View Full Version : Has anyone come up with an XVid antifreeze yet?

Hi,

Just wondering if anyone has come up with an Xvid antifreeze yet. It would make XVid so much easier to use if it didn't freeze on a bad frame every single time. Many of the bad frames are not even noticeable, but they still have to be deleted out up to the next key frame in order to make the playback smooth. DivX has not had this problem for a long time owing to the integration of DivX Antifreeze directly into the codec.

Thanks,
Rooster.

Worse comes to worse, change the FourCC of the file to DivX and use that to play it.

Please don't create multiple threads about playback problems. FFDShow complaints/requests should be kept to the ffdshow thread.

Also, it sounds very much, from your threads, that instead of creating these files, your simply downloading them.

Support for pirated files will not be given here.

My DVD collection numbers 153 and grows every week. I only download AVIs from Kazaa that I have previously purchased, I am very anal about it. On the few occasions where I have downloaded movies that I didn't yet have on DVD, I have purchased them after the fact. It is much easier to simply DL them than to make them myself, you just select the film and Kazaa does the rest. I have made about 20 backups of DVDs that I haven't found on Kazaa, and each took a couple of days to make, some a week or more if the result was not satisfactory.

I do this because in the past when I have gone over to a friend's house to watch DVDs, I have on occasion left the movie party with one less DVD than I started with (I have seen all of my DVDs more than once, so I usually arrive with a handfull and let other people pick). I almost always get it back in a day or two, but some have disappeared forever. The simple answer is to only show up with DivX movies created from my own DVDs, or movies downloaded from Kazaa which I own on DVD. If I leave the movie night with one fewer DivX than I started with, I am only out the cost of a single blank CD.

Cheers,
Rooster.

Thats good to know :)

XviD does seem to fail decoding when decoding bad streams in DirectShow, unfortunatly I dont have any of these bad streams to try and circumvent the problem :(

Changing the FourCC might help you for now though,

still no solve of this problem? is it that hard to code xvid not to create bad frames?

What are these bad frames you talk about? I've yet to see any.

Throw a few random bytes into the bitstream as some of these file sharing networks can do (especially if some 3rd party is intentionally trying to corrupt files) and you may get frozen decoding.

Grab BIEW from http://biew.sf.net/, make a copy of an XviD movie and just change a few bytes in the copy, as Blight said.

That should do the trick... :)

holy cow i really thought freezing were extinct with divx3 . i have never seen a freezing Xvid (and i saw tons of xvid) - i must be lucky to use "the right" file sharing networks :)

I to have to agree, i have never seen a freeze frame in 300 encodings with xvid???????

Kazza what is this some ftp or news group we no nothing about. I wouldn't touch their virused stuff and have to say thumbs up to Nic.

While I'm no fan of file sharing either, I don't think the decoder should barf when it gets fed some b0rked input - a scratched CD can do that to you just as well...

np: Sixtoo - Outremont Mainline Runs Across The Sunset (Antagonist Survival Kit)

There's no danger of corrupting your self-produced XviD-files because of a scratched CD. As long as it isn't an XCD with an AVI-format file on it. The filesystem used on normal CDs (or on your PC, to mention it) saves a lot of redundant information for error retrieval.

Nothing to do with XviD. But a damaged file shared over a network is a damaged file. Full stop.

I guess we should close this thread. There really is nothing like freeze frames produced by XviD. What do you think, Nic, Koepi?

Edit: AFAIK there's indeed some error-resilience in XviD. But serious error-correction capability is definitely not the task of a codec. It's the task of a filesystem. If you don't have the file (be it a video, a text or whatever) stored on a disk but receive it over a network, file-integrity is the task of the protocol that the application used for transmitting the file uses. If it fails there still is the chance to safe some of a video IF it has been stored in a container that provides it's own error-correction or at least recognition. Such formats are .MPEG, .OGM and perhaps .MKV someday.
