Gstreamer question

is flag

Recently I was learning gstreamer, and I have two questions.

I.

  • I followed the basic tutorials about the section "HelloWorld". I git clone the code and use this command on ubuntu: gcc basic-tutorial-1.c -o basic-tutorial-1 pkg-config --cflags --libs gstreamer-1.0`
  • and then run ./basic-tutorial-1
  • returns (basic-tutorial-1:14500): ERROR : 10:43:49.783: An error occurred! Rerun with the GST_DEBUG=*:WARN environment variable set. for more details. Trace/breakpoint trap (core dumped)

I guess the URL playbin uri=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm could not connect, maybe I should change the URL?

II.

  • I followed Basic Tutorial 3: Dynamic pipelines, the tutorial says it will see the video just like HelloWorld, but the shell returns Not all elements could be created.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
