    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Correct syntax for using ffmpeg CUDA to crop and scale videos [closed]

    9 September 2024, by Stuart

    My NVIDIA and FFMPEG configuration is as follows:

    I would like to be able to use CUDA to crop and scale videos but I cannot find the correct syntax.
My efforts usually work in terms of the scale but not the crop, here is an example of the type of problems I have been having:

    


    The source file in this example is a short mpeg2 video (960x540 with black bars top and bottom). The command is currently run from a bash script.

    


    ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -c:v mpeg2_cuvid -crop 960x408x0x66 -i $1 -vf scale_npp=1280x544 -c:a copy -c:v h264_nvenc -b:v 2M -preset slow $2


    


    This is throwing the following error:

    


    [mpeg2_cuvid @ 0x5e6d9deb56c0] cuvid decode callback error
[vist#0:0/mpeg2video @ 0x5e6d9de85b40] [dec:mpeg2_cuvid @ 0x5e6d9de7b7c0] Decoding error:        Generic error in an external library


    


    Have I a problem with my ffmpeg build, should the list of filters include something like crop_cuda or crop_npp or have I just got the wrong syntax to perform everything on the GPU (is it even possible).

    


  • How to Identify the Version of ffmpeg.dll in WebView2 Runtime Fixed Version

    19 February, by Po-Sen

    I am currently using the WebView2 runtime fixed version. After expanding the package, I found multiple DLL files, including ffmpeg.dll.

    


    In the file properties, the file version is displayed as 0.0.0.0, and the only version-related information I can see is the product version: git-2024-04-25-e3581fa2dd.

    


    enter image description here

    


    This format is different from the numeric versioning scheme I see on the official FFmpeg website: https://ffmpeg.org/download.html#releases.

    


    enter image description here

    


    I want to trace the exact FFmpeg version used in this WebView2 distribution.
Initially, I assumed e3581fa2dd was a Git commit SHA. However, after cloning the FFmpeg repository from https://git.ffmpeg.org/ffmpeg.git, I could not find this commit.

    


    Our product was recently scanned and found to contain FFmpeg version 3.4.2, which has known CVE security vulnerabilities. Therefore, we want to clarify the actual version of FFmpeg included in the WebView2 runtime.

    


    How can I determine the version of ffmpeg.dll included in WebView2 runtime fixed version?

    


  • ffmpeg remote url not working in lambda function

    9 September 2024, by Komal

    I have created lambda function to trim video.

    


    I run this command:

    


    /opt/bin/ffmpeg -protocol_whitelist file,http,https,tcp,tls -i 'https://source-bucket.s3.amazonaws.com/1.mp4' -ss 5 -t 10 -loglevel 48 -y -avoid_negative_ts 1 -acodec copy /tmp/output.mp4


    


    It gives following output:

    So, its not going beyond this: 'Opening 'https://source-bucket.s3.amazonaws.com/1.mp4'; for reading\n'

    


    And after this, it immediately gets out. Need suggestions, where its going wrong. Same command working fine on local computer.

    


    I tried cloudfront and signed url as well, as mentioned in this post: How to read remote video on Amazon S3 using ffmpeg. But it doesnt work with url. Only working when downloaded into tmp folder.

    


    Following is the final log, which you can see is no timeout. It actually finish function execution within 2-3 seconds. I have timeout set for 15 mins to the function which is maximum:
