The VideoLAN Forums

Hello! There is something wondering. I have a avi file. It's xvid encoded. When i play it using VLC, the output quality of video is very bad.

I had uploaded the file to a file-share website, url: http://www.mediafire.com/download.php?nub79dtss0kacb2

then i try another player like SMPlayer. At first, the result is the same as VLC, not good.

Immediately, i find that in SMPlayer, it default use the divx decoder (ffodivx - FFmpeg MPEG-4 [mpeg4]) to decode the file.

after is how to find the type of decoder on SMPlayer: right click the mouse on the video playing, select 'option', and then select 'attribute and info', on the video decoder tab , you can find which decoder is using.

When i change the decoder to xvid ( Xvid (MPEG-4) [libxvidcore.a]), the output quality of video can match i expected.

And i try to play on wmp12(on win7) , the result is good too, that is same as SMPlayer using xvid decoder.

is bug of VLC? or the avi file is not correct? can someone help me? thanks!

Yes, confirmed.

But I got the same decoding artifacts issue with MPC-HC, ffdshow, MPlayer and FFplay but not with the standalone Xvid decoder nor with Arcsoft decoder, which means this is a general issue of the FFmpeg decoder and not VLC related only.

thank you for you answer. it means that i can not play xvid correct on vlc? can i change codec to solve this on VLC as same as SMPlayer?
