mpeg-dash - Application provided duration: -1056 / timestamp: 983056 is out of range for mov/mp4 format

[andreymal]

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 -seg_duration 2 dash/manifest.mpd
[dash @ 0x3b194c0] No bit rate set for stream 0
[mp4 @ 0x3bec8c0] Application provided duration: -544 / timestamp: 32528 is out of range for mov/mp4 format
[mp4 @ 0x3bec8c0] Application provided duration: -528 / timestamp: 80544 is out of range for mov/mp4 format
[mp4 @ 0x3bec8c0] Application provided duration: -528 / timestamp: 128544 is out of range for mov/mp4 format
... 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 ​#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:

$ ffmpeg -i dash_mp4_timestamp_error.flv -c:v copy -an -f dash -seg_duration 2 dash/manifest.mpd

The warning is shown since 51000b994514e64a6c5039e179f20c9e24f87c45

[andreymal]

Now I have access to another camera Hikvision DS-2CD2032-I with the same problem. It is always online, so I can test something at any time, if necessary. See attached dash_mp4_timestamp_error_hikvision.flv

Please run the recording of the flv stream with -loglevel debug and attach the log file here.

[andreymal]

ffmpeg -loglevel debug -analyzeduration 2 -rtsp_transport tcp -i rtsp://admin:123456@192.168.1.13/Streaming/Channels/102 -c:v copy -an dash_mp4_hikvision_debug.flv 2>&1 | tee hikvision_debug.txt

Replying to andreymal:

I checked the code, the error message is actually a kind of "warning", the information shows only when start a new segment and mean while the current packet->pts is smaller than duration. Ffmpeg will adjust the timestamp in this case. So I believe the disconnection may be caused by some other reason ?

Do you have more detailed logs ? Especially when rtsp drops connection？

[Jun Li]

The content looks like variable frame rate, could you try set the -r 30 on output ?

[andreymal]

Oh, the camera broke and is not available now :( I don't know when it will be repaired, so now it is difficult to answer. I'll try to experiment with other cameras, but I'm not sure that the problem will be reproduced

when rtsp drops connection

The rtsp connection was not dropped, only the mpeg-dash stream was broken

[andreymal]

Well, my Hikvision camera is online now, and I still have this problem. Now I tried this command:

ffmpeg -loglevel debug -debug_ts -y \
  -rtsp_transport tcp -stimeout 10000000 -i 'rtsp://admin:123456@192.168.1.13/Streaming/Channels/102' \
  -map 0:v -c:v copy -an -f dash -min_seg_duration 100000 -window_size 16 \
  -extra_window_size 4 -remove_at_exit 1 dash/manifest.mpd \
  -map 0 -c copy dash_mp4_timestamp_error_hikvision_2019.flv

The recorded video file and the log is attached. I can test and record something else if needed.

The content looks like variable frame rate

I want to keep variable frame rate as is. I also tried "-vsync passthrough", but the problem is still present.
