Video capture in Linux does not work (small file with empty green .webm video)

[Edmund Laugasson]

I know similar bug reports are made but problem still exist and is not solved like I noticed on some bug report comments.

Host: 64-bit Ubuntu 14.04.1 LTS with 3.18.5 generic kernel.

Using ATI-AMD graphics card HD 7770 series on host:

$ lspci -vnn | grep VGA 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X] [1002:683d] (prog-if 00 [VGA controller])

Also guest additions are installed in guests and 3D acceleration enabled from settings. Did not help. Still I get small .webm file with empty green video.

I tried also classic Gnome fallback - I mean I turned Unity off but still no help. I tried with or without guest additions - no help. Certainly also from settings I turned 3D acceleration on and off. I am running 64-bit Ubuntu 14.04.1 LTS and guest systems are Kubuntu 14.04.1 LTS, Lubuntu 14.04.1 LTS, Xubuntu 14.04.1 LTS Ubuntu Mate 14.04.1 LTS. I tried both 32-bit and 64-bit guests - same problem. I also tried different video players - VLC, SMPlayer, Totem, Xine - always blank green video and that's it

using 64-bit VirtualBox 4.3.20 r96996 in 64-bit Ubuntu 14.04.1 and 32-bit Lubuntu 14.04.1 guest - empty green video

I can verify that video capture does not work with an Ubuntu host. Video capture does work with an OSX host.

Linux box has Intel HD 4600 graphics.

Video capture works fine here on Ubuntu 14.04 and 14.10. The first thing to try is to disable 3D in the VM settings. Also a VBox.log file will show us the configuration of your VM and of your host.

Just a follow up. Same issue with VB 4.3.26 on Ubuntu-based hosts. Tried with multiple guests with 3D enabled and disabled but makes no difference.

Some further info:

1. Video Capture works in VirtualBox on OSX hosts
2. Video Capture works in VirtualBox on Windows hosts
3. Video Capture does not work in VirtualBox on Ubuntu hosts. webm is green.

Video capture on Linux hosts seems to be working in VB 5.0 Beta 1.

The issue seems to be caused by a libvpx incompatibility, at least on openSUSE 13.1.

I've just uploaded 4.3.28 packages for openSUSE 13.1. Could you download it and verify that it works now?

[robert spitzenpfeil]

I tested on 13.2, which comes with "libvpx1 1.3.0-2.1.2" - it doesn't work (only green).

It didn't work on 13.1 with libvpx from packman (1.3 or 1.4), but it worked after downgrading to 1.2 (standard package).

I can't test on 13.1 anymore, only 13.2.

[Frank Mehnert]

Thanks for testing. I've created openSUSE 13.2 packages which are linked against libvpx1 1.3.0. Would you mind testing again?

[robert spitzenpfeil]

It works.

[Frank Mehnert]

Thanks again for testing!
