bufferpool: is it possible wait all memory writalbe, nor free the buffer?

[Bing Song]

Our expection of video buffer pool is reuse memory. Is it possible only release buffer to buffer pool when memory refer count is zero? Nor buffer ref count is zero.

Regards,
Song Bing.

That could be a way to solve the case where we discard buffers after
gst_buffer_make_writable() is called. A simpler plausible solution I had in mind, was to hook original buffer life time to the new buffer (in the case the memory are just reffed). I have not done any test of this.
