Subject: [PATCH] Fix ope_encoder_drain() assertion failure
|
|
|
|
If the stream is drained without writing any audio and the frame size is
|
|
smaller than the encoder latency, the assertion (enc->streams == NULL)
|
|
would fail because pad_samples was computed using an incorrect value of
|
|
enc->global_granule_offset before it was set in init_stream(), causing
|
|
the padding to be insufficient to drain the stream.
