  • Component changed from undetermined to avcodec
  • Keywords targa added
  • Reproduced by developer set
  • Status changed from new to open
  • Summary changed from targs: support interlaced mode to targa: support interleaved mode
  • Version changed from unspecified to git-master

This (in MPlayer and Targa specification speak "interleaved") mode can be detected with (flags & 0x40).

Could you upload a "4-pass interlaced" (actually "four way interleaving") sample?
