Bug: updateSourceCaches_() assumes srcObj has src and type properties

Severity: Low
Files: src/js/player.js
Lines: 1582-1585

Description

When srcObj is a non-string object, the code accesses srcObj.src and srcObj.type without checking if these properties exist. If srcObj is null, {}, or an object with different keys, src and type will be undefined, leading to silent failures.

Affected code

if (typeof src !== 'string') {
  src = srcObj.src;   // <-- Could be undefined
  type = srcObj.type; // <-- Could be undefined
}

Suggested fix

if (typeof src !== 'string') {
  src = srcObj?.src ?? '';
  type = srcObj?.type ?? '';
}
