FFMPEG extracts only half of the audio length

[Sviests]

Good day,everyone.

I'm trying to extract an audio from a HLS stream with FFMPEG, although the console shows that it extracted it full length, the extracted audio is only half long of that.

FFMPEG input:

ffmpeg -i http://192.168.1.104/root/media/hdd/recordings/recording_09_09_2018_14_33_My_Recording.ts.m3u8 -vn -acodec copy outputaudio.aac

After file is extracted this is what appears on commandline:

size=  391131kB time=04:38:00.12 bitrate= 192.1kbits/s speed=5.28x
video:0kB audio:391131kB subtitle:0kB other streams:0kB global headers:0kB muxin
g overhead: 0.000000%

The file is exact size as mentioned,however the duration is only 2h 20min,which means that there are the 2h 18min missing here.

I tried playing the stream in VLC to double check and can confirm that actual duration is 4h 38min.

For some weird reason when i try extracting video with audio,FFMPEG messes up the whole audio and dramatically lowers it's quality (even tho i have added the -acodec copy option with it),but it extracts it full length. That's why i need to extract the audio separately.

Could this be related to FFMPEG having some issues with AAC codec?

Any tips appreciated.

Edit: I discovered that for some reason FFMPEG changes framerate from 25 (that's in original stream) to 48.something. I don't know why.
