[FFmpeg-user] AVCIntra50 MXF issue - aspect_ratio_idc

[Christoph Gerstbauer]

Hello,

I am testing AVCIntra 50/100 Flavours of different encoders and I am facing
an Issue with AVCINTRA50.

My checking the MXF Wrapper my testing program MXF Analyzer shows following
error:

"Invalid essence element payload in Generic Container Element with Track
Number 352388352 | 0x15010500 of Essence Container with EssenceStreamID
(BodySID) 1. Reason: constrained: Current AVC file is not compatible with
AVC-Intra constraints.
For Class 50 Specification aspect_ratio_idc must be 255 (Extended_SAR).
Essence analyser: MPEG AVC Video. Essence Container Label:
06.0e.2b.34.04.01.01.0a.0d.01.03.01.02.10.60.01. Terminating essence
parsing while processing Edit Unit number 1."

my used ffmpeg syntax is:
-map 0:v -map 0:a -map 0:a -map_channel 0.1.0:0.1.0 -map_channel
0.1.1:0.2.0 -vf "setfield=tff, fieldorder=tff, setsar=1.33" -c:v libx264 -r
25 -s 1440x1080 -aspect 16:9 -g 1 -b:v 54298k -pix_fmt yuv420p10le -flags

So,
A.) is this maybe just a problem in my syntax and its somehow possible to
set the "aspect_ratio_idc" with an aditional syntax part or
B.) is this a bug/improvement issue for avcintraclass=50 encoding in ffmpeg?
