For RP2027 Class 100 1080/50i I still get the error: frame size does not
match index unit size, 568832 != 0
I used the following command:
ffmpeg -f lavfi -i testsrc=size=1920x1080:rate=50 -vf interlace -c:v
libx264 -pix_fmt yuv422p10 -flags +ildct+ilme -avcintra-class 100
-color_primaries bt709 -color_trc bt709 -colorspace bt709 -x264-params
overscan="crop":videoformat="component":fps=25/1:interlaced=1:tff=1:force-cfr=1
-t 1 avci.mxf
Also I encoded AVC High 422 Intra with the following command:
ffmpeg lavfi -i testsrc=size=1920x1080:rate=50 -c:v libx264 -pix_fmt
yuv422p -x264-params keyint=1 -t 1 avc.mxf
Without your patch MediaInfo shows Format profile: High 4:2:2 Intra@L4.2.
With your patch MediaInfo shows Format profile: High 4:2:2@L4.2 and
Format_Profile_Original: High 4:2:2 Intra@L4.2.
According to the MediaInfo documentation, the additional
"Format_Profile_Original" is shown when two format profile infomations are
found that do not match.

Thomas
