Audio Extraction takes extraordinarily long to extract audio from multi audio track video (1hour in length)

[jurassicjordan]

Bug description

AutoEditor seems to get stuck or freezes when extracting audio, taking about an hour just for one track.

What's your platform?

Python Version: 3.11.9 64-bit
Platform: Linux 6.8.5-zen1-1-zen x86_64
FFmpeg Version: 4.2.2
FFmpeg Path: /home/jordancruz/anaconda3/envs/AutoEditor/bin/ffmpeg
Auto-Editor Version: 24w13a

running under conda because my primary install of python is 3.12, which is too new.

What command did you use

auto-editor /run/media/jordancruz/WorkDrive/Video Workspace/Footage/2023-01-26_22-44-33.mov --edit audio:stream=all --export resolve

and

auto-editor /run/media/jordancruz/WorkDrive/Video Workspace/Footage/2023-01-26_22-44-33.mov --edit audio:stream=all --export premiere

What properties does your input video have?

Comments

It has been a while since I've used auto editor, but I don't remember it being this long of a wait

Your ffmpeg is too old. Use ffmpeg 6. We support Python3.12 now. I'm not suprised it's taking so long because of codec: mjpeg and pix fmt: yuvj420p. You should use more normal formats like h264 and aac and let your hardware accel do the rest, which should be used by default.
