uavs3e's Issues

Version.bat does not run on Windows 10

generally the sh command is not available in the Windows command prompt and neither are many of the commands used in the shell script.

The preconditions for building in a Windows environment should be described in the Readme

RealTime分支插值滤波armv8汇编实现10bit版本不兼容8bit

如题，com_if_filter_hor_8_arm64、com_if_filter_ver_8_arm64、com_if_filter_ver_8_ext_arm64等10bit汇编函数不接受BitDepth=8的参数，接口设计可兼容，且arm与x86在10bit版本编码8bit码流存在差异，建议进行兼容。

库与头文件安装目的错误

原因是使用了固定目录, 即/usr/include/与/usr/lib:
install(TARGETS uavs3e LIBRARY DESTINATION /usr/lib ARCHIVE DESTINATION /usr/lib)
install(FILES ../inc/uavs3e.h DESTINATION /usr/include/uavs3e/)
install(FILES ../inc/com_api.h DESTINATION /usr/include/uavs3e/)

而应为:
install(TARGETS uavs3e LIBRARY DESTINATION ${CMAKE_INSTALL_LIB_DIR} ARCHIVE DESTINATION ${CMAKE_INSTALL_LIB_DIR})
install(FILES ../inc/uavs3e.h DESTINATION ${INSTALL_INCLUDE_DIR}/uavs3e/)
install(FILES ../inc/com_api.h DESTINATION ${INSTALL_INCLUDE_DIR}/uavs3e/)

[编码时间显示错误]Linux fps计算错误显示编码时间比实际时间长较多倍

版本信息：Linux, Ubuntu 18.04.2 LTS, uavs3e version: 1.2.208_release

编码使用脚本：

import os
import time

uavs3_v1_2_208 = "/home/yxj/yangxijie/software/git/uavs3e/build/linux/uavs3enc"

yuv_video = "/mnt/video/E/FourPeople_1280x720_60.yuv"
yuv_width = '1280'
yuv_height = '720'
yuv_fps = '60'

set_qp = '45'
set_speed_level = '3'

coding_video = ' ./uavs3e.avs3'

begin_time = time.time()
cmd = uavs3_v1_2_208 + ' --speed_level ' + set_speed_level + ' --width ' + yuv_width + ' --height ' + yuv_height + ' --fps_num ' + yuv_fps + ' --fps_den 1 ' + ' --i_period ' + yuv_fps + ' --rc_type 0 ' + ' --input_bit_depth 8 ' + ' --qp ' + set_qp + ' --wpp_threads 40 ' + ' --frm_threads 40 ' + ' --input ' + yuv_video + ' --output ' + coding_video + ' --verbose 2 ' 
os.system(cmd)
end_time = time.time()
print('END' + str(end_time - begin_time) + 's')

可以看到输出log的后面Total encoding time为450s，但是用python脚本提供的时间计算发现实际编码时间为80.2s。这也导致fps计算错误。（也可能是我对log中Total的理解有差。

Could it support stdin?

Could it support reading from pipe (e.g. stdin) like SVT-AV1 does?

[编码性能疑问] uavs3-RealTime对比x265性能相差50%左右

如标题，在实测中，Random Access 单线程配置下，uAVS3e-RealTime与x265编码器性能相差很大。采用ClassA~ClassF，另外增加4个额外的4K视频序列，uavs3e-RealTime对比x265编码性能相差50%左右。这个与智媒之音（https://mp.weixin.qq.com/s/cXMHveOYegzuKi2rN7Ftgg）的评测结论相差很大。

uavs3e采用RealTime分支的最快档次，配置参数如下:
uAVS3 -f /bin/encoder_ra.cfg -p InputFile= Beauty_3840x2160_50_600.yuv -p OutputFile=Beauty_3840x2160_50_600_Anchor_qp32.bin -p SourceWidth= 3840 -p SourceHeight= 2160 -p FramesToBeEncoded= 600 -p FrameRate=30 -p SpeedLevel=6 -p IntraPeriod=100 -p RateControl=0 -p QP= 32

x265采用veryfast，具体配置参数如下：
x265 --input Beauty_3840x2160_50_600.yuv --preset veryfast -t psnr --psnr -o Beauty_3840x2160_50_600_Anchor_qp27.bin --input-res 3840x2160 --fps 30 --keyint 100 --qp 27 --no-wpp -F 1 --bframes 3

[实时分支问题]uAVS3_gop多次运行偶现码流不一致

问题现象：
使用RealTime分支编码器uAVS3_gop进行多次编码，会偶现每次跑码流不一致问题。
（同一命令，60次跑其中有1次与其他59次码流存在微小差异）

