--- Comment #16 from Vivia Nikolaidou <vivia at ahiru.eu> ---
14:43 < ndufresne> someone need to validate this, I guess it will be much
easier when I get the per element latency tracing working
14:44 < ndufresne> you need to test that couple of H264 streams, with different
profiles and specially different number of b-frames
14:44 < ndufresne> and then see if the latency match the required decoder
depth, or if it's totally random
14:44 < ndufresne> in ffmpeg, if you enable frame threading, it also introduce
1 frame latency (no matter how many thread you pick)
14:45 < ndufresne> ^ but that could easily be our fault, our decoder is not
thread and does not use the new read/write API
