No stream output for VP8

[vbence]

Currently only file output is usable with VP8. I know that the specifications for VP8 over RTP and such things are work in progress, but it would be nice if VLC could offer ANY (if even yet VLC-only) options to send out VP8 encoded stream from the computer.

As far as I checked the MKV muxer supports VP8 (as WebM is basically MKV too), but none of the stream output methods (http, rtp, udp etc.) support MKV, so this is a dead end too. As strange as it sounds even RAW output refuses to handle VP8.

So... as a feature request: it would be nice if a VP8 stream could leave my computer in some way other than SMB-ing it to the server.

Thanks!

MKV over HTTP should work just fine. Of course, you would not use VLC to SEND the stream, just a standard web server.

That's correct, but if I use "file" fileoutput I loose the real-time aspect. All the other network-centric outputs have the possibility to send a live stream, but currently none of them works with MKV (or WebM), and the other muxers do not work with VP8.

I don't think you need use to output a MKV file, it seems completely plausible to send out the stream in real-time.

webm muxer of VLC is untested.

Hi,
sorry for the bad english
i am using UDP as my transport protocol. i have encoded the vp8 codec using ffmpeg.

the command line i have used for converting the raw video into VP8 is ffmpeg -v 8 -i /home/yesshwannt/ffmpeg/doc/project/foreman_cif.y4m -vcodec libvpx -vb 768k -f webm out989.webm

i have downloaded the y4u video from with cif from http://media.xiph.org/video/derf/

My problem is i cannot stream the video which i have encoded using FFmpeg in vlc from one system to another. can you please answer and help me out in this case

i have taken the profile as vp80+vorbis(webm)

for the encapsulation i have used webm.

for the video codec i have taken VP8

with bit rate 700kbps
and frame rate 20 fps
scale 1
width 0
height 0

Audio codec NA

in the client side i have used udp://@:1234

best regards
yesshwannt

@indianprinceb9: The MKV muxer only support FILE output, no UDP, no HTTP no anything. Except FILE. I already told this in my first post. Please try to read thethread before posting.

Yes, fixing it might be welcome though...

The VLC muxer abstraction does not support live streaming with any format other than TS. In theory, it could be fixed, but this would be quite invovled.
