RTBF: Videos without sound

Cappal

Hello, Starting today, I’ve noticed that the videos I download from the RTBF Auvio replay site have no sound. Could you please check this? I’ve tried both the new and old versions, and unfortunately, it’s the same. https://auvio.rtbf.be/

It was fixed 5 months ago with 7009 -> here

I tried with SF 7030, 7025 and 7011 (mp4 + MKVToolnix) ..
.. and always Processing fails for me (_StartShakaPackagerDecrypt)
[Critical]: [DC.Base] DecryptBinarayFile failed.

Hello Germania. I have the impression that RTBF updates the DRM protections regularly (once a year?), which is causing these failures…

Germania

I tried again with fresh login, different vpn and movie instead episode ..
.. but nothing changed - processing never ends:

If I check content in Temp\outputTemp\Youtube Plus\ ..
.. the video is merged and decrypted (vt_00)

.. but the audio decryption fails

Cappal

Yes Germania, at my place too, the video is OK, but there’s no sound…

Fin Mai, téléchargement de video sur AUVIO était OK. Mais depuis ce week-end, impossible de télécharger.
La vidéo n’apparait pas, on reste bloqué sur un écran noir

Despite recent updates (the latest being 7.0.3.5), downloading from the platform https://auvio.rtbf.be/ is still impossible… Please look into this.

I can only confirm that it remains unchanged ..

.. but a new topic will not change the problem.

Cappal

Hello Germania. Previously, you could at least download the video without sound, but now SF can’t even analyze the source and the stream anymore; it’s even worse! SF keeps analyzing but gets nowhere, and finally gives us the message I quoted earlier.

That was just for the feedback ;-)

Cappal now SF can’t even analyze the source and the stream anymore

Don’t you see the “Auvio” source in my image above?

You can certainly believe me when I wrote: “remains unchanged”

The video still arrived correctly for me:

btw: I can’t detect a requested title in your log

Hi there,

Please post a LOG file.

Germania

From my manual tests I know that I get errors with decrypting using mp4decrypt ..
.. but it works fine with decrypting using shaka packager (regardless of whether it’s mp4)

The merged (encrypted) Audio file show me this Conformance errors:
File size is less than expected size CMAF does not permit USAC UsacConfig channelConfigurationIndex 0, permitted values are 1 and 2

With manually audio dl using yt-dlp I get also the last error ..
.. but the shaka packager command line from SF log works fine

With SF the same command line fails:
[CefMedia] [0704/143739:INFO:mp4_muxer.cc(175)] Skip stream '.. /outputTemp/Youtube Plus/ ... /Period_00/Audio_00/at_00.mp4' which does not contain any sample.

So the problem actually occurs beforehand ..
\Temp\outputTemp\Youtube Plus\ … \Period_00\Audio_00\at_00
.. is larger than my manually dl from encrypted audio with yt-dlp - and I don’t know why

Germania

Cappal And what was the problem, then?

I had already written that 15 days ago:

Germania Audio_00\at_00 .. is larger than my manually dl

-> the download size of the audio was incorrect.

The correct decryption key was always in the log
and worked with the video using SF, as well as
with the audio after my manual audio download.

Apparently, the problem was solved by:

StreamFab 7.0.4.0 Changelog
New: Optimized the download engine,
improving download speed by approximately 20%

Hi,
Is RTBF auvio (belgium channel) support effective on StreamFab please?
CU,

Germania

akashathot Is RTBF auvio (belgium channel) support effective on StreamFab please?

The video merges without issues, but the audio decryption fails ..
.. which is why “Processing” never finishes - see above

akashathot

True. Download seems to work (sometimes, not always), but “Processing” is ongoing.
