Video uploaded via api cant be played

[Baaka]

I tried to upload a mp4 video that is above 150mb with the session api and I successfully uploaded it to dropbox without a single error, but the video just wont play. Accessing the video via a shared link with raw=0 results in the browser not playing the video because the file is in a not supported video format.

Does anyone know why this is happening?

A good first step for debugging this is to check if the file was uploaded correctly (e.g., to check if there were any bugs in the upload session implementation, for instance, if the pieces were upload out of order or anything like that).

Does the uploaded file have the exact correct file size? You can also try to verify it by downloading it again, or by checking the content_hash value ( https://www.dropbox.com/developers/reference/content-hash ).

If the file is correct, it may just be a matter of the browser not supporting the video format/codec and so not being able to play it at all.
