+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 -o converted.266
+```
+
+For 8-bit uvg266 application, remove `-strict -1` and change from `yuv420p10` to `yuv420p`.
+
+When you want make device sleep during uvg266 encoding, tap Acquire wakelock on Termux notification.
+
+VVDEC might not decode with some uvg266 options (example uvg266 presets unplayable with vvdec: ultrafast, superfast, veryfast, veryslow, placebo).
