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:

ffmpeg2theora: issue converting from a png image list
Hi Jan, all
I am trying to generate a video introduction with a fade-in / fade-out
effect. To do this with ffmpeg2theora only, I generated a list of PNG
images: img001.png, img002.png... img299.png
The ffmpeg2theora man page says:
Encode a series of images:
ffmpeg2theora frame%06d.png -o output.ogv
That's exactly what I tried with the latest 0.24 release of ffmpeg2theora:

ffmpeg2theora 0.24 regression: accelerated video output (converted from h264)
Here's another problem I have with the 0.24 version of ffmpeg2theora.
When I try to convert a h264 file to theora...
(Note that for size and runtime reasons, foo.mts is a truncated file,
I just took the first 32MB of the original file)

Strange results encoding with latest ffmpeg2theora-0.24 and playback on Directshow through Winamp
Hi Folks,
First, I would like to thank the eople in development who are doing so much to develope these great video and audio tools.
I use Ogg Vorbis to store most of my music projects in studio and the results are stunning. Quite frankly, in the audio file reduction game, nothing beats Ogg Vorbis and I can personally say this from my own experience. So a huge thank you to the team.

ffmpeg2theora 0.25 synchronization issues when converting from .mov
Has anyone noticed this? I have a video made with Final Cut Pro,
which I convert to .mov via Compressor. This .mov file plays back
fine in Quicktime. But when I then use ffmpeg2theora to convert to
ogv, the video seems to play back too fast compared to the audio (I'm
using VLC 1.0.2, the latest I believe, to play back the ogv file, and
I also have an app that uses the recently

Ogg is great!! Tools: ffmpeg2theora, oggz
Hi, I just wanted to say that I've recently become a fan off the ogg movie format. I haven't really done much with video before, but I recently got a Canon DSLR which can record HD movies at 30 fps, 720p. The resulting files are great, but too large to share over the web.
After trying a few different encoding tools, I quickly found that ffmpeg2theora is super easy to use, gives good

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:

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?

Bad memory access in libtheora beta3
Hi,
I didn't get to the bottom of it, but Valgrind is whining
on libtheora when encoding a video to a 16 width or
16 height video. While you may think I'm weird for
encoding to such a size, I didn't care about the output
video, but I reckon it should work. The bad accesses
seemed to be of pixel data, in FilterVert__c, and in
FilterHorz__c (from memory), but I didn't investigate

ffmpeg2theora tool
I've been encoding with ffmpeg.exe. Due to the muxing issue, I tried
ffmpeg2theora, but I ran into some issues
1. it fails on 1080p content. 1920x1080. 1920x800 is okay.
2. I have raw yuv. in ffmpeg I use -s 1920x1080 to specify the source
size. ffmpeg2theora doesnt seem to have a way to accept width/height
for the raw yuv (420). So I need to do an additional step of muxing
it into a

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
