  • Android : Show quick preview (live) before exporting FFmpeg Video

    1er mai 2023, par akash varlani

    Basically, I am developing a video editing app that lets the user choose some of their images and create a video slide show with music.

    



    I am using FFMPEG to generate video slide show from images but the problem is I can only show the preview of the video after executing FFMPEG command.

    



    Is googled so many blogs and all and I know there is a possible way available to display the preview of the output.

    



    Check below image from reference app. I am developing something similar to this app. There is an option to replace the image in the video. This app displays instant preview once I change the image.

    



    enter image description here

    



    Here is the link of the reference app if anyone wants to check :

    



    Clicking an EXPORT button this app lets you generate a video output. I can do that as I know FFMPEG and how to generate OUTPUT FILE using FFMPEG but what I don't know is how to display a quick preview of OUTPUT VIDEO before generating actual VIDEO FILE.

    



    On my UBUNTU device, I can view the output of FFMPEG command using FFPLAY tool but how to do the same on android device.

    



    Some useful link :

  • About Ffmpeg,Console show 'frame=0 fps=0.0 q=0.0 Lsize=0kB time=00:00:00.00' No data pull&push

    9 janvier 2019, par Lus

    I want to use Ffmpeg to pull&push video stream from HLS to RTMP.at first it’s normal,but when I open more,it’s run normally ,but no video data pull&push

    Environment：Windows64+Ngg-§rtmp-static+Ffmpeg-static+Java1.8

    It’s useless,even if I restart rtmp-server.

    ffmpeg -i xxx/live.m3u8 -vcodec h264-s 720*480 -an -f flv -y rtmp://xxx

    The first few video streams is normal,but when I open more streams (5+),
    it run normally,but no data pull.like this.

  • How can I change slice_type which is show in Elecard stream analyzer using ffmpeg ?

    10 octobre 2018, par Tooraj Jam

    I’m not ffmpeg and encodding expert and am trying to encode a MP4 file to MPEG-4 h264 .ts file.

    When Elecard stream analyzer is analyzing my result .ts file, it shows slice_type = 7 for all of i-frames as you can see in the attached screenshot.

    How can I change all these to slice_type = 2 ?

    My ffmpeg command :

    -i Source.mp4 \
    
-filter:v 'setpts=0+PTQ-STARTPTS' -metadata:s:v:0 start_time=0 \
