Analyzing MPO file

[saratoga]

Hi,

I would like to inspect the  MPO(Multi-Picture Format) files. The Exiftool with no option reports MPF information of First individual image only.
I need MPF information of all images(individual image #2, #3, #4,.....#n). Is there any option to do so?

Thanks!

From the MPF tag name documentation:

The first MPF "Large Thumbnail" image is extracted as PreviewImage, and the rest of the embedded MPF images are extracted as MPImage#. The ExtractEmbedded (-ee) option may be used to extract information from these embedded images.

Thank you for your reply.

But 'Extract information from embedded files'(-ee) option does not help me.
It yields same output about MPImage2 as with no option.

with -htmldump -ee option;
<div id=p249 class=tt><b>JPEG EOI</b><br>(2 bytes)</div>
<div id=p250 class=tt>[Unknown trailer]<br>(32 bytes)</div>
<div id=p251 class=tt>(MPImage2:MPImage data)<br>Size: 1614827 bytes</div>
</body></html>

with -htmldump option;
<div id=p128 class=tt><b>JPEG EOI</b><br>(2 bytes)</div>
<div id=p129 class=tt>[Unknown trailer]<br>(32 bytes)</div>
<div id=p130 class=tt>(MPImage2:MPImage data)<br>Size: 1614827 bytes</div>
</body></html>

The Exiftool reports detail information  about MPImage1.

<div id=p120 class=tt><b>MPF1 entries</b><br>Entry count: 4<br>(2 bytes)</div>
<div id=p121 class=tt><b>MPF1-00 MPIndividualNum</b><br>Tag ID: 0xb101<br>Format: int32u[1]<br>Size: 4 bytes<br>Value: 1</div>
<div id=p122 class=tt><b>MPF1-01 BaseViewpointNum</b><br>Tag ID: 0xb204<br>Format: int32u[1]<br>Size: 4 bytes<br>Value: 1</div>
<div id=p123 class=tt><b>MPF1-02 <span class=H>ConvergenceAngle</span></b><br>Tag ID: 0xb205<br>Format: rational64s[1]<br>Size: 8 bytes<br>Value offset: 0x0088<br>Value: 0 (0/1)</div>
<div id=p124 class=tt><b>MPF1-03 <span class=H>BaselineLength</span></b><br>Tag ID: 0xb206<br>Format: rational64u[1]<br>Size: 8 bytes<br>Value offset: 0x0090<br>Value: 0.077 (77/1000)</div>

I would like to know MPIndividualNum, BaseViewpointNum, ConvergenceAngle, BaselineLength, etc. of MPImage2 (All MPimages on MPO file that has many images).
Is there difficulty to do so on current version?

Thanks!

The -ee option doesn't work with -htmldump.  To do this you must extract the image then run -htmldump on the separate image:

exiftool -mpimage2 -b SRC.mpo | exiftool -htmldump - > out.html

My problem has been solved. Thank you very much.
I was impressed with the Exiftool can do pipeline processing like UNIX manner.
By the way, If the Exiftool was invested with a option of parsing recursively nesting structure of MPO file (especially with -htmldump), it would be useful on some occasions.
Anyways, I have recognized that people who handle MPO files can get benefit from the Exiftool.

Thank you.
