can't demux with ogminfo / need to re-pac OGV to MKV
Hello,
I need to demux video files created with ffmpeg2theora 0.28+svn18147
I have ogminfo v1.5
and getting this error
(ogminfo.c) OGG stream 1 is of an unknown type (bad header?)
(ogminfo.c) OGG stream 2 is of an unknown type (bad header?)
(ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000)
Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

Ogv file only plays in VLC / Can't be used by most tools.
Hi,
I'm new here - thanks for having me. (Sorry if I'm in the wrong place or a noob.)
I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a sequence of bitmaps, and created an OGV file.
The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else with it:
I tried uploading to YouTube, and the video just comes out really corrupt:

metadata (like title) in OGV?
Hi,
I'm trying to add Title and other metadata to OGV, when encoding with ffmpeg2theora 0.24.
Unfortunatelly, mplayer and VLC is not showing any metadata.
Shall this work with ffmpeg2theora 0.24?
Exist something like vorbiscomment to check / do it with
OGG/Vorbig/Theora?
Thank you,
Jiri

Saw an OGV/Ffmpeg player for Iphone , can you test?
hello , I m' not sure there are a lot of Ipad/iphone owners but maybe some
of you can confirm that this GPL/3$ app can :
- play ogv theora files downloaded from the Web with Safari?
- Play in a browser via <video> ( I doubt ...)

ffmpeg2theora bug: generation of a video from a series of images
Hi J.,
We are using ffmpeg2theora to produce an introduction video from a
series of images:
ffmpeg2theora-0.26.linux32.bin images/img-%03d.png -o intro.ogv
The video that we get is huge and horrible, with lots of blinking colors:

Thank you,

Differentiating Video from Audio
I am trying to write a "thumbnailer" for the thunar file manager that
can process .ogg files containing a video stream and produce a thumbnail
of a particular frame. The only trouble is telling which files have a
video stream in an efficient method. The best I've come up with is
running ogginfo on every file with the mimetype application/ogg.
Is there a better method?

python bindings to libtheora
Hi,
in the past two days I wrote Python bindings to libtheora:

Currently it can read any ogv file (that seems to work quite well) and
also encode to ogv (this mostly works, but there are some subtle
issues to be fixed, I suspect I still have some bug in the way I half

Bad results, encoding keynote presentation videos
Hello,
hope you can help me. I want to encode a video, which I have exported
from Keynote (a program for presentation like MS Power Point) using
ffmpeg2theora for html5 web delivery.
The result only plays very buggy - frames are dropped, the video hangs
and vlc can not output the correct length of the ogv video.
Here is the source and the result for download, if you want to reproduce it:

Further bug discovered with the Directshow decoder
Hi good people,
Just to inform:
I finally fed FFMpeg2Theora with a .VOB input, and the .OGV output produced played back beautifully in VLC, both audio and video. However, the same output .OGV file gave clicks and pops in the audio when fed through Directshow programs. I played it through Windows Mediaplayer as well as through Winamp, with the same crackles in the audio, and this leads me to

Add an intro to a theora file without re-encoding?
Hello,
I would like to add a introduction video (typically a title with fade-in
/ fade-out) at the beginning of an Ogg/Theora video. I generated this
intro video in Ogg/Theora from a sequence of png files.
I would need to do this in an automatic script, because I have many such
videos to process, and without doing any re-encoding step (which would
be very costly because my videos are huge).

oggz-merge.exe

Fwd: Vorbis-java wav-ogg encoder produces distorted OGG file
Hi,
I was really interested in the java version of the same since I wanted to

Anybody who have managed to use the java port to encode wav to ogg, this is
only audio, can assist me to solve my problem. I have been looking at the
code and the svn but no updates seem to be available. Some guidance on what

Live webcam stream with Theora
Hey all,
I've setup a simple page that just displays a live webcam stream of me
at work, and it supposedly falls back onto Cortado if your browser
doesn't support the <video> tag. The URL is here:

There's been a lot of talk about live streaming and low bitrate
streams. Here is my command line (I've posted this before):
