIB.

----------------------------------------

Subject 1 : Buffer Types

Divx5 uses a new FOURCC : 'DX50' instead of the usual 'DIVX'.

Also, there's an Ogg Vorbis ACM that helps people insert Vorbis audio
in a AVI File (also used by the NanDUB variant of VirtualDUB).
(Too bad they didn't make a new release using Vorbis RC3...)

That's why I did the following patches to
src/xine-engine/buffer_types.c :
diff buffer_types.c.orig buffer_types.c
73a74
>     mmioFOURCC('D', 'X', '5', '0'), /* Patch : DivX 5.0 / Xvid
streams */
381c382
<     0
---
>     0x674f, 0x676f, 0x6750, 0x6770, 0x6751, 0x6771, 0 /* Patch :
Ogg audio in AVI files */

So now my Xine can play (almost) all DivX5 and Vorbis content


----------------------------------------

Subject 2 : GPL MPEG-4 engine

Xvid is an attempt to fork from OpenDivx and create a GPL-ed MPEG4
engine, compatible with DivX.

Currently it can decode all Divx4 content and some Divx5 content.
It doesn't work yet on Divx 3.11 content.

Although it's primary targeted for WIN32 platform, its CORE part
builds perfectly under Linux too (there's a Makefile provided for
that purpose in the package)

I tought it may be interesting to mention it in the REAMDE.divx4 file
of XINE-UI package.

I hope this will be useful.
