> Hi,I've been trying to capture an RTMP stream and save it as mp4. I'm usingsplitmuxsink for mp4 creation. Pipeline as follows:rtmpsrc location='rtmp://127.0.0.1:1935 live=1' do-timestamp=true !

rtmpsrc is not a live source, hence do-timestamp not being an appropriate property for this element. This was discussed recently in another thread, this property is a "foot gun" to follow the wording trends these days. You can cheat a little, and turn this into a live pipeline (hence ensuring you have a clock), using "identity sync=1" right after it. I haven't tested, but I believe it should work.
