Complete, uncut console output missing.
Sorry about that. The following are console outputs from the client with
and without the "*itsoffset*" option:
==========================================================================================
*1. **ffmpeg -y -i **http://192.168.0.11:8090/VIDEO_CAM1.mpg**-i
**http://192.168.0.11:8090/AUDIO.mp2**-map 0:0 -map 0:0 -t 15 test.mp4

I would also like to share my "*ffserver.conf*" and "*input ffmpeg
commands*"
==========================================================================================
*1. ffserver.conf
* https://www.dropbox.com/s/cf3kgyfimq6dgcr/ffserver.conf?dl=0*
*
*2. ffmpeg input commands (to ffserver)*

==========================================================================================
Hope this helps in getting further insight.
Unfortunately, I suspect your http sources do not provide timestamps,
so there is no easy solution;-(
I see. The stream that seems to always start at *dts=0* is the audio stream.
Please refer to the following outputs of ffprobe:
==========================================================================================
*1. ffprobe -i http://192.168.0.11:8090:AUDIO.mp2 -show_frames*
- https://www.dropbox.com/s/xb5t88rc3vdyc0y/ffprobe_audio.txt?dl=0
- pkt_dts and pkt_pts always start at 0
*2. ffprobe -i http://192.168.0.11:8090:VIDEO_CAM1.mpg -show_frames*
- https://www.dropbox.com/s/ywxgznv8xjbqozj/ffprobe_video.txt?dl=0
- pkt_dts and pkt_pts always start non-zero
==========================================================================================
I think that the solution is to add timestamp to the audio stream. But I
already tried
using the "*use_wallclock_as_timestamp*" option in ffmpeg audio feed.
Nothing happened.
Is there any other way to do this?
I am very sorry for the inconvenience. I am not much of a programmer,
but more
of an enthusiast. I am using FFmpeg in my home for personal security and
surveillance.

Guillermo Martinez
