Hi I would like to know if it's possible to convert a video (avi, mpeg, wmv...) to FLV format using VLC.
Thanks

It isn't. In fact i don't think that any open source FLV encoder exists.

FFmpeg can encode to Sorenson (NOT VP6) FLV.

Oh ... i though you meant VP6

Well you can find the soreson fourcc in http://trac.videolan.org/vlc/browser/tr ... g/ffmpeg.c (seems to be SVQ1 and SVQ3 and use that in the vcodec transcode option). Use "flv" for the mux.

Btw, the flv muxing won't work in 0.8.5. I doubt that it will in 0.8.6-test1 (it's worth a try though) and it'll definitively work if you try a 0.9.0 nightly.

What kind of access module do I need to use for FLV streaming:

--sout '#transcode{vcodec=SVQ1,vb=256,scale=1,acodec=mp3,ab=32,channels=2}:std{access=http,mux=flv,dst=:8888}'

with version 0.9.0-svn-20061018-1453

I can use vcodec=SVQ1, but if I put the mux=flv then I get the following message:

main error: no sout mux module matched "flv"
stream_out_standard error: no suitable sout mux module for `file/flv://c:\out.flv'

Where can I find the flv mux module?

I am also very interested in the FLV approach. Is it working now?

And how can I install the plugin (?) from http://trac.videolan.org/vlc/browser/tr ... g/ffmpeg.c into VideoLan?

I also get:
What to do about this?

Anyone got FLV streaming to work?

I don't think it is doable yet. It should not be very hard to make but VLC does not use ffmpeg libavformat. And flv muxing seems not to have been reimplemented in VLC.

I may mistake on that issue still.

Also in version 0.9?

with version 0.9.0-svn-20061018-1453

I can use vcodec=SVQ1, but if I put the mux=flv then I get the following message:

main error: no sout mux module matched "flv"
stream_out_standard error: no suitable sout mux module for `file/flv://c:\out.flv'

Where can I find the flv mux module?

what about mux=h263

or mux=flv1

Hi , when i transcode a wmv netstream in FLV (works fine for the video stream) i have a probleme with sound for mp3 transcoding(no input for audio)
An idea?
best regards.

i got it, it was a missconfiguration thing !

hi,

first of all, thank you for this nice feature to stream in flv format. it such a cool feature i only found in videolan. except that building 0.9.0 took the whole night on my kubuntu machine and with qt4 missing gui seems buggy, cant open any source file, always getting no access module. duno why, but not necessary anyway for the task i want to perform.

nevertheless streaming works pretty well, just one thing doesnt want to work the way i want it to be.

i encode a dvb-t stream with the following command
when i try to read this stream with vlc again, it gives me
back and so on, just plaing sound after a while. in the streaming instance of vlc it looks fine for me
but perhaps this one is indicating the problem
without the size parametere it streams the file properly and the client can read it.
so is resizing and cropping not implemented yet in the newest version of VLC media player 0.9.0-svn Grishenko for flv streaming or is it my command?

if its not my fault, i would be really thankful if this feature could be implemented in the near future then

furthermore, is it possible to write that flv stream to a pipe while its streaming over http? any example code would be nice.

so thanks for your help.

solved the issue. seems like my problem was related to

Ticket #1043
missing video filters: corrupt transcode and no screenshot support

i had ffmpeg compiled with --enable-swscaler, so no working cropping.
now i recompiled newest ffmpeg without it and it works.

now i am happy and good night everybody

Well, I'm trying to get this to work as well, using vlc-0.9.0 and ffmpeg 20070329 cvs.

I'm guessing that its something in the compiling (or actually configure options) as at the moment, its not likeing the mux=ffmpeg{mux=flv} option, and I'm getting all sorts of other errors and warnings when running vlc.

So could anyone who has this working please post their configure line for vlc as well as ffmpeg.

ffmpeg: and vlc: anyone see anything that should be added? basically, I want to be able to deal with anything thats thrown at me. Current project is to take a live stream from my axis 214 camera and transcode to flv.

I almost said the heck with it, and was going to purchase flash media server, but $4,500 for a novelty function is a little obsurd.

if you were frustrated enough, you could always go the:
Upload to U-toob, then just use the realplayer downloader and store them, or snag the .flv files from your temp directories ... i believe that there are several different sites that actually function as an upload/convert/then give you a link to download it again.

Seems like alot of hassle though, especially if you are doing any kind of an amount of files. VLC works so slick in what it already does, that I can hardly wait for it to be capable of doing both to and from flv's.

It seems that FLV is supported as input:

now, though I haven't tried it personally...
