vlc video codec VP70

[David D.]

I was doing some searches on this subject and one of the links was to the Ask VideoLan site. The person making the query was asking VideoLan to include the VP7 codec in VLC. The response was to "ask Google to make it open-source".

Despite Google's lack of action VP7 decoding has recently been reverse engineered by FFmpeg without their help.

.

Have you been able to get audio on that one?

Remember when Google used to be the good guys?

Almost . FFmpeg now has an On2 avc decoder which fails with this sample but soon perhaps...

Also in MPlayer:

Add decoding support for On2 AVC audio codec.

which is compiling as I type

For MS Windows Operating Systems:

VP7 or VP70 is a compressed video data created by On2 Technologies Inc. Further details about this can be found in the link below.

You can play this type of file by downloading and installing following audio/video codec pack:

http://www.mediafire.com/download/u919ueuakmbiclw/Audio_Codec_Pack_-_VP70.exe

This solve the Windows Media Player error C00D10D1: On2 VP70 (VP70) or Missing codec: On2 VP70 (VP70) error.
These play file in Windows Media Player only after installing codec pack above.

I hope it helps. Thanks for reading and plz like.

Looks like some good news is here:

On2 VP7 decoder
http://git.videolan.org/?p=ffmpeg.gi...d46093a01a4135

and on my system:

andrew@ilium~$ ffmpeg -codecs 2>/dev/null | grep -i vp7
 D.V.L. vp7                  On2 VP7

and ffplay plays this file (sound and video) on my 64bit system

Running 14.04.2
OK, when I type that command in terminal I get the same output. But what Am I supposed to do with that git ink? I read in an article that ffmpeg AND vlc 2.2 support on2 and VP7. I tried upgrading to VLC 3 and i ending up hosing my system with broken packages. So I'm back to VLC 2.2.1 but all i get is audio. Normally it wouldn't be a big thing but I just found all six seasons of chips and of course the guy who encoded it used an obscure codec that Google owns now. Mplayer/smplayer is supposed to support it to, but this is what I get when I try that:

vlc that use libav9 cannot decode vp7, you'll need a vlc that uses either libav11 or ffmpeg. Also note that vlc cannot decode vp7 audio though not all vp7 vids uses vp7 audio. (- yours seem to use something else.

As far as mplayer you are using mplayer2 with libav9, not going to work.

(- where did you get vlc from?
