read tagged information blocks: Time only block and Exposure only block

[mariniclaudio]

Hi there,
it would be great if also the tagged information blocks would be read out from the cine file, in particular the Time only block, which gives the timestamp of each image and the Exposure only block, which gives the real exposure time of each frame (it may vary for different frames). See page 30 of the cine file format manual (version 2011).
I could not find a way to load that information in the current pycine module.

Hi,
as I understand you right, you are searching for tag-type 1002 and 1003 as the timestamp and exposuretime of your frames. In the current version (4 months old) of pycine this is already included. If you already have the current version of pycine and no entries with "timestamp" and "exposuretime" as keys in the header dictionary, maybe you firmware of the camera of the PCC version is to old, so that it is not included in the files at all.

Hi there, thanks for the reply. You are right, I was referring to tag-type 1002 and 1003. I installed the release version with the command pip3 install -U pycine about 3 weeks ago, maybe I should have installed the development version? The measurements were done with the latest PCC version, and they contain the 2 tag-types. I know for sure because in the meantime I modified the pycine module to read out those blocks as well and it works just fine, thank you for sharing the pycine module, it was very useful for me to understand how to read the cine file, implementing the modification was relatively easy. Cheers, Claudio

Hi Claudio,
oh yes, you are right. The last release does no include the tagged block at the moment. Hence the developer version would have solved the problem. As there were several changes made in the recent past, no new release is published indlucing all the changes until now. Hopefully this can be done quite soon. Then e.g. also the new P12L compression will be supported.

Cheers,
Stefan
