I have just checked in a similar patch, without the while loop, and always enabled (it should be the default behaviour).

However, I don’t understand why you need this. First of all, you should apply the same offset to DTS and PTS, because most elementary streams do not have a DTS so only the video would be impacted. But also, the resulting streams would be totally non-compliant with the TS buffering model.

Best,
