Picture size 0x10 is invalid | video codec is not opened.What should be the reason?

Question

Right now am using RTMPStreamPublisher to publish the video at wowzaserver from iphone application. i have downloaded some demo code from this GitHub Project https://github.com/slavavdovichenko/MediaLibDemos/tree/master/RTMPStreamPublisher.

Now this sample is working great..but when i tried to create my own project with the same implementation then its giving me some error...am sure that there is not any kind of missing library or framework issue.. i had checked everything is same in my created project as per the demo they given..

but still don't know where am doing mistake... my error is as follows..

[NULL @ 0x181a0c00] [IMGUTILS @ 0x27d78630] Picture size 0x10 is invalid
[NULL @ 0x181a0c00] ignoring invalid width/height values
[flv @ 0x181a0c00] Specified pix_fmt is not supported
video codec is not opened
2013-11-28 12:39:27.064 LiveStreaming[268:60b] AudioCodec: codecID = 86050, codecType = 42, bitRate = 16000, _sampleBytes = 4
encoder supports the sample formats:
flt, 
audio codec best options: sample_rate = 44100
[nellymoser @ 0x18179a00] Specified sample_fmt is not supported.
audio codec is not opened

i really don't know what's the real problem...as there is just generalize error of EXC_BAD_ACCESS any idea??that what should be wrong??

NOTE: I am using following Library 

Just after creating the project i had added libraries and frameworks to it. Using the CommLibiOS and MediaLibiOS libraries requires to add the following frameworks: CFNetwork, AudioToolbox, AVFoundation, CoreFoundation, CoreMedia, CoreVideo, Security, and library libz.dylib.

Then added CommLibiOS and MediaLibiOS libraries to the project.
