Bento4 mp4dash to encrypt Dolby Vision MP4 video with Playready does not play

I use mp4dash to encrypt my MP4 Dolby Vision video with Playready. The video cannot play because the payload data at the "mdat" box is bad. The first 4 bytes of the payload data is supposed to be the size of the payload. Currently the size number is too big so the data got rejected. When I use mp4dash with MP4 video without Dolby Vision and encrypt with Playready, video can play fine. The data at the box "mdat" is good, the first 4 bytes of the data has the correct size.

So I have to conclude that may be mp4dash does not work correctly with Dolby Vision + Playready.

Is your video larger than 4GB? In that case, the mdat box should use the 'long' form, which the tools should do automatically for you. Can you share the output of mp4dump for the file that doesn't play?

Hi Gilles,

Thanks for your reply. I have attached the mp4dump output. My MP4 video file is 427984124 bytes which is less than 4GB. My code tries to read and send the data at “mdat” but it does not think data is correct. May be the data at “mdat” got encrypted by mistake?

Best regards

The mdat atoms here look fine. If mp4dump was able to show you all the fragments (each fragment has its own mdat), it means the mdat atom sizes are correct. If they were not, mp4dump wouldn't be able to continue to the next fragment.

Hi Gilles

Thanks for looking at my problem.

I have attached a hexdump of the MP4 file and some explanation, you will see what my problem is.

Thanks

This a hex dump of the Dolby Vision + Playready MP4 video file. If you look at the bytes after "mdat", you will see "69 de 77 02" which is not a valid payload size. I notice that the bytes in the "mdat" box change when the file gets encrypted. The Dolby Vision file before the encryption shows a valid size after "mdat" but the Playready file shows a bad size which means that "mp4dash" changed the content of "mdat"

Below is a hex dump of a Playready file without Dolby Vision. The bytes after "mdat" show "00 00 00 06" which is a valid size (=6). I notice that for the unencrypted MP4 file without Dolby Vision and the Playready file without Dolby Vision, all the bytes in the "mdat" box do not change, they stay the same with or without encryption.

The size of an atom appear before the atom type. Here, the size of mdat in the Dolby Vision example is 00 03 9e 3b (237115 bytes) and 01 06 91 e2 (17207778 bytes) without Dolby Vision.

Hi Gilles,

I think the size I have problem with is the size of the frame to be sent.

The size you refer to is the size of the mdat box. The mdat box has many frames inside, each frame has different size.

If you look at the hex dump, for the Non-DolbyVision Playready file:

01 06 91 e2 (size of mdat) 6d 64 61 74 ("mdat") 00 00 00 06 (size of frame to be sent) 4e 01 81 01 0f 80 (bytes to be sent, number of bytes is equal to size above) 00 00 00 10 (size of frame to be sent) 4e 01 00 06 80 0a fc 78 00 06 01 03 04 00 07 80 (bytes to be sent) ............ (more frames)

Now look at DolbyVision+Playready hex dump:

00 03 9e 3b (size of mdat) 6d 64 61 74 ("mdat") 69 de 77 02 (size of frame to be sent, number is too big, my code will reject this frame)

HI Gilles,

I have attached another document showing the hexdump content of the same Dolby Vision file which is not encrypted. If you compare with the same Dolby Vision file +PLayready , you will see that the unencrypted file has good data in the box "mdat".

You can find MP4 video with Dolby Vision at this link:

https://developer.dolby.com/tools-media/sample-media/video-streams/dolby-vision-streams/

If you can use "mp4dash" to encrypt the Dolby Vision video, it will help.

If you can play the file with your player then it means that I did something wrong.

If you cannot play the file then we are seeing the same problem.

I am using Bento 4 version Bento4-SDK-1-6-0-634.x86_64

Thanks

I have here the hexdump for the same Dolby Vision file but this one is not Playready encrypted. As you can see, the content of box "mdat" looks good. Since the content of the same Dolby Vision file with Playready at the box "mdat" is bad, I have to conclude that may be "mp4dash" encrypts the "mdat" content, it should not touch "mdat".

I now understand what you mean. What you're referring to here are the NAL units that are part of the video data. NAL units have a size prefix followed by some type information and a payload. The size may be encoded with 1, 2 or 4 bytes. In your case here, a 4-byte NAL unit size encoding is used. The problem you're seeing is that mp4encrypt, unfortunately, doesn't detect Dolby Vision as being NAL-unit based, so it is encrypting the entire data payload, not as a sequence of NAL units (in which case the NAL unit headers would be left in the clear). I have fixed that now, so that Dolby Vision is properly detected when encrypting, and thus will be encrypted like other NAL-unit based formats. I'll push a new pre-compiled build soon. In the meantime, you can try it by building from source

HI Gilles,

This is awesome, you save my life.

I appreciate your help very much. I am very surprised that someone helps me quickly after I posted my problem

I spent many weeks thinking this is my problem.

How do I know when and where to get the updated Bento4?

Thanks

The updated code is already on the master branch on GitHub. For the pre-compiled binaries, they'll be at the usual location: https://www.bento4.com/downloads/ soon (it will be Version 1.6.0-636 or later)

HI Gilles,

I tried the new Bento4 version 636 that you just changed.

It looks like command "mp4dash" is working differently now.

"mp4dash" used to split the MP4 video into audio file and video file. Now I only see video file, there is no audio file.

Please check

Thanks

mp4dash should work exactly the same as before. Can you run mp4dash with the -d and -v options and share the output?

Hi Gilles,

Below is output of "mp4dash" for Bento4 version 636.

As you can see, only "video" sub-directory is generated in the "output" directory, there is no "audio" sub-directory.

I used Bento4_SDK-1-6-0-634 before, it gave me both audio and video directory.

Thanks

mp4dash should work exactly the same as before. Can you run mp4dash with the -d and -v options and share the output?

From the output here it looks like there's no audio track in your input file. Can you share the output of mp4info and mp4dump with the same file?

Hi Gilles,

I have attached the mp4info and mp4dump of the original DolbyVision file (not encrypted) and the Dolby Vision fragmented file (generated by "mp4fragment" from original unencrypted file).

I can see the problem: the original file shows 2 tracks (video and audio) but the fragmented file shows only 1 video track. It looks like this is a bug with "mp4fragment".

Thanks

I found the issue. The Dolby input file you're using has fixed-size audio samples, which lead mp4fragment to believe that the audio track had 0 samples. I'm not sure why I had not encountered this case before. I will fix it ASAP.

Hi Gilles:

Thanks for the explanation.

I still do not understand why I do not see this problem with mp4fragment when I was using the older version of Bento4 (version 634) on the same Dolby Vision file. Please clarify for me.

Thanks

While fixing a potential overflow issue found by a fuzzer (issue #511 ) , I introduced a bug where files with constant-size audio samples were not handled correctly anymore.

Hi Gilles,

I still have problems playing the Dolby Vision Playready video.

My code still has problem parsing the Dolby Vision Playready file generated by mp4dash.

It looks like the number of subsamples is 2 which is giving me problem, video cannot play.

On a non-DolbyVision file, the mp4dash command with Playready gives me a file with number of subsamples=1, the video plays fine.

I do not understand this "subsample" well. Do you have any documents on this?

Thanks
