the same problem with "avid_ntsc_progressive.avi"

​http://roundup.libav.org/file710/avid_ntsc.rar

[Elon Musk]

Does same happens with other/normal resolutions?

[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).

[Carl Eugen Hoyos]

Related to #970.

[reimar]

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.
