The Gapless Playback example will run a video from start to end sequentially in an infinite loop. To do so, it will wait for the file playback to finish before rewinding to the beginning of the file and restarting playback. The end of the playback is detected by polling the pipeline bus for the End Of Stream (EOS) message, which is posted by the Filesrc element when all the content has been read. The rewinding is done by sending a Seek event to the pipeline, which effectively restarts the pipeline.
Example
The following example is a bash script that demonstrates the simple gapless playback.
#!/bin/bash # Absolute path to the video location VIDEO=$1 gstd-client pipeline_create p playbin uri=file://$VIDEO # Listen to the EOS messages gstd-client bus_filter eos gstd-client pipeline_play p # Wait for the message to perform seek while true; do gstd-client bus_read p gstd-client event_seek 1.0 done
