Important: An important v.codec is missing!
« on: February 28, 2013, 04:25:23 PM »
Hello Mean!

An important video codec is missing in the Avidemux codec palette. It is the best lossless codec: the famous FFV1.
I can't understand how did you forgot that highly important codec.
I think it would be very easy to implement the codec in Avidemux.


Thank you for Your reply!
Peter.

Hello!

I think about the FFV1 encoder. I use the standard 2.6 x64 version of Avidemux, and the newest x64 nightly builds.

Would that not be the 1st option in avidemux 2.6.1, video output (FF)HuffYUV? Then using Configure to switch between HuffYUV and (FF)HuffYUV?
If that is not the case checkout avidemux 2.5.6

Don't understand your reply?

On April 16, 2006, a commit-message by Michael Niedermayer confirmed that the bitstream of FFv1 (version 1) is fixed:

Hello Gruuthuse!

I'm affraid , You confused FFv1 codec and Huffyuv codec.

There are huge differences!

I registered for this - the codec FFV1 really NOT exist in palette. And it was in 2.5.6.
And ffHuffyuv is NOT FFV1 codec.
And return it please.

it's really missing.
