ffmpeg for DOS ! (Developers)

Has anyone compiled a more recent ffmpeg.exe for DOS
that supports the VP9 codec in most newer WEBM videos ?

The most recent DOS build of ffmpeg that I can find does not have a VP9 decoder.

Therefore, this is the failed attempt to convert a VP9 WEBM into MP4

Also, the most recent mplayer.exe I have is the one from Khusraw in 2012
which also does not have a VP9 decoder.

If we had a more recent ffmpeg with VP9 decoder, at-least we could convert
those VP9 WEBM videos to a format that Khusraw's mplayer.exe could play.

Does this version of MPLAYER on RayeR's page not support VP9 decoding?

http://rayer.g6.cz/download/mplayer.exe

Also, it seems that FFMPEG 2.2.3.0 is latest FFMPEG that he has compiled for DOS.

I remember that Khusraw release a more recent DOS compile of Mplayer around 2017 or 2018 which supported PCI sound cards. I believe this is in the above link, which is the latest DOS compile that I know of.

Thank you... I had not known about that newer build till now.

Well, that one does indeed suport VP9

However... it has the same problem as does the old version I had compiled by Khusraw.

That being... even tho -x 800 -y 600 was used on the command line...
it insisted upon setting a video mode of 1920x1440 which it detected
that my video card could handle.

BUT.. my monitor can't handle 1920x1440 therefore all I got was "Input not Supported"

Is there some command line option or config setting
that I'm not aware of which will 'force' it to use
the specified x/y video mode ?

I tried the DOS build made by Mik back in 2010 on that WEBM which I had converted to MP4

Same problem... it also sets the video mode to 1920x1440 resulting in "Input not Supported"
