Playing multi stream containers gaplessly

[Vladislavs Zaluckis]

Hi Tim,

After sleeping on the example app for some time, I don't get why it needs to be so complicated. Could you (or anybody) explain, why can't I just use concat element in each of the streams to stitch the adjacent items? Say I prepare (preroll) the next item and connect its video and audio streams to corresponding concat elements. Then concat will do the rest -- switch to the next item as soon as the current one ends with EOS, each in its own stream. Don't you think it could work?

Thank you so much!

What I am trying to do is to play two container files with multiple streams inside (I take one video and just one audio) one after another without a gap. I am using filesrc/decodebin for input, then some simple processing, then playing to autosinks. As one file ends, I am relinking the pipeline dynamically, following the procedure described in the app dev guide. So far so good, but when I try to run the actual production-like pipeline, it gets stuck on EOS processing. The "production" pipeline is encoding to x264/AAC, then muxing to MPEGTS, then packetizing using RTP, then sending to UDP.
