QMediaPlayer - Errors, 'No decoder Available'
mjv817 last edited by mjv817
I am working on a sample GUI and trying to get a video to play in a dock. I have getting some errors though when I run the code. I box appears when I run the program, but it was only a black screen.
The error I am getting says 'No decoder Available for 'video/quicktime variant=string-iso'
I have installed GStreamer and VLC as well..not sure if I am missing certain codecs or how to get QT to use them.
Part of my code below.
playlist->addMedia(QUrl::fromLocalFile("/home/mjv817/dockingProject/newConvert.mp4")); playlist->setCurrentIndex(1); player = new QMediaPlayer; player->setPlaylist(playlist); videoWidget = new QVideoWidget; player->setVideoOutput(videoWidget); videoWidget->show(); player->play();
Ok I made some changes to my code and now receiving the following error.
'Your GStreamer installation is missing a plug-in'
I am Fedora 24 and tried installing the following through the terminal, but received an error.
No package gstreamer0.10-ffmpeg available.
Still not sure what/how to install the proper plugins.
You should check your distribution's package manager and install all of GStreamer's plugins.
Ok just double checked and made sure I had all of the Gstream plugins. I was missing the "good" plugin and now have good/ugly/core gstream packages installed.
I ran the program again and received a different error.
'GStreamer encountered a general stream error.'
Hmm getting closer?!?! lol been trying to get this to run for a few hours now!
Which version of Qt are you using ?
Desktop QT 5.7.0 - GCC 64 bit
Then please call
lddon Qt's gstreamer plugin to ensure that it's linked against gstreamer 0.10
Sorry for the noob question, but can you explain how to use this command?
Would I call "ldd 'applicationName.cpp', or find the location of gstreamer?
lddshould be called either on a dynamic library or an application executable.
So find the plugin in your Qt install under
Qt_VERSION_NUMBER/COMPILER/plugins/mediaservice/and the call
lddon its content.
