It's empty frame...

log

Oh, ok, It works fine now with QGraphicsVideoItem.
Thanks for your support

from qtavplayer.

#483

from qtavplayer.

Thanks for the report.

Does it mean that frame() returns nullptr there?

Could you test
https://github.com/valbok/QtAVPlayer/blob/master/src/QtAVPlayer/qavhwdevice_d3d11.cpp#L324

if (!frame().frame())
    return {};

from qtavplayer.

I tried your test but frame() is not nullptr,
The problem occurred on this line:
return QLatin1String(av_pix_fmt_desc_get(QAVVideoFrame::format())->name);
And I saw that QAVVideoFrame::format() return -1 at that.

I tried 2 simillar samples with QVideoWidget and QGraphicsVideoItem, It both contains a videoSink.
The sample with QVideoWidget worked fine, But the sample with QGraphicsVideoItem crashed on the line above after call to play()

from qtavplayer.

could you qDebug() << frame().frame()->format; ?

Is it -1?

from qtavplayer.

Yes, It prints -1, but with the QVideoWidget, It prints 172.
I think It has some difference between QVideoSink in QVideoWidget and in QGraphicsVideoItem. But I'm not sure

Note: I used the same rtsp link with both case

from qtavplayer.

Forgot to ask, static_cast<bool>(frame()) should be false there?

Meant that the frame is invalid and should be skipped

from qtavplayer.

Sorry, I dont know where is the "static_cast(frame())" you mentioned
I'm using Qt 6.6.2 which has a defined for handling

from qtavplayer.

meant to check like
if (!frame()) qDebug() <<"empty frame";

from qtavplayer.

so could you please just skip it?

if (!frame())
    return {};

And check if some correct video frames will be sent? Also could you provide std output? Maybe it could not find a codec...
