 I have an IP Camera: Falcon Eye FE-MTR300-HD. And I want to remux RTSP
 camera stream to MPEG-DASH stream for web browsers, but it breaks after
 few hours. I guess this error can be the cause.


 {{{
 $ ffmpeg -loglevel warning -i [input-stream] -c:v copy -an -f dash

 ... and many other lines, one per segment ...
 }}}

 I also tried `-avoid_negative_ts make_non_negative` and/or `-fflags
 +genpts`, but nothing changed.

 `ffmpeg ... -c copy test.mp4` or `ffmpeg ... -f segment %07d.mp4` works
 without errors, so I think this is dash bug.

 I do not exclude that the problem is in the camera and the stream may be
 broken, but I can't influence it. (Can ffmpeg fix the broken stream
 without transcoding, please? :)

 This problem affects any ffmpeg >=3.4 version, including latest
 git-2018-04-17-2fc12f4 (tested on Ubuntu 16.04 and Debian 8)

 P.S. Possible duplicate of [https://trac.ffmpeg.org/ticket/6778 #6778],
 but I can provide additional information; see attached
 `dash_mp4_timestamp_error.flv` to reproduce this (grabbed from original
 RTSP stream).

 P.P.S. Default loglevel, if you want:
