  • What's the ideal encoding for rendering an immediate video (e.g. preview) while waiting for the high-quality video to render ? [on hold]

    20 avril 2018, par allanbreyes

    I’m working on an application that renders an MLT (OSS non-linear video-editing engine) project on a web server, which uses ffmpeg under the hood. While waiting for the high-quality render to finish (several minutes), I need to make a "best-effort" render in parallel so that users can immediately (i.e. real-time) see the results. What encoding works best for this ?

  • ffmpeg video rendering command adding empty audio to end of video

    13 janvier 2020, par Martin

    I have an ffmpeg command which is supposed to take an mp3 file and image file as inputs, and render a music video with the image as the background and the video length is the exact length of the mp3 audio file input.

    I was using this command :

    ffmpeg -loop 1 -framerate 2 -i "front.jpg" -i "audioInput.mp3" -vf "scale=2*trunc(iw/2):2*trunc(ih/2),setsar=1,format=yuv420p" -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a aac -b:a 320k -shortest -vf scale=1920:1080 -pix_fmt yuv420p "videoOutput.mp4"

    But the problem was that my audioInput.mp3 file is 1 minute 12 seconds long, and my output video was 1 minute 39 seconds, with an added couple seconds of silence at the end of the video.

    I asked a question on stackoverflow and it was closed/linked to this question. The accepted answer says that this command would not add extra seconds onto the end of the video :

    ffmpeg -y -loop 1 -framerate 2 -i "front.jpg" -i "maintheme.mp3" -c:v libx264 -tune stillimage -c:a aac -b:a 320k -pix_fmt yuv420p -shortest -fflags +shortest -max_interleave_delta 100M "result2.mp4"

    I tried using this command, and my output video was still 1.14 seconds long.
    I tried the command again with a different audio file (flac) and the video output had again 2 seconds of blank audio at the end. Is one of my flags causing extra space to be appended ? Can I cut the video’s length to be that of the audio file ?

  • Looking for video libraries for editing video on windwos/ios/azure service

    15 juillet 2015, par sanyam

    Which library would be a good bet in terms of ...
    1. Richness in features (I want to create a video from short clips and images with effects and filters). Think auto videos created from Google Photos.
    2. Extensibility - I would prefer using similar tech on IOS and Windows apps. Might have to offload some processing to a web service on Azure (windows or linux).
    3. Programmability - An API is preferred over command line as it gives more flexibility and better error handling.

    Given all these options, what is my best bet ? I’ve only looked at ffmpeg till now, is there a better alternative ?
