# 通用参数字符串
# 统一的输入参数，本文以常见的mkv（H264+AAC）格式为测试素材
# (其中部分需要用到的mpegts文件，采用它派生的tt.ts)
# 测试前的准备工作
# 1）PC 上有 D、E 分区
# 2）E分区上准备下面 mkv/mp4/ts 源文件: 推荐格式为 H264+AAC
# 3）准备拼接需要的hls分片至少 5片，名称及目录：
# E:\material\ffmpeg_hys_python\hls_part\h264_part0.ts
# E:\material\ffmpeg_hys_python\hls_part\h264_part1.ts
# E:\material\ffmpeg_hys_python\hls_part\h264_part2.ts
# E:\material\ffmpeg_hys_python\hls_part\h264_part3.ts
# E:\material\ffmpeg_hys_python\hls_part\h264_part4.ts
# e:/material/ffmpeg_hys_python/hls_part/hls_concat.txt
# hls_concat.txt文件每行内容格式描述一个分片绝对路径，如下所示共5片：
# file 'file:E:/material/ffmpeg_hys_python/hls_part/h264_part0.ts'
# file 'file:E:/material/ffmpeg_hys_python/hls_part/h264_part1.ts'
# file 'file:E:/material/ffmpeg_hys_python/hls_part/h264_part2.ts'
# file 'file:E:/material/ffmpeg_hys_python/hls_part/h264_part3.ts'
# file 'file:E:/material/ffmpeg_hys_python/hls_part/h264_part4.ts'
# 4）准备图片转视频所需的序列化png图片(1000左右)，背景MP3音频
# 5) d分区，创建输出目录 d:/otest/ d:/otest/png d:/otest/jpg

#
# 2 转码
# 1）转成 H264+AAC (指定视频分辨率, B帧，关键帧间隔，不指定视频码率默认是 VBR 模式)
# ffmpeg -y -i e:/material/tt.mkv -vcodec libx264 -s 640x360 -bf 2 -g 25 -acodec aac -f mp4 d:/tt_h264_aac.mp4
#
# 2）转成 HEVC+AAC（增加指定音频采样率，码率，声道，可选）
# ffmpeg -y -i e:/material/tt.mkv -vcodec libx265 -preset medium -s 640x360 -bf 2 -g 25 -acodec aac -ar 48000 -ab 128k -ac 2 -f mp4 d:/tt_hevc_aac.mp4
#
# 3）带NVIDIA显卡（支持H264/HEVC硬件加速）
# ffmpeg -y -c:v h264_cuvid -gpu 0 -i e:/material/tt.mkv -c:v:0 h264_nvenc -gpu any -s 640x360 -g 25 -acodec copy -f mp4 d:/nv_h264_aac.mp4

#
# 4) 输出 MPEGTS CBR（指定视频码率 1Mbps，音频64Kbps，整体码率输出1.25Mbps，恒定码率模式，通常需转码带上恒定码率控制参数）
