• ffmpeg only drawing last text

  24 juillet 2020, par Muhammad Mohsin Ajmal

  Im using ffmpeg in flutter using the flutter ffmpeg plugin. While experimenting with it this is what I am trying to do : Show text between 1 to 2 seconds and a different text between 3 to 4 seconds in video.

  


  Only the text mentioned between 3 to 4 seconds is shown. So for me only the last drawText would work. What am I missing here ?

  


  The is the list of arguments generated

  


   Running FFmpeg with arguments: [-y, -i, /storage/emulated/0/DCIM/Camera/20200707_234610.mp4, -i, /data/user/0/com.example.example/app_flutter/watermark.png, -filter_complex, [0:v][1:v]overlay=main_w-overlay_w-5:5 ,drawtext=fontfile='/data/user/0/com.example.example/app_flutter/font.ttf':fontsize=90:x=20:y=20:text='Testing':enable='between(t\,1\,2),drawtext=fontfile='/data/user/0/com.example.example/app_flutter/font.ttf':fontsize=90:x=20:y=260:text='OTHER TEXT':enable='between(t\,3\,4)'', -crf, 27, -preset, veryfast, -c:v, libx264, -r, 30, /data/user/0/com.example.example/cache/2020-07-21T07:50:39.206386.mp4]



  


• FFmpeg - Error submitting a packet to the muxer [closed]

  26 novembre 2023, par undercash

  I m having an issue with my self compiled ffmpeg since 2020.
here is my ffmpeg comfig

  


  [```
built with gcc 11 (Ubuntu 11.4.0-1ubuntu1 22.04)
configuration : —enable-gpl —enable-version3 —enable-nonfree —enable-postproc —enable-libfdk_aac —enable-libtheora —enable-libvorbis —enable-libmp3lame —enable-libx264 —enable-libx265 —enable-libvpx —enable-librtmp —enable-libass —enable-libfreetype —enable-libdav1d —extra-libs='-lpthread -lm' —enable-openssl —enable-cuda-nvcc —enable-libnpp —extra-cflags=-I/usr/local/cuda/include —extra-ldflags=-L/usr/local/cuda/lib64 —disable-static —enable-shared

  


  
I know this is a config with nvidea but this is not relevent to the problem. Happens to me on real server without gpu , ubuntu 20 or 22.

I use ffmpeg to stream to a remote rtmp server (-f flv rtmp://xx)
Depending on the file it will consistently fail at the same time of the file with this error warning
If I just transcode a video locally, there is no issue at all
I have been testing streaming to youtube or big sites so I could discard the possibility of my own rtmp servers being misconfigured.

As a work around, and since I have not seen any threads on the internet talking about this issue, I have been using since 2020 static builds from https://johnvansickle.com/ffmpeg/
They work fine (once you enable dns resolution with them) but as I m willing to use a nvidea card I need to use my own ffmpeg with nvidea drivers.

thanks

Well pretty much what I wrote previously


  


• No sound when running ffmpeg on youtube live

  28 mai 2020, par Bartonsen

  Despite my limited knowledge in ffmpeg, I've managed to livestream my birdbox camera to youtube using ffmpeg running on a raspberry pi. The camera has also audio and by using local vlc in windows with rtsp, the audio is ok.

  



  However, on youtube there is no sound (same rtsp command as used locally in windows), and I see this "warning" in youtube studio : "The current bitrate (0) of the audio stream is lower than the recommended bitrate. We recommend using a 128 Kbps bitrate for the audio stream."

  



  How can I get the sound through youtube ?
This is the command I run. The command was found on the net, and I adopted it for my usage, and got video working straight away :
