similar to: play a ogg file from a given buffer instead of a file

Thanks for your answer. But as I said, I don't have any problem seeking in a local file. Also, I have full control on the ogg file I play, since I encode it by myself. I first would like to know if the code I provided ( https://gist.github.com/mregnauld/3f7cdc43b02ec3bbd91641b9333ba072) is good practice when it comes to extracting and seeking in a file that is being downloaded. Thanks.

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

Hi all, I'm very new to Ogg, and am learning about it in an attempt to stream it from a CF card through a microcontroller. This particular setup requires me to move parts of the file from the CF card to the microcontroller buffer, effectively making the file like a data stream. Also, should this question be directed at the Tremor group instead since that is the codec I'm using? It

Hi, I've been working with oggvorbis-win32sdk-1.0.1 and have a semi-hypothetical question. Let's suppose that, for whatever reason, I've allocated a block of memory, and I've loaded into this memory a perfectly valid ogg vorbis file. Now I'd like to decode this vorbis data, but I'm stuck calling ov_open() because I don't have a FILE*, I have a block of memory. (This

Hello, I'm currently trying to implement streaming off ogg-files out of an archive file using SDL and SDL_mixer for playback. Therefore i create a FILE * filepointer, place it to the beginning of an ogg file inside the archive and hand over the filepointer to ov_open. ( command: ov_open(fp, &music->vf, NULL, 0) ). This works fine so far. The problem is: if i put many oggs together in

Hello, I've been looking to the libvorbisfile and got into troubles when trying to use it: I need to compile it on a PalmOS and the libvorbisfile must be compiled in ARM whereas calling code is in 68K. This implies that the interface ov_open_callback is not usable because the OggVorbis_File *vf must point to something in the target architecture (ARM) whereas the caller cannot do that. As

Hi folks, i would like to know if it is valid to load a whole .ogg file into memory and call ov_open like this: ov_open(NULL, &OggVorbisFile, pRawData, RawDataLen); An other question is, is it valid to copy some ogg files into one (resource) file, position the filehandle and use ov_read to read only the ogg file which starts at the current position of the file handle? (In other words, does

Hello all. I'm new to this list. I'm also new to coding with libvorbis and things, so please bear with me. :) I've been having trouble with libvorbisfile. My use of it is fairly simple, but when I try to ov_clear the vorbis file, it segfaults. I can attach or otherwise make availible some demo source code, but for now I'll just pull out relevant lines: //BEGIN PSEUDO CODE

I'm in the final throes of debugging (hopefully) and the last thing I'm trying to do is figure out why I'm getting static instead of usable data. I have a verified Ogg file (it plays fine in WMA); I've visibly inspected the info struct and it matches my output format; I've verified my audio playback code by using a generated sine wave (sounds correct). So that leads to a

I've been playing around with using ov_test and ov_test_open as an alternative to ov_open in the xmms plugin's vorbis_check_file function. xmms never bothers to cache the result of a file check, so it tends to happen rather a lot. Unfortunately ov_test_open returns OV_EINVAL because ov_test seems to have left vf->ready_state to OPEN rather than PARTOPEN. I'm presuming this is

Hi there. I have been hearing to ogg vorbis for maybe 2 years and I can only say: it is fantastic! Right now, I'm working in a project that uses ogg vorbis as the format for recording. I have now a working recording engine (I have recorded up to 8 channels at the same time and my computer uses only about 30% of the processor, wich is great in this project), and I'm starting with the

yes, you are right. i always search for quick and easy solution and forget in the meantime that vorbis is a low level codec library. so probably a wrapper lib is the right way. but as far as i understand vorbisfile is already a bunch of convenience functions? so to speak a wrapper lib ? so why not enhance a little bit vorbisfile ? and - i did not felt personally attacked. i just wanted to note

Hi guys, I'm writing a sample playback engine using vorbisfile, but I've hit a performance problem - hoping someone here can help! I'm using ov_open_callbacks() to decode memory-based ogg files. It works OK, but when I call ov_open_callbacks() approximately 300k of memory is used (presumably to initialise the decoder). It also takes some time to execute ov_open_callbacks() - the read

Hi, I am devloping a basic ogg player. I have taken help from this turorial: http://www.devmaster.net/articles/openal-tutorials/lesson8.php Thanks to jesse. It is using openAL and ogg sdk.

Dear members, since two weeks I am stuck, trying to demux a physical ogg stream (theora and vorbis) and play the audio part using vorbisfile. I hope that one of you can give me a hint or point me to additional documentation. I used ogg.h and vorbisfile.h. The way so far: - initializing an ogg_sync_state - inserting data to sync_state using ogg_sync_buffer - when whole page found

I have a problem i suspect to be a bug in ogg: Assume i have a simple archive "chou_s_test1_test2.pak", created by simply concatenating binary files together: chou_s.jpg (3403 bytes) test1.ogg (5196 bytes) test2.ogg (6128 bytes) If i place the a filepointer passed to ov_open to the beginning of test1.ogg, this ogg gets opened and decoded correctly. But if i place it to the beginning

Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so long to open OGG file? The OGG file has just 210 MB. It takes a lot of time open the file. I am working on OGG audio recorder and player. Thanks in advance! With kind regards, Pavel

I passed a valid FILE* (from fopen() with "rb") and the address of an OggVorbis_File struct, but an access violation occured when ov_open is called. I have enabled the Multithreaded, but it still doesn't fix the problem. I look at the vorbis_comment.exe source and I see vcedit_open() function and other vcedit_*() functions everywhere. I am assuming that there is known issue with VC
