|

|

* would go on passing if it stopped.
|
||||
*
|
||||
* Measured rather than asserted: mutating `concatInputFrom`'s initial `video` to a non-null
|
||||
* placeholder leaves `ConcatPlannerTest` green and turns this red.
|
||||
*
|
||||
* ## The asymmetry this protects
|
||||
*
|
||||
* `ConcatPlanner` guards its video check against a null codec (`ConcatStrategy.kt:51`) and its
|
||||
* audio check not at all (`:54`). **That is correct, not an oversight.** `MediaProbe.shortName`
|
||||
* returns a non-null `String`, so in `concatInputFrom` a null `audioCodec` means the track is
|
||||
* *absent* — and two clips with no audio genuinely do match. A null `videoCodec` carries both
|
||||
* meanings, absent or unreadable, which is why only that one is guarded.
|
||||
*
|
||||
* So the audio check is safe *because* the video guard fires first on a clip nothing could read.
|
||||
* Nothing wrote that coupling down and nothing held it.
|
||||
*
|
||||
* ## What this deliberately does not cover
|
||||
*
|
||||
* `probeForConcat`'s `catch` arm (`MediaProbe.kt:300-302`). It is **not reachable on the JVM**:
|
||||
* Robolectric's `MediaExtractor` never throws from `setDataSource`, measured across an
|
||||
* unregistered `content://` authority, a missing `file://`, a file of garbage bytes and an `http://`
|
||||
* URL — all four returned normally with `trackCount = 0`. So the failure arrives here as an empty
|
||||
* track list rather than as an exception, which reaches the same `ConcatInput(null, null, 0, 0, 0)`
|
||||
* by the other road. The catch stays device-only, and this file does not pretend otherwise.
