  1. to be more precise I'm looking for information about:
    • Where do I find the documentation for the arguments accepted by ffmpeg for ffvhuff?
      Through Google I found that:
      • ffvhuff can be used through "-vcodec ffvhuff"
        and has at least these options:
        • "-context X" <- What are vaild values for X ?
        • "-coder X" <- What are vaild values for X ?
    • Where do I find the documentation for the arguments accepted by ffmpeg for utvideo?
      Through Google I only found that:
      • 'ut video' can be used through "-vcodec libutvideo"
        Couldn't find any information about what options are available for it.

    Something like the Cheat sheet for FFV1 would be really nice.
    Also if no such documentation exits, it would be nice if some who has some experience with either of those encoders can shed some light on the matter.

    Thanks!

    Cu Selur

    If my dos memory still works don't you just do -? or something like that to pull up all the options in the dos prompt?

    or maybe just ? after the command?

    edit - just tested it it is /? after the exe command. Hope that helps you a little.

    Glad to help and it is actually /? after the exe. Here is what I got with the version of ffmpeg I have (don't know what version that is):

    edit - sorry selur I don't have that huff or utvideo extensions you mentioned. I'm not sure if this is exactly what you were looking for either. Hope its something at least.

    Code:
    ffmpeg -h full>path-to\ffmpeg-help.txt
    Not sure if the answer Selur looks for is there though

    Awww, I tried to post the output of ffmpeg -? full but got a server error. But believe me, it's good.

    /? just gives you an error, and it lists the kind of options you SHOULD be giving it instead.

    No specifics on UT though

  8. No, sorry folks. I know the full help, but it's not really useful since it doesn't specify which options are supported by which codec and testing them all is simply to much work.

  9. UTVideo

    There are no special options for utvideo, just need to set -pix_fmt correctly.

  10. Okay, strange thing is:
    'ffmpeg --help encoder=ffvhuff' returns:
    Code:
    Encoder ffvhuff [Huffyuv FFmpeg variant]:
        Threading capabilities: frame

    but '-coder' and '-context' do configure ffvhuff
    -> I'm skeptical in trusting the help command line output.

    Those options should be the same as FFV1

    -coder 0 = VLC, -coder 1 = AC


    Code:
    Coder: 	-coder 	0, 1 	0=Golomb Rice, 1=Range Coder
    Context: 	-context 	0, 1 	0=small, 1=large

    These would be all the possible settings for UT:

    Are you interested in Predict Median/Left?

  14. Ah, that's what the vfw interface looks like.

    Are you interested in Predict Median/Left?
    Sure. Also the "Frame divide count" if it is available or is it indirectly handled by ffmpegs normal '-thread'?
