# Android vvdec/uvg266 applications (Termux app)

Requirements: Termux app with apk or F-Droid app. For uvg266/vvdecapp pipe, require FFmpeg on Termux app.

See the screenshot of vvdecapp in Termux app:

All system types of arm64, armeabi, x86 and x86_64 are built on vvdecapp & uvg266, it is use of Termux app.

arm64 - API 21 (64-bit phones only)

armeabi - API 19 (32-bit phones)

x86 & x86_64 - API 21 (tablets only)

TIP: You can install my built applications:

```
chmod +x vvdecapp uvg266
cp vvdecapp uvg266 $PREFIX/bin
```

### uvg266 encoder

Before you download, there were two seperated 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 wakelock on Termux notification.

If uvg266 froze itself than an couple minutes without printing info, means finished CTRL + C.

VVDEC might not decode with some uvg266 options (example uvg266 presets unplayable with vvdec: ultrafast, superfast, veryfast, veryslow, placebo).
