Distortion when playing videos with different pixel format

[bongas]

When I play two videos after each other, the second video is heavily distorted if the videos have different pixel formats.

I start first video by calling avPlayer->play(video1); and on stopped() signal I do same call avPlayer->play(video2). I have tested with several videos but for example I use:
Video1: MOV (mpjeg, yuvj422p)
Video2: MP4 (h.264, yuv420p)

If I swap the videos and play video2 first then video1 is distorted. Quite frequently the app is also crashing on row 585 in VideoShader.cpp. I'm using the latest code.
I do get a warning when switching to the second video "Can not copy codec properties when it's open" so it looks that the decoder/codec is not completely closed before playing the next video...?

Environment:
Ubuntu 14.04
Latest QtAV code
ffmpeg decoder

Thanks for your great work!

Here are two sample videos: http://ge.tt/6j3BzEO2/v/0
I can also upload the simple test app if you need...
Thanks!

Here's a screenshot of the distortion:

what's your ubuntu version or libavutil version? If libav<10 or ffmpeg<2.0, QtAV may crash at glTexSubImage2D because the data to be uploaded may be released by ffmpeg/libav. I can not control the data lifetime without copying the data (copy can be expensive). Later versions support reference counted frames, thus I can ensure the data is always available
I'm downloading the video

can you upload to another place, for example google drive. The download speed is very slow here

I'm using FFmpeg 2.4.4 on Ubuntu 14.04

I will try another solution for old libav/ffmpeg.

Oh, I can reproduce it on my computer now

That's great... (for me)
Then I cross my fingers hoping that you can find a solution too... :)
Thanks!
