Cannot write jpeg2000 with ERDAS 4.3 | GDAL 1.1
By ngarel in ERDAS ECW JPEG2000 SDK

Using gdal 1.10 and ERDAS 4.3 I'm having problems when writing JP2 files.
It fails at
oError = CNCSJP2FileView::Open( &(m_OStream) );
in ecwcreatecopy.cpp.

I think the problem comes with the way ERDAS library handles m_OStream.

I commented this block just before trying to open the output file:
    // if( bIsJPEG2000 )
    // {
    //     int bSeekable = !
    //       ( strncmp(pszFilename, "/vsistdout/", strlen("/vsistdout/")) == 0 ||
    //         strncmp(pszFilename, "/vsizip/", strlen("/vsizip/")) == 0 ||
    //         strncmp(pszFilename, "/vsigzip/", strlen("/vsigzip/")) == 0 );
    //     fpVSIL = VSIFOpenL( pszFilename, (bSeekable) ? "wb+": "wb" );
    //     if( fpVSIL == NULL )
    //     {
    //         CPLError( CE_Failure, CPLE_OpenFailed,
    //                   "Failed to open %s.", pszFilename );
    //         return CE_Failure;
    //     }

    //     m_OStream.Access( fpVSIL, TRUE, bSeekable, pszFilename, 0, -1 );
    // }  

which makes it fall in
oError = Open( (char *) pszFilename, false, true );
instead and works perfectly.

What is the benefit of using m_OStream? and could you confirm that the same problem occurs with you?

Hopefully ERDAS 5.0 will fix this issue
