How does rsync://fate.ffmpeg.org/fate-suite/zerocodec/sample-zeco.avi play with the original codec?

comment:3 follow-up: Changed 4 years ago by ami_stuff

this one plays correctly, so no need to fix anything. mine should be encoded as rgb24 (at least I selected such color depth for output in virtualdub), but i'm not sure which pixel formats are really supported by zerocodec

Replying to ami_stuff:

I messed up something, here is a correction:

ffplay:

sample-zeco.avi - ok
zerocodec.avi - upside-down

wmp + zerocodec or virtualdub + zerocodec:

sample-zeco.avi - upside-down
zerocodec.avi - ok

remove ffzerocodec and add this to codecs.conf for test with mplayer:

videocodec zerocodec
  info "ZeroCodec"
  status working
  fourcc ZECO
  driver vfw
  dll "zerocodec.dll"
  out BGR24
