[FFmpeg-user] libfdk_aac: Unable to initialize the encoder

[Abu Abdullah]

Hi,

I'm facing an issue with encoding 1 file:
ffmpeg -i 010.rm -c:a libfdk_aac -profile:a aac_he -b:a 16k -movflags
+faststart -af aresample=async=1000 010.m4a
..........
[libfdk_aac @ 00000246b0b6a980] Unable to initialize the encoder: Invalid
config
Error initializing output stream 0:0 -- Error while opening encoder for
output stream #0:0 - maybe incorrect parameters such as bit_rate, rate,
width or height


the issue is only with input files with 8k b/s rate. it is working fine
with input files with 16k
