Why does ffmpeg keep using more and more RAM and crash ?
29 décembre 2022, par József Márton KakasI am using the following command with ffmpeg to encode a video file using the libsvtav1 codec :
ffmpeg -i hevc.mkv -map 0:v:0 -c:v:0 libsvtav1 -preset 8 -crf 22 -format matroska av1.mkv.

However, ffmpeg is using up all of my available RAM and crashing. I have also tried using the libx264 codec, but the same issue occurs, although it happens more slowly. I have already allocated 12 GB of RAM to ffmpeg, but it still seems to be insufficient. How can I prevent ffmpeg from using all of my available RAM and crashing when using either the libsvtav1 or libx264 codecs ?


I have tried it on another VM, but the same issue occurs. Here is the full output of the program.

ErrorCode 1 while merging 2 videos
10 janvier 2023, par Stéphane de LucaI am trying to merge two videos but have an error code 1.


My command is as follows :


final command =
 '-y $commandPaths -filter_complex \'[0:0][1:0]concat=n=${paths.length}:v=1:a=0[out]\' -map \'[out]\' $outputPath';


I see the following error :




I/flutter (17343) : Stream specifier ':0' in filtergraph description [0:0][1:0]concat=n=2:v=1:a=0[out] matches no streams.




Not easy to understand what caused this as I am not familiar with the lib.


I saw in a so that someone had the issue caused by the tw videos not having the same size.


The logs are as follows :

I/flutter (17343): error 1


Therefore I tried to add a resize in the command without success as follows :.


final command =
 '$commandPaths -filter_complex \'[0:v]scale=1920:1080[0:a] [1:v]scale=1920:1080[1:a] concat=n=${paths.length}:v=1:a=1[v][a]\' -map \'[v]\' -map \'[a]\' $outputPath';



This time the logs say :




I/flutter (17343) : [AVFilterGraph @ 0xb4000074ea6265f0] No output pad can be associated to link label '1:v'.




The logs are as follows :
