movie2usb

Copies movies to USB drives with verification.

Note: Device size validation protects against accidentally formatting the wrong drive.

Steps

1. Create/read SHA1 checksums from film directory
2. Read meta file for stick_label
3. Validate device size, format as ExFAT
4. Mount to <mount-dir>/<device_id>
5. Copy files (skip existing verified)
6. Verify checksums
7. Retry failed files (up to 3x)
8. Print summary, archive log
9. Unmount
10. Prompt for next stick

Requirements

• macOS (uses diskutil)
• Film directory with movie files
• Meta file with stick_label = "..."

Usage

# List matching USB devices
movie2usb --ls

# Process a device
movie2usb /dev/disk4

# Custom stick size (32GB ± 4GB)
movie2usb /dev/disk4 --stick-size 32.0 --size-tolerance 4.0

# Custom paths
movie2usb /dev/disk4 --film-dir ./movies --meta-file ./config.toml

Options

Option	Default	Description
--ls	-	List USB devices matching size range
--stick-size	16.0	Expected USB stick size in GB
--size-tolerance	2.0	Size tolerance in GB (±)
--mount-dir	/tmp	Base directory for mounting
--film-dir	./film	Directory containing movie files
--meta-file	./film/.meta.toml	Path to meta.toml file

• Real-time output grid for parallel processing (right panel)
• Auto-scroll output cells to show latest logs
• macOS notifications on completion

Controls

Key	Action
↑/↓ or k/j	Navigate device list
Space	Toggle selection and advance
Ctrl+A	Select all devices
Enter	Start processing selected devices
Ctrl+R	Refresh device list
q	Quit

Usage

# Start TUI with defaults
movie2usb-tui

# Custom stick size
movie2usb-tui --stick-size 32.0 --size-tolerance 4.0

Options

Same options as movie2usb (see above), except --ls which is not applicable.

Build

ffmpeg tricks

to split a movie to 2gb parts:

ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex \
    "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map \
    "[outa]" -segment_time 2000 -f segment -reset_timestamps 1 output_%03d.mp4
 
# or for single input:
ffmpeg -i input.mp4 -c copy -map 0 -fs 2000000000 -segment_time 99999 \ 
    -f segment output_%03d.mp4

Notes

On macOS by default a EFI partition is created on USB sticks, which causes 2 partitions to show up. The GPT confuses DVD Players and smart TVs. To avoid this, you can create a single partition scheme with diskutil:

diskutil eraseDisk "MS-DOS FAT32" STICK_NAME MBR /dev/diskX
