Les tâches Cron régulières de la ferme
1er décembre 2010, parLa 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. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

ffmpeg-mp4box-mpeg dash plays only few segments
30 octobre 2015, par IdrisNeed help in debugging the segment dash files
The input was an MP4 with these details. This was recorded from a video camera, the output from the camera was mkv and we converted into MP4 after editing the audio via adobe
- Size : 7.51 GB Frame rate : 25 frames/ second
- Data rate : 25326kbps
- Total bitrate : 25525kbps
Converted this to another mp4 with this command
ffmpeg -i "input.mp4" -s 1280x720 -c:v libx264 -b:v 750k -bf 2 -g 75 -sc_threshold 0 -an video_1280x720_750k.mp4
ffmpeg -i "input.mp4" -c:a aac -strict experimental -b:a 96k -ar 32000 -vn audio_96k.mp4The output video has
- fps : 25
- Data rate : 761kbps
- bitrate : 761kbps
Then, created the segmented dash through MP4Box
MP4Box -dash 10000 -frag 10000 -rap -segment-name video_0_1280000\segment_ video_1280x720_750k.mp4
MP4Box -dash 3000 -frag 10000 -rap -segment-name audio_0_96000\segment_ audio_96k.mp4The MPD generated was validated online and its perfect

</mpd>Played the video through dashjs.. I believe it just plays the initial segment and errors out as MEDIA_ERR_DECODE..MEDIA_ERR_SRC_NOT_SUPPORTED.. or some message which says start not found..
Through chrome debugging I see that atleast 4 segments are correctly loading.. I am not sure whats going on..
Any help in debugging the issue is really appreciated. I really can’t understand if this is a problem with the file or ffmpeg or mp4box or chrome.

Shell out to FFMPEG from Windows Service sometimes hangs
17 avril 2013, par Jake StevensonWe have a windows service which runs on multiple machines, waiting for MSMQ messages telling it to convert various files for us. Sometimes the files are video files and we shell out an ffmpeg process to do the conversion and wait for the process to complete or error before moving on. And on some occasions, that ffmpeg process appears to "hang" and we have to RDP to the machine as an admin and manually kill it off using task manager before it can continue to accept new messages. This hung ffmpeg process will stay that way indefinitely, I've waited several days on some occasions. The services all run under a special account.
The conversion process involves multiple steps— First copying the file locally, then running ffmpeg to convert, then running mp4box for "hinting", then another ffmpeg for a thumbnail. When it hangs, it is always on the first ffmpeg portion. Killing the ffmpeg process causes that code to receive an error and allows it to handle things normally from there.
Here is the code for that first FFMPEG process. As you can see, we've tried several things to detect a hung process :
public class FFMPEGEncoder : IEncoder
{
[DllImport("kernel32.dll", SetLastError = true)]
static extern int SetErrorMode(int wMode);
private ILogger _logger = NullLogger.Instance;
public ILogger Logger
{
get { return _logger; }
set { _logger = value; }
}
private static readonly string ffmpeg = System.IO.Path.Combine(ConfigurationManager.AppSettings["FFMPEG_Dir"], "ffmpeg.exe");
private const string ffmpegArgs =
"-r 30000/1001 -b 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -flags2 -wpred-dct8x8 -level 13 -maxrate 768k -acodec libfaac -ac 2 -ar 48000 -ab 192k -s 480x320 -async 1";
public EncoderResult EncodeTheFile(string originalFile)
{
var newFileName =
VideoFileNameHelper.GetVideoFileName(originalFile);
Logger.Debug("Encoding {0} to {1} with ffmpeg", originalFile, newFileName);
RunEncoding(originalFile, newFileName);
return new EncoderResult { Filename = newFileName };
}
private void RunEncoding(string originalFile, string newFileName)
{
var process = new System.Diagnostics.Process
{
StartInfo =
{
CreateNoWindow = true,
WorkingDirectory = ConfigurationManager.AppSettings["FFMPEG_Dir"],
UseShellExecute = false,
FileName = ffmpeg,
Arguments = "-i \"" + originalFile + "\" " + ffmpegArgs + " \"" + newFileName + "\"",
RedirectStandardOutput = false,
RedirectStandardError = true
}
};
Logger.Debug("Launching ffmpeg with the following arguments:");
Logger.Debug(process.StartInfo.Arguments);
int oldMode = SetErrorMode(3);
var startTime = DateTime.Now;
process.Start();
var output = process.StandardError.ReadToEnd();
Logger.Debug("ffmpeg output:");
Logger.Debug(output);
while(!process.WaitForExit(3000))
{
if (!process.Responding)
{
process.Kill();
SetErrorMode(oldMode);
throw new Exception("Process hung");
}
if (DateTime.Now.Subtract(startTime) > new TimeSpan(0, 0, 30, 0))
{
process.Kill();
SetErrorMode(oldMode);
throw new Exception("Process hung");
}
}
SetErrorMode(oldMode);
var exitCode = process.ExitCode;
if (exitCode != 0)
{
//We got an error from ffmpeg
process.Close();
if (System.IO.File.Exists(newFileName))
{
System.IO.File.Delete(newFileName);
}
Logger.Error("Error converting video {0}", originalFile);
throw new Exception(string.Format("Unable to process the video {0}", originalFile));
}
process.Close();
}
}Despite the errormode setting code AND the code that tries to kill the process after 30 minutes, I still end up with it hung occasionally and have to manually kill the process. What am I doing wrong that would allow my system to more gracefully handle the "hung" ffmpeg processes ?
