Hi,
I am trying to do gapless playback using playbin3 with decklinksink elements. Starting the playback with a mp4 file and second in the list is a mkv file. Changing the uri in “about-to-finish” callback function. After switching to second uri (mkv file’s uri), only audio is coming. There is no video in the output.
Did testing with some more combination and the result is attached.
There is no issue when I do a instant uri change.
It would be very helpful if somebody help me on this issue.
