  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • How to record the bluetooth audio from my phone in my pc using ffmpeg ?

    12 septembre 2023, par Juan Inzunza

    I have my phone connected via Bluetooth to my PC and playing audio in my phone so i can hear that audio in my pc and i was trying to record that audio in my PC using ffmpeg this is the command i got so far

    


    ffmpeg -f pulse -ac 1 -ar 44100 -i alsa_input.usb-KTMicro_KT_USB_Audio_2021-06-25-0000-0000-0000--00.mono-fallback -f pulse -ac 2 -ar 44100 -i bluez_source.84_5F_04_75_B9_F6.a2dp_source -filter_complex amix=inputs=2 -i /dev/video5 -s 640x480 -vcodec libx264 -preset veryfast -crf 18 -acodec libmp3lame -ar 44100 -q:a 1 -pix_fmt yuv420p -aq 0 ~/Videos


    


    "bluez_source.84_5F_04_75_B9_F6.a2dp_source" is the name of the bluetooth audio source (my phone) but the problem is, if i am not playing audio on the device, just disappears when i execute this command "pactl list sources", and appears again when i play audio, so is listed when i run "pactl list sources" and i have to keep the phone playing audio so ffmpeg recognizes that device and not fail when executed.

    


    Finally my question is how can i keep that device in running state or suspended state without need to play audio all the time.

  • using ffmpeg libraray to write to a mp4, ffprobe shows there are 100 frames and 100 packets, but av_interleaved_write_frame only called 50 times

    here is my code to generate a mp4 file by using ffmpeg and opencv library. The opencv library is only try to generate 100 images(frames), and ffmpeg library is to compress the images to a mp4 files.

    Note that I have used the ffprobe tool(one of the tool from ffmpeg) to inspect the generated mp4 files.

    &#xA;

    I see that the mp4 file has 100 frames and 100 packets, but in my code, I have such lines :

    &#xA;

                static int call_write = 0;&#xA;&#xA;            call_write&#x2B;&#x2B;;&#xA;            printf("av_interleaved_write_frame %d\n", call_write);&#xA;

    &#xA;

    I just see that the av_interleaved_write_frame function is only called 50 times, not the expected 100 times, anyone can explain it ?

    &#xA;

    Thanks.

    &#xA;

    BTW, from the ffmpeg document( see here : For video, it should typically contain one compressed frame ), I see that a packet mainly has one video frame, so the ffprobe's result looks correct.

    &#xA;

    Here is the command I used to inspect the mp4 file :

    &#xA;

    ffprobe -show_frames output.mp4 >> frames.txt&#xA;ffprobe -show_packets output.mp4 >> packets.txt&#xA;

    &#xA;

    My testing code is derived from an answer in another question here : avformat_write_header() function call crashed when I try to save several RGB data to a output.mp4 file

  • FFMPEG Output File is Empty Nothing was Encoded (for a Picture) ?

    4 mars 2023, par Sarah Szabo

    I have a strange issue effecting one of my programs that does bulk media conversions using ffmpeg from the command line, however this effects me using it directly from the shell as well :

    &#xA;

    ffmpeg -i INPUT.mkv -ss 0:30 -y -qscale:v 2 -frames:v 1 -f image2 -huffman optimal "OUTPUT.png"&#xA;fails every run with the error message :&#xA;Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

    &#xA;

    This only happens with very specific videos, and seemingly no other videos. File type is usually .webm. These files have been downloaded properly (usually from yt-dlp), and I have tried re-downloading them just to verify their integrity.

    &#xA;

    One such file from a colleague was : https://www.dropbox.com/s/xkucr2z5ra1p2oh/Triggerheart%20Execlica%20OST%20%28Arrange%29%20-%20Crueltear%20Ending.mkv?dl=0

    &#xA;

    Is there a subtle issue with the command string ?

    &#xA;

    Notes :

    &#xA;

    removing -huffman optimal had no effect

    &#xA;

    moving -ss to before -i had no effect

    &#xA;

    removing -f image2 had no effect
