Streaming TS vs PS: blocky frames with TS?

[JohnPeterson]

When comparing streaming with the TS and PS muxer

Code: Select all

cvlc ${v} -vvv --sout "#duplicate{dst=standard{access=http,mux=ts,dst=:8554},dst=standard{access=http,mux=ps,dst=:8555}} 2>&1|tee server.log"

the lost frames are similar but TS give fairly much blocky frames (a batch of blocky frames every ten seconds or so) which PS hasn't.

Here are the logs for the server and the two clients. Here is a screencap with the blocky TS on the left and PS on the right.

The artifacts seem to always occur on the same frames. The artifacts seem to correlate with this server message, but it could be a coincidence.

[0x7faad40022c8] mux_ts mux warning: packet with too strange dts (dts=174025600874,old=174025601290,pcr=174025601290)

Latency is low and throughput high since its on the same PC (the same thing occurs when streaming in the same Windows environment as when streaming from a VMware Ubuntu guest), and also tested over a gigabit LAN. It shouldn't be a specific setting either since the Ubuntu cvlc that's streaming is the dpkg version with unmodified settings, and it's tested on different clients on the LAN, some with default settings.

It's the same when using RTSP instead of HTTP.

I'm wondering if anyone else experience that TS give more blocky frames than PS.
