Follow up:

Looking at the code for oggread~, I found that it does the actual opening of the file with        

    if(ov_open(x->x_file, &x->x_ov, NULL, -1) < 0)

on the ov_open documentation it warns windows programmers not to use ov_open but ov_open_callbacks instead [1] and [2] so I changed that line to the following and I'm getting the message "Bitstream does not contain any Vorbis data". I'm pretty sure my file is a valid ogg file. I created it using audacity and also tried with an ogg file downloaded from freesound.org.

Any help with this will be very much appreciated

:)

        int ret = ov_open_callbacks(x->x_file, &x->x_ov, NULL, -1, OV_CALLBACKS_DEFAULT);
        switch(ret){
            case OV_EREAD:
                 post("A read from media returned an error.");
                 break;
            case OV_ENOTVORBIS:
                post("Bitstream does not contain any Vorbis data");
                break;
            case OV_EVERSION:
                post("OV_EVERSION - Vorbis version mismatch.");
                break;
            case OV_EBADHEADER:
                post("Invalid Vorbis bitstream header.");
                break;
            case OV_EFAULT:
                post("Internal logic fault; indicates a bug or heap/stack corruption.");
                break;
        }
        if(ret <0)

Hi.

I am trying to use [oggread~] external on an application i'm developing with libpd. No problems on mac or linux. Howerver, on windows (xp and 8, 32bit) I keep getting an error message from oggread~ when I try to open an ogg file. Even ogg_read~-help.pd won't work:

oggread~: file "C:/Users/rv/any.ogg" opened
oggread~: error: could not open "C:/Users/rv/Desktop/any.ogg" as an OggVorbis file
oggread~: file closed due to error

I have tried pd-extended (both installer and standalone) and I also compiled oggread~ into my application and loaded it with libpd, same outcome.

The weirdest part is that if I run pd vanilla, copy oggread~.dll from pd-extended into the "extra" directory, the ogg files are opened correctly.

Any ideas on how to make this work? What kind of debug info can I provide?
