Description
Summary of the bug:
aac format profile is always LTP in 3.2.x by filter aac_adtstoasc
LTP was not compatible for iphone or ipad
So, I want Format profile to be LC
Is there any setting for it?
How to reproduce:
% ffmpeg -y -i input.ts -metadata creation_time="$( date --utc +'%F%T')" -vcodec h264_qsv -b:v 2800k -s 1280\x720 -acodec copy -bsf:a aac_adtstoasc -bufsize 20000k -maxrate 25 000k -movflags faststart -f mp4 -look_ahead 0 output.ts .mp4.rec Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LTP Codec ID : 40 Duration : 29 min 19 s Duration_FirstFrame : -21 ms Bit rate mode : Constant Bit rate : 252 kb/s Channel(s) : 2 channels Channel(s)_Original : 1 channel Channel positions : Front: C Sampling rate : 11.025 kHz Frame rate : 10.767 FPS (1024 spf) Compression mode : Lossy Stream size : 52.9 MiB (9%) Default : Yes Alternate group : 1

No problem in version 3.1.x
Profile is LC in mp4 though same source
So, I think LTP is default setting in 3.2.x

To make this a valid ticket, please provide the (simplified) command line you tested together with the complete, uncut console output and an input sample that allows to reproduce.

Please reopen this ticket if you can add the missing information.
Maybe your input file is also LTP profile? The BSF cannot change the profile of the stream.
If you posted a full log, we would know.
