[FFmpeg-user] ffmpeg AAC with no global headers is currently not supported.

[Mohammed Sha]

Hi ALL,

While streaming test aac audio using ffmpeg, Not able to get audio at the
client side, while checking this may be because " AAC with no global
headers is currently not supported." as per the link given below.

https://ffmpeg.org/pipermail/ffmpeg-devel/2008-March/050846.html

Tried with the fix as explained in the link then also same issue.

 ./ffmpeg -re -i ~/Downloads/test_audio.aac -acodec copy -vn -ac 2 -ar
44100 -flags +global_header -f rtsp rtsp://
