我使用的是Linux 5.4主线,用的https://github.com/aodzip/cedar 搞出来了/dev/cedar_dev和/dev/ion,然后按照社区的文章采用gstreamer+omx的方式调用视频硬解码,报错Illegal instruction,不知道为什么,然后开始切换buildroot版本,19.08、20.02、22.02、23.02都尝试了,报错都是一样的,使用ffmpeg或gstreamer软解码都可以。然后就不用播放器了,按照Video_Decoder_API_Guide.pdf文档说说的接口直接调用AddVDPlugin或者CreateVideoDecoder也还是报错,这个错误有点奇怪。
