You can use the iframe technique from the magic buttons app.
create a formula rich text field, [iframe], and give it the following code: "<video src = " & URLRoot() &"up/"& Dbid() &"/a/r"& [Record ID#]&"/e9/v0\" width=\"500\" controls>\n</video>"
rename the [attachment] field to whatever yours is named.
create a report link field, [link], and set the field relationship as follows:
In my example the app name is QB Developer Resources and the table name is Tests; set the relationship to match your app and table name.
Next add the link field to your form and it will display the video and the user can play the video on the form.
