I am using the trial version of Video Kiosk and the movies originally played correctly but now they are displayed as green. The aspect ratios match the videos so it’s as if all the output has become green.
Is this because the trial version does this after a certain period of time? If not what else could it be? I am playing H.264 mp4 videos.

The free trial is 100% functional other than the water mark. It does not alter the movie content. It sounds like either a problem with the device or with the movie. I suggest you reboot the device and if that does not solve it delete the movie and copy it back onto the device again. If that still does not solve the problem please contact us by email so that we can investigate the problem further.

replied 7 years ago I did reboot the unit and this did not fix it. Before replacing the videos I used ES file explorer to see the videos on internal storage and they all played correctly. If Video player, ES Media player and the Video app all play the files correctly why doesn’t your software?
I am using a DropSync and Dropbox but can’t see this being the issue unless you cache the video files in yet another location. An image file does work correctly.
I then deleted a video file and waited for Dropsync to re-download it. I then restarted your software and it still displayed as green.
Is there anything further I can try? I could send a dropbox link to the videos I am trying to play.

replied 7 years ago I worked out the issue. Turning off ‘Use textured video views’ fixed the issue. Is this just a perofrmance issue e.g. can be fixed by dropping MP4 bit rate or getting better Android hardware?

The difference is that Textured VideoViews use the 2D rather than the 3D hardware accelerated rendering pipeline. This is why Textured VideoViews can be faded and blended with other views and also why they don’t suffer from the black flash problem on Amlogic based Android devices. From what you describe, it appears this particular .mp4 requires the 3D hardware accelerated pipeline on your specific device. It could be you can use the Textured VideoViews with a different device, it could be that a mp4 with less compression will work on your device. Please share the video with me I will try it on several devices here and then I can provide a more detailed answer.

adminI have the file. I’ll try it on a couple of devices and get back to you with the results.
I tried the video on 5 different devices using Textured Video Views. It played on 4 of the 5 and I got a black screen on 1 of them. I think it has to do with the advanced MP4 encoder used to create the original file combined with a poor choice on the device (by the manufacturer) for decoding so I re-encoded the file using Ffmpeg’s default settings and the re-encoded file played fine on all 5 of the devices. Can you try the re-encoded file on your device using Textured Video Views? You will find the new video here: https://www.dropbox.com/s/ui9ri7mnivuj6iy/AndrewTranscode.mp4?dl=0
