Avidemux Forum

I tried a few times to paste in the file details from AviDemux and MediaInfo, but I was getting this AntiSpam error: "CleanTalk: *** Forbidden. Message seems to be spam. Anti-Spam by CleanTalk. ***"

I have a 854x426 H264 .mp4 video that plays onscreen in all of the Windows 11 players I've tried (Pot, VLC, WMP, MPC, etc.) as if it was 16:9, when the video was intended to be 4:3, since everything in the video is stretched horizontally (everything looks wider/fatter than expected). If I open POT Player and tell it to manually force the aspect ratio to 4:3 it displays fine.

Is there a way to use AviDemux to fix this? I don't need to change anything else about the video (audio, resolution, etc.), except to make it show onscreen correctly. I'm happy to change the container file format. I've tried using MKV Muxer output with Force Aspect Ratio (DAR) of 4:3, re-encoding to HEVC, and a few other things, but nothing fixed the issue yet. This is with the latest Windows development release 2.8.2, but I have the same issue with 2.8.1.

I'm new to video encoding and AviDemux. I have only used it to crop videos before this.

Bonjour,

J'utilise un avidemux master 20-01-2025, tout fonctionne très très bien, mais je ne peux pas compiler sans l'option "debug" donc j'ai un fichier idxb qui est créer a chaque utilisation.

Je sais qu'une telle demande est tres égoiste mais j'ai un  igp intel haswell donc directX 11 seulement, pas de vulkan et ffmpeg 7 ect..
Voila merci à Mean et eumagga0x2a pour leur travail.

Hi, I would like this feature as well. I would extend it to play in loop. I often create small clips from video and it would be game changer to see the clip looping before I export it.

Thanks

restore all gcc g++ and cpp now works, was linked to clang installing "clang-as-default", now works.
Thanks

Thank you, I'll continue this topic once I've got a chance to test myself.

Regarding AV1 support not detected, I'll look into providing an official VC++ nightly quering more GUIDs and maybe also other pixel formats just to understand what is going on. It would be lovely if you could provide admlog.txt generated by that build. However, one step at a time.

I do not have linux on this PC (only on raspberry PI), but if you want to run any tests, or instruct me what details to send I will be happy to help.

same error during compiling Handbrake:
lutil -lrt -lpthread -lm -ldl -lc -Wl,--end-group

for me it's not good this, must be:

Is this linker failure specific to building Avidemux with clang? Does building with gcc fail as well?

after installing this not works:
clang-as-default gdc-14 gdc-14-x86-64-linux-gnu libgphobos-14-dev libgphobos5 libpython3.13-stdlib python3.12-gdbm python3.12-tk python3.13 python3.13-gdbm python3.13-tk

try to remove and see if it's all ok
