Issues with VLC for Android

Issues with VLC Desktop
Slow Video on J4105 with UHD600
The audio continues but the video is so slow to watch. The default “OpenGL video output” doesn’t work correctly sometimes.
- Set [Tools] ➞ [Preferences] ➞ [Video] tab.
- Select “X11 video output / XCB” as the display output.
Warning for other display output options:
- “XVideo output (XCB)” will pop-up another video window and crash GNOME sometimes.
- “GNU/Linux framebuffer video output”, “VDPAU output”, “Flashchen-Taschen video output”, and “Video memory output” will display blinking VLC logo and crash.
- “Dummy video output”, “Statistics video output”, and “YUV video output” will play audio wihout video.
Black Screen but the Sound Continuous. Restored in a few seconds
It seems related to data lost. VLC cannot get data in time. Increase cache helps to decrease the chance to happen.
- Set [Tools] ➞ [Preferences] ➞ [Show settings] to “All”.
- Select “Input / Codes” on the left tree.
- Scroll down and locate the “Advanced” group on the right.
- Increase “File caching (ms)” and “Network caching (ms)” to ‘6000’. If it still happens, increase until gone.
Hardware-Accelerated Decoding Works with Excpetions
Need an Intel GPU
To enable with Intel GPU, choose “VA-API video decoder” or “VA-API video decoder via DRM” in in [Tools] ➞ [Preferences] ➞ [Input / Codecs] ➞ [Hardware-accelerated decoding] and restart VLC. The default “Automatic” will disable it.
It works correctly on HD510. The CPU usage is about 15% to 20% different.
On BIOSTAR J4105NHU which comes with UHD600, the CPU usage is considerable lower (17 ~ 22%) if enabled. It is 56 ~ 83% if disabled.
There are tools monitoring GPU usage. intel_gpu_top shows the GPU video decode is working with VA-API. Please see Monitor Tools for detail.
There are still some issues with VA-API enabled.
On HD510, VLC might fails to quit. Need to kill (not end) the process manually. If there is audio withou video, reopen the file again without quiting VLC.
On UHD600, VLC fails to display videos and cannot quit running once paused. Need to kill (not end) the process manually. To pause, enable “Always” in “Continue playback?” and use stop instead.
