convert audio stream only, copy video stream?

[The4Apes]

Copy audio and sub is possible with "--audio-copy" and "--sub-copy", but i cant find a copy option for video stream. How can i copy the video stream?

NVEnc is developed fro video encoding, there is no feature to copy video stream.

Many other programs for video encoding feature copy video stream. A function for copying the video stream would not be a contradiction. But if that is not desired, I did it differently now. I used NVEnc to recoded the video and audio stream and MKVToolNix to merged the original video stream with the recoded audio stream . Works too.

You can copy the video and only encode the audio to another format using FFmpeg.

Copying the Video Stream: FFmpeg can copy a video stream without re-encoding it using the -c:v copy parameter. This means the video quality and characteristics will remain unchanged, and the process will be faster as it avoids re-encoding.

Re-encoding Audio: To re-encode the audio stream, perhaps to a different format or specifications, FFmpeg can do this with various audio codecs. For example, using -c:a libmp3lame to encode audio into MP3 format.

Merging Streams: FFmpeg can also mux the video and audio streams into various container formats like MKV, MP4, etc., effectively combining the original video stream with a newly encoded audio stream.

I’m sorry but there is no plan to support video copy feature, so I’ll have this issue closed.
