问题 Is there a way to extract the duration information from a video file's metadata (or maybe calculate the duration some other way) in python without invoking an external process. I've found a number of answers that reference using ffprobe but that isn't an option for me. I need this to be all self contained within the python app. The file formats I need to process are .mp4 , .mov , .mxf and preferably as many other common video file formats as possible. Edit: I am using python 3.x so

问题 I'm working on a program which requires 8BIM profile information to be present in the tiff file for the processing to continue. The sample tiff file (which does not contain the 8BIM profile information) when opened and saved in Adobe Photoshop gets this metadata information. I'm clueless as to how to approach this problem.

问题 Is there a way to attach a piece of metadata to a MySQL database? I'm trying to write code to automatically update the database schema whenever a code upgrade requires it. This requires the storage of a single integer value -- the schema version. I could of course create a whole table for it, but that seems like overkill for just a simple number. 回答1: You can use table comments to store the version: ALTER TABLE table1 COMMENT = '1.4'; You'll have to regex to get the comment from this: SHOW
