#1496 open enhancement

Stream passthru : VideoCodec copy

Description

FFserver does not support FFmpeg's "-vcodec copy" or "-acodec copy"
VideoCodec? copy
AudioCodec? copy

1) "-vcodec/-acodec copy" is very useful when you just want to change the container of the stream

2) If you have output streams at various bitrates: high(same as input feed), low;
then only the low quality stream would need to be re-encoded saving cpu time.

Is there any activity on this feature?

Would it be difficult to implement it?
I have a use case where prevention of transcoding is a requirement, so I'd like to see it implemented soon.

For some reason, ffserver 2.4 actually supported this if you didn't configure the codec in ffserver.conf. In newer versions, transcoding seems to be enforced, and with very low default settings if you don't specify any.

ffserver is essentialy unmaintained.
If you send patches they'd most likely be happily accepted, but I think it's unlikely anyone will pick up ffserver anytime soon.

Too bad.

But I'll give it a shot.
Can't be too hard, right? :)
