Les tâches Cron régulières de la ferme

1er décembre 2010, par kent1

La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement.

Resize the video

8 juin 2016, par Android dev

I have a requirement for video size before upload on the server and would like to resize the video to make sure it will not go the threshold.

So far I ended up with this command :

ffmpeg -y -i E:\test3.mp4 -s 640*480 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 E:\debug_video.mp4

The issues with this command :
- is it changes aspect ratio of the video
- it works too slow (30 seconds for 12 seconds 24mb video on Nexus 5)

The best solution so far for the first issue is to check the video resolution first and only than run the ffmpeg.

Do you know how to do that with help of ffmpeg as two separate commands or as a single one ? Do you know how to make it faster ? Thank you in advance

UPDATE
The console output is below. Please let me know if you would like to get console output for onProgress callback

Why when converting avi video file to another format the first 2-3 seconds are blurry ?

13 juin 2016, par Sharon Gabriel

The source file is avi. The target new file is mp4.
The first 2-3 seconds are blurry. Then after 2-3 second the whole video until the end is smooth and sharp.

Another sub question is how come that 2.16 GB avi file after conversion using ffmpeg is only 1.34 MB ? It’s not part of a movie or something it’s collection of screenshots images i did in c# and then used AviFile Lib to create from them a avi video file. and yet from 2.16 GB to 1.34 MB and it keep the quality i think almost the same quality like the original avi file and the same duration 2:20 minutes.

About the blurry problem this is my code where i set the ffmpeg arguments and set the process :

private void Convert()

        {

            try

            {

                Control.CheckForIllegalCrossThreadCalls = false;

                if (ComboBox1.SelectedIndex == 3) 

                {

                    strFFCMD = " -i " + (char)34 + InputFile + (char)34 + " -c:v libx264 -s 1920x1080 -pix_fmt yuv420p -qp 18 -profile high444 -c:a libvo_aacenc -b:a 128k -ar 44100 -ac 2 -y " + OutputFile;

                }    

                psiProcInfo.FileName = exepath;

                psiProcInfo.Arguments = strFFCMD;        

                psiProcInfo.UseShellExecute = false;      

                psiProcInfo.WindowStyle = ProcessWindowStyle.Hidden;    

                psiProcInfo.RedirectStandardError = true;             

                psiProcInfo.RedirectStandardOutput = true;         

                psiProcInfo.CreateNoWindow = true;                 

                prcFFMPEG.StartInfo = psiProcInfo;           

                prcFFMPEG.Start();

                ffReader = prcFFMPEG.StandardError;



                do

                {

                    if (Bgw1.CancellationPending)

                    {

                        return;

                    }

                    Button5.Enabled = true;

                    Button3.Enabled = false;

                    strFFOUT = ffReader.ReadLine();                    

                    RichTextBox1.Text = strFFOUT;

                    if (strFFOUT != null)

                    {

                        if (strFFOUT.Contains("frame="))

                        {

                            currentFramestr = strFFOUT.Substring(7, 6).Trim();

                            Regex rx = new Regex(@"^\d+");

                            Match m = rx.Match(currentFramestr);

                            if (m.Success)

                            {

                                currentFrameInt = System.Convert.ToInt32(m.Value);

                            }

                        }

                    }

                    string percentage = ((double)ProgressBar1.Value / (double)ProgressBar1.Maximum * 100.0).ToString();

                    textBox3.Text = ProgressBar1.Value.ToString();                    

                    ProgressBar1.Maximum = FCount + 1;

                    ProgressBar1.Value = (currentFrameInt);

                    Label12.Text = "Current Encoded Frame: " + currentFrameInt;

                    Label11.Text = percentage;

                } while (!(prcFFMPEG.HasExited || string.IsNullOrEmpty(strFFOUT)));

            }

            catch(Exception err)

            {

                string errors = err.ToString();

            }

        }

psiProcInfo is ProcessStartInfo

prcFFMPEG is Process

And this is how it looks like when i play the target the new created converted video file the mp4 the first seconds :

Duration : 00:02:20

Width : 1920 Height : 1080

Data Rate and Total Rate both : 80kbps

Frame rate : 2 frames/second

This is the output of the ffmpeg console while converting the file.

ffmpeg conversion using libx264 looks terrible - interlaced

17 juin 2016, par justin

I’m in the process of converting some files from my set-top box (.ASF) format to something more portable that will work with plex and roku more readily. In doing so I’m using ffmpeg, but having unsatisfying results. Whereas the original doesn’t have ANY notable interlacing defects, the converted file does. I think it has something to do with the libx264 converter because of the following experiment :

Running this command :

ffmpeg -i file.asf -vcodec copy -acodec copy -bsf:a aac_adtstoasc -ss 150 -t 15 short.mp4

Which produces a file which has no interlacing artifact and appears to be same exact file size as the original (if run without the -ss and -t commands).

But running this command (without any options) :

ffmpeg -i test.asf -ss 150 -t 15 short2.mp4

Produces a file which has quite a bit of interlacing defect when playing on my HD projector thru Roku via Plex (direct play enabled, apparently no transcoding).

still frame from second transcode showing visual defect

Lest I be overly picky, I engaged my wife in this test, showing her the two files and she agreed that the one that used libx264 was significantly worse and unwatchable. Can’t figure out how to shrink this file down without causing these interlacing defects — it happens even when I don’t try to shrink it ! Any thoughts ?

Video files :

Update : Additionally, I tried a few settings to generate a MPEG4 (.AVI) file and had similar lack of success. Similar interlacing defects.

Why when converting avi video file to another format the first 2-3 seconds are blurry ?

ffmpeg conversion using libx264 looks terrible - interlaced
