Amazon Kinesis Firehoseって？何が嬉しいの？ |

|
ただLamdaの場合はログを加工する関数が予め用意されていたりするので、これらを使うとかなり開発時間を短縮できて便利ですCAUTION分析する時は別のサービスが必要AmazonKinesisFirehoseはあくまでも加工して保存するまでがスコープのサービスなので、その保存したデータに対して分析する場合は別のサービスを利用する必要があります例えば、AmazonGlueとAmazonQuickSightの組み合わせや、Sに保存するのではなくDatadogに保存するようにする、などですここら辺もまた勉強したらシェアしたいと思います。 |

Building a Live Streaming app in Clojure |
https://dev.to/dvliman/building-a-live-streaming-app-in-clojure-329m
|
Building a Live Streaming app in ClojureI want to echo John Carmack s tweet that all giant companies use open source FFmpeg in the backends FFmpeg is a core piece of technology that powers our live streaming and recording system at Inspire Fitness It certainly is high quality open source software that we use to record and stream countless hours of workout videos It looks like this Users can watch live streaming content orplayback on demand videos from our content libraryHigh levelBehind the scene we have IP cameras are wired up in each studio room The cameras support the RTSP protocol A software pipeline integrated with our custom CMS to broadcast stream our cameras feed to the internet while simultaneously recording and storing the content to AWS S storage for on demand playback How it all works together We configure classes the recordings to start at a particular time in our dashboard The time aligns with our studio schedules where gym members would often join our classes to work out alongside the instructors We kick off a dedicated ec instance with FFmpeg baked in an AMI image when the class starts We call this our encoder transcoder vm clj aws invoke state ec op RunInstances request InstanceType cd xlarge MaxCount MinCount SubnetId subnet id ImageId ami id SecurityGroupIds sg id UserData build user data class id TagSpecifications ResourceType instance Tags Key Name Value make class name class id As soon as the ec boots up it runs the cloud init script which starts the Clojure process and mount a state management library that would then starts the dependencies core clj defn run encoder mount start state s state db encoder encoder defn main amp args run encoder This would in turn calls start stream encoder clj defstate encoder start try start stream catch Exception e error handling here stop stop stream The start stream logic is actually pretty simple It pulls feed from our camera and egress out our CDN partner defn start stream record encoder connect to camera make event details manager register connect to camera sh proc ffmpeg hide banner re rtsp transport tcp i config encoder rtsp endpoint c a aac ar b a k c v h profile v high g keyint min sc threshold b v k maxrate k vcodec libx bufsize k hls time hls playlist type event hls segment filename segment file pattern manifest file path redirect stdout stderr connect to camera hls file path it takes some time to pull from the RTSP stream and write to the mu file the HLS egress looks at the mu file if it can t find it the process will exit so wait for the file record encoder wait for manifest file make event details record encoder egress make event details manager register egress sh proc ffmpeg hide banner re i manifest file path c v copy c a aac ar b a k f flv config encoder ingress endpoint redirect stdout stderr egress egress file path The output would be a playback URL that our video player would be pulling from Notice we are essentially invoking the FFmpeg that we bundled earlier to take input from RTSP transport protocolargument flags for the video audio codecFlagWhat it does reread input at native frame rate Mainly used to simulate a grab device i e if you wanted to stream a video file then you would want this otherwise it might stream too fast c a aactranscode to AAC codec ar set the audio sample rate b a kset the audio bitrate c v h or copytranscode to h codec or simply send the frame verbatim to output hls timethe duration for video segment length f flvsays to deliver the output stream in an flv wrapperrtmp is where the transcoded video stream get pushed toThe code is essentially a shell wrapper to FFmpeg command line arguments FFmpeg is the swiss army tool for all video audio codecsThe whole encoder clj is about lines long with error handling It handles file uploads video segment files FFmpeg logs for debugging egress to primary and secondary fallback RTMP slot shutdown processes and the ec instance when we are done with the recording Lesson learnedThis was a rescue project from Go to Clojure The previous architecture had too many moving pieces making HTTP requests across multiple micro services The main server would crash daily due to improper handling of WebSocket messages causing messages to be lost and encoder instances not starting up on time The rewrite reduced the complexities Simple Made Easy as Rich Hickey Rewriting a project is never a good approach considering the opportunity cost I evaluated a few offerings mux com Cloudflare Stream Amazon IVS On paper they have all the building blocks we need In addition some have features like video analytics policing signing playback URL which would be useful for us Ultimately the fact that we still had years contract with the CDN company was why we still manage our encoder In hindsight if we consider the storage costs and S egress bandwidth fee on top of the CDN costs I would probably go for ready made solutions for our company stage I would start optimizing when we have more traffic The good thing is that this system works really well for live streaming workload with programmatic access Sidenote barring occasional internet hiccups in our studio If you have a video production pipeline that involves heavy video editing going with prebuilt software could be more flexible until you solidify the core functionalities Special thanks to Daniel Fitzpatrick and Vincent Ho My coworkers helped proofread this article and maintain the broadcast system I enjoy working with you both ️ We even have automated tests to prove the camera stream is working end to end Neil our product manager understands tech trade offs and works with me to balance the product roadmap Daniel Glauser who hired me for this Clojure gig |
