java xsd xml validation woe

org.xml.sax.SAXParseException; systemId: file:/…/gedcomx.xsd; lineNumber: 622; columnNumber: 62; cos-nonambig: WC[##any] and “”:link (or elements from their substitution group) violate “Unique Particle Attribution”. During validation against this schema, ambiguity would be created for those two particles.

meant “validate with saxparser instead” (wait what???)

ffmpeg cross compile woe

meant this

ffmpeg configure how to allow auto detection of codec without file types

ffmpeg can read png/bmp but can’t “auto detect them from unknown file type extension”

blank.pxxnxxgxx: Invalid data found when processing input

or with -f image2

Decoder (codec none) not found for input stream #0:0

meant add this to configure (after previously –disable-everything)

one of these fixed it:

–enable-demuxer=image2pipe –enable-demuxer=image_png_pipe –enable-demuxer=image_bmp_pipe –enable-demuxer=image_jpeg_pipe

ffmpeg woe

some interesting woze after doing ffmpeg ./configure –disable-everything then adding back in what I needed/wanted:



blank.png: Protocol not found
Did you mean file:blank.png?


meant configure with –enable-protocols
