Internal data stream error about amazon-kinesis-video-streams-producer-sdk-cpp

[MushMal]

@backdoorcodr, I am not familiar with this particular code - it's in GStreamer. Let me try to reproduce your scenario here locally by setting up a box and I will have a better understanding.

Apologies for this but it seems that the GStreamer pipeline might be hitting this issue on Ubuntu.

Hi backdoorcodr,

Given you were successfully able to stream using Java SDK :) are you still facing issues with CPP SDK? Please use the latest SDK in that case.

Thanks

@backdoorcodr any luck in trying this out? There is a couple of updates to the GStreamer sample application which applies ranges to the resolutions which might resolve the negotiation issue you were seeing.

Please give it a try.

Can you validate if your camera is detected? Could you please run
ls /dev/video0 - the output should list the device.

Not sure entirely but this could be caused by the camera USB driver. Can you try some other applications and see if they detect the camera OK. Here is a link to a page with some debugging info: https://help.ubuntu.com/community/Webcam

@MushMal this is what I was suspecting as well; therefore I did that earlier (plus after your response one more time just to be sure). I was able to find video0 as a response from this command.

Furthermore, I followed the link you provided and tested if the camera works or not. I chose cheese, vlc and streamer; and they all seem to be working quite well. hwinfo also seems to be accessing the camera and providing the details of it as well.

Can there be any other possibility or reason? What is -4 code mentioned in the error?

I went to the line 2939 of gstbaserc.c and understood that once it gets a null_buffer, it throws error that "internal data flow error". May be there what we need is to have some waiting time for the stream or the user kills the process himself? Just a suggestion.

Looking forward to your reason behind this error message and hints / suggestions to resolve it.

Many thanks

@MushMal Many thanks. that will be great. Let me know how it goes.

@unicornss @MushMal sincere apologies for replying back late. I have been on vacations. Let me try it out this weekend and let you guys know. Although, yes I have been successful to stream using the Java SDK.

Glad to hear that @backdoorcodr

@unicornss @MushMal Latest SDK resolves this issue :) Many thanks for this great support.
