This is gstreamer version 1.14.4 and ubuntu version 4.9.140-tegra using bash shell all running on Jetson Nano dev system. I tried various escape methods and none worked. The following has double quotes with quotes inside the sink definition and doesn't work. gst-launch-1.0 playbin uri=<a class="moz-txt-link-freetext" href="file:///home/tom/Videos/UHD_demo_Nature.mp4" moz-do-not-send="true">file:///home/tom/Videos/UHD_demo_Nature.mp4</a> sink="glupload ! glshader fragment="\"<code>ca t testfrag.frag</code>\"" ! glimagesinkelement" I assume it's an escape sequence issue, I tried bunch of ways to escape but I would rather not bias anyone looking at this problem. The opengl fragment is correct and works using a simple command line example: gst-launch-1.0 videotestsrc ! glupload ! glshader fragment="\"<code>cat testfrag.frag</code>\"" ! glimagesink Any ideas is this a command shell issue or gstreamer issue I need to correct concerning double quotes. Here is the fragment: #version 100 #ifdef GL_ES precision mediump float; #endif varying vec2 v_texcoord; uniform sampler2D tex; uniform float time; uniform float width; uniform float height; vec4 myColor; void main () { <pre><code> myColor = texture2D( tex, v_texcoord ); gl_FragColor = myColor; gl_FragColor.r = myColor.b; gl_FragColor.b = myColor.r; </code></pre> } When I run the command line I get the following error: WARNING: erroneous pipeline: no element "100" Thanks in advance.
