  • How to Automatically Add Silence to a Voiceover Based on Punctuation ?

    19 mai, par Big Loot

    I have a script and its voiceover. Is there a way to automatically add silence with the following durations:

    • 1 second at each comma
    • 2 seconds at each full stop
    • 3 seconds at each paragraph change

    I've tried manually inserting silence in the audio file, but it's time-consuming and prone to errors. I'm looking for a more efficient and accurate method, possibly an automated solution, that can help streamline this process.

  • How can I use ffmpeg to stream over http

    19 mai, par user3754828

    I am using the follow commands to stream to my localhost

    ffmpeg -i b.mp4 -r 60 -bufsize 1024k -vcode libtheora -qscale:v 1 -f ogg "udp://@127.0.0.1/video.ogg"

ffmpeg -i b.mp4 -r 60 -bufsize 1024k -vcode libtheora -qscale:v 1 -f ogg "http://127.0.0.1/video.ogg"

    The both work very well, at least do not show any errors, but when I try play such http stream does not, it gave me error "not found"

    Can somebody help me on it? I am complety lost in this issue...also when I try include some port, for example ffmpeg -i b.mp4 -r 60 -bufsize 1024k -vcode libtheora -qscale:v 1 -f ogg "http://127.0.0.1:8980/video.ogg" provide me input/output error...I have test the equivalent commands on vlc and is work as well.

    Thanks in advance

  • Convert m3u8 file to mp4 file in React Native Expo

    19 mai, par DRx

    How can I convert m3u8 file to mp4 file in React Native Expo? I have tried to convert m3u8 file to mp4 using FFmpegKit but I have this errors:

    'Cannot read property 'getLogLevel' of null' and 'Cannot read property 'ffmpegSession' of null'

    Also building with this package failing (Could not determine the dependencies of task ':ffmpeg-kit-react-native:compileDebugAidl'.).

    Is there a simple and easy way to convert m3u8 file in React Native Expo?

    Code I have used:

    import { FFmpegKit } from 'ffmpeg-kit-react-native';
export async function converterToMp4() {
    try {
        await FFmpegKit.executeAsync(`-i ${m3u8FileUri} ${mp4FileUri}`)

    } catch(err) {
        console.log(err)
    }
}

  • Convert CODEC of all videos in a folder from "Codec : MPEG-H Part2/HEVC (H.265) (hev1)" to "Codec : H264 - MPEG-4 AVC (part 10) (avc1)"

    19 mai, par user25123807

    I've downloaded shows and cant get them to play on TV as the codec is not supported. H264 is a compatible codec. I have noted the codec of the videos in the title of this post, and the codec which is compatible (264). I need help converting in bulk, all videos in a folder to the compatible codec - H264 - MPEG-4 AVC (part 10) (avc1).

    please help

    i have ffmpeg.

    I have tried changing the file type from mkv --> mp4 but the issue is the codec. I need help bulk converting the codec (265-->264)
