Hi! I know this is an old thread however I'm curious to understand if
any ffmpeg users are still interested in this capability. I'm testing
a tool we created for the genomics space to understand how broadly
usable it may be. Its linux only at the moment and uses ld_preload to
allow ffmpeg (or any tool) write to or read from any s3 storage
environment (aws in the cloud or ceph on prem). I'd like to understand
if this works with more complex ffmpeg usage examples as well. Any
willing tyre kickers welcome. Works for input and output files to
directly stream to / read from object stores.


[Example just cover input files / works for output fine also]

[root@deploy-ext ~]# LD_PRELOAD=/usr/lib/cuno.so bash
[root@deploy-ext ~]# ls s3://bucket1/
file_example_WAV_2MG.mp3  file_example_WAV_2MG.wav  file_output2.mp3

[root@deploy-ext ~]# ffmpeg -i s3://bucket1/file_example_WAV_2MG.wav
./output-dp.mp3
