Hi,

Make sure that:
1. The timestamps from the demuxed data is properly injected into the
pipeline. Also the framerate and 
    sampling rates has to be set on the caps of respective appsrc so that
its propagated properly to the 
    respective sinks.
2. You are feeding full frames into appsrc. If you are not sure, better to
use the respective 
    elementary stream parsers before each decoder so that the decoder will
have a frame of data to decode.
    "h264parse" in case of h264 streams, "aacparse" to parse aac streams.
Your pipeline will look like:
        Appsrc - Elementary Stream Parser - Video dec - Video sink 
        Appsrc - Elementary Stream Parser - Audio dec - Audio sink
