How do I prevent files from being saved to that path?

[chanung-ki]

I am using ffmpeg-python to transcode mp4 files.

I would like to immediately upload the converted video to the s3 bucket using the SDK without saving it to a local path.

However, when you execute the run() function, it is immediately saved to the specified path. If I do this, I have to repeat the process of reloading the file, uploading it to the s3 bucket, and deleting the file.

So, I would appreciate it if you could share a way to assign the files output when executing the run() function to variables.

How do you upload to s3? s3 reads from a file, you'll have to store it at some point (if you are working with Lambda you are free to use the /tmp folder).

s3 support direct bytes stream, but that's for local (and small) objects. FFmpegdoesn't run in your Python interpreter. ffmpeg-python translates your Python code into command for ffmpeg, it doesn't process any data.

Moreover, I imagine your mp4 files are not a few bytes large, you surely don't want to store it in a local variable. That would eat up all your available memory...

If you really want to go that way, you'll have to find a way to store a video inside a Python variable (and advise you not to do so).

May I know why you don't want to store the output of ffmpeg locally? We could find a more appropriate solution 👍

Looks like you can use pipe: too, see https://kkroening.github.io/ffmpeg-python/ and https://github.com/kkroening/ffmpeg-python/blob/master/examples/README.md#convert-sound-to-raw-pcm-audio
