I developed a webserver using golang. There is no video loaded, if I try to hit it directly the browser just shows some video contols without loading the file:.
As suggested I also tried another video which is working perfectly fine! But let me explain what I finally did to get it working:. I tried to solve my problem without using the http. FileServe method. Therefore I implemented like so:. That worked for the first time I played the video. But since I want it to loop it should directly start from the beginning but it stuck at the very last frame of the video. The video is also playing in a loop correctly now.
But I still have no idea why ServeFile is working and the other method not though the response is exactly the same for both methods. Nevertheless the content is looking like that now:. I don't know the default buffer Chrome uses it may depend on multiple things like free memory, free disk space etc. One of your video is a few seconds shorter and almost 3rd the size of the other. Chrome buffers completely the smaller video likely in memorywhile does not do the same with the other. And since it's bigger than the buffer, it needs the server to support Range requests partial content serving.
You should serve your files using http. ServeFile which supports serving Range requests required for videos that are bigger than a certain size. See related question: How to serve http partial content with Go? Going forward, there is no practical reason not to use http. It won't load the complete file into memory as you did which is a really bad idea in case of big video files.
ServeFile handles Range requests if asked so, and also properly sets response headers including the Content-Type and knows that.
Learning the basics of video streaming with Golang
As you can see, the Go app reports the video size is around MB. ServeFile also includes the response header Accept-Ranges: bytes which lets clients know prior that we support Range requests. How does Chrome respond to this? Closes the connection after receiving 32 KB Chrome fires a Range request asking everything from the first byteso if your Go app does not support this, you're in trouble.
See response 2. ServeFile behaves well, and responds properly to the Range request HTTP Partial Content status code and Content-Range headerand sends the range that was requested everything in this case. If the video file is small, Chrome will not make a big deal out of it as it will just accept the HTTP OK response too and likely just store the small video in memory or in a cache file. Your code seems to work fine for me.
Well, since it's not a live stream in terms that the size and duration are known since the source is an mp4 file I think your server should honor the Range header in the request and respond with proper Content-LengthContent-Range and Accept-Range values otherwise seeking would be impossible and I guess you don't want that.
That should make Chrome happy. Take care when implementing the handling of the Range header value in the request - if it is not 0- then you must actually seek to the requested point and return the data from there.
Also I don't think videos should be transferred with Transfer-Encoding set to chunked.All of this started with an ambitious goal of creating a bidirectional video streaming service - something like a video call - using a gRPC server which I covered in my last post. However, this method is definitely not how most of the videos are available on the internet - partly because it requires the client to first fetch the entire video and then play it.
Imagine how this would play out in case of longer, heavier videos. Another reason this approach is avoided is because anyone can download your videos by simply going to the source URL. The solution to this problem is to send your video to the client in smaller packets and deliver more as the client plays through the video.
This is how most of the video streaming services such as YouTube, Netflix, Amazon Prime, Hulu, etc deliver their video content to their users. I need a way to split my mp4 file into smaller chunks and an index file with information about which chunk contains which segment of the video. This approach was heavily used across all Apple devices and later it became the common standard for streaming videos across the Internet.
HLS requires the videos to be encoded with H codecs. The output files will include The HLS. JS player first requests the index. Alright basics of gRPC and video streaming are clear. Now time to move on to a bigger challenge of doing all this automatically - user uploads a video file, a service encodes it into HLS or DASH, moves the HLS files into a cloud storage, and the streaming client requests the relevant video from the storage or a Content Delivery Network CDN.
I guess this is the proper way of solving big problems - break them into smaller problems which are easier to solve one at a time. Based in India. Building a few helpful things.

That is, it is for direct manipulation of Go modules themselves. It is NOT about supporting general development tools that need to do things like load packages in module mode.
The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.

It did not mention Pregame Action or Sharpbettor.
He declined multiple times to answer those questions, instead issuing a statement that did not address them.
Learning the basics of video streaming with Golang
After this story was published, he emailed me, denying involvement with Pregame Action and Sharpbettor. The bettor whose livelihood is dependent on having an edge can only be so helpful. If enough people get a whiff, the value is gone. It is counterintuitive that anyone good enough at betting sports to make money on it would ever publicize his picks, no matter the price.
Maybe Americans would like to believe that successful sports bettors resemble average joes more closely than they do the mathematicians, financial analysts, statisticians, and software developers who actually do this for a living. The real bettors, like Jacob Wheatley-Schaller, offer fewer absolutes, and less interesting soundbites.
It makes for great radio when Fezzik calls out his three-star game of the year, but far less exciting when a bettor explains that he bet three-quarters of a percent of his bankroll based on his perceived edge against the closing line.
And if revenge were a computable variable, bookmakers would have already factored it into the line. For poker magazine All In, he looked at more than 200 public handicappers and found that not one had a lifetime win rate of 55 percent.
The data showed that only about five percent of these touts could achieve a lifetime win rate of 52. Not much has changed since then, except now the hundreds of touts out there have a wider audience for their questionable logic. In a low-budget 2013 documentary on sports betting called Life on the Line, a group of sad-looking touts known as the Tuesday Group meet to discuss their ideas before the 2011 Super Bowl. I saw Tiger Woods get humbled, I saw Brett Favre get humbled, I think Roethlisberger on the biggest stage of the world is gonna get humbled.
Later in the film, Covers mocks a young bettor for not being able to show him a spreadsheet of his allegedly excellent results. This explains why Bell almost never mentions Fezzik without including his past glory: back-to-back NFL contest wins from 2008 and 2009. In recent months, Bell has circled the wagons around Fezzik, his flagship pick-seller. Eichenlaub wrote that he found several errors in its grading and record-keeping early on, when Johnny Detroit was in charge of the records.
Bet Like a Pro was, according to Pregame, up 26 units year-to-date when Eichenlaub stepped in on August 7, 2015. Since then, it has taken a 14-unit loss. With Johnny Detroit and Jeff Scott Sports everything was fine, then Bob tracks and everything goes to crap.
Bell encouraged his customers to buy subscriptions and not daily selections, thus bringing down the cost of each pick. My personal picks are also monitored daily by an independent documenter. Plus, a dedicated Pregame forum thread is prominent for anyone to report any pick grading or win streak mistakes, ensuring that necessary corrections are publicly made. No other pick selling site even comes close. A few months ago, four apparently clandestine recordings of a meeting purporting to be between Bell and his touts were posted online.
Did Deadspin confirm authenticity. Did Deadspin demand to hear the full context. A person purported to be Fezzik says average bettors are picking at 50 percent on their own, but after paying for a pick from a tout, they might win 53 percent of the time. Say you only buy three picks a week, three packages a week. How many months does that go on. One day soon, sports wagering will be permitted from coast to coast.
