View Full Version : Very Strange decoding

I am relatively new to Xvid so bear with me. I recently switched to Xvid from Divx after their horrible 5.0.3 release.

The problem I am having is my encodes playback intermittently. Without any changes in programs or setups, 4 movies encoded with the same parameters play back differently. One plays back fine, 2 playback with flashing "broken b frame" in large letters across the screen, and the last crashes the media player. i thought the files just corrupted, but the movies switch between which ones work and which ones don't.

attempted solutions: reinstal the build of Xvid used to encode the movies. Tried newer and older versions. Tried several versions of ffdshow. Tried BS player, Zoom player, WMP, Power Divx. Changed fourcc to DX50 (resulted in artifacting from Q-pel but no more broken b frame message). Loaded the movies into vdub and scanned for bad frames- none.

The movies all were encoded with q-pel, gmc, bidirectional frames (divx compatible), new modulated HQ, XVID fourcc, default bframe compression with 2 bframes, 2-pass encoding. The only changes from one file to the next was the res to meet a 0.2 bit/pix ratio. I used avisynth to frameserve all of the files as created by gknot 0.27. All 4 movies worked yesterday, and today I have revolving decoding problems.

Any suggestions would be appreciated.

I found a workaround. I tried using Xvid to decode the movies by disabling Xvid in ffdshow but all i got was green screen. I uninstalled ffdshow and all of the movies now work. This is all puzzling to me but at least its working. i would like to be able to use ffdshow as the options are nice.

I had nearly the same problem.

try to use lastest Nic Xvid codec (that has a new direct show filter) or try the lastest Ffdshow Alpha.

They works for me :)

I have the nic decoder installed. Now there is a new problem. I can't make an avs file out of the movie and TMPGenc won't recognize the format to make a SVCD. Maybe I will try vfapi again and see if it will read the xvid file. The newest ffdshow gave me the broken bframe message on all of my xvid movies, not the revolving problem. At least it was consistent LOL.
