<DIV><FONT face=Arial size=2>Hi Folks,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>First, I would like to thank the eople in
development who are doing so much to develope these great video and audio
tools.</FONT></DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've tried for the first time to encode an AVI file
from my digital camera to .ogv using ffmpeg2theora.</FONT></DIV>
<DIV><FONT face=Arial size=2>I came across a few potential bugs.</FONT></DIV>
<DIV><FONT face=Arial size=2>First, if changing the speedlevel parameter to 0 or
using the Optimize parameter, and an output file is not specified, the encoder
does not automatically assume the same input Filename.avi to output
Filename.ogv.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, in order to playback using Winamp, I
installed the Ogg Codec from the download page, and added the .ogv extension to
Winamp's Directshow input plugin's extension list.</FONT></DIV>
<DIV><FONT face=Arial size=2>The playback of the files, whether or not I play
them in Mediaplayer, Winamp or another player, produces a very distorted audio
playback, which sounds more like audio distortion of chipmunks through an
overdrive guitar filter, (for lack of a better description).</FONT></DIV>
<DIV><FONT face=Arial size=2>The video is upsidedown in Winamp but looks correct
in Mediaplayer.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Back to the audio, I'm not sure if the audio
problem exists because my digital camera produces audio at 11025 Hz, 8 bps,
Mono (that's according to Winamp's info reported by the Directshow
stream).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>To keep things simple, I encoded with ffmpeg2theora
without using any -switches or parameters. It was a .avi video of my 3-month old
son being bathed and splashing in the water.</FONT></DIV>
<DIV><FONT face=Arial size=2>Here's the very basic syntax I've
used:</FONT></DIV>
<DIV><FONT face=Arial size=2>ffmpeg2theora Baby.avi</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does anyone have any solutions to identifying why I
am getting these strange results? How much of it could have to do with the
ffmpeg2theora encoder and how much to do with the Directshow
decoder ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm more than ready to send the .AVI file to
someone for testing, though it may be quite large, around 160 Mb.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>One last question: What do I do if I want to create
a straight .ogv file out of a DVD video, wherein there is the Audio_ts and
Video_ts folders? You know, from regular DVD Videos.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for any advice in advance.</FONT></DIV>
<DIV><FONT face=Arial size=2>Kind regards,</FONT></DIV>
