Description

Concatenates streams together to one continous stream.

All streams but the current one are blocked until the current one finished with GST_EVENT_EOS. Then the next stream is enabled, while keeping the running time continous for GST_FORMAT_TIME segments or keeping the segment continous for GST_FORMAT_BYTES segments.

Streams are switched in the order in which the sinkpads were requested.

By default, the stream segment's base values are adjusted to ensure the segment transitions between streams are continuous. In some cases, it may be desirable to turn off these adjustments (for example, because another downstream element like a streamsynchronizer adjusts the base values on its own). The adjust-base property can be used for this purpose.

Example launch line

1
gst-launch-1.0 concat name=c ! xvimagesink  videotestsrc num-buffers=100 ! c.   videotestsrc num-buffers=100 pattern=ball ! c.

Plays two video streams one after another.
