Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -

ffmpeg - av_interleaved_write_frame() : Unknown error Error number -10053
1er février 2021, par RamUsing ffmpeg, I am able to stream video. I wrote socket Java program that connects to TCP and reading this the Live stream.



After my Java program finished recording, ffmpeg is stopping with following the error unexpectedly. I would like to keep ffmpeg running the whole time.





av_interleaved_write_frame() : Unknown error Error writing trailer of
 tcp ://XX.XX.XX.XX:5800 ?listen : Error number -10053 curred





The ffmpeg command I am using :



ffmpeg.exe -f gdigrab -an -sn -framerate 7 -i desktop -video_size 800x600 -c:v libx264 -preset ultrafast -maxrate 4000k -crf 40 -bufsize 8000k -probesize 32 -f mpegts tcp://xx.xx.xx.xx:5800?listen



Java code :



DataInputStream ois = new DataInputStream(new BufferedInputStream(socket.getInputStream()));
while((n = ois.read(buf)) != -1 && n!=3 ){
 fos.write(buf,0,n);
 fos.flush();
 cnt--;
 if(cnt ==0) break;
}

The encoding of ffmpeg does not work on iOS
25 mai 2017, par DericI would like to send encoded streaming encoded using ffmpeg.
The encoding transfer developed under the source below does not work.

Streaming audio + still image using ffmpeg
21 juin 2017, par AEnimaHI’m streaming an audio source to azure media services using RTMP and a raspberry pi. This works great using this command :
ffmpeg -f alsa -ac 1 -i hw:1,0 -c:a aac -b:a 128k -ar 44100 -f flv rtmp://...But know we want to add an image to this flv container because azure media player wants a video component.
So I added video using this command :
ffmpeg -loop 1 -i image.png -f alsa -ac 1 -i hw:1,0 -c:a aac -b:a 128k -ar 44100 -g 50 -pix_fmt yuv420p -f flv rtmp://...Yet it crashes with following log :
