Automatically concatenates MP4 files using the ffmpeg and mp4box utility and generates chapters for each concatenation point. Compatible with Xbox and Playstation video players.
When combining several files with no audio (only video stream) this error occur:
Stream specifier ':a' in filtergraph description [0:v]scale=1024:576:force_original_aspect_ratio=1[v0];[1:v]scale=1024:576:force_original_aspect_ratio=1[v1];[v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a] matches no streams.
Not sure what this means but windows tells me I am missing "js.dll" no idea what it is and i'm not gonna over think it just gonna find another project. I just want to leave a comment in case others stumble onto the issue.
