Here is the command line I used :

ffmpeg.exe -loglevel error -sn -i "D:\temp\source_movie.mp4" -map 0:v:0 -map 0:a:0 -acodec

and here are the technical infos, displayed by the program, in the DOS window :

Although the avi container supports the X265 codec this is merely 
because it is not really critical about what Codec is used, By design 
avi has many limitations for modern Codecs. You cannot use B-frames for 
example and many of the other advantages of the HEVC format cannot be 
used in this ancient container format. Remember the avi container dates 
from the early 1990's when X265, X264 or any other modern codec did not 
exist yet! Use avi for the Codecs of that era and youĺl be fine! (xvid, 
divx etc.)


So please use a modern container format for X265 encoded video, such as 
MP4 or MKV. They are much more efficient and allow full use of all X265 
features.

Thanks. I continued to work (play) after posting and it appears that I’ve found 
an acceptable workaround for x264. Now I’m trying “-r 29.97” or "-r 30” before 
input and “-fps_mode cfr” before the filtergraph. That prevents the crash and 
delivers pretty decent av sync, except that there’s an offset for the audio 
(it’s about 1200 ms late). But audio offset is pretty easy to correct, as long 
as the duration is right. I normally use a HEAD version of ffmpeg provided by 
Homebrew, but I wanted to make the environment as simple as possible to ask for 
help. I’ll go back to HEAD, I guess. I’m just a hobbyist. I would prefer to use 
x265, but the rest of my entertainment system isn’t yet compatible. Hope your 
libaom problem gets some attention soon.

And how can I get these infos ?

Re: [FFmpeg-user] Segmentation fault for two-pass libx264, but not two-pass libx265

2024-02-27 Thread Ferdi Scholten

I believe this should be a viable routine for two-pass encoding using 
libx264, but it fails, as shown. A similar command to encode the same 
video source file using libx265 with Matroska output is successful, so I 
don’t think the source file is the culprit. Both the x264 and x265 
encoding report 1475 frames encoded. Please help. Thanks.
