Transcode existing stream to lower quality

Postby hevilp » 19 Mar 2016 11:46

Hello,

I got a http-stream:
Video Codec
H264 - MPEG-4 AVC (part10) (h264)
Resolution 1920x1090
fps: 25
decoded format: Planar 4:2:0 YUV

Audio Codec:
A52 Audio aka AC
Bitrate 384

I want to transcode to another http-stream with better compression.

Code: Select all

I tried: vlc -vvv http://192.168.178.37:31339 --sout '#transcode{acodec=a52,ab=128}:standard{access=http,mux=ts,dst=:8080}'
With vcodec=H263 and h265 I get Audio to destiny, but no video.

With h264 a get:

Code: Select all

How I can transcode it to a http stream for lower bandwith?
thanks
