As this project is made up of a lot of separate small parts I'm going to focus on the code that is more relevant. Here is a status of the code; libav-bitrate.c: Fixed libav2yuv.c: I am refactoring this code completely using an OO model. libavmux.c: never worked. utilyuv.c: utility library, Fixed. vf_broadcast.c: needs changes to work with latest libav library vf_overlay.c: needs changes to work with latest libav library vf_watermark.c: needs changes to work with latest libav library yuv2jpeg.c: todo yuvGENERIC.c: template code yuvadjust.c: todo yuvafps.c: replaced by yuvaifps yuvaifps.c: todo yuvbilateral.c: todo yuvconvolve.c: todo yuvcrop.c: todo yuvdeinterlace.c: experimental yuvdeinterlaceB.c: experimental yuvdiag.c: fixed yuvdiff.c: todo yuvfade.c: limited use, may fix yuvfieldrev.c: todo yuvhsync.c: experimental yuvilace.c: experimental yuvnlmeans.c: experimental yuvpixelgraph.c: limited use, may fix yuvrfps.c: todo yuvsubtitle.c: todo yuvtbilateral.c: todo yuvtout.c: todo yuvtshot.c: replaced by yuvtout yuvvalues.c: todo yuvwater.c: todo yuvyadif.c: todo
