H264 engine has this currently solved by allocating fixed size pool, which is not ideal. Most of the time pool size is much bigger than it needs to be. Ideally, extra buffer should be allocated at buffer initialization, but that's not efficient. It's size in H264 depends on flags set in SPS, but that information is not available in buffer init callback.
