• (java.net.ProtocolException) Unable to stream video in video view. (Video which was trimmed using FFmpeg

  16 décembre 2020, par Suraj

  Hello I am using the below command to trim video using FFmpeg (trim without re-encoding)

  


  String[] command = new String[]{"-y", "-i", original_path, "-ss", ""+ startMs / 1000, "-t" , "" +((endMs - startMs) / 1000), "-c", "copy", dest.getPath()};


  


  Now this trimmed video is present on my server but i am not able to stream it in video view. Whereas I can play the other videos which was not trimmed using FFmpeg.

  


  Below is the code load video in videoview

  


  VideoView videov = findViewById(R.id.videov);
Uri uri = Uri.parse("http://x.x.xxxx.xxxx:8000/xxxxxApp/media/xxxx/1608121174332.mp4");
videov.setVideoURI(uri);
videov.start();


  


  Also I can play the same video in webview control.

• ffmpeg : overlay video on top of a cropped video, map the overlay audio, cut the base video to the overlays length

  14 mars 2023, par roku

  I'm trying to overlay a video on top of a base video which is cropped to a shorts video format (standing phone). The overlayed video should be centered on top of the base layer. The base video's length should be reduced to the overlay's length. And I want to save only the overlay's audio.

  


  I've tried a bunch of stuff without much success. The current state of my ffmpeg command is this :

  


  ffmpeg -i overlay.mp4 -ss 00:00:00 -to <insert base="base"> -i base.mp4 -map 1:v:0 -map 1:a -vf "crop=ih*(9/16):ih" -crf 21 output.mp4&#xA;</insert>

  


  But this only gives me the cropped version of the base video. So my questions are :

  


  

  1. How can I figure out the base video's length ?

  


  2. How can I actually overlay (not map) other video on top of the base video ?

  


  3. How can I map the overlay's audio ? Since -map 1:a the base's audio and -map 0:a says : "Stream map '0:a' matches no streams. To ignore this, add a trailing ' ?' to the map."

  


  


  Any help is appreciated.
