streaming

问题 I am a newbie in video streaming and I just build a sample website which plays videos. Here i just give the video file location to the video tag in html5. I just noticed that in youtube the video tag contains the blob url and had a look into this. I found that the video data comes in segments and came across a term called pseudo streaming. Whereas it seems likes the website that i build downloads the whole file and plays the video. I am not trying to do any live streaming, just trying to

问题 If I have a use case where I need to join two streams or aggregate some kind of metrics from a single stream, and I use keyed streams to partition the events, how does Flink handle the operations for hot partitions where the data might not fit into memory and needs to be split across partitions? 来源： https://stackoverflow.com/questions/66273158/how-does-flink-scale-for-hot-partitions

问题 how to load data from AWS RDS to Google BigQuery in streaming mode? Description: I have data in RDS (SQL Server), and wanted to load this data into Google BigQuery in real-time. 回答1: There is no direct way to insert changes from Amazon RDS to Google Cloud BigQuery. It could be done with a pipeline like this Amazon RDS ----Lambda/DMS----> Kinesis Data Streams -----Lambda----> BigQuery Read changes from Amazon RDS to Kinesis Data Streams using Lambda or use Cloud DMS. You can also push it to

问题 Let's say that I have a list of hundreds of possible video files. Using ffmpeg it's pretty easy to take multiple files and stitch them together to single video output, but that's where the things become tricky. I'm looking for a way to have them stream live and dynamically add videos to queue as stream goes on. Think of something like SSAI but for the whole video. Stream live is there so we don't have a delay while waiting for ffmpeg to finish the whole video but rather start as soon as

问题 I was trying to use an Arch solution for streaming to twitch today through FFMPEG, but all of my attempts were in vain because of one simple thing on FFMPEG. it says that the probesize is not large enough, so I instinctively increased the probesize value more and more... and now it is -probesize "500M" yet it is still saying it is not enough. here is the code snippet [x11grab @ 0x5631f846cd00] Stream #0: not enough frames to estimate rate; consider increasing probesize Input #0, x11grab, from

问题 I have some large binary files stored in Google Cloud Storage that require byte by byte processing. I would like to do this processing using a Cloud Function, but this would require streaming the binary data through the cloud function. Does anybody have any idea how to do this. I'm using Python 3.7. 来源： https://stackoverflow.com/questions/60273469/streaming-binary-data-from-google-cloud-storage-to-cloud-function
