Analyze mpeg headers - mini QC example workflow
Posted: Fri Jul 16, 2021 3:37 pm
I guess not only interesting for @Silicon who PM'ed me about analyzing mpeg2 headers for a specific error,
here some example job that checks if vbv_delay values below 10.000 were found. If there were such values, the workflow will fail at the end.
I am not 100% sure if this is a real MUST for xdcam but in videos that worked for Silicon, all vbv_delay values were larger than 50.000, so i guess the check should be fine.
This could be a starting point for doing very deep QC checks and see if the mpeg2 stream for example is XDCAM compatible (or check other standards).
@Silicon, i believe you can use this in forward production to detect if a video is affected (without import to mam), so you get your logs from the video server and can send them to the vendor.
