Black Line Issue

@VineshChauhan24
I guess it may be your Video source has something rong. For example, It does not comply with the specifications of Alpha video. Alpha video requires a half width on the left side,Same for the right half. Can you upload your video file? Then provide a link to the video file, such as uploading to your github repository.

@VineshChauhan24
Can you provide these two video files? One is 1080x1920, the other is 1080x2340. You can upload these two video files into your github repository, then i can download them.

Now, I’m not sure wether it’s the problem of the program or the video resource.

If you can provide video resources, and it turns out to be a program problem, I think I can fix the bug this weekend.

Actually the resolution is of Android Devices not for Video. video's resolution is 1080x960

Video Resolution = 1080x960
Android Device 1 = 1080x1920 (working good)
Android Device 2 = 1080 x 2340 (black line issue)

Hello two friends, I have proved that it is the problem with the video file. You can look at the code in Module app2 and libgiftplayer2. Please pull the latest code first.

//when set 0.5f, then got Black vertical line
giftPlayerView.init(this, "test2.mp4");
//when set 0.4956f, then it is ok. So the alpha video file is bad.
giftPlayerView.init(this, "test2.mp4", 0.4956f);

This proves that the left and right are not absolutely equal width. The left width is 0.4956, and right width is 1-0.4956.

Hello meikaiss sir,
Thank you for replay,,,

i tried with new code and set 0.4956 but this video work perfect,,, but when i try different video not working show black line,

Alpha Video Perfect working width and height its perfect, because i tested to ffmpeg with overlay command , i am 100% sure no any problem in alpha video, you also check with ffmpeg command i put ffmpeg command and video file in drive please check ,,

@chirag9333
0.4956 is only for the specific video file. When you change to anthor video file, I mean you should change to another intermediate position parameter. This is just my conclusion based on the performance of opengs，I am not sure whether It has something wrong about my conclusion.

I have checked your ffmpeg command and video file in drive. It seems that the alpha video is really ok with ffmpeg. I also don't know why. There maybe something wrong in MediaPlayer and OpenGLES.

I provide an idea, You can try to use FFMPEG and OpenGLES to play video, use OpenGLES to solve the synthesis of transparent channel.

I am not sure whether I have enough time for your business work. I'll try my best to help you with small problems.
