Kinesis Video Service API request putMedia times out with no HTTP code depending on camera

Question

Hi, we're having some issues with sending up an RTSP stream to KVS. 
* We have a few cameras on site: One camera (model AXIS M3206-LVE) works and the other (model AXIS P1448-LE) does not. Both of them are updated to latest LTM firmware. Cameras are on timezone GMT+1.
* Both are on the same network and under the same firewall rules, the RTSP link is the same. 
* I am using the example ```kvs_gstreamer_sample``` from the [CPP producer SDK](https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/blob/master/samples/kvs_gstreamer_sample.cpp) with no modifications. 
* Running this sample application on an EC2 instance of type t2.micro on us-east-1.
* Streaming to a KVS instance on us-west-2. 
* This application setup works with a public RTSP test stream (```rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4```).
* The RTSP stream works on VLC no matter what camera.

The core problem appears to be the API request ```putMedia``` which times out after 30 seconds with HTTP code 0.

I've tried lowering factors like resolution and bitrate to minimums but get the same behavior everytime.

Could we be hitting a KVS limit of some kind? Is there a significant camera setting that may be different between the two?

Answer

Hi, The video track of each fragment must contain codec private data in the Advanced Video Coding (AVC) for H.264 format or HEVC for H.265 format (MPEG-4 specification ISO/IEC 14496-15). For information about adapting stream data to a given format, see NAL Adaptation Flags. 
I would start with extracting the camera settings that work and make a comparison with the setting of the camera which does not work (in the encoding section). you are using two different models and each might very well use a different encoder. 
Then I will look into the networking: your second camera is connected to the same circuit? You might have networking issues - did you try to use the nonworking camera on the same port instead of the working one? 
If identical, you might have issues with fragmentation; check the gstreamer. You might have to modify gstreamer parameters to get it working with your rtsp camera
