[FFmpeg-user] FFMPEG output to HTTP

[Farid Zakaria]

Pretty sure it would work as is if ffmpeg supported different method
actions for the output.
The docs make it sound like it only does when acting as a server.

I'll try to see in code where HTTP method type is hardcoded.

Having input and output straight from/to S3 would be a great demonstration.
Would make transcoding pipelines much simpler.
