DRA72XEVM: Playing a video file in Qt crashes the whole program

Sam George39

Part Number: DRA72XEVM

Hi there,

I have a sample qt app that plays an h264/mp4 video. But when i tried to play video, the app crashes throwing the following error:

root@dra7xx-evm:~/mplayer# ./mplayer
No such plugin for spec "Auto"
Using Wayland-EGL
wlpvr: PVR Services Initialised

(mplayer:2215): GStreamer-CRITICAL **: gst_buffer_peek_memory: assertion 'GST_IS_BUFFER (buffer)' failed

** (mplayer:2215): CRITICAL **: gst_fd_memory_get_fd: assertion 'mem != NULL' failed
Segmentation fault (core dumped)

Here is the code:

import QtQuick 2.3
import QtQuick.Window 2.2
import QtMultimedia 5.5

Window {
    visible: true
    height: 480
    width: 640

    MediaPlayer {
        id: mediaplayer
        source: "file:///Video/NonCritical/06082018/hi.mp4"
    }

    VideoOutput {
        source: mediaplayer
    }

    MouseArea {
        id: playArea
        anchors.fill: parent
        onPressed: mediaplayer.play();
    }

}

Any solution?

Hi Sam,
Does the playback work fine with playbin? Do you have any idea of the underlying gstreamer pipeline executed when Qt app is run?
Does it happen for all streams?
waylandsink by default supports only desktop-shell . Is weston configured for ivi-shell?

The playback works fine with gst-launch.
No i have no i idea of the underlying gstreamer pipeline.
yes it happens for all streams.
No, weston is not configured for ivi-shell and futhermore we are perfectly running qt apps with live-streaming on the device.

Sam,
I tried with this QT application available in PSDKLA3.04 filesystem to playback a small stream, it is working .

/usr/share/qt5/examples/multimedia/video/qmlvideo/qmlvideo

Can you share the binary for your qT application to reproduce the issue?

hi Ram,

The above mentioned app also throws the same error. Moreover we tried to run some sample videos in /usr/share/ti/video. Videos with .264 and .m2v types run smoothly but the files with other type crashes with same error.

Hi Sam,
Can you confirm if gstvpe is enabled in this case? You can check this by adding this statement
export GST_DEBUG=vpe:6
before executing the playback. If you are seeing QBUF and DQBUF are happening, it confirms vpe is used and there are some issues with gst-vpe in PSDKLA3.04, you need to apply these changes on gst vpe

Apply these changes from 3 commits and rebuild gst-vpe and copu the libgstvpe.so to /usr/lib/gstreamer-1.0 and check if the iss

Yes there are QBUF and DQBUF in the output. I have attached the copy of the output.

OK,

Apply these 3 commits. Your issue should get resolved.

The second commit was for same error with trick-play.

Thanks Ram,

It solved the playback issue. But at times the app crashes with the following error

It occurs once in every 20-30 time.

Hi Sam,
When this issue happens , can you check the dmesg and look for
"omapdrm omapdrm.0: could not remap"
if this is observed, then the 128MB TILER is not sufficient.

Is this happening for all type of streams?

HI Sam,
Did you apply all three patches? First patch with commit-id a1fe1f3e3ae0582a4f84ae8fa7ca052fff2e9f76
should resolve your issue of dce_errors.
