Body: <p>I have problem with ffmpeg properly recognizing a video encoded with Microsoft Fast Mpeg 4v2 codec. Apparently it's a software codec. VLC plays the video fine. The codec reported by VLC is:</p>
  <pre><code>Codec: MPEG-4 Video (mp4v)
  Video resolution: 8192x8192
  Frame rate: 7.549296
  </code></pre>
  <p>Additional info that MediaInfo reports:</p>
  <pre><code>Codec ID: mp4v-20
  Bit rate mode: Variable
  Minimum frame rate: 3.429 FPS
  Maximum frame rate: 24.000 FPS
  </code></pre>
  <p>However, when trying to read this stream with ffmpeg, it reports the following errors:</p>
  <pre><code>$ ffmpeg -v error -i Somefile_01_31_17_08_21.mp4 -f null -

  </code></pre>
  <p>ffmpeg -codecs doesn't show it as one of the codecs. <a href="https://superuser.com/questions/118212/what-is-mp4v-and-mp4a">This question</a> suggests that this is a standard mp4 codec supported by ffmpeg module in VLC. How is it that ffmpeg module in VLC decodes the video properly but ffmpeg itself doesn't? Any idea how to convert this video to h264/h265?</p>

Title: How to convert Fast Mpeg 4v2 (mp4v) with ffmpeg
UserDisplayName: Greg
ThreadText: # How to convert Fast Mpeg 4v2 (mp4v) with ffmpeg
  
  (Asked by: username_0 on 2021-02-06)
  
  I have problem with ffmpeg properly recognizing a video encoded with Microsoft Fast Mpeg 4v2 codec. Apparently it's a software codec. VLC plays the video fine. The codec reported by VLC is:
  
  ```
  Codec: MPEG-4 Video (mp4v)
  Video resolution: 8192x8192
  Frame rate: 7.549296
  
  ```
  
  Additional info that MediaInfo reports:
  
  ```
  Codec ID: mp4v-20
  Bit rate mode: Variable
  Minimum frame rate: 3.429 FPS
  Maximum frame rate: 24.000 FPS
  
  ```
  
  However, when trying to read this stream with ffmpeg, it reports the following errors:
  
  ```
  $ ffmpeg -v error -i Somefile_01_31_17_08_21.mp4 -f null -

  ```
  
  ffmpeg -codecs doesn't show it as one of the codecs. [This question](https://superuser.com/questions/118212/what-is-mp4v-and-mp4a) suggests that this is a standard mp4 codec supported by ffmpeg module in VLC. How is it that ffmpeg module in VLC decodes the video properly but ffmpeg itself doesn't? Any idea how to convert this video to h264/h265?
