Solved y41p codec is needed to play old video

May 27, 2012 at 20:44:32
Specs: Windows 7
I recorded some video on my old Dell laptop through the Dell Webcam program. Apparently it recorded it with the Y41P video codec, which is not recognized in any program I've tried to use to play it (including VLC, Quicktime, and Windows Media Player).

I can't find the Y41P codec anywhere online.

1) Anyone know where I can find the codec?
2) Is there any way to convert the video file to another format/codec without first having the Y41P codec?

Thanks!

There seems to be no evidence that a playable file was ever produced. If it didn't play on the laptop originally then it is likely that a dud and unplayable file was produced at the outset.

An avi file is quite commonplace. It is not normally necessary to be play it back with the same codec that produced it.

Always pop back and let us know the outcome - thanks

You can't convert any audio or video file if the converter can't read the file you wish to convert.

I found a link for the The Y41P codec (aka brooktree 411 codec) but it's dead. Sorry.

What file type did it produce?

It's an .avi file. VLC is only able to play audio on it. I found a program awhile back that let me convert it. The newer version has video - kinda. The colors are weird and the screen is split in 3 horizontally, with strange overlaps. Looking up Y41P on fourcc, the strange split makes sense:
"Y41P 0x50313459 12 (bits per pixel) YUV 4:1:1 (Y sample at every pixel, U and V sampled at every fourth pixel horizontally on each line). A macropixel contains 8 pixels in 3 u_int32s."
Oh, also it's upside-down in the converted version :)

I just found and tried LEAD Multimedia Tools. Their support said it included the right codec, but alas, it seems it doesn't either. I was, however, able to convert the original and get what I got on the other conversion, and right side up!

I feel like somebody out there must have that codec.

A possible workaround:

If it still plays on the old laptop you could use Krut Computer Recorder to capture it off screen. If you go this way ensure you set Krut to "stereo" and "16 bit sound" (otherwise sound is poor). Krut produces rather large mov files and can take some time to encode.

Thank you for the response. Unfortunately that won't work for two reasons.
1) I sold the old laptop a couple months ago, and more importantly...
2) It never even worked on the laptop. Strange, I know. It recorded using that antiquated codec, but there was no software included that could even play it. Yeah... I don't get it either.
Any other thoughts?

Okay. Let's assume you're right and the file somehow was a "dud". Is there any way to fix my video - to merge the three images together, so that I have one clear, non-pixelated image? As it is, none of the three images (stacked horizontally) are very clear.

No way that I know. Keep watching in case someone else knows a way, although I suspect it is unlikely.

If you should come back I did have one further thought. It is probably far too hopeful but there are freebie file converters out there. One is called "Super File Converter", this one:
http://www.erightsoft.com/SUPER.html

It is quite on the cards to convert an AVI to a new AVi. Most likely it will still give the same bad results but there's nothing lost by trying it.

It almost sounds like the old TV days when the line speed (line hold) was badly adjusted. I assume other AVI's play OK but I wonder what would happen if you set to a different resolution. Maybe refresh rate has better possibilities but I know you have to take care to ensure you don't go too far and get stuck with an "out of range" error message. If you can get it to display then Krut should be able to capture it.

I guess I'm just thinking aloud really.
