Issue and steps to reproduce the problem

Packager Command:

Extra steps to reproduce the problem? (1) i am executing the the command for running the pacakger (2)$ packager input=/media/test.mp4,stream=audio,output=/media/audio.mp4 \ input=/media/test.mp4,stream=video,output=/media/video.mp4 \ --mpd_output /media/test.mpd

@priyanshugupta27 Could you run stat /media/* so that we can see what permissions all the files in /media has?

There is not much we can do with just the error message and the command. The packager can't find /media/test.mp4. So I want to make sure that it is in fact in the directory with the correct permissions.

@vaage I again rechecked and found that the file name was wrong. Now I have corrected the file name and successfully able to do packaging for the free content. But now i am facing one more error as mentioned below: Error while running the command using –pssh value [0302/110327:ERROR:raw_key_source.cc(110)] --pssh argument should be full PSSH boxes.

Can you please help me with this error?

[vaage]

@priyanshugupta27 I would be happy to help, could you provide me with the full command you are running?

[priyanshugupta27]

@vaage Today I tried and able to resolve the error with below mentioned steps:

1) For the pssh error we set up the environment according to the below link: https://github.com/google/shaka-packager/tree/master/packager/tools/pssh

2) After the setup we created the complete pssh box with system ID: ./pssh-box.py --widevine-system-id --pssh-data $(echo 'CAESEJlz1v1lMkV5uWldyEVq8cciEUFpcnRlbFRlc3RDb250ZW50' | xxd -r -p | base64) –hex

3) Replaced the encryption tag with “enable_raw_key_encryption” as suggested by David and provided the pssh value generated in the step 2: packager input=/media/encryption.mp4,stream=video,output=encryption-short.mp4 --clear_lead 0 --output_media_info --profile on-demand --enable_raw_key_encryption --key_id=9xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7 --key=exxxxxxxxxxxxxxxxxxxxxxxxxxxxxxd --pssh 000000217073736800000000EDEF8BA979D64ACEA3C827DCD51D21ED00000001CA

4) Create the mpd file mpd_generator --input "encryption-short.mp4.media_info" --output "encryption-short.mp4.mpd"

It will be really helpful if you can review these steps and confirm that the steps I followed are correct. Thanks

[vaage]

@kqyang Do these instructions look correct to you?

@priyanshugupta27 I haven't done much with PSSH, so I can't tell if anything is wrong, but the fact that mpd_generator is in the last step, it makes me feel that these could be outdated.

[priyanshugupta27]

Using mpd_generator I am successfully able to create the required mpd

[kqyang]

@priyanshugupta27 Yes, the steps are correct. I am glad it works out for you. You may merge 3 and 4 into a single step, i.e.

packager input=/media/encryption.mp4,stream=video,output=encryption-short.mp4 --clear_lead 0 --profile on-demand --enable_raw_key_encryption --key_id=9xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7 --key=exxxxxxxxxxxxxxxxxxxxxxxxxxxxxxd --pssh 000000217073736800000000EDEF8BA979D64ACEA3C827DCD51D21ED00000001CA --mpd_output encryption-short.mp4.mpd

mpd_generator is not actively maintained (for now, though we have plan to improve it), e.g. it does not support HLS playlist output. We recommend generating manifests directly using packager, unless there is a reason to use mpd_generator.

[priyanshugupta27]

Thank you for the confirmation @kqyang . My requirement is for DASH not for HLS and for future purpose I will keep in mind not to use mpd_generator. @vaage Thank you for your support. Can you also confirm what is the format for KEY ID and KEY DATA?

[vaage]

@kqyang Could you provide an explanation of the format of KEY ID and KEY DATA?

[kqyang]

They must be hex strings. These two arguments are going to be deprecated. Please see https://google.github.io/shaka-packager/html/tutorials/raw_key.html#synopsis for the updated arguments.

[priyanshugupta27]

Thanks @vaage @kqyang for your quick support. Issue is resolved and the doubts are clear for now. Closing the ticket.
