distorted video during ffmpeg h264 video with audio recording
16 mars 2018, par DeveloperI am continuously recording a video with audio from an ip camera using ffmpeg. I am getting a distorted video when I get in to the picture. If the background is still, the video looks normal, but as soon as I step in to the picture, I see myself only being distorted while the background stays intact. If anyone went through this issue, I would really appreciate your help. Here is a command that I am using :
ffmpeg -i rtsp://admin:admin@192.168.1.9/mpeg4 -map 0 -c:v libx264 -c:a aac -pix_fmt yuv420p -f segment -segment_time 60 -segment_wrap 10 -reset_timestamps 1 %d.mp4This is a ffmpeg command output :

Add black video to video with sound
4 février 2017, par garrettlynchI’m trying to insert 13 seconds of black video at the start of a video that has sound using ffmpeg like so :
ffmpeg -f lavfi -i "color=c=black:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
"[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
[blackstart] [1:v] concat=n=2:v=1:a=0[out]" \

Flutter streaming with FFmpeg_flutter_kit not reaching server
22 juillet 2024, par Julio Cesar ReisI'm trying to stream my flutter screen to youtube using FFmpeg flutter kit. Everything seems fine but the output never reaches youtube server.


- 

-
log in using Yt flutter package.


-
create a broadcast


-
create the livestream and bind it to the broadcast


-
get the ingestion address through LiveStreamItem.cdn.ingestionInfo.ingestionAddress


-
stream the frames saved through FFmpeg :


final String rtmpUrl = "ls.cdn.ingestionInfo.ingestionAddress"

final String command = '-re -i $framePath -c:v libx264 -f flv $rtmpUrl';

await FFmpegKit.execute(command);













But at the end I get errors like SESSION_NOT_FOUND, or the stream never reaches the server which keeps my broadcast as ready and not active so I can't go live.


I've tried using the ingestionAddress plus the streamName separated by a slash, I've tried the direct stream using rtmp ://x.rtmp.youtube.com/live2/MY_API_KEY but none of that worked.
