I’ve just gotten back into ffmpeg fun after a long haitus, during which ffmpeg v5 has come out.
(No deb instructions this time since I’ve passed on to arch, which has a perfectly functional package).
A couple of thing seem to have changed though, namely:
- Bitrates are now in bytes/seconde rather than kbytes/seconde (unless otherwise stated)
- AAC is no longer an encoder module (use libfaac)
- mp4/amr containers don’t seem to work to well with libfaac, use 3gp instead to be safe.
Which gives:
ffmpeg -i input.avi -vcodec h263 -b 409600 -s 352×288 -acodec libfaac -ab 65536 -ar 48000 -ac 2 -f 3gp output.3gp
Happy encoding
