Docker container to transcode videos in mounted volume to H265
- Change the volume to point at your root media folder
docker-compose up -d
docker logs transcoder_transcoder_1 && docker attach --no-stdin transcoder_transcoder_1
(CTRL-C is safe to exit with)
- Create a .env file
- Set
BOT_KEYandCHAT_IDvariables - Recreate the container
You can ignore files using .transcodeignore, which will make it not transcode any files in that directory or subdirectories.
By default, the option to re-transcode H265 -> H265 is enabled. You can turn it off by setting environment variable H265_TRANSCODE to False
The other variable H265_MB_H defines how many MB/h is your target. If a file is below that target, it will not attempt to re-transcode the file.
It uses the formula size / duration instead of the reported bit rate by ffmpeg, as it seems it is often incorrect and not representative of the resulting file size.
