• How do I independently fade in/out multiple (3+) overlay texts over video using FFMPEG ?

  10 janvier 2019, par Balpreet_1988

  When I use this code the 1st text fades out when second text fades in. This should not happen in this code :

  I have tried the provided code in multiple ways but this is not working.

  ffmpeg -y -i title.mp4 -filter_complex "[0:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='Top 5 Upcoming Samsung':x=50:y=200,format=yuva444p,fade=t=in:st=0.2:d=1:alpha=1[ovr1];[ovr1:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='SmartPhones in 2019':x=50:y=400,format=yuva444p,fade=t=in:st=2.2:d=1:alpha=1[ovr2];[0][ovr2]overlay" test.mp4

  This should fade in 1st text at 0.2 seconds which should stay till the end of the video and 2nd text should fade in at 2.2 seconds and remain till end of video.

• Cannot play video in TextureView Android

  26 octobre 2014, par Billda

  I have a problem with playing video on some devices. I am using textureview with mediaplayer, every methods of SurfaceTextureView are called but when I just call mediaPlayer.start(), immediately the listener with completition of playing is called. In log is this error :

  E/MediaPlayer﹕ error (1, -2147483648)

  When I list log from all applications, I can see some errors and I dont know if it is somehow related http://pastebin.com/rRxxQgdJ

  This log is from CyanogenMod with Android 4.3.1 but on some other devices like Samsung Galaxy S3 mini this error is happening.

  On my Nexus 4 everything works fine. I’ve tried convert that video with mp4 codec for android H.264 and even with ffmpeg but the result is still the same. I am using TextureVideoView implementation from here :
  https://github.com/dmytrodanylyk/video-crop/blob/master/library/src/com/dd/crop/TextureVideoView.java

  Thanks for any advice

• 3 seconds latency while streaming with Wowza Server

  18 mai 2015, par kaizen_labs

  I’m trying to develop a live streaming application with RTSP protocol.

  On the PC with the Wowza Server, I execute the following command :

  Code :

  ffmpeg -f dshow -i video="Name_Of_My_Cam":audio="Name_Of_My_Microphone" -vcodec
  
  h263p -f rtsp -muxdelay 0.1 rtsp://:1935/live/test

  And I’m trying to play this stream on a VideoView on my Samsung Galaxy Note 3 Lite. Here is the code :

  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
      VideoView vv = (VideoView) findViewById(R.id.videoView);
  
      // Receive RTSP video from Wowza Server
  
      vv.setVideoURI(Uri.parse("rtsp://:1935/live/test"));
  
      vv.requestFocus();
  
      vv.start();
  
  }

  I managed to read the video and the sound but it makes 3 secondes (or more...) to start and I keep this delay during all the streaming. It is very annoying because I want to develop a call session.

  Does anybody know how to reduce this delay ? Is it a Wowza issue ?
