[FFmpeg-user] Issue while merge large .wav file into .webm file

[AMIT KUMAR]

Hi,
Dear Team,
I am using ffmpeg to merge Audio and video making Mp4 file.
While we merge small size of file it creates perfect Mp4 file but, while we
use large file to create mp4 it not works.
whereas  file extension we used .wav and .webm merge both create .mp4.
So, can you help me in this.

Thanks & Regards
