DRM protected content only plays when in remote debugjs mode

[sanjeevghimire]

I have a video streaming app and plays DRM protected content. The video only plays when i debug mode only. If I turn off the debug mode the video doesn't play and displays, video not available.

Which player are you experiencing the problem on:

• iOS

[EyMaddis]

If you override the getLicense() method, the spc variable is not available outside of debugging mode (because of a bug).
Use the third parameter for a base64 representation.

@EyMaddis I tried adding the third parameter also and its not playing. Is there a sample I can look into?

[EyMaddis]

Unfortunately not, I also do not use this right now. I was just trying to implement my DRM service (Axinom) and was hacking around with manually decoding the base64 (third parameter). However, for me the fix was to avoid getLicense and only set the header 'Content-Type': 'application/octet-stream'.

Maybe you can post your getLicense and I can take a look.

Edit: Check if your getLicense code is used at all. See here: https://github.com/react-native-community/react-native-video/pull/1445/files#diff-2a97390647ad4fd466bccc2c92e7864eR236

Another edit:
I found my next-level hackery license code that is unnecessary since the header solved all of this.
Maybe this can help you, however I patched react-native video on the line I linked above:

getLicense: async (
          spc: string,
          contentId: string,
          spcBase64: string
        ) => {
          try {
            console.warn('sending license request!', spcBase64)
            const blob = Buffer.from(spcBase64, 'base64')
            // const blob = Buffer.from(spcString, 'ascii')
            console.warn('sending license request!', blob)
            const license = await fetch(fairplay.licenseUrl, {
              method: 'POST',
              headers: {
                'Content-Type': 'application/octet-stream',
              },
              body: blob,
            })
              .then(response => {
                console.warn('got license as blob!')
                return response.blob()
              })
              .then(response => {
                // React Native does not properly handle
                console.warn('blob2base64')
                return new Promise((resolve, reject) => {
                  const reader = new FileReader()
                  reader.onload = () => {
                    const dataURL = reader.result
                    console.warn('Got DATA URL!')
                    resolve(
                      // @ts-ignore
                      dataURL.replace(
                        'data:application/octet-stream;base64,',
                        ''
                      )
                    )
                  }
                  reader.onerror = err => {
                    reject(new Error('could not turn '))
                  }
                  reader.readAsDataURL(response)
                })
              })
              .catch(error => {
                console.error('Fairplay error', error)
              })
            return license
          } catch (e) {
            console.error('could not get license', e)
          }
        },```

This is based on the approved PR: feature/ios-drm-support

getLicense: ({ spc, contentId, spcBase64 }, props) => {
              console.log("spc", spc);
              console.log("spcBase64", spcBase64);
              return fetch("https://fp-keyos.licensekeyserver.com/getkey/", {
                method: "POST",
                headers: {
                  "Content-Type": "application/x-www-form-urlencoded",
                  customdata: xml
                },
                body: `spc=${spcBase64}&assetId=${contentId}`
              }).then(r => r.text());
            }

Then go into your node_modules folder, and find this line:
https://github.com/react-native-community/react-native-video/pull/1445/files#diff-2a97390647ad4fd466bccc2c92e7864eR236

Then change it to if (data), restart the bundler and try again. Xcode should now log something for spcBase64 in the xcode console.

yep that fixed it. thanks @EyMaddis
