Bug 299994

Summary:	media-libs/jpeg-7 about five times slower than jpeg-6b (at least for media-tv/xbmc)

Description Urs Zurbuchen 2010-01-07 06:49:22 UTC

Yes, of course, performance issues are to be resolved upstream.

But: Wouldn't it be possible to reinstate the ebuilds for jpeg-6b? To allow users to decide for themselves whether they want a bleeding-edge system or a fast one.

Again, yes I know, old ebuilds can be retrieved from CVS but this is kind of cumbersome and not very user friendly.

Kind regards,
Urs

Reproducible: Always

Steps to Reproduce:
1. Take current, stable Gentoo system
2. Make sure it has jpeg-7
3. Install and run media-tv/xbmc

Actual Results:  
Image transitions, especially for background images and fanart, take several seconds.

Expected Results:  
Image transitions should be near instantaneous.

After downgrading to jpeg-6b-r8 image transitions were noticeably faster.

Everything in tree should work by now with jpeg-7 except some minor issues 
with mjpegtools and jpeg2yuv (soon to be resolved). 

The ebuild won't be restored for upstream performance problems.
