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.
All you have to do is send an email:
If you are not subscribed to the mailing list then your question must be manually approved. Approval may take several days, but the wait is usually less. If you want the message to be sent with no delay then you must subscribe first. See How do I subscribe?
Please do not send a message, subscribe, and re-send the message: this results in duplicates, causes more work for the admins, and may lower your chance at getting an answer. However, you may do so if you first delete your original message from the moderation queue.
Subscribing allows two things:
No. You can still send a message to the mailing list without subscribing. See How do I ask a question or send a message to a mailing list?
However, your message will need to be manually approved by a mailing list admin, and you will not receive any mailing list messages or replies.
You can ask to be CCd in your message, but replying users will sometimes forget to do so.
You may also view and reply to messages via the archives.
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?
Some messages are automatically held in the moderation queue and must be manually approved by a mailing list admin:
These are:
The queue is usually checked once or twice a day, but on occasion several days may pass before someone checks the queue.
You should have received an email with the subject Your message to ffmpeg-user 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.
Perform a site search using your favorite search engine. Example:

You can ask for help in the official #ffmpeg IRC channel on Freenode.
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 500 kilobytes for the user lists and 1000 kilobytes for ffmpeg-devel. Please provide links to larger files instead of attaching them.

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.
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:
