The VideoLAN Forums

OK let me explain a little better -- I am using VLC Media Player 0.9.8a Grishenko in Windows XP SP 3. In the past (using 0.8 builds) I have been able to transcode/convert any YouTube streams (which are usually of the FLV flavor) into OGG container MPEGs, but since updating, it appears as though the MUX/DEMUX process has broken for FLVs. Now when I use my "custom" settings: Container = OGG, Video = MPEG-4, Audio = MPEG Audio, I get an empty file as a result. When I use the now default "OGG / Vorbis" settings, I get an empty file, and when I use the now default "OGG / Theora" settings I get video, but no audio. Can somebody explain either what I'm doing wrong, or what's broken, and where I can learn about what's being done?

Thanks.

Open Tools -> Messages... (set Verbosity to 2) before doing any transcoding and paste messages here after you have tried to transcode.

Here we go...This was using the default "Ogg/Vorbis" settings:

You only have problems with googlevideo.com content?

I second this.

From at least 0.9.6 , it's impossible to encode in vorbis. ""stream_out_transcode error: cannot find audio encoder (module:any fourcc:vorb)""

I guess it's just a module missing ?

It's really blocker as VLC is a good solution for encoding Ogg/theora video for the upcoming Firefox 3.1 .

I encoded in Speex for now but firefox and cortado won't support it.

VLC for windows? Really ?
I need more messages for that.

At least my 0.9.8a creates working OGG files which have vorbis audio inside them (using Profile Ogg / Vorbis).

I downgraded to 0.8.6i and am once again able to re-encode FLVs into OGG container with MP4 video and MPG Audio (granted the first few frames are covered with green sludge, but it's better than the 0.9.x series)

btw: I have these errors whenever I try to encode google video or anything that turns out to be an FLV. I even tried to download the FLV and perform a local convert, but it resulted in the same 0 bytes OGG file.

MegaVideo doesn't encode either. I don't know what the expiration on these is, but try for example this one: http://www492.megavideo.com/files/f8390 ... a6dcd29f0/

That megavideo link is expired.
