Hi,

I'm recording video with GStreamer in iMX6S which use hardware video encoder. When I run program, I receive this message:

====== IMXV4L2SRC: 4.0.9 build on Dec 9 2016 00:05:14. ======
[INFO] Product Info: i.MX6Q/D/S
====== VPUENC: 4.0.9 build on Dec 9 2016 00:05:34. ======
wrapper: 1.0.65 (VPUWRAPPER_ARM_LINUX Build on Dec 8 2016 23:59:08)
vpulib: 5.4.33
firmware: 3.1.1.46072
[INFO] ringBufferEnable 0, chromaInterleave 1, mapType 0, linear2TiledEnable 0
[WARN] VPU iram is less than needed, some parts don't use iram

And after that 3.6 s, video has been recorded. So my question is, what does system do in that 3.6 seconds. And how can I reduce this time ? 

Thank you so much,

Toan
