Some xvid files play back jerkily

Hi, I've uploaded a sample file called 'Xvid_jerky_1.avi' which exhibts jerky/stuttery playback with newer versions of Libav. This problem seems to start with Libav commit '759001c534287a96dc96d1e274665feb7059145d', commit title is "lavc decoders: work with refcounted frames". If I build vlc with the commit previous to that (commit no '6e7b50b4270116ded8b874d76cb7c5b1a0341827', commit title "mpegvideo_enc: drop support for reusing the input motion vectors" ) then playback is smooth. Playing this sample with older versions of vlc also results in smooth playback. Hope this info helps.

Just logged on to say that this problem has been resolved with commit e8c82fb8a9ea01dbc6b1dd98b527d2afce98e82d (avcodec: do not use deprecated reordered_opaque) on Sun, 28 Apr 2013. I've rebuilt vlc and tested with aforementioned files which now play properly. A big thanks to 'Team Vlc' for resolving this! Regards.
