  • How to avoid the millisecond silence that ffmpeg adds to the beginning and end of a converted mp3 ? [on hold]

    29 décembre 2015, par Von Villamor

    I’m working on a small side project regarding splicing multiple mp3 files altogether and FFMPEG has this problem where it adds a millisecond to the beginning and the end of an audio file resulting in stops in the final mixed audio. So is there a flag or workaround available to it ?

    I’m working on hundreds and hundreds of small mp3 files so editing them one by one is next to impossible.

    Here’s a sample, the splices are at 5 seconds interval.

  • RMPT Stream Startup Dalay on FFMPEG and Gstreamer compared to OBS

    24 mars 2023, par Arruda

    I'm trying to use ffmpeg to stream a video into my RTMP server.
The problem I'm having right now is that FFMPEG seems to take a long time to start streaming the output (from what I see in my Oven Media Engine server).

    


    At the same time, when I use OBS Studio my stream starts almost immediately.
I also tried using Gstreamer, and got the same amount of delay when using FFMPEG.

    


    After a long process, I finally saw that if I added an empty audio track, then FFMPEG would start as quickly as OBS.

    


    This is my final FFMPEG command (using the empty audio track) :

    


    ffmpeg -f v4l2 -i /dev/video0 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -profile:v main -pix_fmt yuv420p -preset ultrafast -tune zerolatency -vcodec libx264 -r 10 -g 10 -keyint_min 10 -sc_threshold 0 -b:v 2000k -maxrate 2000k -bufsize 2000k -s 768x432 -acodec aac  -f flv rtmp://localhost:1935/app/mystream


    


    I'm streaming my webcam at 768x432, at 10FPS.

    


    Now, is this a bad solution in the case where there is no need for an audio in the output video ?

    


    There is no problem, nor noticible delay in the videstream if I remove the audio, the only downside is the startup time that is about 30-40 seconds.

    


    Is this delay when not using a audio track a FFMPEG issue ? or is this related to how the Oven Media Engine ingest the RTMP stream ?

    


  • Displaying javacv Frame class

    3 avril 2018, par shubham jaiswal

    I want to display a javacv Frame object directly into a gui container without converting into a buffered image or any of the jpeg/bmp as mentioned in https://docs.oracle.com/javase/8/javafx/api/javafx/scene/image/Image.html. Is there any way in which it can be achieved ?

    I want to do this as I have multiple video streams to be displayed.Currently the best performance that could be achieved is using JFrame and pixelwriter.It consumes around 8% CPU. I want to bring it to below 4% and so need a method to display the Frame object directly.

    If anyone could suggest an alternative GUI or language, it still helps.

    Regards & Thanks.
