    4545This section lists well-defined projects that have one or more available mentors. If you are new to FFmpeg, and have relatively little experience with multimedia, you should favor a mentored project rather than propose your own. Contact the appointed mentor(s) to get more information about the project and the requested qualification task.

     47== H.264 Multiview Video Coding (MVC) == 
     48Image:Mmspg-epfl-ch-double-camera.jpg 
     49 
     50'''Description:''' MVC samples exist and the codec is used on Blu-ray media, but FFmpeg is missing a decoder. Since this project also consists of some changes in the current architecture, it is especially important that this project is discussed on the ffmpeg-devel mailing list. 
     51 
     52'''Expected results:''' Create MVC decoder and add a test for the FFmpeg Automated Testing Environment (FATE). 
     53 
     54'''Prerequisites:''' C coding skills, familiarity with git/source code control systems. 
     55 
     56'''Qualification Task:''' Perform work that demonstrates understanding of MVC and that is a subpart of the whole MVC implementation. 
     57 
     58'''Mentor:''' TBA, possibly Michael Niedermayer (michaelni on IRC) 
     59 
     60'''Backup mentor:''' TBA, possibly Kieran Kunhya (kierank on IRC) 
     61 
     62  
     63== Animated Portable Network Graphics (APNG) == 
     64 
     65'''Description:''' FFmpeg currently does not support Animated PNGs. 
     66 
     67Specification: https://wiki.mozilla.org/APNG_Specification

     69 
     70'''Expected results:''' 
     71 
     72   - APNG demuxer 
     73       - implement robust probing: 
     74          -  PNG images are not misdetected as APNG animations 
     75          -  APNG animations are not misdetected as PNG images  
     76       - splits stream into sensible packets (so they can be easily reused in APNG muxer) 
     77       - survives fuzzing (zzuf) 
     78       - add FATE coverage, coverage should be at least 70% 
     79       - test code under valgrind so no invalid reads/writes happen  
     80 
     81  - APNG decoder 
     82       - use existing PNG decoder code (write decoder in same file) 
     83       -  implement parsing of all APNG chunks (acTL, fcTL, fdAT) 
     84       - error handling 
     85       - survives fuzzing (zzuf) 
     86       - add test for FATE, coverage should be at least 75% 
     87       - CRC checksum validation 
     88       - test code under valgrind so no invalid reads/writes happen  
     89 
     90   - APNG muxer && APNG encoder 
     91       - use existing PNG encoder code (write encoder in same file) 
     92       - write compliant files, make sure they play correctly in major web browsers that support APNG 
     93       - add test for FATE  
     94 
     95'''Prerequisites:''' C coding skills, familiarity with git/source code control systems. 
     96 
     97'''Qualification Task:''' Implement format autodetection for imagepipe & image demuxer 
     98 
     99'''Mentor:''' TBA, possibly Paul B Mahol (durandal_1707 on IRC) 
     100 
     101'''Backup mentor:''' TBA, possibly Peter Ross (pross-au on IRC)  
     102

    47104== FFv1 P frame support ==
