- The new PUT-WHATSAPP-MEDIA-FILE can encrypt and upload a blob of file data to
WhatsApp, and returns everything we'd need to make a protobuf message out of
that.
- However, important functionality is still absent: whatscl needs to gain some
support for sending protobuf messages for file uploads, and we'd also need to
integrate with some image/video libraries in order to do related processing
tasks.
- For example, uploading an image requires producing a JPEG thumbnail for it,
as well as figuring out its size.
- Uploading audio would require conversion to Opus.
- Maybe we could attempt to integrate with ffmpeg or something? This is likely
to get tricky.
