在Android开发中,我们经常需要处理视频流数据,其中最常见的一种编码格式是H264。H264是一种高效的视频编码格式,广泛用于视频通信和流媒体传输。在本篇文章中,我们将介绍如何使用RK芯片解码H264视频流,并给出相应的代码示例。 什么是MPP MPP(Media Processing Platform)是一种多媒体处理平台,针对RK芯片开发的硬件解码...
-i input.yuv:指定输入文件路径和名称 -c:v h264_rkmpp:指定输出视频编码格式为h264_rkmpp(使用rkmpp硬件加速) output.mp4:指定输出文件路径和名称 请根据实际情况修改以上命令中的参数,希望对你有所帮助。
源图像是网络摄像头传入的1080P的H265数据，MPP解码后经过RGA裁剪，显示出来底部存在绿边。rga->ops->...
1:使用mpi_dec_test解码纯红色的h264文件生成的yuv色彩混乱,再使用mpi_enc_test把生成的yuv编码回去色彩恢复。 2:使用mpi_enc_test把yuv文件编码为h264后,画面色彩丢失,再使用mpi_dec_test解码为yuv色彩恢复。其中原始yuv文件色彩正常,使用ffmpeg编码h264色彩也正常。 哪位大佬能解答一下这个情况,万分感谢 Collabor...

on the Firefly gives WARNING: erroneous pipeline: could not link mpph264enc0 to flvmux0. Using x264enc works perfectly. Will this be fixed? Edit: This seems to be linked to the mppvideodec as well. Using another decoder and encoder, this works perfectly. When using the mppvideodec Gstr...
The current version of MPP fails when encoding H264 on a RK3288. The errors returned by MPP are as follows: hal_h264e_vepu2: hardware returns error:-1 mpp_enc: mpp 0x5598c69000 hal_hw_wait failed return -1009 The error was introduced pos...
