DIVE Desktop Functionality for Video transcoding[FEATURE]

[BryonLewis]

Adding in the ability to transcode video files on the desktop before displaying them.

Couple of updates to note as I went through and started on this:

• Importing of files needs to be different than loading files. Before it was the same action
• Need to inject jobs and the jobHistory updating into the importing of files
• Going to run each individual video as it's own job. Image sequences will be run as a single job executing the commands sequentially. Meaning it goes through and does Image1.tif, then image2.tif and so on until the full job completes.
• We probably want a concept of job queuing so we only run one job at a time. I'm not at thinking about this yet
• Add in error handling if FFMPEG can't be found because the VIAME directory is wrong.
• ffmpeg-static and ffmpeg-static-electron are ways to bundle the ffmpeg and there are corresponding ffprobe ones that can be used. I'm not worrying about that right now and am using the Kwiver one built in.

Added in a temporary system for conversion just as a proof of concept that it works properly and convert the data. I'll need to test it on larger datasets.

Two things are needed for support integration with project files:

• Ability to hook into the "Import" process and generate a job which blocks loading of the dataset.
• Knowing the destination of the import for where I should place these new files

Left to do on my end:

• - Obviously the integration with the project system
• - Updating the imagePath and videoURLs after conversion is complete to point to the new files
• - Warning if VIAME Path isn't setup because ffprobe and ffmpeg wouldn't be found.
• - Some scaling testing on large image sequences and if creating a large chained ffmpeg command has any issues.
• - Update the image conversion system to stop using && and do actual array spawning a new process for each conversion
• - Job queuing system to prevent all jobs from being kicked off at once.
