The video is not encrypted with DRM. When I tried to download with FFmpeg, success, but FFmpeg automatically select the worst quality (144p).



FFmpeg command I use :



ffmpeg -i https://anevia115(dot)mncnow(dot)id/vod/eds/kiko-season1-eps1-mobil-kabur-anv6/_/sa_dash_vmx/kiko-season1-eps1-mobil-kabur-anv6.mpd -c copy kiko1.mp4

Tried youtube-dl & streamlink but failed.
So, I use FFmpeg because it success to download the video and audio. I have read FFmpeg documentation but I have no idea what command should I use.
What command should I use to select another quality ? (ex : audio 64 kbps, video : 720p)





Note : just change (dot) to

please check encoding it is fastest or not
11 mars 2020, par Don Rigsi have a 2 line to convert from mp4 to avi
`avs2avi a.avs target.avi -c xvidffmpeg -i source.wav -i target.avi -c:a mp3 -c:v copy targetfinal.avi`
here it is the a.avs :
`LoadPlugin("C :\MEGUI\tools\ffms\ffms2.dll")
FFVideoSource("source.mp4", threads=1)
LoadPlugin("C :\AVISYNTH\plugins\zoom.dll")
Levels(0, 1.0, 250, 10, 255)
trim(20,960)
crop(4,4,-4,-4)
BilinearResize(1920,1080)AssumeScaledFPS(80,63).ChangeFPS(last)`
it seem not fast enough, can you have any advice to make it more faster ?
