Hi,
I found the issue. I compared the logs generated by ffprobe of the streams
of one working video using the decoding/re-encoding elements and non-working
video. This is the diff of the two log files

30c30
< avg_frame_rate=109500/3667
---
> avg_frame_rate=1236000/41417
32,36c32,36
< start_pts=-1
< start_time=-0.000333
< duration_ts=7334
< duration=2.444667
< bit_rate=1985134
---
> start_pts=0
> start_time=0.000000
> duration_ts=41417
> duration=13.805667
> bit_rate=1968052
39c39
< nb_frames=73
---
> nb_frames=412
53c53
< TAG:creation_time=2018-04-11 08:26:33
---
> TAG:creation_time=2018-04-11 08:37:46


So, from the diff we can see that start_pts time is -1  and start_time is
negative for the non-working video. So can you please tell me why start_pts
and  start_time is getting invalid or how can I fix this?
