Issues for TV Arib Subtitle

Open YouTouYip opened this issue 1 year ago • 4 comments

Just downloaded the player and everything is good - Except the support for DVB Subtitles

I tried to watch TVB J2 ( a Hong Kong TV Channel), and the signal is from my Tvheadend server, but the subtitle itself looks like this cfdcf417183f7a01201f74e334f9ef54

You can see the subtitle looks very strange - in a wrong aspect, if I moves to VLC, it will look like this 7bc7de8638293710951001f67542eb5c Which is in a correct aspect, and looks same as TV set As Broadcast TV in Hong Kong uses external subtitle very widely and almost all channels in HK use external subtitle instead of the internal one, it's a issue for watching live TV in Hong Kong

Also, If I watch Japanese TV, the subtitle will not be shown correctly, this issue is might caused by lack of ARIB Subtitle support {C4E0BE28-6DA0-4eb9-974C-F5E617D4671D} {9B37562D-D77E-4861-A16E-10C91599D974} This is a screenshot by using TVTest, a player designed for Japanese Broadcast TV, which can see the subtitle looks correctly as it looks in TV

And VLC is showing the subtitle correctly as well {E65EA36F-165C-49e6-9A17-EFF2526D83D2}

Problem is with Arib support in FFmpeg. Even if I enable it, it's bugged and requires FFmpeg code change to make it work correctly. I have to implement Arib directly in QMPlay2.
