Сбой предварительного просмотра камеры на некоторых камерах ⇐ Android

[Anonymous]

Я разрабатываю приложение камеры, и на данный момент я предварительно просмотр всех камер. Я могу войти в систему до 8 идентификаторов камеры.
Прогресс: я могу переключаться между камерами и увидеть предварительный просмотр от идентификатора камеры 0 на идентификатор камеры 5. С помощью максимального разрешения, которое поддерживается для этого датчика.
Проблема: Итак, прямо сейчас идентификатор камеры 6 и 7 вызывает ошибку: < /p>
GraphicBufferAllocator E Failed to allocate (4000 x 3000) layerCount 1 format 34 usage 100: 1
BufferQueueProducer E [SurfaceTexture-0-20260-0](id:4f2400000001,api:4,p:1664,c:20260) dequeueBuffer: createGraphicBuffer failed
BufferQueueProducer E [SurfaceTexture-0-20260-0](id:4f2400000001,api:4,p:1664,c:20260) requestBuffer: slot 0 is not owned by the producer (state = FREE)
< /code>
Теперь дело в том, что этот 4000x3000 работает для другого идентификатора камеры 4. Поэтому я не могу понять, почему это сбои на идентификаторе камеры 6 и 7.
Примечание: приложение состоит в том, чтобы предоставить высокое разрешение и FP от датчика, вместо этого предварительно выкомпированные, чтобы получить полный потенциал от устройства; Для создания контента. < /p>
Это функция, вызванная при запуске предварительного просмотра: < /p>
fun chooseAndApplyPreviewSize(cameraId: String?, currentResolution: Resolution?): android.util.Size {
val camId = cameraId ?: return fallback()
val supported = ResolutionManager.getSupportedResolutions(context, camId)
if (supported.isEmpty()) {
Log.w(TAG, "No supported resolutions discovered for camera $camId, using fallback")
return fallback()
}

// Logging sample sizes
try {
val sizesOnly = supported.map { "${it.width}x${it.height}" }.distinct()
Log.d(TAG, "Camera $camId supported sizes (sample): ${sizesOnly.take(20)} (total ${sizesOnly.size})")
} catch (_: Exception) { /* ignore */ }

val chosenRes = currentResolution?.let { cr ->
supported.firstOrNull { it.width == cr.width && it.height == cr.height && it.fps == cr.fps }
} ?: ResolutionManager.selectDefault(supported) ?: supported.first()

val chosenSize = android.util.Size(chosenRes.width, chosenRes.height)

// If same as last applied -> return quickly
if (lastAppliedPreviewSize == chosenSize && previewSurface != null) {
Log.d(TAG, "chooseAndApplyPreviewSize: chosen size unchanged ${chosenSize.width}x${chosenSize.height}")
return chosenSize
}

Log.d(TAG, "chooseAndApplyPreviewSize: reconfigure to ${chosenSize.width}x${chosenSize.height}")

// reconfigure: set flag so callers can avoid racing operations
isReconfiguringPreview = true

// Apply buffer size and recreate previewSurface safely
val st: SurfaceTexture? = textureView.surfaceTexture
if (st != null) {
try {
st.setDefaultBufferSize(chosenSize.width, chosenSize.height)
// release old preview surface if present
try { previewSurface?.release() } catch (_: Exception) {}
previewSurface = Surface(st)
Log.d(TAG, "Applied SurfaceTexture buffer size = ${chosenSize.width}x${chosenSize.height} for camera $camId")
} catch (e: Exception) {
Log.w(TAG, "Failed to set default buffer size: ${e.message}")
}
} else {
Log.w(TAG, "SurfaceTexture is null when trying to set buffer size")
}

lastAppliedPreviewSize = chosenSize
isReconfiguringPreview = false
return chosenSize
}
