• ffmpeg youtube livestream stops after a while

  15 janvier 2021, par ohroblot

  I'll update this question

  


  ffmpeg -version

  


  ffmpeg -version
ffmpeg version 4.3.1-4ubuntu1 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 10 (Ubuntu 10.2.0-9ubuntu2)


  


  I run this command to use ffmpeg to stream to youtube ;

  


  ffmpeg -y -threads 12 \
-loop 1 -framerate 30 -re \
-i ./1280x720.jpg \
-i ./audio.mp3 \
-video_size 1280x720 \
-vcodec libx264 -pix_fmt yuv420p \
-b:v 4500k -maxrate 5500k -bufsize 22000k \
-preset ultrafast -crf 23 -tune stillimage \
-b:a 128k -ar 44100 -ac 2 -acodec aac \
-filter_complex "dynaudnorm=f=150:g=15" \
-r 30 -g 60 \
-f flv rtmp://a.rtmp.youtube.com/live2/xxxx 2>&1 | tee _LOG


  


  The stream is excellent for 45-53 minutes then i'll get an error like this from ffmpeg :

  


  [flv @ 0x56077027cd80] Delay between the first packet and last packet in the muxing queue is 10034000 > 10000000: forcing output


  


  then youtube starts to say, no data being received and the stream will end, which it does.

  


  This is the full log : http://0x0.st/-zUH.txt

  


• FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video

  30 décembre 2023, par user136819

  I have a WMV video file (around 60 MB size, 01:23:00 length) and I'm running a Windows Server 2016 64-bit machine for testing.
  
As far as I know, this video file was recorded using Microsoft Live Meeting 2007 back in April 2010 and there is also an associated audio file (which I'm able to play).

  


  I tried to play the video file on my machine using VLC player (latest update), however, I always see this weird MSA1 codec error :

  


  

  


  So I tried to resolve this problem by downloading and installing the Combined-Community-Codec-Pack-64bit-2015-10-18, and using its MPC-HC 64-bit player to play the video...
I still couldn't get it to play ! Here are the logs shown by the MPC player :

  Since that didn't work, I tried installing the Microsoft MPEG-4 V1/2/3 VKI Codec for ASF files and still couldn't get the players to play the video and saw the same errors as above !

  


  As a final attempt, I tried to convert this video to MP4 format using FFMPEG (version from 2020). Even this failed. Here are the logs :

  I wish to know, is there any other way I can convert this video to a more modern format so that I can play it on a modern machine and modern video player ?
  
What other codecs am I missing here ? (if so, where can I get them ?)
  
FYI, as mentioned earlier at the top, I'm only able to play the associated audio file...

  


  I'm fairly new to all this stuff, so any help is appreciated.

  


  Thanks in advance ! :)

  


• setPTS outputting wrong duration (Ffmpeg)

  16 septembre 2020, par WebDiva

  I have a video of duration 14 seconds. I applied the setPTS filter to make it 3 times slow. So the total duration should be 42s (14*3). But the output gives a 49s long video. Here is the command :

  


  ffmpeg -i video.mp4 -filter_complex "[0:v]setpts=3*PTS[v];[0:a]atempo=0.6,atempo=0.5[a]" -map "[v]" -map "[a]" output.mp4


  


  What is wrong with this command ? I tried it for different videos but all has the same weird issue. Any help will be appreciated. Regards.
