I am receiving a multicast udp ts stream in android using tutorial 3, this is my pipeline
data->pipeline = gst_parse_launch("udpsrc port=1235 multicast-group=227.2.2.2 ! decodebin ! autovideosink sync=false", &error); The video player works well but if send the application to background (Click home button, or another app appears on foreground) and the go back to the app android recreates the surfaceview but then gstreamer throws an this error: streaming stopped, reason not-linked (-1) and the stream cannot be played again.

Re: Streaming stopped, Pad is not linked after Android recreates surfaceview

I have zero experience with android development, so I maigth be missing something. However, what I presume is happening is that the decodebin is detecting the multicast as a new stream, it is recalculating the decoding pipeline and creating a new pad for outputting the data. There is no logic to handle the new pad so the pipeline fails complaining it is unlinked. This is especially the case if you are using something like rtp, which has a session manager and there is no predefined token for the session it should be monitoring. You need to monitor the decode bin for the new-pad event. When a new pad becomes available you need to link it to the sink so you can continue streaming. You also need to handle the old pad, either returning it to the bin or connecting it to a fakesink or a pad that will handle any incoming data. It might be better to extract the rtpbin from the decodebin, or whatever session manager is performing the change in your case, to ensure that you can handle the pads correctly for your case. Another small note is that you shouldn't use sync=false. If your stream is dropping frames it is because it is not calculating the required latency correctly. You can either use the "ts-offset" parameter of the sink to add some latency to the calculated one or set the entire pipeline latency using gst_pipeline_set_latency. Also, if you are not handling the latency messages from the bus you can have similar results. You need to call a gst_bin_recalculate_latency to correct the latency calculation when there are changes in the pipeline, which can happen when using decodebin.On Fri, Feb 3, 2017 at 12:53 AM, adr0id <[hidden email]> wrote: I am receiving a multicast udp ts stream in android using tutorial 3, this is |
