libdvdread: UDFGetVolumeIdentifier fails

Reported by: stebbins@… Owned by: reimar

Description

UDFGetVolumeIdentifier calls UDFGetPVD calls UDFGetDescriptor which fails because bufsize is to small (8 bytes). The error is in the call.

if(!UDFGetDescriptor( device, 1, pvd_buf, sizeof(pvd_buf)))

sizeof(pvd_buf) gives the size of the pointer and not what it points at. It should be:

if(!UDFGetDescriptor( device, 1, pvd_buf, DVD_VIDEO_LB_LEN))

Seems to work with current libdvdread SVN.
