how to build a library without rootbuild?

I am using debian - armbian.

h264 bitrate exceed my value in runtime

hello
I am using this Configuration for my encoder.

VencH264Param h264ParamDefualt = {
.bEntropyCodingCABAC = 1,
.nBitrate = 1 * 1024 * 1024,
.nFramerate = fps,
.nCodingMode = VENC_FRAME_CODING,
.nMaxKeyInterval = fps,
.sProfileLevel.nProfile = VENC_H264ProfileMain,
.sProfileLevel.nLevel = VENC_H264Level31,
.sQPRange.nMinqp = 10,
.sQPRange.nMaxqp = 32,
};

but I wondering why bitrate exceed 1 * 1024 * 1024

调用接口报错Illegal instruction

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。

OMX is not sending frames

SoC: S3

I have verified that camera works good.

Trying to compile on the board (not buildroot)

Hi,

I want to compile the library on the board itself.
I cloned the repo, and start to compile with:

./bootstrap
./configure

but when running make I get the following error:

root@localhost:~/src/cedar/libcedarc# make
make  all-recursive
make[1]: Entering directory '/root/src/cedar/libcedarc'
Making all in base
make[2]: Entering directory '/root/src/cedar/libcedarc/base'
make[2]: Nothing to be done for 'all'.

make[1]: *** [Makefile:398: all-recursive] Error 1
make[1]: Leaving directory '/root/src/cedar/libcedarc'

What is the library that is missing? I couldn't find what library is associated to -lVE

thanks a lot!!!
