FFMPEG & LIBAV Encode Error

I keep getting an error no matter if I’m using libav or ffmpeg. I am using a Windows host and when I try the test scripts they output files no issue. I have also added both libav and ffmpeg to my path.

Error I see from encoder queue:

ffmpeg test:

I will say that libav seems to work faster and lighter on my system so I’d prefer to use that option if able. Just not sure why I keep getting the error upon encoding from the queue. If I could pull the queue command I’d love to see it and test that to see if there is some formatting issue.

I have the plugins installed to: C:\ffmpeg\bin and c:\libav\usr\bin
I have each configured as: /ffmpeg/bin and /libav/usr/bin

Thanks for the detailed info. Once we get this working it shouldn’t matter if you use FFMPEG or LIBAV. The plugin should work with either one the same. I don’t have a Windows system to test this on so I rely on users to point out when there’s a problem and looking at the FFMPEG/LIBAV test function now it seems like I’m not testing the full Windows command. When encoding videos, in order to avoid locking up PHP waiting for execution to finish, FFMPEG is loaded using start /B and I suspect I’m not enclosing something in quotes correctly because Windows is interpreting the /ffmpeg which comes right after start /B as a flag rather than a command. Does it work if you change the plugin setting to C:/libav/usr/bin instead of a forward slash? You could also experiment with a regular Windows path C:\libav\usr\bin

After switching to C:/ rather then / it seems to have fixed the issue at this time. Overlooked that as an option during configuration. Thanks.

Great! And I’ll try to find a way of escaping the command in Windows if the path starts with a forward slash.
