RK3588转码时需要添加水印，使用filter drawtext时报错 #35

使用命令： ./ffmpeg -i rtsp://admin:abc123abc123@192.168.100.80 -vf "drawtext=text='112233445566':fontfile=/usr/share/fonts/truetype/aenigma/lucid2.ttf:fontsize=64:x=500:y=500:fontcolor=red,scale_rga=w=1280:h=720" -c:v h264_rkmpp -q:v 80 -f matroska -f rtsp -rtsp_transport tcp rtsp://192.168.100.236/live/test1 报错信息： Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scale_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented Error while processing the decoded data for stream #0:0 Conversion failed! 请教下这个问题怎么解决？

To enable compilation of this filter, you need to configure FFmpeg with --enable-libfreetype and --enable-libharfbuzz. To enable default font fallback and the font option you need to configure FFmpeg with --enable-libfontconfig. To enable the text_shaping option, you need to configure FFmpeg with --enable-libfribidi. drawtext的说明好像是要enable-freetype，这个ffmpeg没打开这些选项，得重新编译下源码吧

编译ffmpeg的时候，--enable-freetype选项加了的，不加这个选项drawtext直接用不了 我已经找到解决办法了，rkmpp编码器其实是有加水印功能的(将MppEncOSDData数据设置到frame的meta就可以)，只是这份源码没有实现，需要自己添加； 直接使用编码器的OSD不太通用，如果只加水印编码器的够用了，如果硬解码后还需要再cpu上做其他操作然后再硬编那这个问题就绕不开了