问题命令：
./uAVS3_gop -f ../bin/encoder_ra.cfg -p InputFile=./7680X4320_10bit.yuv -p threads-frm=9 -p threads-wpp=16 -p threads-gop=1 -p RateControl=3 -p TargetBitRate=35000 -p QP=32 -p SpeedLevel=7 -p FrameRate=100 -p FramesToBeEncoded=50 -p OutputFile=./out.avs3

环境：
CPU:ARM64
OS:openEuler release 22.03 LTS
GCC:10.3.1

RealTime分支内存泄漏问题

操作系统： linux
编译命令：

export C_FLAGS="-fsanitize=leak -fno-stack-protector -no-omit-frame-pointer -saditize=address -fsanitize-recover=address"
mkdir build && cd build
cmake .. -DCOMPILE_10BIT=1
make -j

编码命令：
./uAVS3_gop -f ../bin/encoder_ra.cfg -p InputFile=in.yuv -p OutputFile=out.avs3 -p threads-gop=2

编码过程中发现
存在以下内存泄露问题：

编码器avs3gop_t handle未释放
utest_gop.c中SPEED_TEST开启后，main、ReadOneth_10bit中存在内存申请后未释放
avs3_lib_create中对部分全局资源初始化，多次调用avs3_lib_create导致全局资源重复初始化，造成资源泄露

can it support on ARM？

至今无提供发行版文件下载

希望提供现成可用执行文件，促进自主标准推广试用评价等。不然像是闭门造车。

RealTime分支--地址消毒段错误问题

操作系统： linux
编译命令：

export C_FLAGS="-fsanitize=leak -fno-stack-protector -no-omit-frame-pointer -saditize=address -fsanitize-recover=address"
mkdir build && cd build
cmake .. -DCOMPILE_10BIT=1
make -j

基本编码命令：
./uAVS3_gop -f ../bin/encoder_ra.cfg -p InputFile=in.yuv -p OutputFile=out.avs3 -p SourceWidth=7680 -p SourceHeight=4320 -p SampleBitDepth=10 -p CodingBitDepth=10

问题描述：使用asan地址消毒器对RealTime分支进行测试，当存在以下输入场景时，产生段错误，asan地址消毒器接收到SEGV信号

输入CQP场景边界参数"-p RateControl=0 -p QP=0"，会引起对数组tab_QP_SCALE_CR的越界访问
输入未注册参数如"-p unknow=1"，会引起对tab_cfg_map的越界访问
输入不存在的配置文件，如"-f unknow.cfg"，会引起对空文件对象的访问
输入yuv像素值超过10bit最大值，会导致计算过程中出现段错误
输入"-p threads-gop=-1"，导致初始化过程中出现段错误

[编码选项编码log]--verbose选项提供更多的选择

uavs3e --verbose的说明为：

  -v, --verbose [INTEGER] (optional)
    : verbose level
	 0: no message
	 1: frame-level messages (default)
	 2: all messages

但是个人感觉1和2并没有差异……都包含逐帧的信息（Linux, Ubuntu 18.04.2 LTS, uavs3e version: 1.2.208_release，也可能是操作系统上版本的问题）

参考x265的--log-level说明

--log-level <integer|string>
Controls the level of information displayed on the console. Debug level enables per-frame QP, metric, and bitrate logging. Full level enables hash and weight logging. -1 disables all logging, except certain fatal errors, and can be specified by the string “none”.

0. error
1. warning
2. info (default)
3. debug
4. full

希望编码得到的基本信息为最开头的视频、参数设置信息和最后面的视频编码数据，省略中间逐帧的信息，而不是现在default的 frame-level messages

另外，如果可以，基本信息可以再精简一些，输出的log可以更贴近自然语言一些

是否支持8K视频

这个编码器以及对应的解码前，是否支持8k视频得编解码

[编码输出]自定义psnr.txt文件的位置

目前每次编码都会在当前路径下追加写psnr.txt，写入编码的psnr ssim和fps。

希望能在编码选项中添加类似--export --report --csv的选项，实现该文件位置的自定义

[编码输出信息] 编码log输出长串星号

版本信息：Linux, Ubuntu 18.04.2 LTS, uavs3e version: 1.2.208_release

编码使用脚本：

import os
import time

uavs3_v1_2_208 = "/home/yxj/yangxijie/software/git/uavs3e/build/linux/uavs3enc"

yuv_video = "/mnt/video/E/FourPeople_1280x720_60.yuv"
yuv_width = '1280'
yuv_height = '720'
yuv_fps = '60'

set_qp = '45'
set_speed_level = '3'

coding_video = ' ./uavs3e.avs3'

begin_time = time.time()
cmd = uavs3_v1_2_208 + ' --speed_level ' + set_speed_level + ' --width ' + yuv_width + ' --height ' + yuv_height + ' --fps_num ' + yuv_fps + ' --fps_den 1 ' + ' --i_period ' + yuv_fps + ' --rc_type 0 ' + ' --input_bit_depth 8 ' + ' --qp ' + set_qp + ' --wpp_threads 40 ' + ' --frm_threads 40 ' + ' --input ' + yuv_video + ' --output ' + coding_video + ' --verbose 0 ' 
os.system(cmd)
end_time = time.time()
print('END' + str(end_time - begin_time) + 's')

