[PD] oggread~ not working on pd-extended or libpd on windows.

[Rafael Vega]

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)
