 '''Expected results:'''
 
-    - APNG demuxer
-        - implement robust probing:
-            - PNG images are not misdetected as APNG animations
-            - APNG animations are not misdetected as PNG images
-        - splits stream into sensible packets (so they can be easily reused in APNG muxer)
-        - survives fuzzing (zzuf)
-        - add FATE coverage, coverage should be at least 70%
-        - test code under valgrind so no invalid reads/writes happen
-
-    - APNG decoder
-        - use existing PNG decoder code (write decoder in same file)
-        - implement parsing of all APNG chunks (acTL, fcTL, fdAT)
-        - error handling
-        - survives fuzzing (zzuf)
-        - add test for FATE, coverage should be at least 75%
-        - CRC checksum validation
-        - test code under valgrind so no invalid reads/writes happen
-
     - APNG muxer & APNG encoder
         - use existing PNG encoder code (write encoder in same file)

 '''Prerequisites:''' C coding skills, and you will need hardware that allows VDPAU post-processing.
 
-'''Qualification Task:''' Show that you are familiar with the FFmpeg filter system, either by porting one or more of the remaining postprocessing filters from the MPlayer compatibility layer (files `vf_*pp*.c` in `libavfilter/libmpcodecs`, see for comparison commits [http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=a2c547ff a2c547ff] and [http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=852f74bd 852f74bd]) to a native filter, or by implementing a very simple inverse telecine filter under LGPL that allows reversal of the effect of the telecine filter.
