  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • (Dés)Activation de fonctionnalités (plugins)

    18 février 2011, par

    Pour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
    SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
    Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".
    MediaSPIP est fourni par défaut avec l’ensemble des plugins dits "compatibles", ils ont été testés et intégrés afin de fonctionner parfaitement avec chaque (...)

  • How can I convince ffserver to save a locally-sourced webcam stream to a file in high resolution AND stream it in lower resolution ?

    2 novembre 2015, par Dominic Jacobssen

    We have a remote Linux machine, accessible over VPN, which has a USB webcam. We want to use this for video conferencing, but we also want to store the stream for archiving.

    Since the streaming bandwidth is limited, it makes sense to capture the stream on the same machine as the webcam and rsync that across after-the-fact, rather than trying to capture the streamed content, which is necessarily going to be poor quality.

    We’re trying to use ffmpeg and ffserver to achieve this, but with little success. Most of the articles on the internet either deal with just streaming a webcam, or rebroadcasting a remote stream. We found we had to recompile ffserver because of a missing "my_addr->sin_family = AF_INET ;" in the version of ffserver.c we had been using, since fixed in git.

    Here’s the ffserver.conf we’re trying to use :

    Port 43688
    
BindAddress 127.0.0.1
    
MaxHTTPConnections 2000
    
MaxClients 1000

AudioBitRate 32
    
AudioChannels 2
    
AudioSampleRate 22050
    
ACL allow localhost
    
</stream>

    When we fire this up, we get the error :

    Unable to create feed file '/tmp/feed.ffm' as it is marked readonly

    Fair enough, but this is not what is implied in the docs. Changing the directive to :

    File /tmp/feed.ffm

    allows ffserver to fire up and appear to sit and wait for ffmpeg to connect to it. However, when we fire up ffmpeg with the command :

    ffmpeg -f alsa -i pulse -r 16000 -f video4linux2 -s qvga -i /dev/video0 -r 5 -f mp4 -vcodec libx264 -sameq -acodec libfaac -ab 32k http://127.0.0.1:43688/feed.ffm

    then the webcam lights up and ffserver acknowledges the connection with the messages :

    New connection: POST /feed.ffm
    
[POST] "/feed.ffm HTTP/1.1" 200 0

    but after a few seconds we get the errors :

    [mp4 @ 0x264b160] muxer does not support non seekable output
    
Could not write header for output file #0 (incorrect codec parameters ?)

    We’ve tried various other formats (mpeg, mpegts, avi) and codecs (mpeg1video, mpeg2video, mpeg4), all without success.

    Moreover, we were under the impression that ffserver could reencode input format to a lower resolution for streaming, but if the stream resolution doesn’t match the feed resolution, we get an error about the resolutions not matching.

    Has anyone ever managed to get this working correctly ? I’ve read about vlc being able to do something like this, but the vlc command lines are well nigh impenetrable.

    Thanks !

  • ALSA buffer xrun induced by low quality source in ffmpeg capture

    24 juin 2015, par Peter Becich

    I am attempting to transfer some old Video 8 tapes to my computer, though an EasyCap USB stick and the motherboard’s sound line-in, on Ubuntu. I believe the arguments are correctly laid out below to capture from two independent streams, and encode them both into the output MP4 file.

    Edit :

    I can simplify the question a bit, now.

    ALSA buffer overrun (or underrun ?) is induced by the unreliable/noisy audio source. For instance, if ffmpeg captures the beginning of tape playback, this causes "buffer xrun" far beyond when the tape gets up to speed and playback should be normal.

    It is interesting that the bitrate shown in the ffmpeg log shoots up higher than normal when it’s producing a garbage output ! (Is this bitrate a sum of of audio and video bitrates ?)

    I’ve tried a couple of audio encoding codecs, and had the same problem.

    Using libfdk_aac :

    ffmpeg’s detection of the ALSA stream is seemingly goofed up by the inconsistencies of the tape. In the failure case, only short blips of the tapes audio exist in the output MP4. The audio bitrate of the output file is less than 10 kbps, averaged out across the whole file. The output video seems to be fine, even though the low frames-per-second in the failure case log below.

    The audio and video streams can be captured fine for short amounts of time before a source error occurs ; this provides the success case log. The failure case log was created by intentionally making an error in the source streams — turning on the camera makes a brief noisy signal.

    Is there a setting that needs to be forced to keep ffmpeg recording the audio stream, even when the tape is blank or noisy ?

    Could it be that the libfdk_aac audio encoder is tripped up by the low quality source ?

    The relevant line ; rawvideo stream is piped to this in script at bottom :

    ffmpeg -pixel_format uyvy422 -s:v 720x480 -framerate 29.97 -f rawvideo \
    
-i $PIPE  -f alsa -i hw:0,0 -vf scale=w=720:h=540 -vcodec libx264 \
    
-preset ultrafast -shortest -c:a libfdk_aac -b:a 128k -af pan=1:c0=c0  \
    
-ar 96000 $OUTFILE

    The ar argument was one attempt to force recording.

    ffmpeg log file for (short-lived) success ; high frames-per-second captured :

  • Join two ISMV files

    18 février 2015, par Violeta Grigorova

    I am currently working on a project involving some task with ismv and ismc files. First of all let me give a brief explanation for the current situation. We are using windows based products only. We are getting some ismv and ismc video files from standard CCTV server. The ouput is only ismv in beggning but after indexing we get ismc file too. For each one hour long stream we are getting one ismv file and one ismc file.

    What i need to do now is figure out a way to join multiple one hour streams. For example having a four hour long video will consist of 4 ismv video files.So far I tried ffmpeg codec, but without any success. The same goes for mp4split.

    The error for ffmpeg is the following :
    Could not find codec parameters for
    stream 0 (Video : h264 (avc1 / 0x31637661), none, 586x480, 500 kb/s) : unspecifie
    d pixel format
    Consider increasing the value for the ’analyzeduration’ and ’probesize’ options
    [concat @ 000000000436bd60]

    Executed with the following command :
    ffmpeg.exe -f concat -i F.txt -c copy output

    Here is the codec of the video taken with Media Info : http://tinypic.com/r/ff0h8z/8

    I did not manage to find a version of mp4split to use. Can you please help me solve this problem ?

    The final result should be one video only. This video should be a join between the videos given as input.
