Hi there, I haven't been on this list until now, so I wasn't aware of this problem until last night ;-) - sorry for that. I am working on a patch for oggCut for that issue (looks good actually but I would like to do some testing befor I can release a patch.) Normal players are not effected by the page time misordering, so I took this issue as "minor". The reason for the

...to do so with granulepos. I have constructed a file which I believe should have its beginning truncated. I have attached it to this mail. Here is a picture of what the bitstream looks like, as output by a python program that uses pyogg/pyvorbis to read the stream and print a representation: <OggPage, BOS pageno = 0, granulepos = 0, serialno = 2079510926, head length = 28, body length = 30 at 0x4019b3e0> <OggPacket, BOS packetno = 0, granulepos = 0, length = 30 at 0x401e7bb0> <OggPage, pageno = 1, granulepos = 0, serialno = 2079510926, head length = 44, body length = 3877 a...

...l grap a bunch of raw data from a repository (e.g. a file) and place it into rawData. This rawData object is then placed into the oggDecoder. To find out if there is output data available, all media units provide the method isAvailable(): while (oggDecoder.isAvailable()) { oggDecoder >> oggPage; oggStreamDecoder << oggPage; } This can be done up until a frame or audio sample is available, but you don't have to. You can also place the data it into an oggEncoder and then into a new repository e.g. to split a stream (please refer to oggSplit as an example).

...ecent C++ libraries :-) If you want to try with liboggz, a good place to start would be the files in src/examples, such as fix-eos.c or rewrite-pages.c. I could also help anyone who wants to hack on hogg, where it's probably just a matter of writing a short helper along the lines of: sort :: [OggPage] -> [OggPage] sort = sortHeaders . listMerge . demux Anyway, an interesting problem :-) Conrad. 2009/6/18 Adam Rosi-Kessel <adam at rosi-kessel.org>: > I have over 1,000 ogg vorbis files that are no longer playable or > editable.

...ng the next vorbis or theora packet(s) and reading from the physical stream (+ split the streams to a vorbis or theora logical stream) if more data is needed. This works for theora streams with low dynamic data rates but not for my test streams, where from time to time a single keyframe needs 20-30 OggPages of data. Normally you can handle this by prebuffering some already decoded audio sample buffers or video frames but even with buffers of some megabyte this is in practise no solution because the audio decoder has to wait till theora is ready with reading/preparing/decoding it's pages. And b...

I have over 1,000 ogg vorbis files that are no longer playable or editable. I believe the main cause was a MediaMonkey plugin that automatically fetched album art and added it to the header. The plugin itself just uses the generic MediaMonkey metadata facility, but something happened -- perhaps when the album art bitmap image was too large -- that caused the files to no longer work.

I'm trying to generate the 4-byte crc code for the comment tag in an ogg file.. Can anyone point me to a function where this is done? Unfortunately, I can't use the lib directly, and the crc function I did find in it doesn't seem to do what I want directly. But, that might mean I'm not feeding it the right chunk of data. Any details would be helpful - yes I read the docs and I
