Decoding latency after writing bitstream data to decoder

[slavaman]

Hi! I used
After starting sending data to codec_write() there is a latency 100-200ms (milliseconds) after we get resulting image to a screen (fb0/fb1). For testing this issue I used simple example of video decoding (with an h264 raw bitstream). If we stop bitstream sending via codec_write() finction call, we do not obtain all the frames. Seems like there is kind of buffering or something.
Is it a bug or a feature? The latency between codec_write and screen output is up to 23 (twenty three) frames.
Is there any way to set 0-buffering to have 1in=>1out decoding?

p.s. This issue is observerd in
