trying to understand the transcoding plugins and how they work

[Hojojo]

i noticed that FFmpeg doesn't transcode( encode) , it actually act as if its an invisible player that ports the video (stream) it to the wanted display ,
but not remuxing nor No trans-coding , it acts as if its a player is that true ?
i actually like this but want to confirm that this is the case , and its not trans-coding, how i can confirm while the video is playing , that such stream is not a transcode(encode)?
is it possible that the video gets streamed untouched , while the audio gets transcoded ?

last question.
some video files gets its audio late than the video.

I am not expert, but I think ffmpeg does transcoding. When I look at debug.log, I can see that ffmpeg is executing while video is streaming. I can also see parameters given ffmpeg. For example,

Code: Select all

-c:v libx264

, my video is transcoding from whatever the original file is to 264 and confirm using media codec info in VLC.

To get the stream untouch, you can edit renderer config. Under support section, I believe if support section match the existing format, then, it will stream as is.
