What filter would i use to concatenate multiple videos files (no horizontal stacking)?
Basically, trying to replicate something like this
"ffmpeg -i opening.mkv -i episode.mkv
-filter_complex "[0:v] [1:v]
concat=n=2v=1:a=0[v]"
-map "[v]" output.mkv"

I'm trying to convert from a mkv file (with audio) to a .webm file. I'm trying to replicate this argument
"ffmpeg -i CombinedOutput.mkv -vcodec libvpx -acodec copy output.webm".
I can take in the .mkv file as a video input but the video output also requires an audio map argument. Is there another way to go about this that i'm not seeing?

Would like to request an XFadeFilter implementation

We had a question.

We are planning to deploy a service that will run ffmpeg for video processing in an Alpine Linux Docker container. We don't want to have the FFmpeg.exe binary in the project itself. Rather, the DockerFile will run and install ffmpeg in that Alpine Linux Docker Container. Do we need to set the path to the ffmpeg.exe binary manually in Linux?

We have also set FFMpeg as a PATH variable in Windows 10 so that when we launch the command line console and enter "FFmpeg", it is able to tell us information about the ffmpeg binary. However, when we run the project locally in Windows 10, await ffmpeg.Render().ExecuteAsync(); call fails and says file not found. Do we have to set the path to ffmpeg.exe binary manually here as well?

Hi there,

Had a question. Is there a filter for using the Concat Protocol rather than the Concat Demuxer (which is what I think the current ConcatFilter class does)?

Looking at Concat Protocol here: https://trac.ffmpeg.org/wiki/Concatenate
