Re: [osg-users] osgmovie - ffmpeg or Gstreamer
Good that you have something working. Makes it easier to try things. Forgot to mention, but enabling some GStreamer degug options might help. Try to "set GST_DEBUG=5" on CLI before launching osgmovie. Miight give you some insight as to why things don't work. This page is a must read: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gst-running.html Using decodebin has the advantage, on paper, to be able to play any video supported by GStreamer. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=74182#74182 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgmovie - ffmpeg or Gstreamer
Hi Filippe,
after some hours of disperate fighting against gstreamer pipeline, here the
pipeline that works for play video and audio (mp4) in a correct way:
Code:
gchar *string = g_strdup_printf("filesrc location=%s ! qtdemux name=demux
demux.video_0 ! queue ! video/x-h264 ! avdec_h264 ! videoconvert !
video/x-raw,format=RGB ! appsink name=sink emit-signals=true demux.audio_0 !
queue! faad ! audioconvert ! audioresample ! autoaudiosink ",
filename.c_str());
I don't know if it is the right way, but it works for me. I modified
GStreamerImageStream.cpp , GStreamerImageStream::open method.
Thank you!
Cheers,
Andrea

Hi Filippe, another detail i forgot to write in the previous post. After OSGMOVIE execution, OSGDB::ReaderWriter returns FILE_NOT_HANDLED Thank you!

Re: [osg-users] osgmovie - ffmpeg or Gstreamer
Hi Filippe, thank you for your reply. Well, i tried front slash string for osgMovie parameters: C:/SVILUPPO/CommonData/Movie/surf360converted.ogg --texture2D --interactive --audio but _width and _height attribute in GStreamerImageStream::open method, continue to be equal to zero, and so this method returns false. After that, i tried to call the same pipeline dynamically created in the open method, with gst_launch-1.0: gst-launch-1.0.exe filesrc location=C:/SVILUPPO/CommonData/Movie/surf360converted.ogg ! decodebin name=deco deco. ! queue ! videoconvert ! video/x-raw,format=RGB ! appsink name=sink emit-signals=true I get the following console message: C:\gstreamer\1.0\x86_64\bin>gst-launch-1.0.exe filesrc location=C:/SVILUPPO/CommonData/Movie/surf360converted.ogg ! decodebin name=deco deco. ! queue ! videoconvert ! video/x-raw,format=RGB ! appsink name=sink emit-signals=true Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock and nothing happens. Then i substitued appsink name=sink with autovideosink, but in this case i get the following error message: C:\gstreamer\1.0\x86_64\bin>gst-launch-1.0.exe filesrc location=C:/SVILUPPO/CommonData/Movie/surf360converted.ogg ! decodebin name=deco deco. ! queue ! videoconvert ! video/x-raw,format=RGB ! autovideosink emit-signals=true Setting pipeline to PAUSED ... Pipeline is PREROLLING ... WARNING: from element /GstPipeline:pipeline0/GstDecodeBin:deco: Delayed linking failed. Additional debug info: ./grammar.y(510): gst_parse_no_more_pads (): /GstPipeline:pipeline0/GstDecodeBin:deco: failed delayed linking some pad of GstDecodeBin named deco to some pad of GstQueue named queue0 ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:deco/GstOggDemux:oggdemux0: Internal data stream error. Additional debug info: gstoggdemux.c(4936): gst_ogg_demux_loop (): /GstPipeline:pipeline0/GstDecodeBin:deco/GstOggDemux:oggdemux0: streaming stopped, reason not-linked (-1) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline .. And last, i removed video/x-raw,format=RGB getting the following command line: gst-launch-1.0.exe filesrc location=C:/SVILUPPO/CommonData/Movie/surf360converted.ogg ! decodebin name=deco deco. ! queue ! videoconvert ! autovideosink emit-signals=true In this case video starts correctly. So, i tried to change the pipeline in GStreamerImageStream::open with the following: filesrc location=C:/SVILUPPO/CommonData/Movie/surf360converted.ogg ! decodebin name=deco deco. ! queue ! videoconvert ! appsink name=sink emit-signals=true But, i continue to get _width and _height equal to zero, and the open method returns false and no video play.

Re: [osg-users] osgmovie - ffmpeg or Gstreamer
I would try to call osgmovie with forward slashes in the file name.
Your test with gst-launch uses forward slashes and works.
And GStreamerImageStream constructs a similar pipeline (using the same filesrc
element) :
gchar *string = g_strdup_printf("filesrc location=%s ! \
decodebin name=deco \
deco. ! queue ! videoconvert ! video/x-raw,format=RGB ! appsink
name=sink emit-signals=true \
%s", filename.c_str(), audio_pipe);

Re: [osg-users] osgmovie - ffmpeg or Gstreamer
Hi, I use GStreamer to play movies within an OSG and it works fine on Windows. The errors you get seem to indicate that your video file cannot be located. So I am a bit surprised you were able to debug anything as video playback should not even satart. What exact command line did you use to test with osgmovie? I'll try to reproduce your error.

[osg-users] osgmovie - ffmpeg or Gstreamer
Dear All, i would like to share with you some issues concerning play video streaming (with audio) starting from osgmovie. I already used ffmpeg plugin with sdl2, but i get different results with the same application (osgmovie) and the same video (.mp4 extension) on different PCs: - HP Z440 with geforce gtx 1080 - Alianware (laptop) with 2 graphic board (nvidia geforce gtx 1080 and an internal intel board) On HP, i play video correctly. On laptop video is playing faster. Is it depends on video board configurations? Is there some parameters i can configure on osg:iamgestreamer class or FFmpegImageStream, in order to force frame rate to a specific value? Furthermore, i'm looking for another plugin to use with openscenegraph (i'm using openscenegraph 3.5.3 on windows 10) as alternative of ffmpeg. I see that cmake accepts gstreamer, so i downloaded gstreamer development 1.0. Cmake works correctly, but no change appears on solution sln. I don't know how to proceed to use gstreamer with osgmovie to test some video and audio streaming. Is there any example about? Thank you in advance Kind regards Andrea ... Thank you!
