 I'm trying to run an audio encoder using ffmpeg command but when I try to
 encode in aac_ld codec or aac_eld codec, it gives me an error stating
 that...

 {{{
 [libfdk_aac @ 0x1e20770] Unable to initialize the encoder: Transport
 library initialization error
 }}}

 but for other codecs it's running perfectly fine.

 I'm using this command for aac_eld codec


 {{{
 ffmpeg -y -f alsa -ac 2 -ar 44100 -i hw:0 -acodec libfdk_aac -profile:a
 aac_eld -b:a 320k -r:a 48000 -f mpegts
 udp://192.168.1.60:1234?pkt_size=1316
 }}}

 and getting this output

 but for another codec like aac_low it is working perfectly fine.

 Is there any other program using which aac_ld can be encoded
