  • Anomalie #2751 : conflit d’url propres

    5 juillet 2012, par Alexandre C

    Après nouveau test, oui ça marche. Au final ne rajoutait pas les suffixes id. Re-confirmer les réglages de "configuration d’url" en admin a réglé le problème. Désolé pour le bruit.

  • Encode to h265 with ffmpeg in batch

    20 septembre 2022, par Ricardo

    I have several Movies/Animes in Full HD and encoded in h264 (current market standard), and I need to perform the Encode to h265 of all these files (separated by folder and subfolders) to save space, which is the proper way to execute in batch (.bat file) ; below current code :

    


    for %%f in (*.mkv, *.mp4) do (
    ffmpeg -i "%%a" -c:a copy -c:v libx265 -vtag hvc1 lossless=1 -preset veryslow "Out\%%~na.mkv"
)


    


    In order to have the best compression of the final file and better image quality (which is visually identical to the current h264 file)

    


    Obs1 : I have both animations and movies and series with real people, can the "ffmpeg" configuration be different for each type ?

    


    Obs2 : In most files have multiple audio and video tracks and multiple subtitles, it is necessary that all audio, video and subtitles remain in the final files.

    


  • FFmpeg Image to Video command consuming 100% CPU

    23 décembre 2023, par Dishan Verma

    I am working on a project where I need to first extract all the frames of videos and after extracting the frames I need to stitch the frames back again showing 1 frame for exactly 1 seconds i.e I need to create a 1 FPS video from extracted frames.

    


    I am successfully able to extract frames of video using ffmpeg without any issues.

    


    But my FFmpeg command which I am using to convert frames to 1 FPS video is consuming 100% CPU, for example a 40 mb video input is consuming 8 GB of CPU. Below is how my FFmpeg command looks like.

    


    final String ffmpegCommandFormat = "%s -framerate 1 -i %s -c:v libx264 -pix_fmt yuv420p -crf 18 -y %s";
final String ffmpegCommand = String.format(ffmpegCommandFormat, FFMPEG_EXEC_PATH, framesPathRegex, pathToStoreProcessedVideo);


    


    I am creating a service which needs to support around 2 GB sized videos and with the current behaiviour it cannot even support 100 MB of video.

    


    Can anyone please help me here to understand why FFmpeg is consuming too high CPU and how can i resolve this issue ?
Is there any alternate/better/fast/efficient command which I can use to created 1 FPS video wither from extracted frames or directly from input video ?

    


    I am new to ffmpeg so not sure what else to explore.