发现将log参数调整为0:None还是会在控制台输出长串的星号

使用python3 a.py得到输出：

编码出来的文件用HPM解码报错

通过uavs3e编码出来的文件

meiguo_LD.zip

编码命令： uavs3e.exe -i D:\Material\meiguo_1024_576_420_8.yuv -w 1024 -h 576 -d 8 -f 200 --fps_num 25 --fps_den 1 -q 60 -o meiguo_LD.bin -r meiguo_LD_rec.yuv

通过HPM对上述编码出的文件解码，程序崩溃
解码命令：decoder_app.exe -s -i D:\Code\AVS\uavs3e\bin\meiguo_LD.bin -o D:\Code\AVS\uavs3e\bin\meiguo_LD_dec.yuv

Build error

I'm getting the following build error:

[100%] Linking C executable uavs3enc
/usr/bin/ld: src/libuavs3e.so: undefined reference to `min'
/usr/bin/ld: src/libuavs3e.so: undefined reference to `max'

A git bisect shows that is caused by commit 218528c.

I can confirm that it was building fine until commit 457b5c9.

System information:

OS: Arch Linux x86_64
Compiler: gcc 10.2.0
CMake: 3.19.2
glibc: 2.32

这个编码速度是不是太慢了

不知道是不是我参数哪了没设对，这个编码器的编码速度每一帧都要花好几秒？我能想到的和编码速度有关的参数就这些了。
//#========== speed/quality trade-off ==============
cfg->speed_level = 4;

//#========== parallel configuration ===============
cfg->wpp_threads         =   4;
cfg->frm_threads         =   4;

[参数说明]Command Line Options 添加与优化

〇希望能够在编码器的参数中添加-h, --help的单参数：而不是每次都用./uavs3enc来调出

input[-i] is mandatory!
Configuration error, please refer to the usage.
< Usage >
  --config [STRING] (optional)
    : file name of configuration
  -i, --input [STRING]
……

从而调出usage界面

〇希望能够有专门的一个网页对Command Line Options进行解释（命令行--help只调出简版的），类似x265 cli

〇添加-V, --version的单参数

〇添加 --speed_level [INTEGER] (optional) : Level of coding speed的可选范围，1至3应该可以选，再往上选会发生什么呢……

uAVS3e-RealTime是否支持lowdelay P配置？

1、在bin目录下面之后encoder_ra.cfg的配置文件；
2、修改encoder_ra.cfg中NumberBFrames=0实现lowdelay P配置，但是只能编码8帧，运行卡住。

uAVS3_gop编码视频偶现程序无法正常退出

现象描述:
使用RealTime分支Demo进行8k片源编码时，所有帧编码结束后，程序无法正常退出。
该问题为偶现问题。
无法退出时堆栈如下：
avs3_threadpool_wait
avs3_lib_free
avs3gop_lib_free
main

命令：
./uAVS3_gop -f ../encoder_ra.cfg -p InputFile=7680x4320_10bit.yuv -p OutputFile=./xx.avs3

环境：
CPU:ARM64
OS:openEuler release 22.03 LTS
GCC:10.3.1

[仓库分支]添加仓库分支说明

目前版本库**有master, Realtime, aq, cudetheqt, sobel_ql五个分支

在任何README.md中都没有关于这几个分支差异的说明，希望能在主分支的README中添加关于分支的说明

如果分支与master分支相差较大，希望能在该分支下添加README说明（如Realtime分支

如果分支无用，希望可以删减以精简项目

BUG report in scenecut-detection fuctions

if (h->cfg.scenecut) {

while (cur_ip_idx) {
double sc_ratio = loka_get_sc_ratio(&h->pinter, h->img_rlist[cur_ip_idx].img, h->img_lastIP, bit_depth);
if (sc_ratio <= sc_threshold) {
for (int i = 0; i <= cur_ip_idx; i++) {
h->img_rlist[i].sc_ratio = 0;

}
cur_ip_idx--;
}
if (cur_ip_idx == 0) {
add_input_node(h, h->img_rlist[cur_ip_idx].img, 1, FRM_DEPTH_0, SLICE_I);
//
update_last_ip(h, h->img_rlist[cur_ip_idx].img, SLICE_I);
//
shift_reorder_list(h, cur_ip_idx);
return;
}
}
}

update_last_ip(h, h->img_rlist[cur_ip_idx].img, SLICE_I); should be added there after an I frame asserted in the node, or it might cause h->img_lastIP not updated and results in a series of errors.
