| | 47 | == H.264 Multiview Video Coding (MVC) == |
| | 48 | Image: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. |

| | 63 | == Animated Portable Network Graphics (APNG) == |
| | 64 | |
| | 65 | '''Description:''' FFmpeg currently does not support Animated PNGs. |
| | 66 | |
| | 67 | Specification: https://wiki.mozilla.org/APNG_Specification |
| | 68 | Image:Animated PNG example bouncing beach ball.png |
| | 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 |
