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.

I see, that’s the switch to CBR index.

Muxer uses ….32.30.01 UID which is High 422 Intra according to specs:

urn:smpte:ul:060e2b34.0401010a.04010202.01323001	LEAF	H.264/MPEG-4 AVC High 422 Intra Profile Unconstrained Coding	Identifies H.264/MPEG-4 AVC High 422 Intra Profile Unconstrained Coding

So I’m not sure what media info is doing here.

I looked a little deeper into MediaInfo code. If the avc subdescriptor is
used, MediaInfo expects that in addition to profile and level, the profile
constraint is also set for intra coding.
Other MXF muxer, e.g. bmxlib, also set the profile constraint in the avc
subdescriptor.

Thomas
