No video [RESOLVED]
« on: September 07, 2017, 11:17:26 PM »
Using Antergos and the latest ver of Avidemu, 2.7.0. I'm a Linux n00b so if you want me to gather logs or try something, be REALLY detailed with your response please. :)

I installed Avidemux(Qt) and when I load a MKV file, I get audio but no video. My gfx card is a Nvidia GTX 670, using proprietary drivers. Any ideas?

Thanks

Most likely you need to install either one of these if available in Antergos:
- VDPAU or/and OpenGL
Code: [Select]
dpkg -l vdpau*
Code: [Select]
ii  vdpau-driver-all:amd64         1.1.1-3ubuntu1       amd64                Video Decode and Presentation API for Unix (driver metapackage)
ii  vdpau-va-driver:amd64          0.7.4-5              amd64                VDPAU-based backend for VA API
ii  vdpauinfo                      1.0-1                amd64                Video Decode and Presentation API for Unix (vdpauinfo utility)

Code: [Select]
vdpauinfo would tell if the card does support HEVC, in case the used code is HEVC, in this example the last 4 are not supported

some hints can be found here: Library Info & Tools from Ubuntu, don't know how this would translate to Antergos.

Please launch Avidemux in terminal

Code: [Select]
avidemux3_qt5 | tee ~/admlog.txt
try to load a video, quit Avidemux, compress admlog.txt and attach it to your reply.

Otherwise try disabling hw accelerated decoding in Avidemux and setting video output to something failsafe like "Qt" (the worst option, but should work if everything else fails).

Here you go: (thanks)

EDIT: Never mind, it's working now. I went into preferences and checked the 'Decode video using VDPAU (NVIDIA)' and everything is AOK. Sorry about that. :)

When I went into the Antergos software manager and searched for VDPAU and OpenGL, I saw lots of hits for those two and to my untrained eyes, I -think?- the proper ones are installed. (That had green boxes beside them.)

And those commands didn't work in Antergos. :(

I've noticed Antergos is an Arch Linux based distro. Not like Ubuntu that is Debian based.

glad you figured this one out:
EDIT: Never mind, it's working now. I went into preferences and checked the 'Decode video using VDPAU (NVIDIA)' and everything is AOK.
