Mar 28, 2012 · Description. GstMemory is a lightweight refcounted object that wraps a region of memory. They are typically used to manage the data of a GstBuffer.. A GstMemory object has an allocated region of memory of maxsize.
Dec 16, 2020 · FileSink (std::ostream &out) FileSink (const char *filename, bool binary=true) out is an existing standard ostream. filename is the name of a file. The FileSink will open the file as an ostream and truncate it if it exists. binary is passed to the underlying ostream. When the library opens the stream, it is opened with the ios::trunc flag.

Jul 03, 2018 · While gstreamer-launch is able to push video to v4l2loopback devices better than ffmpeg does, frames read from the v4l2loopback devices are sometimes corrupted. Therefore I am looking for other possibilities to split the input devices in some way in order to record them and use them as sources in OBS at the same time.

Apr 12, 2013 · I think they will eventually HAVE to integrate it with raspian jessie at some point or the other. gst-omx is already part of gstreamer-1.x. The logic of staying with gstreamer-0.10.x series is absurd for the raspi, because of the lack of OpenMAX IL support and hence the hardware encoder goodies. May 24, 2013 at 12:52 AM

GStreamer is a low-level video system for Linux (like a libre version of QuickTime or DirectShow). GStreamer can be tested / triggered / hacked with from the command line using the gst-launch and gst-inspect programs. GStreamer can also be programmed via scripting languages. For instance, there's a nice connection library to use it from Python.
filesink writes the results back to disk; Unfortunately it turns out the mp4 muxer does not work as intended. Either that or all the sound encoders are broken. The resulting file plays fine in mplayer but any attempt to use it with gstreamer gives you smooth video with broken audio (one sample per half a second).
