Split binary sequence into more buffers (QByteArray).

[simozz]

I have a QByteArrary that I fill from a stream, more precisely the data are JPEG encoded frame (SOI = 0xffd8, EOI = 0xffd9), one after the other.

QByteArrary::split method only allow to search for a char character and not for a char * data type. Is there another way to look for a determined sequence in an a binary buffer ?

Of course I can develope my own function, but if there is something alredy done it would be perfect.

Thanks in advance.

@simozz You can use https://doc.qt.io/qt-5/qbytearray.html#indexOf-1 and then https://doc.qt.io/qt-5/qbytearray.html#mid
But this is a bit more work as just using split().

    const unsigned char soi[]={0xff,0xd8,0};
    const unsigned char eoi[]={0xff,0xd9,0};
    const int startOfItem = dataArray.indexOf(reinterpret_cast<const char*>(soi));
    const int endOfItem = dataArray.indexOf(reinterpret_cast<const char*>(eoi),startOfItem);
    if(startOfItem>0 && endOfItem>0)
    qDebug() << dataArray.mid(startOfItem,endOfItem-startOfItem+1).toBase64();
