What codec for webm?
On a new Server 2019 and trying to use .avs input to ffmpeg and getting similar, but different, errors on DirectShowSource and FFVideoSource.
sld2=DirectShowSource("8_0_0_2.webm", fps=15, convertfps=True)
Gives the error: The format is not supported and
v=FFVideoSource("8_0_0_2.webm")
Gives the error: Video codec not found. If I switch the sequence so I call FFAudioSource first, I get the error: Access Violation.
I have installed the K-Lite Basic codec pack but I thought that's all I had installed previously. The MediaInfo for the file is:
