Hi, we have video stored in S3.
When we probe the data using ffprobe, we see similar:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'https://s3.amazonaws.com/bucketname/video_name.MP4':

which shows both audio and video data is present.
However, when we stream it through VODS3 application, we are unable to play audio on VLC. When we probe the same stream, but coming from VODS3, we see following:
RTSP:

In both cases, it does not play from VLC.
We are wondering what is wrong.
Can you please comment on this?
Thanks
