I don't know how and where to plug another filescr and textoverlay for this matter. <div class="gmail_quote">2011/11/26 Rossana Guerra <<a href="mailto:guerra.rossana@gmail.com">guerra.rossana@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hello, tanks for your response, I'm aware of GstParse, but I need a 'customization' of this pipeline actually, and doing it by code, that's why I asked. I need to add subtitles and other time-based elements to an avi file. This is my actual pipeline, mad ---- ffdec_mpeg4 ----queue-----alsasink //audio part filescr---avidemux ---- queue---autovideosink //video part Thanks Rossana<div class="HOEnZb"><div class="h5"> <div class="gmail_quote">2011/11/26 Sean McNamara <<a href="mailto:smcnam@gmail.com" target="_blank">smcnam@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, <div><div> On Sat, Nov 26, 2011 at 8:13 PM, Rossana Guerra <<a href="mailto:guerra.rossana@gmail.com" target="_blank">guerra.rossana@gmail.com</a>> wrote: > Hello everyone, I need to pass this command line with some nuances, to code > (c/c++): > gst-launch textoverlay name=overlay ! ffmpegcolorspace ! videoscale ! > autovideosink filesrc location=movie.avi ! decodebin2 ! ffmpegcolorspace ! > overlay.video_sink filesrc location=movie.srt ! subparse ! overlay.text_sink > > How it could be? the linking issues mainly, I can't get how to to with 2 > filescr, one for the avi and the other one for the .srt. </div></div>If this pipeline does what you want in gst-launch, just take the pipeline description text and pass it to one of the GstParse functions (depending on how much control you need): <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstParse.html" target="_blank">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstParse.html</a> Unless you need to dynamically add/remove elements from the pipeline at runtime, you should never have to do any manual element linking/unlinking if you use GstParse. You just get a Bin or a Pipeline, set properties as needed, and control the state (paused, playing, etc) depending on what your app is supposed to do.
