  • 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.

  • FFmpeg with Nvidia GPU - full HW transcode with 50i to 50p deinterlacing

    5 janvier 2018, par Jernej Stopinšek

    I’m trying to do a full hardware transcode of an udp stream to hls
    with 50i to 50p deinterlacing.

    I’m using ffmpeg and Nvidia GPU.

    Since HLS requires deinterlacing

    https://developer.apple.com/library/content/documentation/General/Reference/HLSAuthoringSpec/Requirements.html

    I would like to deinterlace an interlaced source stream and preserve
    as much smooth motion and picture quality as possible.

    This is my command for adaptive hardware deinterlacing. It gives great results with picture, but sound is out of sync.

    If I add option "-drop_second_field 1" to h264_cuvid and remove -r:v 50 from input and put it to h264_nvenc - then transcoded stream has synced audio, but I think I’m losing quality due to drop_second_field option.

    Could someone please point me in the right direction how to properly deinterlace with cuvid and minimal possible loss of quality ?

  • why am i getting very low encoding bitrate using vaapi in ffmpeg

    19 janvier 2021, par ohroblot

    I am using this command :

    


    ffmpeg -y \
-vaapi_device /dev/dri/renderD128 \
-loop 1 -r 1 -i ./image.jpg -pix_fmt vaapi_vld \                                          
-b:v 18000k -minrate 18000k \
-vf 'format=nv12|vaapi,hwupload,scale_vaapi=w=1280:h=720' \ 
-rc_mode 3 \
-r 30 -g 60 \
-c:v h264_vaapi -f flv /dev/null


    


    I am getting very low bitrate with this, the bitrate is as low as 100Kbits/s. I get faster encoding using libx264 and my cpu. Is it an underpowered GPU ? am I missing some ffmpeg arguments ?

    


    I am not sure what's going on, could this be an issue with linux, mesa drivers, did i miss some options when I compiled ffmpeg ?

  • 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.
