The VideoLAN Forums

I have sucessfully used VLC 8.6, 9.8a, and 9.9 to stream via http using capture card to lan/wan via website

No longer seems to work with current RC1

Capture device displays/plays on own OK

For Streaming...

I use Win wmv/asf and pick up the stream with a .asx metafile. I have usually left the http address field Blank so the stream is accessable from lan and wan IPs. via web, MS Media Player, Kaffeine, etc
I can get a local display with the Transcode box left Unchecked
With Transcode box checked, VLC locks and local display stops, no stream

Is this a known issue?

Shall I post back more info/feedback?

Yes, please, more info.

Bit more background first
I use VLC amongt other streamers (including..WM Encoder, Star media centre, Media Master) to stream to website.
I use the windows WMV- asf format because at this time it is universally readable by many of the main browsers and media players as well as VLC
I use both MS Windows and Linux (currently Ubuntu and Mandriva)
To date VLC works well (if a little slow) in all cases, often on quite low specification boxes Eg circa 1GHz cpu and 500MB ram
I appreciate I am on (perhaps now past?) the limit of box capability, but the test box did run OK(ish) with VLC 9.8a and the other windows streamers using WMV/asf and quite well using H264 with VLC as both client and server.

I will not have a heigher spec Win XP box available to try it on for a few weeks

Info in more detail as follows.

Streaming settings (2)

All settings as per (1) above except Play locally box checked
Result
Sometime a poor local display, sometimes locked in corrupted single frame

Message box
No suitable decoder module:
VLC does not support the audio or video format "wma ". Unfortunately there is no way for you to fix this.


Is it a bug, or have I made a settings mistake? Is there a minimum hardware requirement for VLC 1.0.0?

Any other info required?

Can you give more messages?

I have just done a re run with previous settings
Play locally box checked

Result

Local display heavily blocked and stalled

want me to try something else?

I have tried again using VLC 1.0.0 RC2 in the above setup

reduced frame size to 320x240 to reduce cpu load
left default setting of 0.0.0.0 in address field

Much the same results, although local display did not freeze/stall.
But.
Failed to stream http wma/asf.

VLC still reports that it is unable to support wma???

message reports as follows...........

Comments?

acodec WMA2

Solved, thankyou.

Re above issue. I have just tried the RC3

VLC still defaults to acodec=wma (which it error reports that does not currently support) and has to be manually changed to wma2 to stream.

Is this still a bug?
or
Is there a reason for this default by design?

It is a bug. It will be fixed in release.
