Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
| #!/bin/bash | |
| set -eo pipefail | |
| container=$1 | |
| image=$(docker inspect --format '{{.Config.Image}}' $container) | |
| cmd=$(docker inspect --format '{{.Config.Cmd}}' $container) | |
| if [[ $cmd == '<nil>' ]]; then cmd=''; fi | |
| binds=$(docker inspect --format '{{.HostConfig.Binds}}' $container | sed "s/\[//; s/\]//") | |
| if [[ $binds == '<nil>' ]]; then binds=''; fi | |
| envs=$(docker inspect --format '{{.Config.Env}}' $container | sed "s/\[//; s/\]//") |
Hello, brethren :-)
As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".
