title: How to set output as azure blob in FFMPEG command
body: <p>In my Queue trigger Azure Function, I am resizing video using FFMPEG command.</p>
  <pre><code>subprocess.run([&quot;ffmpeg&quot;,  &quot;-i&quot;, 
                             &quot;input.mp4&quot;,
                              &quot;-filter_complex&quot;, &quot;scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1,setsar=1,fps=25&quot;,
                              &quot;-c:v&quot;,&quot;libx264&quot;,
                              &quot;-c:a&quot;,&quot;aac&quot;,
                              &quot;-preset:v&quot;, &quot;ultrafast&quot;,
                              &quot;output.mp4&quot;],
                              stdout=subprocess.PIPE,
                              stderr=subprocess.STDOUT) 
  </code></pre>
  <p>Currently output will be write locally and use azure function local space. What I want that output file directly write to azure container as a blob. And not save it to locally as function has less space and for resizing its required more space which causing issue.</p>
  <p>How can I achieve this?</p>
