在 RK3568 平台,使用编译出来最新的 mpp 库,解码对方发送的 hevc 码流时,一直报错如下:

mpp[873]: H265D_PARSER: PPS id out of range: 0
mpp[873]: H265D_PARSER: hls_slice_header error ret = -1004
mpp[873]: H265D_PARSER: Error parsing NAL unit #0,error ret = 0xd.
mpp[873]: H265D_PARSER: current stream is no right skip it (nil)

导致无法显示任何图像,请问可能是什么原因呢?

估计是开始的 vps / sps / pps 数据给丢了

但是用 ffplay 使用软解码是可以解出来并显示的，😂

请问这种情况还可以有办法使用 mpp 硬解码解出来么？

看看 init 的时候有没有 extra_data 没送进来

iysheng commented 1 year ago

这是我的 mpp 初始化函数
请问你说的 init 的时候，是说的我这边配置解码器的时候么？
请问你说的 extra_data 是指的是什么呢？

ffmpeg 解封装的时候，会把封装里的 sps/pps 这些数据用一包 extra_data 送下来，如果少了这些数据，后面的码流数据就无法解码了

HermanChen / mpp

解码 hevc 码流一直报错 PPS id out of range: 0 #56

if 0
