When transcoding file(s) with multiple streams (for example multilanguage subtitles) NVEnc sets all as DEFAULT

[jeryll7]

NVEnc should copy DEFAULT attributes from source to destination, sure, this may look as triviality, but for example ffmpeg can copy DEFAULT stream attribute correctly.

This is easily reproducible, just use media file with multiple subtitle stream included, check with mediainfo for how the DEFAULT attribute is set, transcode file with NVEnc with --sub-copy option, then check result file with mediainfo - all subtitle streams will have DEFAULT attribute set.

I have added code to copy attributes of streams (audio & subtitles) in NVEnc 3.29.

OK, thanks, I can confirm that NVEnc 3.29 correctly copies audio and subtitles streams default attributes, but unfortunately now VIDEO stream DEFAULT attribute (if set) is not copied (also VIDEO stream LANGUAGE attribute is not copied - is missing in result file).
Should I close this and open a new issue?

OK, NVEnc 3.30 will copy attribute of video when possible (for avhw/avsw reader).

Ok, thanks, NVEnc 3.30 now copies stream(s) attributes correctly.
