[FFmpeg-user] preset files

[Scott Johnson]

Hi Francois,

I'm using a third party compiled API, to talk to FFmpeg. I can't change the command line structure. I would have to purchase the API source to do it.

If that is true. They should remove the pages from the website, talking about the feature.

But I can see using these files for several of my projects. It's too bad they removed this feature.

Thanks,

Scott.

As far as I know the use of preset files has been deprecated.

I'd use a wrapper that takes the source and transport type arguments from your API and then specifies the additional settings on the actual ffmpeg command line.
