How to resolve a "MAX_FRAGMENT_DURATION_REACHED" error when trying to stream RTSP camera feed into KVS

[tawiemadavz]

I have been trying for a few days to connect a HikVision camera that is on my home network to KVS and if keeps failing with error message "MAX_FRAGMENT_DURATION_REACHED".

I have tried to adjust the camera settings for my IP camera to try get the GOP (as i understand it) as low as possible but still facing the same issue.

I am running the latest docker file for this build on an M1 Mac. I have used VLC player and ffmpeg to double check if the stream is working and it is working fine.

I have used the following commands to try start the stream:

./kvs_gstreamer_sample FacialVideoStream rtsp://XXXXXX:XXXXX@IP/Streaming/Channels/101

and

gst-launch-1.0 rtspsrc location="rtsp://XXXXXX:XXXXX@IP/Streaming/Channels/101" short-header=TRUE ! rtph264depay ! h264parse ! video/x-h264, format=avc,alignment=au ! kvssink stream-name="FacialVideoStream"

Credentials were set i have just omitted them and commands were pointed to the correct region.

See below camera settings and logs. Any help would be appreciated. Thanks!

Hi @tawiemadavz, can you try #147 (comment) if it helps

[tawiemadavz]

@niyatim23 i had seen it earlier, but i'm confused as to where on this command i should add "key-int-max=10"?

Original Command:

gst-launch-1.0 rtspsrc location="rtsp://XXXXXX:XXXXX@IP/Streaming/Channels/101" short-header=TRUE ! rtph264depay ! h264parse ! video/x-h264, format=avc,alignment=au ! kvssink stream-name="FacialVideoStream"

When i add "frame-timestamp=1":

gst-launch-1.0 rtspsrc location="rtsp://XXXXXX:XXXXX@IP/Streaming/Channels/101" short-header=TRUE ! rtph264depay ! h264parse ! video/x-h264, format=avc,alignment=au ! kvssink stream-name="FacialVideoStream" frame-timestamp=1

Output:

WARNING: erroneous pipeline: no property "frame-timestamp" in element "kvssink"

When i add the "key-int-max" from "x264enc":

gst-launch-1.0 rtspsrc location="rtsp://XXXXXX:XXXXX@IP/Streaming/Channels/101" short-header=TRUE ! x264enc bframes=0 key-int-max=10 bitrate=512 ! video/x-h264, format=avc,alignment=au ! kvssink stream-name="FacialVideoStream" frame-timestamp=1

Output:

WARNING: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: Delayed linking failed. Additional debug info: subprojects/gstreamer/gst/parse/grammar.y(919): gst_parse_no_more_pads (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: failed delayed linking some pad of GstRTSPSrc named rtspsrc0 to some pad of GstX264Enc named x264enc0 ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: Internal data stream error.

So it does not seems to be working for me because i'm using "rtspsrc" instead of "ksvideosrc". Not sure if that matters? Have a limited understanding of gstreamer so any assistance RE how to put together the command correctly would be appreciated.

Thanks!

@tawiemadavz ,

Please follow the example here: https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/blob/master/docs/linux.md#running-the-gst-launch-10-command-to-start-streaming-from-a-rtsp-camera-source

We have some sample pipelines in our docs that could help you get started.
