How to swap package configuration for environment
24 juillet 2018, par Finn MaunsellI’d like to change the location that I get ffmpeg from for my anaconda environment. The problem has occured because I want to use the ffmpeg configuration for my base system instead of the configuration meant for the environment.
If I use
ffmpegin ubuntu bash then I get this for my active environment :ffmpeg version N-91510-gd134b8d Copyright (c) 2000-2018 the FFmpeg developers
built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10) 20160609

How to reduce conversion/compression time in FFmpeg and How to merge command ?
21 novembre 2018, par Patel PinkalI want to reduce time taken to create new video after adding text in original video using FFmpeg
I had tried to search and I found this code given below for reducing time.-y -i /sdcard/videokit/in.mp4 -strict experimental -vcodec libx264 -preset ultrafast -crf 24 -acodec aac -ar 44100 -ac 2 -b 36000k -s 1280x720 -aspect 16:9 -metadata:s:v:0 rotate=0 /sdcard/videokit/out3.mp4Now, I want to add text in video and it is done in FFmpeg, by this command and its 100% working.
String[] addTextCommand = {
"-i",
"" + realFilePath,
"-vf",
"drawtext=fontsize=50:fontfile=/storage/emulated/0/Download/Cerbetica-regular.ttf:fontcolor=red:text='"
+ strText +
"':x=0:y=0: box=1: boxcolor=black@0.5:boxborderw=10: x=0: y=(h-text_h)/2",
"-strict",
"-2",
outputFilePath};Now my problem is how do I merge this two code and make one single command to make an edited video and also take less time to create a new video. In this, I have tried this command but it’s not working.
String[] addTextCommand = {
"-i",
"" + realVideoPath,
"-vf",
"-c:v", "libx264",
"-preset", "ultrafast",
"-crf", "24",
"-acodec", "aac",

"':x=0:y=0: box=1: boxcolor=black@0.5:boxborderw=10: x=0: y=(h-text_h)/2",
"-strict",
"-2",
outputFilePath};If anyone has an idea how to make command of FFmpeg please describe it and explain how to use it.
Using command of @Mulvya I got this in the console.

FFmpeg saving rtmp live stream cuts off after 3 minutes
29 octobre 2022, par user1636922I was playing with ffmpeg and was able to save a live stream to a file. The command to do so is :



ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -f h264 test.flv
</ip>


However, I have tested this twice, and both times ffmpeg stops after grabbing 3:28 worth of live video.



The entire output is here :



bash-4.2$ ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -vcodec libx264 -f h264 test.flv

Although I don't see any errors. It just looks like ffmpeg thought the stream had ended ? But that's not possible since it's a live stream.
