  • Overlay/fade image over beginning of MKV with ffmpeg

    17 mars 2021, par Spunkie

    I've got an MKV that I would like to replace the first 5 seconds with a static png image that fades in/out from black. How can I accomplish this with just ffmpeg ?

    


  • How to use rotate filter in FFmpeg ? [duplicate]

    14 décembre 2020, par shubham rawat

    I have to overlay text at each second of the video and the text should be tilt. I am able to overlay text but can't rotate the text. The command I am using to overlay is.

    


    ffmpeg -y -i gta5.mp4 -vf "[in]drawtext=text=\'"ALT"\': fontcolor=white: borderw=2: fontfile=Arial #Black:fontsize=w*0.04: x=(w-text_w)/1.5: y=120: enable=\'between(t,0,'+str(last_point)+')\',drawtext=text=\'"0"\': fontcolor=blue: borderw=2: fontfile=Arial #Black:fontsize=w*0.04: x=(w-text_w)/1.5: y=70: enable=\'between(t,0.00,10)\'[out]" -codec:a copy mos.mp4


    


    I want to use the rotate filter in this command or any filter which can tilt the text by some degrees.
I know how to rotate one text as it is already answered in Overlaying text on video with required angle using FFMPEG but I am having issues with multiple texts at different times.

    


  • FFMPEG stream is corrupted on Exoplayer

    12 septembre 2023, par Musa Kavak

    I'm trying to stream my computer's screen with UDP to display in Android with Exoplayer.

    


    I started the stream with this line :

    


    ffmpeg -re -f x11grab  -i :0 -c:v libx264 -preset ultrafast -tune zerolatency  -f mpegts udp://192.168.1.107:40001`


    


    And received with the media3 Exoplayer :

    


      Surface {
                val exoPlayer = ExoPlayer.Builder(this@MainActivity).build().apply {
                    //Same result as setMediaSource()
                    setMediaItem(MediaItem.fromUri("udp://192.168.1.107:40001"))
                    prepare()
                }

                AndroidView(
                    factory = {
                        PlayerView(it).apply {
                            player = exoPlayer
                        }
                    }
                )
  }


    


    But the result is black screen with dots :

    


    Black video with dots

    


    I can see the stream with ffplay it's working perfectly.

    


    I tried to add audio to the stream because I thought a mpegts file without audio could cause the problem. I can hear the audio but video still the same.

    


    Then switch to Windows and tried with gdigrab and... Yes, still the same.

    


    Thank you for your time in advance.
