termux-vid-compression

Issue

Currently my phone records videos in a very high quality resulting into very large files. Those files get currently automatically synced with my OwnCloud. I'd rather have them in a compressed version available. This also makes streaming from the cloud more easy.

Supported Features

• Script to convert all videos in a folder into compressed versions in another folder
• webdav sync to transfer all files in own folder into a webdav location. Only files with changes file sizes are transmitted. No nested transmission.
• webdav-sync-hook, which allows for termux to accept shared files and transfer them to your configured $WEBDAV_URL-server. The hook will let you first rename your file and then browse via cadaver to your target location of choice. Afterwards run put <my-renamed-file> to transfer it.

Installation

• mkdir -p $HOME/.local/lib 
  git clone https://github.com/LuzianHahn/termux-vid-compression.git $HOME/.local/lib/termux-vid-compression
  bash $HOME/.local/lib/termux-vid-compression/installer.sh

• You need the following packages: cadaver, ffmpeg
• In order to use the shortcuts, configure a local .env file in this repository with:

  $VIDEO_SRC        # used as source directory for large videos, you want to compress
  $VIDEO_TRG        # used as target directory to store the compressed videos from $VIDEO_SRC
  $VIDEO_LOCAL_SRC  # used as local source directory to sync videos from
  $VIDEO_REMOTE_TRG # used as remote target directory on a webdav server to sync your videos to
  $WEBDAV_URL       # url for your webdav service, to which the videos are synced to

• Configure a $HOME/.netrc file to authenticate yourself against your webdav service. See also https://man.archlinux.org/man/cadaver.1.en#THE_.netrc_FILE

Backup-Cronjob

• calling bash installer.sh already sets up a cronjob for this. However, it is necessary to configure a .env.bakbak-file in the root of this repo, which contains:

  $LOCAL_SRC  # used as local source directory to sync backups from
  $REMOTE_TRG # used as remote target directory on a webdav server to sync your backups to
  $WEBDAV_URL       # url for your webdav service, to which the backups are synced to 

Potential solution

• get script for compression running on phone via termux
• use two folders, one for storing the original videos, second for storing the compressed versions
• use cadaver to sync with webdav owncloud
• use cronjobs on the phone to do this regularly
• refactor this using rust, to practice it and avoid complex bash scripts. Also allows for better testing

Ideas

• use find instead of for loop, in case of no content raising in error ($SRC_DIR/* is then interpreted as file)
• consider clean up on the phone. Currently not necessary, since I have a lot of storage. I can also buy a large micro SD card to hold them instead. However since termux cannot access the SD-Card, this would require a more complicated solution
• use different compression approaches to even further compress videos
• add compression for images

Development

The test are done via python, although the utilities don't use it. In order to run the tests, you need to install pytest and run
