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.

<p>Sometimes you may want to temporarily stop receiving all mailing list

|
||
|
|
</p>
|
||
|
|
<ol class="enumerate">
|
||
|
|
<li> Go to the <a class="url" href="https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-user/">ffmpeg-user mailing list info page</a>
|
||
|
|
|
||
|
|
</li><li> Enter your email address in the box at very bottom of the page and click the
|
||
|
|
<em class="emph">Unsubscribe or edit options</em> box.
|
||
|
|
|
||
|
|
</li><li> Enter your password and click the <em class="emph">Log in</em> button.
|
||
|
|
|
||
|
|
</li><li> Look for the <em class="emph">Mail delivery</em> option. Here you can disable/enable mail
|
||
|
|
delivery. If you check <em class="emph">Set globally</em> it will apply your choice to all
|
||
|
|
other FFmpeg mailing lists you are subscribed to.
|
||
|
|
</li></ol>
|
||
|
|
|
||
|
|
<p>Alternatively, from your subscribed address, send a message to <a class="email" href="mailto:ffmpeg-user-request@ffmpeg.org">ffmpeg-user-request@ffmpeg.org</a>
|
||
|
|
with the subject <em class="emph">set delivery off</em>. To re-enable mail delivery send a

|
||
|
|
<h3 class="section">5.8 Why is the mailing list munging my address?</h3>
|
||
|
|
|
||
|
|
<p>This is due to subscribers that use an email service with a DMARC reject policy
|
||
|
|
which adds difficulties to mailing list operators.
|
||
|
|
</p>
|
||
|
|
<p>The mailing list must re-write (munge) the <em class="emph">From:</em> header for such users;
|
||
|
|
otherwise their email service will reject and bounce the message resulting in
|
||
|
|
automatic unsubscribing from the mailing list.
|
||
|
|
</p>
|
||
|
|
<p>When sending a message these users will see <em class="emph">via <mailing list name></em>
|
||
|
|
added to their name and the <em class="emph">From:</em> address munged to the address of
|
||
|
|
the particular mailing list.
|
||
|
|
</p>
|
||
|
|
<p>If you want to avoid this then please use a different email service.
|
||
|
|
</p>
|
||
|
|
<p>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.

</p>
|

<ul class="itemize mark-bullet">
|
||
|
|
<li>Always show your actual, unscripted <code class="command">ffmpeg</code> command and the
|
||
|
|
complete, uncut console output from your command.
|
||
|
|
|
||
|
|
</li><li>Use the most simple and minimal command that still shows the issue you

are encountering.
|
||

|

|
|
</li><li>Provide all necessary information so others can attempt to duplicate

your issue. This includes the actual command, complete uncut console
|
||
|
|
output, and any inputs that are required to duplicate the issue.
|
||
|
|
|
||
|
|
</li><li>Use the latest <code class="command">ffmpeg</code> build you can get. See the <a class="url" href="https://ffmpeg.org/download.html">FFmpeg Download</a>
|
||
|
|
page for links to recent builds for Linux, macOS, and Windows. Or
|

compile from the current git master branch.

Also see <a class="ref" href="#What-is-top_002dposting_003f">What is top-posting?</a>
|
||
|
|
|
||
|
|
</li><li>Avoid hijacking threads. Thread hijacking is replying to a message and
|
||
|
|
changing the subject line to something unrelated to the original thread.
|
||
|
|
Most email clients will still show the renamed message under the
|
||
|
|
original thread. This can be confusing and these types of messages are
|
||
|
|
often ignored.
|
||
|
|
|
||
|
|
</li><li>Do not send screenshots. Copy and paste console text instead of making
|
||
|
|
screenshots of the text.
|
||
|
|
|
||
|
|
</li><li>Avoid sending email disclaimers and legalese if possible as this is a
|
||
|
|
public list.
|
||
|
|
|
||
|
|
</li><li>Avoid using the <code class="code">-loglevel debug</code>, <code class="code">-loglevel quiet</code>, and

|
|
<code class="command">-hide_banner</code> options unless requested to do so.
|
||
|
|
|
||
|
|
</li><li>If you attach files avoid compressing small files. Uncompressed is
|
||
|
|
preferred.
|
||
|
|
|
||
|
|
</li><li>Please do not send HTML-only messages. The mailing list will ignore the

HTML component of your message. Most mail clients will automatically
|
||
|
|
include a text component: this is what the mailing list will use.
|
||
|
|
|

|
|
</li><li>Configuring your mail client to break lines after 70 or so characters is

|
|
recommended.
