Title: Purple/Green screen with 4K raw video
Post by: Smarty77 on February 05, 2017, 10:46:15 AM
Hi I have a question.

I have a Himdeia Q5 pro running on firmware version: HMD-2.0.0 2016-11-18.175905.

I'm trying to play a 4K raw MKV video, but the picture is all purple and green and finally causes the mediaplayer to crash and hang.
This is the first 4K MKV with which I'm having this problem.
All other (4K) files play fine, except this one.

Below is the video media info:

Does anyone know what could be the cause of this?

V_MS/VFW/FOURCC / MJPG is an unusual codec which I guess isn't supported.

Any chance you could point me to a sample file?

I'm sorry but I don't have a sample file.
