FFMPEG stream is corrupted on Exoplayer
12 septembre 2023, par Musa KavakI'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 :




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.

Chroma key software (script)
26 janvier 2012, par Noda CajuI have thousands of small videos in HDTV quality. All with green chroma key.
I need to change green colour for a static image (company logos).There are several softwares that can change chroma key, but they are only one by one file.
This will take years to be completed.Is there a software (script) that I can make this automatic ?
