There are a lot of video codecs out there, and some of them are far, far more efficient than H.264. But, as efficient as HEVC or WebM might be, they're frustrating to stumble across if your playback device is a Raspberry pi which has neither the hardware support, nor the processing capabilities required to deal with those codecs without stuttering
It is, however, incredibly simple to convert to X264 with ffmpeg, the below snippet creates a utility script to do so by just passing in the input filename and the destination file to create
#!/bin/bash # # Swap something to X264 with AAC audio IN=$1 OUT=$2 if [ "$1" == "" ] || [ "$2" == "" ] then echo "$0 [in file] [out file]" exit 1 fi ffmpeg -i "$IN" -c:v libx264 -codec:a aac -strict -2 "$OUT"
