Before you download, there were two separated programs:
AndroidUVG266.7z - 10-bit input/encoder only.
AndroidUVG266-8bit.7z - 8-bit input/encoder only.
If you want pipe from FFmpeg to uvg266, you can do command:
```
ffmpeg -i example.mp4 -f yuv4mpegpipe -pix_fmt yuv420p10 -strict -1 - | uvg266 -i - --input-file-format y4m --input-bitdepth 10 -o converted.266
```
For 8-bit uvg266 application, remove `-strict -1`, change from `yuv420p10` to `yuv420p` and remove `--input-bitdepth-10`.

When you want make device sleep during uvg266 encoding, tap Acquire wake lock on Termux notification.

If uvg266 froze itself for a couple minutes without printing info, means finished, tap CTRL + C.

VVDEC might not decode with some uvg266 options (example uvg266 presets unplayable with vvdec: preset placebo & lossless.
