This does not happen here: the encdec-dst.pgm file I get is just a
"low quality" version of the encdec-src.pgm file. Probably, the rate
control mechanism starts encoding the first frame with a low quality
(and the image you use as input requires a very high bitrate).

What is "asian-commercials-are-weird.flv"? Is it a video elementary
stream? If not, I do not think you can decode it with apiexample

Note that the video decoding example is hardcoding MPEG-1 as a video codec...
