Vivaldi doesn't play videos

[flyx]

Hi folks,

I'm just trying out this browser. Sadly, it doesn't play any videos. I tested a bit with https://help.vivaldi.com/desktop/media/html5-proprietary-media-on-linux/ and got these error logs from vivaldi://media-internals:

For what I can see, the important part seems to be "UNREADABLE_INPUT, SFT_INVALID_STREAM", but I can't deduce what's going wrong there. I played around a bit with the flags enable-gpu-rasterization, enable-zero-copy, enable-gpu-rasterization and ignore-gpu-blocklist, but changing their values doesn't make any difference.

Video playback works fine in Firefox and Safari. I'm on macOS 11.1 x86_64. Is there something I overlooked?

What site are you trying on and is this one of the new M1 Macs, and are you trying the stable version of Vivaldi or one of the snapshots?

[flyx]

I am on Vivaldi 3.5.2115.87 (Stable channel) (x86_64). This is not an M1 Mac. And as I said, I'm testing on the Vivaldi HTML5 testing site linked above, but also tried directly loading an mp4 file from my local file system, which doesn't work either.

[flyx]

@Gwen-Dragon Done. Hoping for this to get fixed since I do like this browser overall :).

[Chas4]

@flyx The test video in the Vivaldi help site played fine for me (macOS 11.1 (11.2 is out in the next few weeks) Vivaldi 3.5.2115.87 (Stable channel)

Do you have any extensions? Try downloading downloading the stable version again and installing it over the current stable (have to have Vivaldi closed for this). Looks like it is having trouble loading the video decoder.

Here is what I see after playing the video one time:

@Chas4 I did disable all extensions for testing and re-installed Vivaldi.

Interesting that your log shows a PassThroughVideoDecoder which is not even mentioned in mine.

I noticed that in vivaldi://gpu under Problems Detected, there is the following line:

Protected video decoding with swap chain is for certain Intel and AMD GPUs on Windows: 1093625
Disabled Features: protected_video_decode

This seems strange as it mentions Windows, not sure what to make of it. Chrome gives the same output at chrome://gpu but does play the video. So I did check Chrome's output when playing the video, and got

00:00:00.660	info	"Failed to initialize DecryptingVideoDecoder"
00:00:00.660	info	"Failed to initialize MojoVideoDecoder"
00:00:00.660	info	"Failed to initialize VpxVideoDecoder"
00:00:00.660	info	"Failed to initialize Dav1dVideoDecoder"
00:00:00.660	kIsVideoDecryptingDemuxerStream	false
00:00:00.660	kVideoDecoderName	"FFmpegVideoDecoder"
00:00:00.660	kIsPlatformVideoDecoder	false
00:00:00.660	info	"Selected FFmpegVideoDecoder for video decoding, config: codec: h264, profile: h264 main, level: not available, alpha_mode: is_opaque, coded size: [720,404], visible rect: [0,0,720,404], natural size: [720,404], has extra data: true, encryption scheme: Unencrypted, rotation: 0°, flipped: 0, color space: {primaries:BT470BG, transfer:BT709, matrix:SMPTE170M, range:LIMITED}"

So interestingly, Chrome is unable to do hardware-accelerated decoding too and uses ffmpeg. I tried to figure out what Firefox does as well, but didn't find a way to do it. Neither for Safari.

@flyx What model Mac are you using?

[flyx]

@Chas4 You brought me on the right track. After seeing that Chrome doesn't use hw acceleration, I did some digging and found out that the problem is my iGPU which was disabled in UEFI (yeah this is a hackintosh) because apparently macOS promotes the iGPU for hw acceleration even in the presence of a dGPU.

I apologize for bringing this issue here when the error cause is obviously out of scope. I am unsure whether the error can occur in more valid environments and thus whether getting on par with Chrome's handling of the situation could be desirable.
