## Get englisgh transcripts of a tree of .mp4 files
## Cost incurred: 200 videos of ~3 minutes each => around ~$5
## Other params: ~200 API calls; total ~40,000 seconds
## Cost estimate as per pricing chart: 683 min * 0.006 = ~4.098
## Ignores non mp4 files
## Adds .mp3 files for each file, and then calls Whisper API and stores the .txt
## Nothing is deleted
## Resumable

VLC Playlist (XSPF) generator from file tree

Why

I had some videos (actually a folder that one more level of folders and finally video files).

I wanted to generate .xspf files for the whole folder, where each subfolder became a playlist. i.e I wanted to generate multiple files (one corresponding to each folder) XSPF files are used by VLC to store a string of videos. You can open the file with VLC and it will play them as a playlist, allowing prev/next video.

How to use

  • tree.js is used for generating the tree structure of the root folder, as an object.

Gnome Terminal (the default Ubuntu terminal) tips, quirks

Open a new terminal at given directory

gnome-terminal --working-directory some_path

Note:

  1. this option works only if used before other options, so keep it before.
  2. It doesn't work with relative paths, i.e. .. won't work. This could be solved - StackOverflow

Open a new terminal (as a tab)

📱React Native setup, ADB wirless

Steps (to set up an existing React Native app)

  1. Install react-native-cli globally, by running npm install -g react-native-cli.
  2. Clone the repo. Do npm install inside it.
  3. Connect phone (real) to the computer - by enabling USB debgugging/Wirelsss debugging through the "Developer Options" ((may need to enable them first, by clicking "Build number" repeatedly)). Accept permissions.
  4. Make sure the phone connected by running adb devices in the terminal. A device should be added, in the success case.
  5. Run react-native start, press "a" for Android.
  6. "r" when the procees seems to have stopped. Keep pressing this if something gets stuck.
  7. The app should now be installed and running on the phone.
  8. Editing files should update the app now, automatically
