• How to provide video streaming option for different formats on website

  3 avril 2014, par kami998

  In my website users can upload different video formats and i need to provide streaming for those formats (for example : mkv, avi, mp4, 3gp, wmv), but on web only mp4 format can be played by flash players.

  My videos are hosted on amazon s3 server while my webserver is on different location, what i do is receive stream from s3 and transmit to client, so what i need is to convert the video format to mp4 on the fly

  So, is there any possibility to perform this functionality ( i am using asp.net mvc webapi as streaming service )

  Any sort of help is appreciable...

• FFMPEG and HTTPS

  14 juin 2012, par Joel

  ffmpeg lists http as a protocol when I ask : ffmpeg -protocols

  Does this also mean support for a https url ? Do I need to encode this url somehow for the command line. I get "No such file or directory", but with http urls (at least some) it does work.

  A url (created for a Amazon S3 bucket) similar to this one does not seem to work :
  https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&Expires=1323709667&Signature=pTvS9F2do2t8%3D

  I suspect the format of the url is problematic, I've also tried enclosing in quotes... Yes, this URL does not currently work as it has expired, but even while its valid, its a problem.

  In short :
  1) Should https work ?
  2) Do I need to format the url somehow ?

• Download Partial Video via HTTP (for Remote Thumbnailing)

  13 février 2012, par HuntedC

  I have videos hosted on Amazon S3. I encode them with Zencoder and store a thumbnail for the video then using Zencoder. However, I need a way to generate thumbnails at certain points in the video (i.e. 00:00:03, 00:10:32, 01:40:18) and store them either on S3 or my server.

  ffmpeg allows remote thumbnailing, however it takes a very long time (sometimes several minutes) to get a thumbnail from the middle of a file—I believe this is because it downloads the entire file up to that point to get the thumbnail.

  My plan is to somehow download the header of the video file via HTTP byte-range request, guesstimate the byte range where I should be looking for the thumbnail, download about a second of video from that part of the file via HTTP byte-range request, then save the header and tiny video locally. I pull the thumbnail from that using ffmpeg and delete the temporary video.

  I have no idea on how exactly this would work (I believe the H.264 MP4 files I'm working with have a dynamic length header, for another issue). Any suggestions or better ideas ?

  Edit : To clarify, Zencoder thumbnailing is great, but they only allow thumbnail creation in combination with transcoding. I don't want to transcode my video every time I create a new thumbnail, so I need to do this on my own without Zencoder.
