blog-demo's Issues

iOS 14.0 正在播放的视频在进入后台时会自动暂停

之前参考了你的文章做了后台播放，但是最近升级到了 iOS 14，发现进入后台时正在播放的视频会被暂停掉，请问你有遇到这个问题吗？

testVideoFilter中能添加GPUImageTwoInputFilter么？

testVideoFilter AVfoundation 播放加滤镜内存使用太高导出时也因内存过高闪退怎么解决?

memory issue

glow or soften filter

Hello, after reading your blog, I feel that you are very proficient in using gpuimage. I don't know if you know it.

Is there any way to perform these 2 effects with GPUImage?

A glow filter, that glows the white areas.
A soften filter, that creates a silk stocking, fog or dreamy effect.

testVideoFilter内存泄露

作者好，感谢提供的参考demo。
我这边运行demo发现，占用内存比较大1.2G，存在内存泄露。请问内存问题有更新吗？

testVideoFilter导出视频太大

[[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetHighestQuality];
这样写视频导出会大很多,有什么方法可以得到原视频的分辨率么

如何获取当前纹理渲染的图片啊？renderInContext拿不到opengl渲染的图片

如题

MFPixelBufferHelper 这个有没有其它方式替换

如何使用 metal 解析视频帧数据 CVPixelBufferRef ，也需要 convertYUVPixelBufferToTexture 吗 ? 系统库没相关提供方式吗？对音视频不了解，冒昧问一下

运行项目CVOpenGLESTextureCacheCreateTextureFromImage这个方法返回错误值-6683，不能运行！

作者能看下什么原因引起的吗？

如果想在实时视频并且输出录制文件中增加这些抖动的效果应该怎么做呢？

按照步骤来的，运行后
self.networkInstance = self.network->CreateInst(networkConfig, status) 这行出现以下报错：TNN/source/tnn/interpreter/tnn/model_interpreter.cc][Line 361] tnnmodel is invalid, maybe you should upgrade TNN

请问如何解决呢？
