Title: MpegPlayer seem not work well under sansa E200 V2
Post by: bashee on June 04, 2010, 02:23:59 PM
Hi all,
i have use rockbox for a long time, and it works fine, both audio and video. However, i update it to latest version - R26546. Then I found when I played an video (which previsouly works fine), now showed a very bad quality. It like the player play it under a very low resolution, but acturally the video has a high resoultion(320x240). Any one can help?

Thanks a lot!

The e200 screen needs 220x176 video.

Thanks for your reply. I understand that. But these videos playing fine with previous rokbox version. But now with new version, it really showed bad quality...that's i don't understand.

Mpegplayer doesn't do any scaling, so you need to adjust the video to have the same resolution as the screen.

I'm having what I think is the same problem on my e200v2. All my videos played fine on my old 25508M build (added in a keyboard patch, so I don't figure it matters). Anyway, I updated to 26561, and all the sudden all of my videos play funny. Specifically, every other line seems to be shifted to the right by one pixel.
I know that it's a big gap between versions, but I'd be willing to try archived daily builds to track this down, if someone's willing to fix it.

Theres been a lot of changes to the LCD code in between those versions (r26362, r26399, r26387...) and a few since.  I would try a newer build and see if it works.  If not, you'd need to compile and test 10 builds using a binary search to figure out which one broke.

Alright, I tested the current build from the site, and it's still broken. I'll be hunting for the revision over the next few days. (Assuming real life doesn't get in the way.)

Edit:
The version's built faster than I expected. Revision r26350 is the culprit for this graphics glitch.
I added a bug report on flyspray: FS#11421

Revision r26350 is the culprit for this graphics glitch.

This has been fixed with r26997
