Could you try the latest nightly build https://avidemux.org/nightly/win64/ ?
There are portable versions (.zip)

I give up!

On another PC I have 2.7.8 which takes about 3 Minutes for the decoding. I copied those settings to 2.8.1 and it did not make a difference. Also tried all the OpenGL, QT etc. options and decoding did not change from the 8 Minutes.

So I tried 2.8.0 - and that takes about 2 Minutes. I will keep using that.

Rebonsoir ,
J'ai trouvé mon problème : le film est corrompu à cause d'un mauvais assemblage entre 2 vidéos qui a provoqué la désynchronisation de la vidéo , je ferai plus attention à ça la prochaine fois.

Bonjour

J'utilise Avidemux pour couper des séquences indésirables sur des vidéos MPEG TS , du coups je dois réencoder afin de conserver la synchronisation des images de la vidéos.
Je réencode en NVIDIA H264 , sortie vidéo en mp4 . Il y en a pour 30 min de réencodage pour 1 heure 30 de vidéo.
Arrivé à 93/100 , Avidemux ne répond plus , je peux attendre 30 min , ça ne change rien .
Je force la fermeture de Avidemux et essaie d'ouvrir le fichier réencodé , lecture impossible, ce qui ne me surprend pas.
Je refais une tentative en réencodant en mepg xvid h 264 : c'est pareil , ça plante toujours à 93/100.
Quelqu'un a-t-il la solution ? Merci

This means, HW accelerated decoding is disabled. It can be enabled in Avidemux Preferences in the HW accel. tab.

Enabling OpenGL requires restart of Avidemux, did you do that?

If probing OpenGL features results in a crash on Avidemux startup, this points to a broken graphics driver. If you are on Windows, please provide admlog.txt (from %localappdata%\avidemux) from such a crash and try to use the "DXVA2" display.

Hi, seems 2.8.0 was already wiped from the PC when I installed the latest. For the decoder option I see only "Swap U and V". Output is copy/copy and format is MKV. I did an "Enable OpenGL", but AviDx crashed.

Is it possible to use Avidemux for frameserving to NLE apps like Vegas Pro?

For ex;
Currently Vegas Pro can't open videos encoded with AV1 and VP9 codecs while Avidemux can.
It would be awesome if Avidemux could frameserve to Vegas Pro.

Sorry for the late update, work has been horrendous!

Now, having tried again, and not doing it half-asleep, i have better results that aren't OOS.
No doubt i got it wrong, especially doing something first-time, but now all good.
A massive thank you to all that helped, its appreciated

The usual offenders.

Hw accelerated decoder and encoder are quite powerful in this processor. Are you sure you used the same settings with 2.8.0? I am not aware of any changes which might have caused such a major slowdown of PTS reconstruction. Could you please provide admlog.txt from loading the same AVI/H.264 video in 2.8.0 and in 2.8.2 (the latest nightly)?

Quote from: eumagga0x2a on December 05, 2022, 09:51:26 PMWhoever puts H.264 with frame reordering (with B-frames) into an AVI container, does a grave disservice to humankind.

Well, it's from an online TV recorder. They have MP4 too, but in much lower resolution, unfortunately.

Quote from: eumagga0x2a on December 05, 2022, 09:51:26 PMPlease check that hardware accelerated decoding is available and enabled. Depending on video resolution, hardware and hwaccel API (depending on platform, VDPAU, VA-API, VideoToolbox or DXVA2), it can vastly increase decoding speed. If the CPU is very powerful, enabling multi-threaded decoding in libavcodec (in Avidemux Preferences) and disabling decoding in hardware may be faster, however.

I have a 6th gen i3 without extra GPU. So I presume I am stuck with what I have.
