[Bug]: OCIO failed to compile GL program with 1d luts with 2048 length in RV 2024.1.0
What happened?
RV is failing to compile the GL program when OCIO is using 1D luts with length 2048 both in forwards and inverse directions. The error is:
ERROR: Multiple declarations of 'ocio_lut1d_0Sampler' have different types (sampler1D and sampler2D)
I think the 2048 length must be on the limit where OCIO decides to use a 1D GL texture for one direction and 2D for the other, causing a name clash with different types.
List all the operating systems versions where this is happening
macOS 14.3
On what computer hardware is this happening?
Apple macbook pro M1 16GB

额我对比了一下，我用电视hdmi接口显示器播放60帧的弹幕和直接用电视上的这个软件播放，就是它显示的弹幕发现电视上的弹幕总是掉帧还是帧数不够，不知道为什么就显得有点卡，是那种微微卡不停帧数抖动，反正看的很难受，但是视频播放又非常流畅，我的电视处理器是最新的联发科q700（MT9653）芯片组，不太可能是处理器不足的问题，播放4k和hdr都没问题，都挺流畅的，反显得而那个弹幕就更卡了，希望大佬可以看看
我也对弹幕的帧数有疑问， 请问您在播放 50/60帧的视频 和 24/25/30帧的视频 时弹幕的帧数感觉是否有区别？ 您有没有用过 bilibilitv1.6.6-repair 和 BBLL 对比播放 不同帧率的视频 时弹幕有没有区别？

其实我还试过蛮多的，我给你总结一下 bv弹也是挺卡，bilibili1.6.6弹幕不那么卡 ，官方软件投屏弹幕基本不卡，然后是不同视频帧率，我只在bbll上对比过但是结果基本上从4k到1080 60再到720p弹幕感觉一样都是卡顿，并没有因为清晰度下降就变得流畅，我曾经直接就只看老版三国演义，就那个远古画质弹幕一样的卡顿，完全不如显示器接口的弹幕流畅
我这边也有此疑虑，以为是电视芯片处理不过来的原因，没想到大家都有注意到。
对呀，我刚开始用我的老电视播的时候，弹幕也很卡，我当时怀疑就是我处理器太老的问题，前两天。买了个新电视，看的时候发现还是卡，才发现这个问题

哦，对了，我还试过一个哔哩哔哩的车机版本是直接从小爱同学那里提取的，那个也不是很卡。

bilibili1.6.6弹幕不那么卡
我目测怎么感觉是bilibilitv1.6.6看起来没有BBLL舒服流畅？（25帧） 难到是字体的问题？
然后是不同视频帧率，我只在bbll上对比过但是结果基本上从4k到1080 60再到720p弹幕感觉一样都是卡顿，并没有因为清晰度下降就变得流畅，我曾经直接就只看老版三国演义，就那个远古画质弹幕一样的卡顿
我的意思并不是低画质或许会更流畅 而是我猜测弹幕fps会不会是和视频fps同步，那么50/60帧的视频上弹幕会不会看起来更舒服些 现在的4K应该只有30帧以内的 所以对比重点应该是在 1080P60/720P60 和 1080P/720P
，完全不如显示器接口的弹幕流畅
没明白，这是什么意思？
另外两个小问题，但感觉应该没什么影响 电视设置50帧60帧有没有区别 BBLL还有个Android-4.4的版本，我试过播放的区别好像不大
您试过的版本还真是全，甘拜下风

另外两个小问题，但感觉应该没什么影响 电视设置50帧60帧有没有区别 BBLL还有个Android-4.4的版本，我试过播放的区别好像不大
您试过的版本还真是全，甘拜下风
我明白你的意思了，就是说你怀疑是弹幕和视频帧率同步，但是据我观察不存在的，视频播放60帧时，弹幕尤其他会更卡，额，我跟你说一下我对比哪些视频，我对比的基本都是一些科技大佬的视频，比如影视飓风，极客湾，先看评测，他们的4k我都是下载确认过的4k60赫兹，当然然后还有1080p60我都试过，对于弹幕没啥影响（好像还更卡了），我这电视自带补帧功能，我补帧功能打开后，它的流畅度会有一丢丢改善，但是据我观察可能是啊，可能是从嗯50左右到55，有改善，但不多，跟显示器直接投屏比还是差的蛮远，所以真的希望优化弹幕流畅度啊😣
