What happened to AAC padding when converted to FLAC?

Okay so I know that by nature any audio codec that invovles transform will have audio delay. AAC encoder adds padding as it encode the audio.

What happens when I convert AAC to FLAC, which introduce no delay by nature.

That depends on whether the decoder discards the delay samples, offsets the timestamps accordingly, or does nothing. IIRC, it's the third option, which is not ideal, but to be sure you'd have to ask libavcodec developers.

Thanks. I have a better understanding now.
