[SOLVED] Simple batch script for merging video and audio with ffmpeg using two wildcards

Simple batch script for merging video and audio with ffmpeg using two wildcards

as the title says, im trying to mass-merge videos and audios with the same name together in ffmpeg

I tried

for %%A in (*.adx) do ( for %%B in (*.m2v) do ( ffmpeg -i %%A -i %%B %%B.mp4 ) )

but while it does change the video it works on, the audio remains the same. For example, if i have A, B and C in .adx, and A, B and C in .m2v, the result will be that all 3 videos (A, B and C) use the audio A.

Solution

…for %%B in (%%~nA.m2v)…

Your code executes ffmpeg for each %%A for each %%B, so the result is the either the last %%B (if ffmpeg auto-overwrites the destination file) or the first %%B (if ffmpeg skips if the destination file exists).

The modification will execute ffmpeg only if the name part of the second file matches the name part of the first.

A simpler way would be

for %%A in (*.adx) do ( ffmpeg -i %%A -i %%~nA.m2v %%~nA.mp4 )
