ffmpeg and python usage
23 février 2014, par user2063350I have an ffmpeg setup on my pc, which streams mp3 with this code :
ffmpeg -f dshow -i audio="Input device" -c:a libmp3lame -f mpegts udp://192.168.1.2:7777
Also i have a server and I want my python script to run 24/7 on server and start/stop writing stream to mp3 file every time pc get's turned on/off. I need new file every time pc turns on (use time and date for filename for example) to bypass overwriting. Using python's subprocess module and ffmpeg I can save file on my server like this :
subprocess.call('ffmpeg -y -i udp://192.168.1.2:7777 -acodec copy output.mp3')
But I need condition, when to start recording(listen if 7777 port is reciving data or something like that), is it even possible to implement such thing, using python ?
P.S. Sorry for my bad English. -
How to Convert NV12 to BGR(AVFrame to cv::Mat)
1er janvier 2019, par Steven.YeunI decoded videoframe by using FFMPEG Library from IP Camera.
This videoframe format is AV_PIX_FMT_NV12. AV_PIX_FMT_NV12 is defined on FFMPEG Library.
I want to convert NV12 to BGR (AVFrame to cv::Mat), so I try to do this
but I got wrong image :Please help me. I want to convert properly. Can anyone guess this problem ?
Please refer to following code :void CALLBACK MyCallbackFunc(AVFrame *avFrame )
{
if (avFrame != NULL)
{
cv::Mat imageRGB;
cv::Mat picI420 = cv::Mat(avFrame->height * 3 / 2, avFrame->width, CV_8UC1, avFrame->data[0]);
cv::cvtColor(picI420, imageRGB, CV_YUV2BGR_NV12);
imshow("imageRGB", imageRGB);
cvWaitKey(1);
}
}Sorry for my bad english. If you want more information please comment below.

ffmpeg acts weird at reencoding my videos
6 novembre 2022, par averagei have download multiple videos from yt-dlp (option :


yt-dlp --no-flat-playlist --audio-quality 0 --embed-thumbnail --embed-metadata --write-thumbnail --embed-subs --sub-langs all --embed-chapters --playlist-items xx playlist_url_goes_here



result in a bunch of video which encode in mkv and thumbnail in png (after preprocessing from webp/jpg)


my goal was to actually remove the embed thumbnail in mkv and replace it with png.


example of my video data when still in mkv format :

- but when i use ffmpeg to check it again result in missing metadatas in video-audio-subtitles streams
(ffmpeg also add its custom metadata in which is not good) and the output video did not have the new thumbnail i want to embed (or even old thumbnail in webp)
