Welcome to the ZDoom Forums!

This was a recent topic about encoding IVF cutscenes with FFMPEG: viewtopic.php?p=1228695&hilit=video#p1228695 It is the only video format in the list of supported formats that supports more than 8 bits of color.

For extracting the audio as a separate file FFMPEG can also be used: ffmpeg -i <input> -vn -codec:a libvorbis -b:a 128k <output.ogg> That would output 128kbit/s OGG Vorbis audio. Use "libopus" instead of "libvorbis" for Opus audio, or "pcm_s16le" for regular uncompressed PCM audio.

This isn't useful anymore, but out of curiosity I checked the differences for myself. I tested on modern hardware so the absolute OpenGL ES results mean nothing, but the relative results are still quite something; it is now unplayable. Vulkan is slightly slower, and OpenGL got a nice boost indeed ...

Ever wanted to make manipulating groups of sectors easier? Or split a map up into zones to show enter\leave messages? Without having to resort to using lots of special linedefs and sector tags? I have, so I wrote a quick bit of ZScript and ACS to accomplish just that. The demo MAP01 in the attached ...

Great work! The sprite shadows are my personal favourite new feature this release. And while its not listed in the changelog, LOOP_ comments for Opus audio are now also supported to bring it up to par with other audio formats.

I've done this exact thing in Verdant Citadel, and it also was rather painful. The solution I ended up with was having a 3D floor be the floor of the elevator, which is tagged (present) in every floor of the shaft. Then you can move the dummy sector's ceiling and floor around with ACS to wherever ...

I've posted a pull request that adds support for this feature: https://github.com/coelckers/ZMusic/pull/18

In the 4.5.0 release Opus is finally supported. The LOOP_START, LOOP_END and LOOP_BIDI tags however are not parsed like they are for FLAC and Vorbis audio. Here is a pk3 that replaces the MAP01 and MAP02 music . The MAP01 track is a Vorbis file that has an intentionally awful loop start and end ...

Awesome, a lot of new stuff. Great work as usual!

I've actually thought a lot about a feature like this, but have not yet made an attempt at adding it. It would have to be possible to specify multiple loop start and end points per music track, because there might be a brief delay when starting a completely new music track. For OGG and FLAC that ...

Sometimes (but the exact circumstances elude me) the game will simply crash. The earliest I've been able to reproduce this is at the end of the hallway with the key sockets, when you shoot the shotgunners that come out of hiding from the right. Though sometimes it happens without shooting anything ...

I figured this thread had run it's course so didn't update it with test 4. There will be a test 5 at some nearby point.

Thanks for the test and extensive feedback Enjay! Other people have also reported not being able to find all secrets so I did a search in GZDoom Builder, turns out a fair number of them were things marked as secret that were just decoration! And even the player 1 start was marked as secret... After ...

The climbable waterfall is probably a bug, isn't it? Yes, though I can't seem to find a way to prevent it. It isn't terribly important anyway, getting back up it doesn't lead anywhere special after all. Excellent map so far. I created an account to show you a moving ground texture: Thanks, fixed ...

Thank you for the super detailed and thorough test! Glad you caught the shader bug too, fragment shaders are not my specialty. The silent barrels were something I missing entirely, I'm not sure how I never noticed that... The last platform part is intended to be some sort of a boss battle. Was it ...
