[Libav-user] Reoder Buffer Configuration

[k***@iwavesystems.com]

Hi,

I am getting Following warning during h264 decoding using libavcodec:

Increasing reorder buffer to 1
Increasing reorder buffer to 16

Can I avoid this warning?
Size of the frame reordering buffer in the decoder is set by libavdodec
itself.
What is the reason for this warning?

Thanks in advance
KP

On the faceo f it, your input stream contains B-frames, but the headers do
not declare that, so ffmpeg adapts its decoder on the fly. You should not
worry about this, unless the result is not satisfactory.

Definitely!
(Although I don't know much about the reorder buffer.)

Please do not top-post here, Carl Eugen

That means Delay will be there?? which is not at all acceptable. Any way is
there to avoid this?
One more thing is transmitter (Camera) sending only i-frames. not B-frames.
Then how this print is comming?

You could run ffmpeg with "-debug pict" or maybe more debug options.
