HowTo: Use FFmpeg's "aresample" audio filter

Here's the link to the official FFmpeg's Filter Documentation for "aresample".
It shows examples, but it doesn't show how to use them in the commandline.

Here's how:

Code: Select all

$ ffmpeg -i input.ts -c:v copy -c:a pcm_s16le -af "aresample=async=1000" output.avi"
Just used this code to fix a problem where the audio ran slightly too fast and ended before the video.
The "async=1000" option to aresample worked automagically. Thanks ffmpeg developers!
