 > Okay. Got a fix in
 https://github.com/gpac/gpac/commit/fe02e73f7e1e6caf74a826bdd64b49eff1e5bdc5
 that fixes SAP 2 in both hevc samples, only for gpac.exe file.hevc
 inspect:deep
 Can it help somehow to fix ffmpeg? Usually I don't use gpac. Sometimes
 mp4box crashes on huge files in the middle of process. But I expected to
 get ffmpeg fixed.

 > BTW, do you have original mp4 files or whatever Sony uses? I need to
 look at how they signal editlist and sdtp box.

 Sure
 http://slydiman.me/ffmpeg/sony_hevc_yuv422p10le_4k.mp4

 I don't see any sdtp. Note SONY uses MXF-like metadata and fragmented old
 kkad metadata inside with SPS and many PPS. Note I can decode these
 metadata. I have not seen specs of these metadata in the public domain.
