Staxrip: NVENC and QSVENS Subtitles file option must be removed

[ghost]

Describe the bug
The option Other > Subtitle File must be removed from :

• NVEnc : h264, h265
• QSVEnc : h264, h265

because this options allows to mux (not harcode!) a subtitle file to the output of NVEnc and QSVEnc. Since in Staxrip the output of the encoder is *.h264 or *.h265, this option makes crash.

You've got a point.

The console help is not enough for this option --sub-source. In online help, it's about _muxing_ an external subtitle file.

Read subtitle from the specified file and _mux_ into the output file.

Since all we need is the encoded video elementary stream, this option is useless for us.

And also it leads to a crash !

In online help, it's about muxing an external subtitle file.

I also had confirmation from Rigaya https://github.com/rigaya/NVEnc/issues/311

You're right. ES cannot contain subtitle streams. And subtitle hard-burning is available only via --vpp-subburn.

BTW, @Dendraspis and I once agreed that in NVEnc, _online_ help is a must. (Console help is often wrong and insufficient.) 😆
