Thank you. I'm trying to convert an mp3 file to ogg file to send through to a WhatApp contact through their API. The Whatsapp API only accepts " audio ogg-file in opus codec". I convert it using
ffmpeg -i audio.mp3 -c:a libopus newfilename.ogg newfilename.ogg does not play in whatsapp when I send it. I downloaded a whatsapp voice note that does work in whatsapp and looked at the properties of the file (Below) ===================== General ===================== Complete name : C:\Users\user\Desktop\opusvoice.ogg Format : Ogg File size : 36.1 KB Duration (ms) : 15s 507ms Overall bit rate : 19.1 Kbps ===================== Audio ===================== Id : 100 (0x64) Format : Opus Duration (ms) : 15s 507ms Channel(s) : 1 channel Channel positions : Front: C Sampling rate : 16.0 KHz Compression mode : Lossy Writing library : WhatsApp ================================================ I'm trying to match it so that it works.

I'm new and still learning. :-) That’s good, but in that spirit, you should look up what top-posting is and avoid doing it in this mailing list. > I need to convert with the following settings: > > Bitrate of 19.1kbps > 1 channel > Sample rate of 16.0khz That would look like this: ffmpeg -i audio.mp3 -c:a libopus -b 19.1k -ac 1 -r 16k newfilename.ogg But I hesitate to just give you a command you might not understand because a lot of your questions don’t quite make sense… Such as > Is the Writing library " Lavf58.28.102" the same as "WhatsApp"? What is it that you’re trying to do? It’ll be easier to help if you give us a bigger picture. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
