[FFmpeg-devel] [PATCH] Add get_audio_buffer_ref to lavfi audio framework

[S.N. Hemanth Meenakshisundaram]

Fixed the get_audio_buffer_ref function so that it doesn't fill in the
buf->free function pointer by default. The client now needs to supply
the free function if providing the buffer.

If get_audio_buffer is called, this in turn allocates a buffer, calls
get_audio_buffer_ref and then fills in the free function pointer to
point to avfilter_default_free_buffer.

So there's no need for a flag or treating refcount differently.
