I was expecting that I could read, parse and output a TS file synchronously using a pipeline like this: gst-launch-1.0 filesrc location=../Downloads/OC3.demo.ts ! queue ! tsparse ! fakesink sync=1 but what I see is that the pipeline reads the file, parse it and send it to the fakesink as fast as the hardware supports. That is, it does not decode the timestamps in the PES header and send it out synchrosnously although the sync flag has been set. Obviously fakesink is to be replaced by something else like a filesink to a pipe or a udpsink or ..... What is the correct way for GStreamer to playout a TS file synchronously without having to decode and re-encode it? The module decodebin can obviously decode it synchronously. The ts testfile is available from Opencaster a <a href="http://www.avalpa.com/assets/video/OC3.demo.ts" target="_blank">http://www.avalpa.com/assets/video/OC3.demo.ts</a> Best regards Peter MM -------------- next part -------------- An HTML attachment was scrubbed...

This means, split your stream over multiple clocks, hence not synchronization is happening. If you want synchronized playback, keep everything in the same pipeline, or considering using a shared clock. Nicolas -------------- next part -------------- A non-text attachment was scrubbed...

Also for mail notifying of new commits, it looks like: [Diffusion] [Committed] rGSTDEV0cfff156b1d7: validate-utils: simplify _read_builtin () or [Diffusion] [Committed] rGESd7dfcff7459d: timeline: Use a simple GList to track auto transitions So here you can see for what repo that is.
