Protected Methods
void ProcessInputLoop ()Processes input in a loop. Should only execute on input_processing_thread_.
Loops for the lifetime of a stream.
void CleanUpAfterStream ()Releases any resources from the just-ended stream.
std::pair<fuchsia::media::FormatDetails, size_t> OutputFormatDetails ()Returns the format details of the output and the bytes needed to store each
output packet.
Subclasses can assume this is only called after the stream's format details
have been processed on `input_processing_thread_` and before
`CleanUpAfterStream()` resets per-stream format state. When reached through
`CoreCodecGetOutputFormat()` in production,
`CodecImpl::onCoreCodecOutputPacket()` calls this synchronously on
`input_processing_thread_`. Implementations must still acquire `lock_` when
reading per-stream format state (such as `codec_params_` or `context_`) so
that direct callers (such as unit tests) and any future off-thread callers
are safe.
void WaitForInputProcessingLoopToEnd ()Defined at line 274 of file ../../src/media/codec/codecs/sw/codec_adapter_sw.h
void LoadStagedOutputBuffers ()We don't give the codec any buffers in its output pool until
configuration is finished or a stream starts. Until finishing
configuration we stage all the buffers. Here we load all the staged
buffers so the codec can make output.
