Tools for VMS

[Rl0007]

• A new tools tab in the sidebar
• Tabs for each tool (there will be only one tool to start with "Compress") use https://ui.shadcn.com/docs/components/base/tabs
• User sees an area/button to upload their file (maybe reuse the upload dialog in a different context)
• Once uploaded, show progress of compression using background jobs + socket I/O (check frappe react sdk + publish_realtime) (https://ui.shadcn.com/docs/components/base/progress)
• After it finishes show area with download option and details like how much percent reduction etc.

• no need to save the raw footage just compress and download maybe keep it for 3 - 7 days give a setting for it, in Frappe backend only

Technical details:

ffmpeg -i input.mov \
  -c:v libx264 -preset medium -crf 23 -pix_fmt yuv420p \
  -c:a aac -b:a 160k \
  -movflags +faststart \
  output.mp4

Cap resolution: -vf "scale='min(1920,iw)':-2"

“Smart” mode (fast remux when possible, else transcode)

Sometimes your .mkv already contains H.264 + AAC and you don’t need recompression—just repackage to MP4:

ffmpeg -i input.mkv -c copy -movflags +faststart output.mp4

This only works if codecs are MP4-compatible (e.g., H.264/H.265 video + AAC audio).
