We default to `.mkv` for the output container. If you prefer something else (like `mp4`), pass `--format mp4`.
Download a video -
```sh
$ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1"
```
Download a video and re-encode with HEVC (libx265):
```sh
$ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" --vcodec libx265
```
Download a video and speed up the interactive login by automagically filling in the username -
```sh
$ ./destreamer.sh -u user@example.com -i "https://web.microsoftstream.com/video/VIDEO-1"
