appimage alpha2-TEST-20180311 no video output

[giacomo]

when I try to play a video I get a white window, this is the message from the terminal:

Video screen: 0 , geometry: QRect(0,0 0x0)
qrc:/VideoContext.qml:21:1: module "QtMultimedia" is not installed

I've qlc+4 installed and the same file plays as normal.

Distro ?

Clearly, a dependency is missing, but to find the cause you need to ldd each QtMultimedia library in the bundle until you find the broken one.

Try this:

Code: Select all

./QLC+_5.0.0_alpha2-TEST-20180311-x86_64.AppImage --appimage-extract
cd squashfs-root/usr/lib
ldd libQt5Multimedia.so.5
ldd libQt5MultimediaWidgets.so.5
ldd qt5/plugins/mediaservice/libgstmediaplayer.so

One of those should report "not found".
Please consider that recent Qt versions require GStreamer 1.x

[mcallegari]

Disregard the previous one. Seems like another piece was missing on my end.
Please try the bundle I've just uploaded:
QLC+_5.0.0_alpha2-TEST-20180319-x86_64.AppImage

it's working now.

I've just noticed that it's possible to change the rotation parameters while playing the media, it would be fantastic to control the position and rotation with a widget in the Virtual Console, allowing one to manipulate live the media.
This rise to me a curiosity: are you considering the possibility to play several media together or is it too complicate for the moment?
Thanks, the more I try the more I like the new QLC+5.

Good. As you can see (resuming your question "is it possible to have it not to crash"), this is one of the "beauty" of adopting QML. It's like JavaScript. It never crashes, even if there are missing pieces or incorrect code. In this case QLC+ 4 would have crashed.

I've just noticed that it's possible to change the rotation parameters while playing the media, it would be fantastic to control the position and rotation with a widget in the Virtual Console, allowing one to manipulate live the media.

This is feasible indeed and it's actually a good idea. One thing I haven't talked about is the "new" Adjust mode of VC Sliders. They can control any property exposed by a Function. I had EFX parameters in mind (it's been asked a lot of times) but exposing video geomety controls should be trivial at this point.

This rise to me a curiosity: are you considering the possibility to play several media together or is it too complicate for the moment?

See video 3.1
The only limitation is determined by the hardware you're using, not QLC+

hey Massimo, we are close to have a media server now!
I've tried with 2 media in a collection and now I understand how the order works with the alpha channel, it's becoming interesting...
I'm waiting for the fade slider :)

For me, the full screen and custom geometry works for video files,
instead when I play pictures - I tested with png files - I can't play them in full screen with a custom geometry: whatever resolution I select I get a black screen and
in the terminal I read the message
"qrc:/VideoContext.qml:160: ReferenceError: video is not defined'

Congratulations, you just found a copy & paste error at line 160
How great is it debugging this way ?

Hey,
I'm testing the last appimage and I cannot play video. I get a white window.
Distro Xubuntu 17.10.

In the console I get this:

Hi,
I get this in the extracted files from QLC+_5.0.0_alpha2-TEST-20180319-x86_64.AppImage

Return value fixed on GIT. Weird that my GCC 5.4.0 didn't spot it. What GCC version do you have on 17.10 ?

I've also added the missing library to the linux bundle, but haven't created a new AppImage yet.

Hi Massimo,
I'm building and appimage right now I just see your commits on GIT. GCC version is: gcc version 5.4.1 20171010 (Ubuntu 5.5.0-1ubuntu2) . I'll inform later the results that of this build.

UPDATE:
Playing a video file, now QLC+5 inform duration, resolution, etc. Audio files are playing fine. Video play result in a white window with correct resolution, no sound and this error in console.

For a quick test, I added libQt5MultimediaQuick.so.5 in the platform/linux/linux.pro file. Now the videos are working fine. I'll do more tests in the next few days.

Damn, another library missing
Thanks for reporting. I'll add it later today

[mcallegari]

Should be fixed now on GIT.
They even changed the library name from Qt 5.9 to 5.10

[sbenejam]

I just see the commit on GIT. Thanks Massimo.

Hi Massimo,
FYI, I just tried the latest GIT changes. I tried it with a few video formats and all were played as expected.
