icecast2, nodejs, ffmpeg, radio, ogg
25 July 2024, by UximyI have a problem which is that when I start icecast server on ubuntu and not only on ubuntu but also on windows regardless of the operating system, when I first go to the radio station in icecast2 http://localhost:8000/radio the music plays but after restarting the page in the browser, the player stops loading, I tried the solution with nocache in the browser in the address bar, nothing helps, I looked at many users configs, they did not encounter such problems, I will leave my config below, I also wrote a code on nodejs I will also leave it below, the problem plays the same that if I go to a direct icecast link, what I will do through the node js code + ffmpeg, also about the logs, nothing outputs even a hint of any error that is related to this problem

cutting with ffmpeg, video got wrong colors and pixaleted frames
21 May 2023, by Piroclasyer Pinyoafter cutting and Concatenate with ffmpeg i- example.mp4 -ss 01:02 -to 03:01 -vcodec copy -acodec copy output.mp4, it looks like the video changed resolution at some time and got wrong colors and pixaleted frames, source file was deleted, is it possible to repair it extracting the raw data?


I tried to use the -vf scale filter of ffmpeg to see if it gets other results, but stills the same.


using ffmpeg -fflags +igndts i got "Non-monotonous DTS in output stream 0:1; previous: 399777, current: 399767; changing to 399778. This may
result in incorrect timestamps in the output file."

Stop ffmpeg rtmp live stream without cutting off video
30 July 2018, by Geige VI can stream fine using the command
ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -framerate 30 -video_size 1280x720 \
-i :0.0+0,0 -c:v libx264 -preset veryfast -maxrate 1984k -bufsize 3968k \
-vf "format=yuv420p" -g 60 -c:a aac -b:a 128k -ar 44100 \
-f flv rtmp://live.twitch.tv/app/<stream key="key"></stream>Platforms generally have a delay of 10 seconds for viewers. When I terminate the ffmpeg command, the stream ends immediately for the viewers and they miss the last 10 seconds of video.
How can I terminate the stream without the end of the video cutting off abruptly?
