更换软件版本:如果当前使用的软件版本不支持NV12格式,考虑升级到支持该格式的最新版本。 调整软件设置:某些软件可能允许用户选择像素格式。检查软件设置,看是否有选项可以切换到NV12格式。 5. 提供解决步骤 假设用户是在使用某个视频处理软件时遇到此问题,以下是一个可能的解决步骤示例: markdown ### 解决步骤 1. *...
在HarmonyOS鸿蒙Next的Surface模式下,配置视频硬解码器中的OH_MD_KEY_PIXEL_FORMAT参数是一个关键步骤,它直接决定了解码后视频数据的像素格式。 OH_MD_KEY_PIXEL_FORMAT参数应当设置为解码器所支持的像素格式之一,这些格式通常在解码器的文档中有所说明。在Surface模式下,常用的像素格式可能包括YUV420、NV12等,这些格...
I am trying to transcode a H264 video from default/YUV420P format to NV12 pixel format. I tried running the sample multi transcode as below. Transcoding says success but when i ffprobe output1.h264, I see YUV420P as pixel format. Request the team for guida...
The present invention discloses a GPU will be converted to ARGB pixel format by the method and system NV12, involving pixel format conversion. 该方法的步骤为:在图形编程接口的二维纹理接口中创建1个8位像素格式的Y平面储存纹理和1个16位像素格式的UV平面储存纹理;将需要转换的ARGB储存纹理输入至GPU,GPU...
