...an't figure out what's wrong with my code. I'm hoping that there's some glaring error that you guys will shout at me for missing. This method is called when enough data has accumulated in inputFrame, after the members have been initialized and the headers have been written: oggPacketCount++; speex_bits_reset(&speexBits); speex_encode_int(encoderState, inputFrame, &speexBits); int packetBytes = speex_bits_write(&speexBits, packetBuffer, PACKET_BUFFER_SIZE); oggPacket.packet = (unsigned char*)packetBuffer; oggPacket.bytes = packetBytes; oggPa...

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 at 0x4019b368> <OggPacket, packetno = 1, granulepos = -1, length = 45 at 0x401e7bb0> <OggPacket, packetno...

...ed to operate like this. SetupCodec when i have data to give to the codec FeedDataToCodec(data) //Receive a bunch of callbacks somewhere returning me pcm data //Codec waits for more data and doesn't reset itself. I will always give it a complete ogg packet as a buffer (but not in an oggpacket struct because directshow uses a different sample structure.) and size. And i need it to process the data i give it and then wait until i give it some more. There is no way the codec can read data unless i give it to it. And incidentally i use my own demuxer written in C++ and not libogg. So i hav...

I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my

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

Hey i've recently written some directshow filters for ogg vorbis and speex (www.illiminable.com/ogg/) and i thought i might add flac too... i've had a quick look at the C++ api and it appears that the decoding works by having a read callback to get it's data. In directshow everything is pushed into the decoder it can't ask for data when it wants... i'm just wondering if there

Hello everybody ! I am working on a php class to enable, on the server-side, to extract useful data from Ogg theora videos. http://opensource.grisambre.net/ogg . I need to have it extract a thumbnail picture from a video (much like dailymotion or youtube). Right now, I am doing it using the ffmpeg-php extension (for picture extraction only), but the problem is that this module is available on

Hi everybody, I posted here about two years ago about the initial release. This is a release that fixes many bugs, and has enhancements that make it possible to support a multi-stream format, ALingA, which I will mention briefly later. It also supports a PCM format, Neuro, both as part of the multi-stream codec, and stand-alone. libogg++ is a C++ library implementing Ogg. It is designed to be
