Problem with video 5

I am trying to configure my site to use HTML 5 video. Mp4 files are served from S3. My MIME type is correct and the URL is correct. This does not work. The only thing I can think of is the wrong codec.

Here is my code:

<video width="320" height="240" controls>
<source src="{url}"  type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
</video>

Now, as I understand it, the audio codec is always the same. mp4a.40.2. The video is encoded as basic, but according to http://wiki.whatwg.org/wiki/Video_type_parameters#MPEG-4 , the last two characters of the video codec in my code 1Eare a variable.

Are there any wrong characters to make the video not work? If so, how do I find the correct settings?

It’s not easy for me to wrap my head around this stuff. Thanks for any help you can provide.

The idea behind the video codec information is that your browser will not download the video if it cannot play it. ( found that here ) Therefore, I think that even with the wrong but general avc level (last 2 characters) it should load and play. I found this guide on how to detect and change the avc level using a hex editor. Megui obviously also works for this.

Try to remove the attribute type. If this makes it work, you have found a problem. Also check the actual HTTP header Content-Type.
