 Summary of the bug:
 When encoding using libx264 in 4:2:2 10 Bit (Pixformat yuv422p10le) you
 can create for example MP4 or TS output with no problem. But output to MOV
 creates a Quicktime Movie that is flagged as AVC-Intra (CodecID ai12) and
 doesn't play properly, because it is H.264 internally of course.
 But we need that MOV-Container because its the only format that supports
 uncompressed audio streams.

 At first we thougt Quicktime-MOVs dont support yuv422p10le - but for
 example the Panasonic GH5 camera writes exactly that format and it works
 with different editing systems.
 Additionaly we tried to pipe the yuv422p10le-MP4 through ffmbc (just copy
 video and audio) and let ffmbc create a MOV out of that. That works too.

 So should ffmpeg be able to create that kind of MOV too?


 How to reproduce:

 ffmpeg.exe -i source.mov -c:v libx264 -crf 18 -pix_fmt yuv422p10le -preset
 medium -tune film -level 41 -keyint_min 25 -g 50 -qmin 3 -qmax 51 -qdiff 4
 -sn -n output.MOV

 This creates that strange AVC-Intra MOV.
 When changing File-Extension to MP4 or TS everything is fine.


 ffmpeg version N-93075-gb429c86d84
 built with gcc 8.2.1 (GCC) 20181201

 but we tried even the 4.1.1 Release with same problem.
