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 1000 clients in a day, integrity of live

Fixing ogg vorbis corruption caused by bad metadata

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

It's a fundamental limitation of this type of streaming that the duration can not be determined beforehand and

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,

Fixing ogg vorbis corruption caused by bad metadata

I just realized that the hogg tools will fix the CRC issues (by design accident: hogg ignores the CRC on reading but sets it correctly on writing). "hogg rip" rewrites the pages (fixing the CRC), and "hogg reconstruct" also rewrites the I've uploaded the outputs of

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://pygstdocs.berlios.de/ - 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 info on

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

Re: Souffleur subtittle editor (SoC). Need Help with GStreamer
...oogle evaluations are due at the end of June. You can rework it to use gstreamer properly later. That just leaves getting playback and scrubbing working. You might look at Andy Wingo's theora clip trimmer for an example of that: http://webcvs.freedesktop.org//gstreamer/gst-python/examples/remuxer.py There's also thoggen, but I don't think that's been ported to gstreamer 0.10, which is definitely what you should be using. http://thoggen.net/svn/ Hope that helps, and looking forward to seeing souffleur play video! -r

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.

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
