[theora] Windows Software for Theora - was: QTheoraFrontend & MACRO BLOCKS PROBLEM ON CONVERTED OGG FILE
hi yorn and all,
thank you oggvideo tools for windows. it is great... i can live with the command
line for now myself but i will need to make some art students work with
oggvideotools and they may not be happy with that:D anyway your video tutorial
is also good (but it also crashed my firefox 3.5 beta 4 for two times on windows
and i have reported that to mozilla), i would love to help for that as you
offered in your previous mail but i am just new into oggvideotools and not a
tech person, so maybe i can help for video tutorials when i have more
experince... but i am planning to write a very simple dummy's tutorial for
the students just for oggcat on windows to concatenate some videos we are
working on...
anyway, oggcat works great for me on windows! but there is one issue i should
let you know about the Skeleton...
oggcat works totally ok on windows for the ogg files created with ffmpeg2theora
0.18... it also works for ogv files created with ffmpeg2theora 0.24 and creates
ok concatenated ogv files playing files on vlc but it also says " warning:
found unknown stream, this stream will be ignored" and ogginfo shows no
Skeleton for concatenated file, so this must be the ignored stream because i can
see skeleton for the individual files before being concatenated... is this
important? does it make a change... if you like, you can download the individual
ogg and ogv files and oggcatted files from
https://www.yousendit.com/download/MnFqV0oxT01CSWQzZUE9PQ if you like... all are
less then 1MB_ you can see the ogg info for oggcatted files below...
also i encountered another problem while converting to ogg or ogv with both
ffmpeg2theora 0.18 & 0.24 (ogginfo is not here but even on thusnelda)__ some
of the converted files have some macro block artifacts on the very lower end of
the picture... this occurs for some files butdoesn't occur for other
files... but all of the input files have exactly the same specifications...
there is also one ok file in the yousendit download link above
named"OKNOBLOCKS_narrative.ogv".. you can see the ogg info for this
file also below... you can see the file with macro block artifacts also in that
zip file in the download link which is named "ff018
freedom.ogg"...ogginfo for this is also below.... both ok and macro blocked
input files have the same spesifications (mpeg2 program stream 320x240 1:1
10080kbps vbr mpeg1layer2audio 2 channels 48000hz 224kbps)... does anybody have
an idea what may the cause of this? i have tried -v 10 and V 10000 as well but
still the
artifacts are on for the same files....
here are the info for both catted 0.18 oggs and 0.24 ogvs and macro blocked and
ok files

Hi all,
I've cross compiled the Ogg Video Tools for Windows now, so you can join,
split, cut, cat, resize, thumbnail, create slideshows etc. under Windows now:
http://sourceforge.net/projects/oggvideotools/
But actually you have to use the command line :-/
