 ***
 [aac @ 000002142aaef380] Gain control is not implemented. Update your
 FFmpeg version to the newest one from Git. If the problem still occurs, it
 means that your file has a feature which has not been implemented.
 ***
 [aac @ 000002f5d27ff380] Sample rate index in program config element does
 not match the sample rate index configured by the container.
