Support CDM-Protected TS segments in HLS

[jhughes]

Issue description

I'm testing an HLS manifest with MPEG TS segments encrypted with CBCS with Widevine DRM.
On Android 8 and 8.1, Exoplayer playback stalls when it tries to play an encrypted MPEG TS segment.

The same manifest plays on Apple devices using Fairplay.
The same video repackaged to use HLS Fragmented MP4 plays successfully.
According to the Supported Formats documentation, HLS MPEG TS and CBCS should be supported in Android 24+.

Reproduction steps

Play provided test content using the demo player for at least 10 seconds (The first encrypted segment occurs at 10 seconds)

Link to test content

Link to TS and FMP4 manifests provided in email.

Version of ExoPlayer being used

Exoplayer 2.7.0

Device(s) and version(s) of Android being used

Tested with Pixel XL (Android 8.0) and Pixel (Android 8.1)

A full bug report captured from the device

Bug report for Pixel XL provided in email.

Subsample encryption in HLS+TS is not yet supported, only fMP4. I am going to use this to track this.

Hi All,

Any update here? The Widevine for HLS spec lists HLS+TS support included in Android N & O but it doesn't appear Exoplayer supports it. Does Exoplayer plan to add support or are you just settling on CMAF/fMP4?

[AquilesCanta]

There are no updates here, and it's not on our roadmap yet, unfortunately. By the way, what's the "Widevine for HLS spec "? Can you point me to it?

[sargeway]

The spec predates this thread and my contacts on the Widevine team believed Exoplayer already had the HLS+Widevine/cbc+TS support as described in version 1: https://storage.googleapis.com/wvdocs/Widevine_DRM_HLS.pdf.

Apologies, I misunderstood your previous comment. For the time being, our only support for CDM/DRM (Widevine, Playready) in HLS is with CMAF. For Transport Streams, only full segment encryption is supported.

@AquilesCanta

Excuse me but I'm planning to do PlayReady for HLS, your explanation seems to be like ExoPlayer already support them. Could I know where I can see the specifications of ExoPlayer for PlayReady on HLS?
Thanks in advance,

Hi @tehokang, this falls outside the scope of this issue tracker. I'd look into the microsoft docs for this.

According to https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/HLS_Sample_Encryption/Encryption/Encryption.html#//apple_ref/doc/uid/TP40012862-CH2-SW6， We try to Implement this feature。

The biggest adjustment is in H264Reader， Audio decryption successfully and playback
perfect， but video always has some flaws。Video playback smoothly and having mosaic appear occasionally。In strict accordance with the requirements of the analysis NAL units of type 1 and type 5，mosaic reduced to 1%~5%。

Is there any suggestion or train of thought that can solve Mosaic thoroughly excuse me？
