aspect mode distortion with Raspberry Pi 4

[foocp]

Using a Raspberry Pi 4, with the latest 2019-07-10-raspbian-buster-lite, omxplayer distorts videos to always fill the entire space of the screen. Normal behavior would be to display black bars around the video if the aspect ratio doesn't match.

The same SD card when booted on a Raspberry Pi 3b+ doesn't do that.

Manually adding --aspect-mode letterbox doesn't help.

I've tried various screens, using both HDMI-to-HDMI cables as well as HDMI-to-DVI cables (when using a desktop screen that only has DVI input). This is the result of /opt/vc/bin/tvservice -s, which fits the hardware specs, so apparently it's correctly identifying the screen: state 0x6 [DVI CUSTOM RGB full unknown AR], 1920x1200 @ 60.00Hz, progressive

Running sudo apt show omxplayer tells me I'm running the current version: 20190723+gitf543a0d-1

Any ideas? Thanks!

I can confirm that. It also does not help if you specify the hdmi output with --display=2 or --display=7. also happens on both hdmi outputs.

Just tried and omxplayer is behaving as expected with black bars when video is either taller or wider than display's aspect ratio.

and contents of config.txt and mediainfo of a file with the issue.

removing

fixed the issue

@tofuSCHNITZEL and your "tvservice -s" output?

@tofuSCHNITZEL and your "tvservice -s" output?

state 0x6 [DVI CUSTOM RGB full unknown AR], 1680x1050 @ 60.00Hz, progressive

its the only non 16:9 display I have

Commenting out the line @tofuSCHNITZEL mentioned resolved my problem with distortion as well.

For me the problem is associated with having a Pi4 with official touchscreen and one HDMI monitor

The HDMI monitor is 1920*1080 16:9

I am playing suits-short.mkv, the video that was used to develop subtitles for omxplayer It is 1276*720 = 15.95:9

With the touchscreen disabled (ignore_lcd= 1 in config.txt) all is OK omxplayer --display 2 suits-short.mkv fills the screen omxplayer -- display 2 --aspect-mode letterbox suits-short.mkv fills the screen as it should do since aspect ratios are the same for video and display (well nearly!)

With the touchscreen enabled there are big black bars at top and bottom of screen omxplayer --display 2 suits-short.mkv - black bars omxplayer -- display 2 --aspect-mode letterbox suits-short.mkv - black bars, should definitely fill the screen in letterbox omxplayer -- display 2 --aspect-mode fill suits-short.mkv fills the screen as expected

Pi3 with a single HDMI display has always been full screen for omxplayer --display 2 suits-short.mkv

copied to #688 which better fits the symptoms
