TVBR would be an uncapped VBR, ala just using --crf or --qp without any profile/level VBV limitations. Potentially slightly better sound quality, and preferable for file-based playback. Since there's only so high a bitrate can go with a codec, in practice there's not likely to be that much a difference unless the constrained bitrate is quite constrained. |

1- Opus exists. 2- Audio codecs don't need hardware (accelerated) support. Platform-level support is not an absolute requirement either. Apps can add software decoding for any audio codec without a noticeable downside like too much battery drainage (assuming no unusual complexity requirements). There is a reason why xHE-AAC is not that exciting. --- There is a third fact that HE-AAC is shit for anyone who has any respect for their ears. But let's not get into that.

[QUOTE=kurkosdr;1999619]As long as xHE-AAC stays away from video broadcast (DVB and ATSC), I am happy. Streamers can always encode an HE-AAC fallback for older devices and serve accordingly (I don't like the idea of throwing away good smartphones in the name of "replacement cycles"/planned obsolescence, I still use my Nexus 5 and 5X as secondary phones).[QUOTE]
xHE-AAC is supported on really old phones. As long as it can upgrade to Android 9 or iOS 13, the decoder is there. That's all the way back to the iPhone 6s for Apple. Android updates are up to the whim of the OEM, of course, but five years is enough to get a pretty complete ecosystem refresh for mobile. Certainly most streaming apps don't support OS versions earlier than those. But yeah, for broadcast broadcast, introducing new codecs is fraught and generally part of a massive shift. ATSC 1.0 to 3.0, for example (which still exists more in theory than practice). DVB seems to be able to get an update in more than once every few decades . Quote:

MPC-HC 2.2.0 by clsid2 now supports VVC decoding natively, hooray!
https://github.com/clsid2/mpc-hc/releases Probably uses native FFmpeg decoding which is far from being fully/properly optimized (vvdec is 2-3 times faster) but it's still freaking amazing. |

I'm not sure if I'm in the correct thread, but I'm trying to use this VCC Encoder:-
https://github.com/Disa-Kizonda/VVC-GUI-Encoder And after setting up the "Ready to Use Pack", and loading a file, I get this error:- Code:
'ffmpeg_vvceasy.exe' is not recognized as an internal or external command, operable program or batch file. Exception in Tkinter callback Traceback (most recent call last): File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.3568.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1892, in __call__ return self.func(*args) File "C:\Users\Geoff\Downloads\VVC_GUI_Encoder\VVC_GUI_Encoder.py", line 10, in SelectButton imgone=Image.open('temp.jpg') File "C:\Users\Geoff\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\PIL\Image.py", line 3277, in open fp = builtins.open(filename, "rb") FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Windows\\System32\\temp.jpg' 'C:\\Windows\\System32\\temp.jpg' this doesn't look right, either... double \\ ??? |

Regarding the double backslash: I am almost sure this is not the problem, just a required convention on Windows; but expecting a temporary JPEG file in Windows\system32 is an issue: No application should try to create files there. I guess the converter searches there for a file it did not find elsewhere, maybe because a verbose path to that file is missing. Searching alternatively in the system directory of Windows may be fine when looking for required DLLs, but not when looking for general data files.

Looking for "VVC encoder GUIs", I also found this project which might be interesting for some Linux users:
aviator - https://github.com/gianni-rosato/aVVCator A Flatpak-first easy-to-use GUI for encoding with VVenC & aac. |

Please exercise extra caution when using random github projects or anything you download from the Internet.
In a perfect world you either run such things under a separate limited user account (given your system is 100% up to date/still supported/fully updated), or better yet in a virtual machine (virtualbox, vmware, qemu/kvm, etc), again under a limited user account. The same applies to various PPA/COPR/AURs/whatever. |

And now FFmpeg 7.0 as well!
"A new major release, FFmpeg 7.0 "Dijkstra", is now available for download. The most noteworthy changes for most users are a native VVC decoder (currently experimental, until more fuzzing is done)" Quote:

It's weird, Qualcomm boasts about Adreno being able to decode 4K 60fps VVC video in real time in software mode on Snapdragon 8 Gen 2.
Meanwhile aside from MX Player no one seems to be interested. |
