Transcoding a video stream for http

Postby JK010 » 21 Nov 2017 04:41

I'm wondering what the best options are for transcoding a video stream (with no audio) via VLC command line, and then for playing it in JWPlayer (or any other JS HTML player)?

I've been testing it with quite a few options (that I've found in the docs and on this forum) but I can't seem to get the video to play in VLC Player (in the first instance), before I try to display it in the HTML.

When I use: .\vlc -I dummy -vvv stream_input_url --”sout=#transcode{vcodec=h264,acodec=none}:standard{mux=mp4,dst=:8081/c.mp4,access=http}”

the transcoder and streamer starts to run, but after a few seconds the window crashes and closes.

Then when I use the following example (different vcodec):
.\vlc -I dummy -vvv stream_input_url --”sout=#transcode{vcodec=FLV1,acodec=none}:standard{mux=mp4,dst=:8081/c.mp4,access=http}”

The transcoder and streamer runs successfully, I get the following error log in VLC Player:

I just want to check which vcodec option I should be using (or which would be best for what I'm trying to do) and if any of my settings look incorrect, or if there is any other settings that I should be looking at?
