<div dir="ltr">Hi, Stefan:     I think your pipeline is using GstSystemClock because you mentioned the source is a live element. If it is, the clock will keep increasing even if the pipeline is paused. This makes the timestamp noncontinuous. To generate a continuous timestamp, I think you can try to use the clock provided by your sink elements. Maybe this is not easy because the live element is different with other source elements.

Assume an applications that shows video from a camera. When you click a button it records to file, allowing to pause and unpause in between. The recorded file should have a continuous stream. If I don't do any special casing this is not the case. 1) When I playback the recorded file, I have an initial pause before video start (if I pressed record after two seconds, the video will start after two seconds). 2) If I pause in between, also in the playback there is a pause. Right now I work around with a pad probe that looks at disconts to aggregate a time_stamp_offset and correct all incoming buffers by subtracting that. It works but probably is not the right way. I believe this involves the use of segments, but I am not sure how. Also both behaviors might be valid (having a sparse and having a continuous stream). So the application would somehow be involved to select the desired behavior. Any comments?
