encoders.
Public Methods
void AddBuffer (const CodecBuffer * buffer)Defined at line 7 of file ../../src/media/codec/codecs/vaapi/buffer_pool.cc
const CodecBuffer * AllocateBuffer (size_t alloc_len)Allocates a buffer for the caller and remembers the allocation size.
Defined at line 12 of file ../../src/media/codec/codecs/vaapi/buffer_pool.cc
void FreeBuffer (uint8_t * base)Frees a buffer by its base address, releasing it back to the pool.
Defined at line 30 of file ../../src/media/codec/codecs/vaapi/buffer_pool.cc
std::optional<Allocation> FindBufferByBase (uint8_t * base)Looks up what buffer from the pool backs a frame Ffmpeg has output.
Defined at line 43 of file ../../src/media/codec/codecs/vaapi/buffer_pool.cc
void Reset (bool keep_data)Removes all free buffers and re-arms the buffer pool to block when
servicing allocation requests.
If keep_data is true, does not modify the tracking for buffers already in
use.
If keep_data is false, old buffers are forgotten, and it's up to client
code to avoid calling FreeBuffer() regarding any old buffer.

void StopAllWaits ()Stop blocking for new buffers when empty.
Defined at line 60 of file ../../src/media/codec/codecs/vaapi/buffer_pool.cc
bool has_buffers_in_use ()Returns whether any buffers in the pool are currently allocated.
