Im very new to Api and our use case is to stream the live data from webcam to kinesis video stream (kvs).
Steps Taken : Created the ubuntu server on aws and installed the CPP SDK.
created the kinesis video stream in aws
downloaded and installed the Gstreamer on my local.
I was trying to put the rtsp sample data to gstream which is on Ec2ubuntu server server i ran below query
$ gst-launch-1.0 rtspsrc location="rtsp://YourCameraRtspUrl" short-header=TRUE ! rtph264depay ! video/x-h264, format=avc,alignment=au ! kvssink stream-name="YourStreamName" storage-size=512 access-key="YourAccessKey" secret-key="YourSecretKey" aws-region="YourAWSRegion"
im getting attached error may be we need to open some port on ec2 ?
Suggestion required :how can i put my local webcam video to kinesis ?
thanks
If you use macOS, you can stream your webcam into Kinesis Video Stream like the command below setting fps 1;
AWS_ACCESS_KEY_ID=<YOUR_AWS_ACCESS_KEY_ID>
AWS_SECRET_ACCESS_KEY=<YOUR_AWS_SECRET_ACCESS_KEY>
AWS_REGION=<YOUR_AWS_REGION>
STREAM_NAME=<YOUR_STREAM_NAME>
gst-launch-1.0 -v avfvideosrc \
! clockoverlay font-desc="Sans bold 60px" \
! videorate \
! video/x-raw,framerate=1/1 \
! vtenc_h264_hw allow-frame-reordering=FALSE realtime=TRUE max-keyframe-interval=2 bitrate=512 \
! h264parse \
! video/x-h264,stream-format=avc,alignment=au \
! kvssink stream-name="${STREAM_NAME}" storage-size=512 \
access-key="${AWS_ACCESS_KEY_ID}" \
secret-key="${AWS_SECRET_ACCESS_KEY}" \
aws-region="${AWS_REGION}" \
frame-timecodes=true \
framerate=1
It's not immediately clear from your question what your scenario is. I assume if you refer to a webcam then it's attached to your computer. Depending of your use case, you could check out the producer libraries that will help integrating.
Java: https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-java
C++: https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp

You could ask relevant questions and get support in GitHub by cutting an Issue in the appropriate repository
I have this gstreamer command that plays stream from one Ubuntu 16.04 box but two others.
As far as I know I have same packages installed regarding gstreamer on all boxes because I ran sudo apt-get install gstreamer1-0* so that all gstreamer 1.0 packages are installed. I find it strange that it does not work on other
Following commands where used:
gst-launch-1.0 rtspsrc location=rtsp://<user>:<password>#<IP>/axis-media/media.amp user-id=root user-pw=xxxxxxxxxxc latency=150 ! decodebin max-size-time=30000000000 ! videoconvert ! autovideosink
or
gst-launch-1.0 playbin uri=rtsp://<user>:<password>#<IP>/axis-media/media.amp
This will open a stream of a Axis camera with h264. I don't understand why it does not work on two Ubuntu 16.04 boxes but works on one. All of these are the same Ubuntu 16.04 with same gstreamer packages installed.
Could there maybe be another package except gstreamer that is necessary in order for gstreamer to stream rtsp?
The error a get when it is not playing

Found the command from this webpage:
http://gstreamer-devel.966125.n4.nabble.com/gstreamer-client-pipeline-to-view-video-from-AXIS-M1054-Network-Camera-td4667092.html
Well it seems that it was the proxy that caused the issue. When I disabled proxy I was able to stream with gstreamer on all boxes.
Best regards
I'm using Sidekiq to queue up some jobs in my Rails server. As per the Logging wiki, it's as simple as adding the following in config/sidekiq.yml
---
:verbose: false
:pidfile: ./tmp/pids/sidekiq.pid
:logfile: ./log/sidekiq.log
:concurrency: 25
However, now this only logs to that log file, what if I do want to write out to STDOUT as well (atleast in development)?
Get rid of the logfile statement.
bundle exec sidekiq | tee ./log/sidekiq.log
Here what i am getting :
Counting objects: 10, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (8/8), done.
Writing objects: 100% (10/10), 3.60 KiB, done.

Earlier i thought it was problem of .gitignore file but that also working fine . I have ingnored my virutal env and *.pyc as given in documentation.
I tried :
heroku create --stack cedar
also I had to add my pub key to heroku.
heroku keys:add ~/.ssh/id_rsa.pub
this is also not able solve my problem.
I don't know much about the heroku implementation. Anything specific I should check or try?
Please help me as i referred many documents but still getting same error . Thanks in advance :)
I believe cedar recognizes django apps by the existance of a requirements.txt file.
Pleaee check is to be sure you have created 'requirements.txt' and 'Procfile' in the root of your source tree that is being pushed. The names are case sensitive.
