Hi, how can I de-jitter an udp IP multicast stream as input and take corrected IP multicast output using tsp or any other option in tsduck? Please advise. Thanks - MKS

Hi,

As discussed in #587, TSDuck is probably not the best tool to do this.

If the jitter is completely insane, you may reduce it using the plugin regulate with extremely fine-tuned buffering parameters.

However, de-jittering should be an extremely precise operation which needs a specialized tool if you want to reach a millisecond precision. TSDuck is a generic and flexible framework which does too many things to be that precise on the realtime side.

Thanks @lelegard , will try to use "regulate" plugin. In this plugin, the --pid-pcr value is in decimal or hex? Thanks-MKS

lelegard commented 4 years ago

With TSDuck, all integer values can be decimal or hex, just use "0x" to prefix hex values. See section 3.1.2 in the user's guide.

ok thanks. Just to mention more into the issue, I want to smoothen or de-jitter the following udp MPEG-TS stream as seen on the analyzer. image

mks75 commented 4 years ago

although this is a CBR stream but doesn't look smooth. How can this be made smooth? Will "regulate" plugin help here? Please advise.
