ffmpeg conversion from Flac to Ogg produces corrupted files
8 avril 2021, par experimentali transcoded flac files to ogg using this command


ffmpeg -i input.flac -c:a libvorbis -b:a 500k output.ogg


yes i use 500k to keep the highest quality possible, some of the files are ok, but some of them can not be played - Unsupported format or corrupted file says the foobar - also my icecast streamer cant read it. So there is something wrong with the files.


I believed it was due to the high bitrate so I tried


ffmpeg -i input.flac -c:a libvorbis -b:a 320k output.ogg


the same happened, some files were ok, some were not playable.
so I tried again with default using this command


ffmpeg -i input.flac -c:a libvorbis output.ogg


same thing. some files were ok, some were corrupted and not playable.


i have no clue why.


both flac and ogg are in the same family, what happened during the transcoding that it became a corrupted file ?


the spectral analysis does not show anything wrong - here it the ogg https://prnt.sc/115zdjl, here is the original flac https://prnt.sc/115zegw


i am really interested what is going on and how to make it work ?


can anyone explain ?


here is complete log

Dash.js not playing mpd files made with ffmpeg

UPDATE


Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a
dynamicmanifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.

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



Result from ffmpeg

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
