Packed bitstream in XviD workaround for MT1389 players
At present players like the Elta 8883 will not playback XviD with packed bitstream correctly. If you have already got encodes in this format and do not wish to re-encode here is what you need to do in order to strip the packed bitstream out LOSSLESSY.
Tools you will need 3divx from http://www.3ivx.com VirtualDubMod from http://virtualdubmod.sourceforge.net Graphedit (Google it not hard to find) Install 3ivx etc First you need to demux the audio in VirtualDubMod. Open the AVI file in VirtualDubMod. Select menu 'Streams', 'Stream list' select audio file and click on 'demux' give it a name and remember where you saved it. After that is demuxed close VirtualDubMod. Open Graphedit. Drag the avi file onto Graphedit. It opens a graph. Delete all the boxes except the first two boxes (One says open file in one box and AVI Splitter in the other). Go to menu 'filters' and add filter from 3ivx '3ivx muxer' and from DirectShow section 'filewriter' and give it name video.mp4 (Must give extension or it will bork). right click on top out pin of AVI Splitter box and click render pin. It should connect itself to the 3ivx muxer and then to the file writer box. Right click on the 3ivx filter and select properties. Tick the Click on play button. Exit Graphedit when file completes. Now click on 'File' 'New' in Graphedit. Drag the newly created MP4 file into Graphedit. Delete stuff after 3ivx splitter. Go to filters again and add AVI Mux and Filewriter under the DirectShow tree list. Right click on '3ivx Splitter' properties. Tick 'Allow Unsupported Decoders' and apply/OK it. Rick click on '3ivx Splitter and select 'Render pins'. Now click on play in Graphedit. This will render the file back to an AVI file ready for the final step. Open VirtualDubMod again and open the newest AVI file. Go to stream list menu and select 'Add' and add back the audio file you demuxed earlier. If AC3 don't forget to right click the newly added audio file, select 'Interleave' and set audio interleave to 64 or 96 milliseconds (Preload can be left as is). OK it and then make sure on the 'Video' menu it is set to 'Direct Stream Copy'. Go to 'File', 'Save as' and save to a new filename. This is your finished movie file with packed bitstream removed. Done. Word of warning. Check the audio is in sync. If not you may need to remux again in VirtualDubMod adjusting the audio delay slightly (That's another topic though). Also make sure 'Direct Stream Copy' is set under VirtualDubMod's 'Video' menu or it will try to re-encode the video (You don't want to do that). Longwinded but works. Waiting for a tool that removes packed bitstream for you in one easy step. EDIT: Updated. No need for MP4UI (And I heard it can cause probs). EDIT: Corrected filter to use on muxing MP4 back to AVI. Thanks for the heads up. Last edited by oddball; 20th March 2004 at 12:21. |

Does anybody know, how I can tell, if packed bitstream was turned on during the encode? Is there any app that shows this kind of information?
I simply can't remember, on which movies I had this enabled, since starting of with Xvid 1.0. cheers, monty |

You can also download GraphEdit from the 3ivx windows download page

guys
it also depends on whether you used 1 or more than 1 consecutive b-frames with packed bitstream

Hoing back to the QPEL issue. I had a file with packed bitstream AND QPEL. I did the usual to get rid of the packed bitstream but now that file will not play video in the Elta. It just plays the audio and remains stuck on the file selection screen. If the file is played on the computer it plays fine (But if you seek you have to wait until it catches up to the next keyframe).
Does QPEL have various settings? |
