# MediaCodec Recreation Issue Analysis
## Why MediaCodec Recreation is Needed
### Problem
MediaCodec is initially configured with `surface=nullptr` (CPU mode), but later we need it to output to ImageReader surface (GPU mode) when Vulkan device is registered.
### Android MediaCodec Limitation
`AMediaCodec_setOutputSurface()` API has limitations:
- Only works for video tunneling mode
- **Does NOT work reliably with async mode callbacks**
- Cannot change surface after codec is started in async mode
### Current Flow
1. `Initialize()` creates MediaCodec with surface=nullptr
2. MediaCodec starts with async callbacks
3. `SetVulkanDevice()` is called later
4. ImageReader surface is created
5. Need to switch MediaCodec output to ImageReader surface
6. **setOutputSurface() doesn't work in async mode → Must recreate codec**
## Current Issue After Recreation
Even after recreation, `getInputBuffer()` returns null for buffer indices from callbacks.
### Root Cause
**Race condition after `AMediaCodec_start()`:**
- Callbacks fire immediately when codec starts
- Buffer indices are enqueued (0-9)
- BUT codec internal buffer allocation isn't complete yet
- When `getInputBuffer()` is called with these indices → returns null
### Evidence from Logs
```
23:32:11.938 - Codec started, callbacks fire (indices 0-9 queued)
23:32:12.142 - DecodeFrameAsync gets index 0
23:32:12.142 - getInputBuffer(index=0) → returns null!
```
## Possible Solutions
### Option 1: Wait after start() then clear queue
After `AMediaCodec_start()`, wait 10-50ms for codec to stabilize, then clear old indices and wait for new callbacks.
### Option 2: Retry logic
If `getInputBuffer()` returns null, put index back in queue and retry with next index.
### Option 3: Don't recreate - use software decode path
Accept that async mode with surface switching doesn't work well, fall back to CPU decoding.
### Option 4: Change initialization order (BEST)
- Call `SetVulkanDevice()` BEFORE `Initialize()`
- But this requires changing application code
## Recommendation
Try **Option 1** first - it's the simplest fix:
```cpp
// After AMediaCodec_start()
std::this_thread::sleep_for(std::chrono::milliseconds(50));
// Clear old buffer indices
{
std::lock_guard<std::mutex> lock(m_async_handler->m_async_mutex);
while (!m_async_handler->m_async_input_buffer_queue.empty()) {
m_async_handler->m_async_input_buffer_queue.pop();
}
}
// Wait for new callbacks with valid buffers
```
