Comment (by cehoyos):

 Replying to [comment:14 dalecurtis]:
 > ffmpeg -acodec libfdk_aac -i ssr_chrome.aac -acodec libfdk_aac out.mp4
 This produces a stream here that plays for approximately 19.5 seconds,
 just as the original file you attached with the native decoder.

 I also wonder why you believe that libfdk works so much better for this
 sample if re-encoding to aac with libfdk produces a shorter file.
