fix bad ogms (divx5 prob)

[Apfelstruhdl]

I didn't notice the ogm-divx5 prob. but after reading yesterday about that prob i watched a movie and saw several of the bad frames. ( i think they didn't annoy me so much so i didn't think about them before.) But they are always at the same position and only one frame long.

Then i ran a test and took a bad simpsons episode with a bad frame in it. i demuxed the ogm to a avi containing only the divx. and the bad frame was gone. but then i muxed the avi again into an ogm ( with avi-splitter before the ogg-multiplexer) and the bad frame was again there.

maybe it is not just the method koepi uses but a container related problem ??

if anyone found a way to fix bad ogm, let me plz know as i have several movies on hd that i'd like to fix before i burn them.

thx

Ah, nice to know that those results are random.
No need for me to rewrite that filter chain :) *phew* several hours of unneccessary work saved, I thank you Apfel!

Best regards,

i saw this problem when playing a divx502 with b-frames +ogg audio file with the DivX502 directshow filter. with divx501 dshow filter or without filter no bad frame, and with ffdshow filter no bad frame and good postprocessing :D

ps: use xvid :sly:

But other users wrote that they didn't get any probs when thay muxx manually using graphedit. so maybe the stream get somehow screwed by the way oggmux builds the graph.

i personally also think that a avi-splitter would be better to use.

But now i understand why oggmux is able to transform a already finished avi completly into ogm with sound, by just selecting the video in oggmux.:D

[Apfelstruhdl]

just muxxed an avi/ac3 into ogm with graphedit manually and same prob accured.

maybe tobias knows somethin'

The problem resides in divx directshow filter, not in the mux process.

If you mux the video with oggmux or graphedit is the same thing; the only working solution is use ffdshow por playback, the last version available is suggested.

I can confirm that it is NOT a problem by OggMux... relax Koepi ;) I mentioned that the little proggi CombineAviOgg or even using just Graphedit solved this bad frame problem. But I was (I'm) wrong. Apfelstruhdl, just as you said these bad frames reoccured at the same frame... I was a bit too fast with my solution, sorry guys :(

The longer I'm thinking about the more I'm thinking about container related problem - just as Apfelstruhdl mentioned it in his post. But that would be very, very strange because as long as you listen to your vorbis stream you can't hear any bad results within this stream. "Funny thing" about it is, that not every avi+ogg muxed movie got these bad frames (in my case). Some movies have these bad frames but they are rarely noticeable or in the other case they are very annoying.
Maybe we should wait until MCF is ready and maybe then all our problems are gone... who knows (Christian??!! ;) ) or just stick to OggTarkin one day.

I did it the same way Apfelstrudl did.

I had an oggmuxed file with errors, demultiplexed it, got a perfect avi, muxed (with graphedit, oggmux and combineaviogg) and had the errors again at the same place.

Think we have to make one movie with ogg sound muxing it all the ways we know, after that watching and comparing them (are there errors, are the errors at the same timestamp, are te errors the same...)
But therefor you will have two watch the same movie at least three times, we have to choose a good one ;) Matrix or so

I thought there are only errors if you use oggmux, sorry Koepi:o , cause my graphedit files seemed to be ok, maybe I have to look more into the details.

Could it be that the ogg files get damaged when putting them into the container ?

Or should we go back to mp3 ?:scared:

Edit:
ffdshow really works, my problem movie with ffdshow for divx5 enabled had no errors. (Just to confirm your thoughts)

[sillKotscha]

ffdshow might be the solution - for some reason there is a conflict between the vorbis decoder and the divx decoder. Using ffdshow solved the bad frames for now - but haven't tested it enuff...

here I found out that ffdshow can be the solution...

arf! don't mux avi and ac3 with oggmux!!
first mux avi and ac3 file with nandub and now you can mux the new file with subtitles, chapters, etc.. in ogm container with oggmux. but not mux directly ac3 with oggmux !

[Apfelstruhdl]

i think nobody did....:)

@all::stupid:

I am sorry that I have to post something again, ffdshow was not able to solve my problems in all movies, only the first seen part of my problem movie, another one is horrible now. This was my last post here, i am ashamed cause of posting so much crappy things...:o

I think I have to go now to hide myself under the carpet:scared:

Ogg is the container. Your audio is Vorbis which goes in the container.

Just wondering if anyone tried XviD B Frames inside of an Ogg container yet. I realize B Frames is in early stages, yada yada but just curious what the result was.

I noticed the same broken frames some month ago and it became a long thread. I switched to ffdshow and no bad frames ever appeared again. And as it seems, it only happenes when you use the DivX Playback filter. XVID filters where fine as well.

First I was afraid to get problems using ffdshow, but after trying it for 2 month I'm totally satisfied. It's looking good and it has lots of features, that DivX Filter does not have.

Something very strange, I have cutted a sample of an ogm with "broken frames" inside and the sample has no issue !!

OGM : divx 5.02 (GMC, B-frames and normal psychovisual settings) with one ogg stream.

my experience:
when using ffdshow it is better, but the broken frames (or however you call it) are not gone in every movie
