A mailing list is not much different than emailing someone, but the main difference is that your message is received by everyone who subscribes to the list. It is somewhat like a forum but in email form.
See the ffmpeg-user archives for examples.

We cannot provide help for scripts and/or third-party tools.
First you must subscribe. Then all you have to do is send an email:
Email ffmpeg-user-request@ffmpeg.org with the subject subscribe.
Or visit the ffmpeg-user mailing list info page and refer to the Subscribing to ffmpeg-user section.
The process is the same for the other mailing lists.
Email ffmpeg-user-request@ffmpeg.org with subject unsubscribe.
Or visit the ffmpeg-user mailing list info page, scroll to bottom of page, enter your email address in the box, and click the Unsubscribe or edit options button.
The process is the same for the other mailing lists.
Please avoid asking a mailing list admin to unsubscribe you unless you are absolutely unable to do so by yourself. See Who do I contact if I have a problem with the mailing list?
Note that it is possible to temporarily halt message delivery (vacation mode). See How do I disable mail delivery without unsubscribing?
Some messages are automatically held in the moderation queue and must be manually approved by a mailing list admin:
These are:
The queue is not checked on a regular basis. You can ask on the #ffmpeg-devel IRC channel on Libera Chat for someone to approve your message.
You should have received an email with the subject Your message to <mailing list name> awaits moderator approval. A link is in the message that will allow you to delete your message unless a mailing list admin already approved or rejected it.
See the Archives section on the FFmpeg Contact page for links to all FFmpeg mailing list archives.
Note that the archives are split by month. Discussions that span several months will be split into separate months in the archives.
Click the email link at the top of the message just under the subject title. The link will provide the proper headers to keep the message within the thread.
Note that you must be subscribed to send a message to the ffmpeg-user or libav-user mailing lists.
Perform a site search using your favorite search engine. Example:
site:lists.ffmpeg.org/pipermail/ffmpeg-user/ "search term"
You can ask for help in the official #ffmpeg IRC channel on Libera Chat.
Some users prefer the third-party Nabble interface which presents the mailing lists in a typical forum layout.
There are also numerous third-party help sites such as Super User and r/ffmpeg on reddit.
See https://en.wikipedia.org/wiki/Posting_style#Top-posting.
Instead, use trimmed interleaved/inline replies (example).
The message size limit is 1000 kilobytes. Please provide links to larger files instead of attaching them.
Anywhere that is not too annoying for us to use.
Google Drive and Dropbox are acceptable if you need a file host, and 0x0.st is good for files under 256 MiB.
Small, short samples are preferred if possible.
Highly unlikely.
However, you may see a spam in the mailing lists on rare occasions:
Use the List-Id. For example, the ffmpeg-user mailing list is ffmpeg-user.ffmpeg.org. You can view the List-Id in the raw message or headers.
You can then filter the mailing list messages to their own folder.
Sometimes you may want to temporarily stop receiving all mailing list messages. This "vacation mode" is simple to do:
Alternatively, from your subscribed address, send a message to ffmpeg-user-request@ffmpeg.org with the subject set delivery off. To re-enable mail delivery send a message to ffmpeg-user-request@ffmpeg.org with the subject set delivery on.
This is due to subscribers that use an email service with a DMARC reject policy which adds difficulties to mailing list operators.
The mailing list must re-write (munge) the From: header for such users; otherwise their email service will reject and bounce the message resulting in automatic unsubscribing from the mailing list.
When sending a message these users will see via <mailing list name> added to their name and the From: address munged to the address of the particular mailing list.
If you want to avoid this then please use a different email service.
Note that ffmpeg-devel does not apply any munging as it causes issues with patch authorship. As a result users with an email service with a DMARC reject policy may be automatically unsubscribed due to rejected and bounced messages.
There may seem to be many things to remember, but we want to help and following these guidelines will allow you to get answers more quickly and help avoid getting ignored.

Some email providers have blacklists or spam filters that block or mark the mailing list messages as false positives. Unfortunately, the user is often not aware of this and is often out of their control.
When possible we attempt to notify the provider to be removed from the blacklists or filters.
Excluding messages that are held in the moderation queue there are a few other reasons why your messages may fail to appear:
Users with an email service that has a DMARC reject or quarantine policy may be automatically unsubscribed from the ffmpeg-devel mailing list due to the mailing list messages being continuously rejected and bounced back.
Consider using a different email service.
