[aac_latm @ 0x25abe00] Non-byte-aligned audio-specific config 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_latm @ 0x25abe00] If you want to help, upload a sample of this file
