Webm files written without duration in header
Hi there
Thanks Thomas. I was hoping to avoid remuxing as my objective is to run an
extremely lightweight server. Just tested and the CPU runs between 9% and
23% for a lecture of 90 minutes - took 18sec. Yes it's a lightweight
server, but like I said, that's the objective, and quite a nice challenge
:-) CPU = cost and if you have to remux for 1...

The second page is corrupt. The basic structure looks correct, first
guess would be bad checksum. I'll look more closely in just a bit.
This might explain why some players might accept it--- if

Webm files written without duration in header
Dear all
I am streaming live with webm with ffmpeg to icecast 2.4.2. After the
stream ends, I am unable to determine the duration of the file using
ffprobe or mediainfo. Not sure but it seems that this has to do with
headers?
Should icecast be writing the duration into the header or should this
somehow be passed from ffmpeg?
The requirement is really to determine the duration of the streamed

Ah, yes, and CMML supplies a way to specify addresses which are
then interpreted by this algorithm. Have I got that right ?

...s will not be changed. Only the WebM container
information gets rewritten. If there are malformed portions of the
stream (caused by e.g. CPU starved encoder or network stall), then those
might get removed though as a player wouldn't play them properly either.
There are many dedicated tools for remuxing MKV and or WebM.
A somewhat brute-force quick fix is of course: `ffmpeg -i foo.webm -c
copy bar.webm`

Delayed pages ?
Hi all !
I am experiencing a strange issue with the theora encoding process.
Apparently, when I put packets into the ogg stream, the pages are not returned
immediately by ogg_stream_pageout. What happens seems that I get several
pages at once later.
This causes me trouble since then the pages are not properly placed with the
other vorbis audio pages, leading to warnings in oggz-validate,

Souffleur subtittle editor (SoC). Need Help with GStreamer
Hi, All!!!
I am at last added some GStreamer support to the Souffleur, and I am
already read this manuals:

-
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/index.html
But it's steel hard for me to understand (or maybe I something missed)
how it work. :(
For example: I don't know where to search info on how to load additional

While this is possible to do it this way (and probably a good idea for the
examples like a clock in a corner), it implies that all the placements and
logically different "items" are known at the start of the stream (since the
Ogg spec says a

How's this coming? Was Mike's response helpful?

perhaps an ID (labelled by Content-ID or similar) is more robust. By
the ogg spec, serialnos need to be changed when chaining etc., which
would further complicate the remuxing of content with skeleton.

my proposal for these stems from Debian package relationships, where
Provides, Depends, Recommends, Suggests, Conflicts are defined locally
to each package. In aggregate (considering the whole universe...

theora editing
hello theora-list,
i'd like to edit (especially crop) theora files I downloaded here and
there. But as far as I know, there is no theora editor.
Is there a cli theora files editing ?
How could I export .ogg files into whatever format that i can then edit
with software such as avidemux ?
thanks very much

Can ogg file contain VP8 frames
Hi All
Is it a possible case that an ogg file contains VP8 frames.
I know ogg file generally contains vorbis, theora frames.
Recently I came across an ogg file that contains OPUS frames.
Is there any tool, that can take a webm file as input, and output an ogg
file with preferably only video (no audio) frames.
Please let me know.
Thanks
Austin

Guadec 2005 and DirectShow Filters
Hello all,
I have been trying to play the Guadec Theora files (
http://stream.fluendo.com/archive/6uadec/ )
on Windows with no success. At first I thought it was just the machine
which I was trying it on, but I now have seen another machine play other
Theora files (Systm, Ubuntu Below Zero) without problems, but treat
Guadec as just being audio files. I do also have another machine here
which
