Xvid Codec

Introduction

Motion already has a encoder ( ffmpeg ) to create videos ( mpeg1 , mpeg4 , msmpeg4 ). Xvid is a GPL encoder alternative with similar technology as MPEG4 but with a free GPL codec for decoding as well.

Description of Patch

The patch add support to motion to use xvid codec to get mpeg4 files instead of ffmpeg.

Discussion and Comments

xvid will need to add some config parameters as ffmpeg , moreover i think that some current options should change the name to more general purpose , i propose :

• ffmpeg_cap_new -> video_cap_new
• ffmpeg_cap_motion -> video_cap_motion
• ffmpeg_video_codec -> video_codec
• ffmpeg_filename -> video_filename

I agree that the names must change but why not make the name changes consistant with the other changes we made recently. We agreed to use the "movie" in the new on_xxxx options so maybe we should use this in the new names. I also want to avoid abbreviations like "cap". Finally I always disliked the ffmpeg_cap_new name.

So maybe (be welcome to give counter proposals)

• ffmpeg_cap_new -> movie_capture_normal
• ffmpeg_cap_motion -> movie_capture_motion
• ffmpeg_video_codec -> movie_video_codec
• ffmpeg_filename -> movie_filename

I think avilib shold no be part of motion, instead check for it with autoconf (configure.in)
