* copyToWorkDir
|
|
* Copies the source file to the worker's local workDir before processing.
|
|
*
|
|
* Use this plugin BEFORE any transcode/extract plugin when:
|
|
* - The source file lives on a network share / mapped drive
|
|
* - You want the worker to encode from a local copy to avoid I/O bottleneck
|
|
* - The network path is slow or unreliable during long encodes
|
|
*
|
|
* Flow:
|
|
* 1. Copies source → workDir/<basename><ext> (streams, no RAM load)
|
|
* 2. Updates outputFileObj._id to the local copy path
|
|
* 3. Downstream plugins operate on the local copy
|
|
* 4. Tdarr replaces the original with the final output as usual
