I'm building a web application that allows people to download videos from my site that's stored in Amazon S3. It's going great so far, save for the fact that when I download the video stored in S3, it appears to be slightly more pixelated and fuzzy than the same video that has not been uploaded. The videos are in mp4 format and around 150 mb big. I upload them using S3's web uploader. Does anybody know what is going on and how to fix this? I want my customers to have the best quality possible.
Amazon S3 shouldnt do anything to the video quality. Perhaps it is the player you're using? Perhaps try a different flash player like JW Player, as the only possible reasons (i can think of) the quality would be going down is either due to the flash player or the actual embedding of the video.

I am creating as my own project a mobile app. One of the functionalities of the application is uploading video files (up to 500mb) and watching uploaded videos by other users.
I was thinking about various server solutions and how many people have so many opinions. Unfortunately, it is hard for me to find someone among my friends who knows the topic well and would be able to advise. For the beginning, I think it makes sense to use AWS (but I've never done it) and I would like to ask you (if I can) for advice.
In step one I upload a video file to AWS S3 via the application
AWS MediaConverter compresses the video file, the old one is removed and replaced with a new one (Elastic Transcoder is very expensive)
In the application, I can paste direct links to s3 which I can use to serve videos.
As far as I understand, I don't need any other services than AWS S3 and AWS MediaConverter.
Or maybe I am thinking wrong and using amazon for this does not make sense?
Thanks!
I am trying to create a video sharing app for only one country (India). My bucket is in the India region. The size of videos will be of approximately 18MB each.
The video download takes too much time (~4mins) to download even via CloudFront. How can I accelerate my S3 download speed?
Apps that play streaming video do not download an entire video file before playing. Rather, they use a video protocol that only downloads a few seconds at a time. Amazon CloudFront can support these protocols, such Adobe's Real-Time Message Protocols and Microsoft Smooth Streaming.
See: How RTMP Distributions Work
Therefore, the time for the actual file to download is not important. Rather, the time to serve the first portion of the video is most important, followed by the ability to continue serving content as fast as the viewer consumes the content.
Connections speeds will, of course, vary depending upon each user's own Internet connection -- therefore, it is best to test the speed of your application's video playing ability from many different ISPs and types of Internet connections.
I need to include 42 tutorial videos on a single web page, between 30-90 seconds each. I'm currently uploading them to S3 in mov format and including them in the page with the video tag. 6 videos in, the page loads fast enough but the videos take ages to load.
It looks like I have 2 options to speed this up from the research I've done -
1 - Upload the videos to Youtube, load thumbnail images on the website and replace them with the video when the user clicks on the thumbnail image.
2 - Use Amazon CloudFront to deliver the videos to the user.
Which of these is a faster way of delivering videos to the user? Youtube seems to be the cheaper option with the added advantage of allowing the user to stream videos on Youtube but AWS CloudFront seems like a service specially built for this purpose.
I will suggest if you want less complexity and fast setup use You Tube. Even if AWS CF is build for this purpose you will have to create a infrastructure for hosting those videos, which in case of you tube you have to just embed the video using the embed code.
As per costing goes Youtube is less cheaper almost free. If you create Cloud Front for the distribution you have to pay for Storage of the Videos, Data Transfer Cost and many more. You will get a very good speed for youtube videos worldwide. Also you have to create a video player in your application for video streaming which is again more work.
I have a model that uses "models.FileField()", which I then display back to the user so they may click the link and have a file rendered in their browser. The user can upload various types of files.
Problem is, I'd like to handle large avi's differently, and have the file stream to the user.
The requirement I have is to simply stream/transcode video files from the media_root dir to an end user's browser, preferably in a mac friendly format. It would be for a couple users at most.
I've search and stumbled upon a few projects:
https://github.com/andrewebdev/django-video
https://github.com/rugginoso/django-transcodeandstream
As I am I a relatively newbie when it comes to django, I'm not sure how to incorporate their code into my proj.
Any thoughts, suggestions?
You can check Amazon Elastic Transcoder. It is a media transcoding in the cloud. It is designed to be a highly scalable, easy to use and a cost effective way for developers and businesses to convert (or “transcode”) media files from their source format into versions that will playback on devices like smartphones, tablets and PCs.
Or else you can check Webfaction, they have Video and image processing on their servers which you can use.
If you will use any of those, you can ask them about the installing process and how to integrate it in your project.
And one more thing, if you want to play the video on the browser, you will need a video player like jwplayer.
Hope this will help you get started! Best wishes!
I'm looking to stream video's as part of a django app, but I've never done anything with video and don't really know where to start. I don't have all the details of the project yet, but I'm expecting a fairly small library of videos uploaded by one or two people (Think less than 100 videos of about 5 mins length).
I'm looking for a solution that allows users to upload videos using django admin. I want to reach the majority of desktop browsers (95%+), and obviously I want to keep my costs down. Saying that I do like the idea of using some sort of cloud based CDN (I've no idea if that's possible / appropriate for this size of project)
I really want to ask if anyone can point me int he right direction (tutorials / services / projects / code), but I realise that might not be specific enough.
So to be more specific -
Is it possible to stream video to browsers using just django and an apache web server?
What cloud hosting providers will support easy integration with a django app?
Will I need to convert the format of my video's before they're ready to stream?
Can I use Red5 with a cloud hosting solution.
I want to host the project on a Ubuntu server that I use to host a
couple of other (low traffic) django apps - would it be a mistake to install Red5
on a server with existing sites.
From recollection, the server has 12GB RAM and 4 cores (in a 1and1
uk datacentre). Will I have enough power / bandwidth to stream say 3-5 video's simultaneously? (assuming red5 / wowza).
I'm not interested in Flash because I was rooting for Apple. Do I
need to need to re-evaluate my prejudices to be free of my ignorance?
I never streamed videos using Django/Python, but I have some experience in the field of streaming video in frontend apps. I can certainly not answer all your questions. In my experience it does not really matter where the video is hosted, a CDN is fine if you want to distribute the video world-wide.
I personally think you should start with the question on how you want to play the video in the browser. Choose an appropriate video player (could be html5 video) and you have an idea of what is possible to play and what not.
3) The format matters depending on how you want to stream the video. Progressive download (e.g. mp4)? Live streaming (unprogressive, e.g. HLS)? You can find example videos online and test if your video player can play the videos on the platform you want to support.
7) As said, you need to check out which player to use in this case. HTML5 video is not widely supported enough yet in my opinion, but can play most formats in the most modern browsers (Chrome, Safari).
Hope that helps.
