  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • The duration of the combined video with FFmpeg becomes 0

    24 août 2019, par sido

    I am developing an app for Android by Unity.
    When I merge video and audio with FFmpeg, the duration of the output video file is 0 though it can be played back normally.

    I tried to set duration when merging, but it didn’t work.

    The commands being executed are as follows :

    -y -i /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_video.mp4 -i /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_audio.mp3 -t 3 -c copy -map 0:v -map 1:a -shortest /storage/emulated/0/Android/data/jp.ne.company.app/files/Record/20190824122116_merged.mp4

    I expected that the duration of the merged file was the value set in MovieTime, but the duration of the actually merged file was 0.

    The log is as follows :

  • Using Unicast RTSP URIs via ffmpeg

    6 août 2019, par Chris Marshall

    I’m fairly new to ffmpeg, so I’d certainly appreciate being given an "M" to "RTFM." The ffmpeg docs are...not-so-easy...to navigate, but I’m trying.

    The goal is to develop a compiled server that incorporates ffmpeg, but first, I need to get it working via CLI.

    I have a standard AXIS Surveillance camera (AXIS M5525-E), set up as an ONVIF device (but that isn’t really relevant to this issue).

    When I query it, I get the following URI as its video streaming URI :

    rtsp://192.168.4.12/onvif-media/media.amp?profile=profile_1_jpeg&streamtype=unicast

    The IP is local to a sandboxed network.

    I add the authentication parameters to it, like so :

    rtsp://<login>:<password>@192.168.4.12/onvif-media/media.amp?profile=profile_1_jpeg&amp;streamtype=unicast
    
</password></login>

    (Yeah, I know that’s not secure, but this is just for testing and feasibility study. The whole damn sandbox is an insecure mess).

    Now, if I use VLC to open the URI, it works great (of course). Looking at it with a packet analyzer, I see the following negotiation between the device and my computer (at .2 - Clipped for brevity) :

    Id = 11
    
Source = 192.168.4.12
    
Destination = 192.168.4.2
    
Captured Length = 82
    
Packet Length = 82
    
Protocol = TCP
    
Date Received = 2019-08-06 12:18:37 +0000
    
Time Delta = 1.342024087905884
    
Information = 554 -> 53755 ([ECN, ACK, SYN], Seq=696764098, Ack=3139240483, Win=28960)
    
                    °
    
                    °
    
                    °
    
Id = 48
    
Source = 192.168.4.12
    
Destination = 192.168.4.2
    
Captured Length = 366
    
Packet Length = 366
    
Protocol = TCP
    
Date Received = 2019-08-06 12:18:38 +0000
    
Time Delta = 2.09382700920105
    
Information = 554 -> 53755 ([ACK, PUSH], Seq=696765606, Ack=3139242268, Win=1073)

    Followed immediately by UDP stream packets.

    If, however, I feed the same URI to ffmpeg :

    ffmpeg -i rtsp://<login>:<password>@192.168.4.12/onvif-media/media.amp?profile=profile_1_jpeg&amp;streamtype=unicast -c:v libx264 -crf 21 -preset veryfast -g 30 -sc_threshold 0 -f hls -hls_time 4 /Volumes/Development/webroot/fftest/stream.m3u8
    
</password></login>

    I get nothing. No negotiation at all between the device and my computer.

    After that, if I then remove the &amp;streamtype=unicast argument, I get a negotiation, and a stream :

    Id = 10
    
Source = 192.168.4.12
    
Destination = 192.168.4.2
    
Captured Length = 82
    
Packet Length = 82
    
Protocol = TCP
    
Date Received = 2019-08-06 10:37:48 +0000
    
Time Delta = 3.047425985336304
    
Information = 554 -> 49606 ([ECN, ACK, SYN], Seq=457514925, Ack=2138974173, Win=28960)
    
                    °
    
                    °
    
                    °
    
Id = 31
    
Source = 192.168.4.12
    
Destination = 192.168.4.2
    
Captured Length = 345
    
Packet Length = 345
    
Protocol = TCP
    
Date Received = 2019-08-06 10:37:49 +0000
    
Time Delta = 3.840152025222778
    
Information = 554 -> 49606 ([ACK, PUSH], Seq=457516393, Ack=2138975704, Win=1039)

    I will, of course, be continuing to work out why this is [not] happening, and will post any solutions that I find, but, like I said, I’m fairly new to this, so it’s entirely possible that I’m missing some basic stuff, and would appreciate any guidance.

    Thanks !
