Re: DeckLink output --enable-decklink

Unfortunately Decklink cannot be included due to licensing issues. You'll have to build FFmpeg yourself, and there are many scripts available to assist with this.

Re: expected and actual bitrate

It should just be

Code: Select all

-b:v 100k
to target a bitrate. See https://trac.ffmpeg.org/wiki/Encode/MPEG-4

If that still doesn't work, include a ffprobe of the output.

Re: play video file by ffmpeg in a windows form applicaion of C#

That's way too generic to get any help. You need to be far more specific about what you need help with.

Re: building mingw toolchain with pthreads, gendef, widl

This looks like MSYS which hasn't been tested and isn't supported.
