File size control in CQP mode #165
Description
Hi, I'm speaking as the author of https://github.com/brauliobo/media-downloader-bot
I need to ensure the file size isn't bigger than Telegram 50mb limit for bot uploads.
I'm using the CQP setting there to provide a consistent quality.
In H264 I can provide a buffer size of 50M and restrict the max rate while using -crf option in FFMpeg (see https://github.com/brauliobo/media-downloader-bot/blob/main/zipper.rb#L33)
How can I do something similar with SVT-VP9?

If you know the video duration in advance you can calculate the maximum bitrate in order for the resulting file not to exceed 50 MB.
Let's suppose the duration is 100 seconds:
The command would be:
Please note that the resulting file size is not determined by the video track(s) alone. Audio track(s) and the container itself should be taken into account.
