Avidemux Forum

Thank you for all of your help.  I've now downloaded Python and going to do one of the online courses.  It's remembering all the syntax. 
Bye for now

You can safely take r240908, the packaging error is resolved. As a bonus, your Avidemux won't mess up mono or multi-channel (i.e. non-stereo) LPCM tracks in loaded MOV files, among some other fixes

Packaging fixed in r240908. Additionally, a few unneeded DLLs identified and excluded from packaging, thus smaller package size.

Setting the topic non-sticky.

In case it helps - most of the I-frames are I-FRM, but where the issue occurs they switch to I-TFF for 4 frames, and then playback resumes with the next I-FRM. Thanks

I appear to have got it working.
I downloaded 2.8.2 rel 240804 and it all seems to be okay.  I need to test the files with the samsung tv but it looks promising.  Appreciate it's not the latest version but for now it's fine.  Will experiment a bit more later.

Hi
I didn't compile the version I used, i downloaded the executable.  It's V2.8.1

I've tried this again and certainly the error has disappeared.  However, the file source dialogue opens, it permits me to select a directory but the dialogue for the output directory never appears.  It whirrs for a few seconds then shuts the GUI down.  I've attached the py file as a txt file but not sure I have made any mistakes from what i can see.  Would you mind please having a look as i may be being stupid.

Many thanks for your help

Using the August 2.8.2 nightly build (and 2.8.1) on a Mac.

The linked DVB-T2 transport stream has an issue at 5 seconds - if the ts file is played in VLC a short moment of pixelation is seen. When played back in avidemux this is handled seamlessly without the defect. However on export from avidemux without re-encoding - e.g. as .mp4 copying the audio and video, there is frozen frame that lasts several key frames.

Is there anything more that can be done to make the exported file more like the way playback is handled in avidemux? Thanks!

Hello,
I am using the KDE Version of Fedora 40. KDE Plasma 6.1.4, KDE Frameworks 6.5.0, QT Version 6.7.2. My Hardware is an Intel i5-13500 with integrated Intel Xe Graphics.
I use Avidemux from the RPMFusion Repository 2.8.1.-4.fc40. This may be an old version. I have seen that in Fedora 41 RPMFusion there is a newer version 2.8.2git20240430. Maybe I should wait for this version.

I did some tests now.
When I start avidemux then the behaviour depends on the used Display configuration.
- Video Display: QT or OpenGL, Enable OpenGL support on: Black Window with Cursor displayed several times, then no Display, No error messages in Terminal
- Video Display: QT or OpenGL, Enable OpenGL support off: No picture displayed
- Video Display: LibVA, Enable OpenGL support off: I get:
[displayXError] 07:04:20-467  LibVA Error : <vaPutSurface ( ADM_coreLibVA::display, img->surface, (Drawable)widget, 0, 0, sourceWidth, sourceHeight, 0, 0, displayWidth, displayHeight, NULL,0 ,0):invalid parameter:18>
18 =<invalid parameter>
 [putX11Surface] 07:04:20-467  putX11Surface failed
- Video Display: LibVA, Enable OpenGL support on: The Window showing Artefacts from Cursor and other window parts and same error message.

When I start avidemux with the --platform xcb option I get the same errors when using libVA. Only the configuration with Video Display Qt or OpenGL are ok.

The case Video Display: QT, Enable OpenGL support on:  looks similar to the transparency issue I described above.

These are different issues than the mentioned NVIDIA problem.

@joma, please provide more info (Fedora version, graphics card, drivers, the origin of Avidemux build and build options used). The change you suggest doesn't help on Fedora 40 with NVIDIA graphics card using the closed-source driver, the error is

qt.qpa.wayland: Could not create EGL surface (EGL error 0x3003)

qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface: 0x0
and the program terminates. Adding --platform xcb to command line is still required.

In any case, OpenGL display remains broken starting with Qt 6.4.0 (setUniformValue() fails).
