ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Tue Jun 8 18:26:52 2021 +0200| [0f168344f1034c84fe85c4a8c3b5638bd4ba9931] | committer: Andreas Rheinhardt
avcodec/adpcm: Disable dead code
This change ensures that the linker can drop adpcm_data.o if no decoder
that actually uses anything from there is enabled.
