I was looking for an OCR app to use with Gnome\/Gentoo and decided to give OCRFeeder<\/a> a try. \u00a0It is available in the an overlay which makes it easier to keep up with for updates. \u00a0It is found in the anyc<\/a> overlay.<\/p>\n

layman -a anyc \u00a0then \u00a0emerge ocrfeeder (have to unmask)<\/p>\n

WTF!!! A lot of rebuilds and new packages … that means probable trouble. \u00a0Yep, mplayer2 will not compile. \u00a0One of the updates was for ffmpeg and that had me worried that I had run into my first libav–ffmpeg blowup<\/a>\u00a0because I use ffmpeg rather than the mandated libav.<\/p>\n

So, I unmask\u00a0mplayer2-2.0_p20131009-r1 and still get the error:<\/p>\n

libmpdemux\/aviheader.c: In function ‘read_avi_header’:<\/em>
\n libmpdemux\/aviheader.c:600:8: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result [-Wunused-result]<\/em>

\n #error MP_INPUT_BUFFER_PADDING_SIZE is too small!<\/em>
\n ^<\/em>
\n Makefile:536: recipe for target ‘libmpdemux\/demuxer.o’ failed<\/em><\/p>\n

Well, I try emerge @preserve-rebuild without mplayer2 and now I get this for \/vlc-2.1.2:<\/p>\n

checking for AVCODEC… yes<\/em>
\n configure: error: libavcodec versions 56 and later are not supported yet.<\/em><\/p>\n

Yep, vlc is giving me issues. \u00a0Now I am on the slippery slide of getting off the Gentoo path, so I up the stakes, I unmask\u00a0media-video\/vlc-2.1.5-r1 and try again. \u00a0You might ask why jump up to 2.15-r1 and I would reply that if I am going to blow things up badly then I might as well go big.<\/p>\n

Great, now k3b errors on compile! \u00a0Unmask\u00a0k3b-2.0.3-r1 and emerge without problems. \u00a0Okay, so where am I now? \u00a0Yep, back to this mplayer2 issue:<\/p>\n

libmpdemux\/demuxer.c:48:2: error: #error MP_INPUT_BUFFER_PADDING_SIZE is too small!<\/em>
\n #error MP_INPUT_BUFFER_PADDING_SIZE is too small!<\/em><\/p>\n

I don’t feel like going to battle for mplayer because I only use vlc or others, so a quick:<\/p>\n

equery d mplayer2<\/p>\n

results in:<\/p>\n

\u00a0 * These packages depend on mplayer2:<\/em>
\nmedia-video\/smplayer-14.9.0-r1 (media-video\/mplayer2[libass,png,X])<\/em><\/p>\n

So:<\/p>\n

emerge –unmerge mplayer2 smplayer\u00a0<\/em><\/p>\n

Now what was I doing? \u00a0Yep, OCRFeeder install. \u00a0Well, that went okay finally, but OCR engines have to be installed. \u00a0I installed gocr, ocrad, cuneiform<\/a>, and tesseract<\/a>. \u00a0OCRFeeder lets the user select the engine.<\/p>\n

Another day in Gentoo world ….<\/p>\n
