Use ffmpeg on OSX Xcode Project for Mac
21 décembre 2018, par cmarioI am planning to create a new app for personal use on my Mac that uses FFMPEG library, to store a feed from a RTSP IP camera.
Following this official installation procedure from FFMPEG I have manage to successfully achieve the following 2 steps:
To get ffmpeg for OS X, you first have to install Homebrew. If you don't want to use Homebrew, see the section below.
- ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then:
- brew install automake fdk-aac git lame libass libtool libvorbis libvpx \ opus sdl shtool texi2html theora wget x264 xvid yasmQuestion: My question here because I am confused, is how to import a library into Xcode so I can use it in the application I am about to build for my Mac. I can see plenty of GitHub projects related to FFMPEG with IOS/Android, but none for OSX.
All the FFMPEG commands under terminal are working fine, such as converting a video etc.

Piping images to FFmpeg stdin
21 décembre 2018, par Vincent BavaroGood morning, I need to stream trough hls many images that come in a folder as if they were video frames. I don't know prior how many they are so I believe I need to keep FFmpeg opened and passing them via stdin. I read this article already create video from growing image sequence and I changed the c# code to fit my problem like this :
using System; using System.IO; using System.Threading; using System.Threading.Tasks; using System.Diagnostics; using System.ComponentModel; namespace Example { public class Example { static void Main() { AsyncMain().GetAwaiter().GetResult(); } static async Task AsyncMain() { Console.WriteLine("Press any button to quit."); var maintask = RunFFMPEG(); var readtask = Task.Run(() => Console.Read()); await Task.WhenAny(maintask, readtask); } static async Task RunFFMPEG() { await Task.Run(() => { const int fps = 30; const string outfile = "video_seg_%05d.ts"; const string dir = @"C:\Users\funny\Desktop\in\"; const string pattern = "{0}.bmp"; const string path = dir + pattern; const string args = "-y -re -f image2pipe -framerate 2 -i - -c:v libx264 -r {0} -s 1920x1200 -b:v 256000 -flags +global_header -map 0 -f segment -segment_time 10 -segment_list_size 0 -segment_list list.m3u8 -segment_format mpegts {1}"; const int startNum = 0; const int endNum = 100; var pinf = new ProcessStartInfo("ffmpeg", string.Format(args, fps, outfile)); pinf.UseShellExecute = false; pinf.RedirectStandardInput = true; pinf.WorkingDirectory = dir; Console.WriteLine("Starting ffmpeg..."); var proc = Process.Start(pinf); using (var stream = new BinaryWriter(proc.StandardInput.BaseStream)) { for (var i = startNum; i < endNum; i++) { var file = string.Format(path, i.ToString("D4")); System.Threading.SpinWait.SpinUntil(() => File.Exists(file) && CanReadFile(file)); Console.WriteLine("Found file: " + file); stream.Write(File.ReadAllBytes(file)); } } proc.WaitForExit(); Console.WriteLine("Closed ffmpeg."); }); } static bool CanReadFile(string file) { //Needs to be able to read file FileStream fs = null; try { fs = File.OpenRead(file); return true; } catch (IOException) { return false; } finally { if (fs != null) fs.Close(); } } } }When I run the script, I get the following screen :

Anyone can tell me why isn't it processing? (I've tried to run the FFmpeg command alone on a fixed number of images without piping and it works.)

To concatenate more than two video using FFMPEG
21 décembre 2018, par Alok Kumar VermaI've been working on FFMPEG, this is indeed not an easy task since I've succeeded in doing some work. I'm done with concatenating two videos using ffmpeg but somehow when it comes to more than two it does not work. So I'm finding out some command to do my task.
The thing I did is to merge two videos are :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-strict", "experimental", "-filter_complex", "[0:v]scale=1920x1080,setsar=1:1[v0];[1:v] scale=iw*min(1920/iw\\,1080/ih):ih*min(1920/iw\\,1080/ih), pad=1920:1080:(1920-iw*min(1920/iw\\,1080/ih))/2:(1080-ih*min(1920/iw\\,1080/ih))/2,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1", "-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "1920x1080", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", savingPath};The above is working fine for two videos. I've tried altering my code for three videos but it does not work.
What I've done in the above code is :
- Added one more input after the second one
- Changed the concat=3:v=1:a=1
But it does not merge and gave me this error in my LogCat :

Will appreciate your help. Thanks.
EDITS
After following the LordNeckbeard's suggestion from the comment section, I've used his suggestion in my code but after doing that still no luck however the console's output got changed and here is the command which I used :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-i", "/mnt/m_external_sd/DCIM/Sinha's POP/20150530_073113.mp4", "-strict", "experimental", "-filter_complex", "[0:v]scale=480x640,setsar=1[v0];[1:v]scale=480x640,setsar=1[v1];[v0][0:a][v1][1:a] concat=n=3:v=1:a=1", "-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-preset", "ultrafast", savingPath};Here you can clearly see that I've used setsar=1 and used -crf only.
And the logs are :
