How to read remote video on Amazon S3 using ffmpeg
- by virtualize
I need to create poster frames from videos hosted on Amazon S3 via ffmpeg.
So is there a way to use the remote video file directly in ffmpeg command line like this:
ffmpeg -i "http://bucket.s3.amazonaws.com/video.mp4" -ss 00:00:10 -vframes 1 -f image2 "image%03d.jpg"
ffmpeg just returns:
http://bucket.s3.amazonaws.com/video.mp4: I/O error occurred
Usually that means that input file is truncated and/or corrupted.
I also tried forcing ffmpeg to use the videos mp4 container for reading:
ffmpeg -f mp4 -i "http://bucket.s3.amazonaws.com/video.mp4" ...
But no luck.
Wget this video from S3 and processing it locally works fine of course,
as well as reading the file remotely from other 'standard' http servers.
So I know that ffmpeg supports remote file reading, but why not on S3?
