<DIV>Hi Ross,</DIV>
<DIV> </DIV>
<DIV>I am currently testing Live555 based application on Freescale’s i.MX51
platform, the camera frames are encoded by Hardware encoder (H.264 format). The
encoded frames are sent to deliverFarme without any modifications. After
this I am streaming over UDP.</DIV>
<DIV> </DIV>
<DIV>With reference is taken from DeviceSource.cpp, I am able to stream but
following warnings are displayed continuously.</DIV>
<DIV> </DIV>
<DIV>....</DIV>
<DIV>Warning: Invalid 'nal_unit_type': 0. Does the NAL unit begin with a
MPEG 'start code' by mistake?</DIV>
<DIV>Warning: Invalid 'nal_unit_type': 0. Does the NAL unit begin with a
MPEG 'start code' by mistake?</DIV>
<DIV>....</DIV>
<DIV> </DIV>
<DIV>My understanding is that it is expecting some NAL units in the encoded
frames.</DIV>
<DIV> </DIV>
<DIV>I am running mplayer as the client in the linux machine which displays
following messages without displaying the video frames.</DIV>

<DIV>Gone through the </DIV>

<DIV><STRONG>::afterGettingFrame1 </STRONG>method but not able to catch what
exactly being done there.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Please let me know the reason behind this and the way to solve it.</DIV>
