- * Camera metadata parser class. Usage as shown below.
- *
- * Setup:
- *
- * Usually the metadata parser will be made as part of the CamHelper class so
- * application code doesn't have to worry which kind to instantiate. But for
- * the sake of example let's suppose we're parsing imx219 metadata.
- *
- * MdParser *parser = new MdParserSmia({ expHiReg, expLoReg, gainReg });
- * parser->SetBitsPerPixel(bpp);
- * parser->SetLineLengthBytes(pitch);
- * parser->SetNumLines(2);
- *
- * Note 1: if you don't know how many lines there are, the size of the input
- * buffer is used as a limit instead.
- *
- * Note 2: if you don't know the line length, you can leave the line length unset
- * (or set to zero) and the parser will hunt for the line start instead.
- *
- * Then on every frame:
- *
- * RegisterMap registers;
- * if (parser->Parse(buffer, registers) != MdParser::OK)
- *     much badness;
- * Metadata metadata;
- * CamHelper::PopulateMetadata(registers, metadata);
- *
- * (Note that the CamHelper class converts to/from exposure lines and time,
- * and gain_code / actual gain.)
- *
- * If you suspect your embedded data may have changed its layout, change any line
- * lengths, number of lines, bits per pixel etc. that are different, and
- * then:
- *
- * parser->Reset();
- *
- * before calling Parse again.
