the same problem with "avid_ntsc_progressive.avi"

comment:2 Changed 7 years ago by richardpl

Does same happens with other/normal resolutions?

comment:3 Changed 7 years ago by ami_stuff

check ticket #162 for normal mjpeg mode, but this is a different problem (wrong resolution reported by ffmpeg).

I'm not sure, but I think raw "1:1" mode worked ok in the past (without black bar).

  • Component changed from undetermined to avcodec
  • Keywords AVRn added
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from unspecified to git-master

Related to #970.

Actually this is more of duplicate of ticket #162 (even if it should be easier to solve).
The AVRn codecs seem to store the overscan area along with it the proper image data, so if you look at it in e.g. GIMP you will see that the video actually is 720x592 and not like the headers claim 720x576.
