  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • FFMPEG use -strict -2

    21 août 2020, par GILO

    Hi I've been recently using the command below

    


    Ffmpeg -i song.mp3 -loop 1 -i image.jpg -filter_complex \
"[0:a]showfreqs=mode=line:ascale=log:fscale=log:s=1280x518[sf]; \
 [0:a]showwaves=s=1280x202:mode=p2p[sw]; \
 [sf][sw]vstack[fg]; \
 [1:v]scale=1280:-1,crop=iw:720[bg]; \
 [bg][fg]overlay=shortest=1:format=auto,format=yuv420p,drawtext=fontfile=/usr/share/fonts/TTF/Vera.ttf:fontcolor=white:x=10:y=10:text='\"Rated80s Prophets Prey\" by Comics On Film'[out]" \
-map "[out]" -map 0:a -c:v libx264 -preset fast -crf 18 -c:a libopus output.mp4 


    


    from this post Showfreqs and showwaves over background image ?.

    


    


    However I changed the output file to from output.mkv to output.mp4 as I would prefer to use mp4

    


    


    I get the below error

    


    [mp4 @ 0x7f962b816800] opus in MP4 support is experimental, add '-strict -2' if you want to use it.
Could not write header for output file #0 (incorrect codec parameters ?) : Experimental feature
Error initializing output stream 0:0 —
[libopus @ 0x7f962b819800] 1 frames left in the queue on closing

    


    The main information from that error is

    


    


    opus in MP4 support is experimental, add '-strict -2' if you want to use it.

    


    


    but where do I use -strict -2 within the command to make the command possible

    


  • ffmpeg - add music to an audiobook, and loop the music [closed]

    23 novembre 2024, par Rhys

    I found these example, and they all work. But I cannot overlay 2 audios and loop the shortest audio until the longest audio is finished.

    


    Audio to match Video Length

    


    ffmpeg -i VIDEO1.mp4 -stream_loop -1 -i bgmusic.mp3 -shortest -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 output.mp4


    


    Loop Audio

    


    ffmpeg -i audio.mp3 -filter_complex "aloop=loop=-1:size=10" output_loop.mp3


    


    Overlay 2 Audios

    


    ffmpeg -y -i bgmusic.mp3 -i audio.mp3 -filter_complex "[0:0]volume=1.0[a];[1:0]volume=1.0[b];[a][b]amix=inputs=2:duration=longest" -c:a libmp3lame output.mp3


    


    Here is my attempt.

    


    ffmpeg -y -i audio.mp3 -stream_loop -1 -i bgmusic.mp3 -shortest -filter_complex "[0:0]volume=1.0[a];[1:0]volume=1.0[b];[a][b]amix=inputs=2:duration=longest" -c:a libmp3lame output.mp3


    


    But this example is looping bgmusic.mp3 forever ... and audio.mp3 is stopping after the song finishes

    


    how can I get to audios to play togeather, but the shortest audio loops until the longest audio is finished ?

    


  • FFmpeg - how to set output sample_size

    23 décembre 2019, par DennisJ

    Trying to create a simple command line player for .dsf (DSD audio) files, and output to an alsa device that supports up to 24-bit 192 kHz sample rate. The following command almost works and it does play the track. Examining the bold text below, the dsf input file is converted to 24-bit/192 kHz, but the output is then truncated to 16-bit 192 kHz (pcm_s16le i.e, 16 bit little endian).

    ffmpeg -i ’01 - Sweet Georgia Brown.dsf’ -f alsa hw:0,0

    After displaying the ffmpeg banner and song metadata (tags), here is the result, bold is my emphasis :

    Duration : 00:05:14.83, start : 0.000000, bitrate : 9234 kb/s
    Stream #0:0 : Audio : flac, 192000 Hz, stereo, s32 (24 bit)
    Stream mapping :
    Stream #0:0 -> #0:0 (flac (native) -> pcm_s16le (native))
    Press [q] to stop, [?] for help
    Output #0, alsa, to ’hw:0,0’ :

    Since I can play this and many other tracks at full resolution using another player (foobar2000) it seems there might be an option in the encoder which is part of FFmpeg : Lavf57.83.100 I can find no information in any of the FFmpeg documentation that helps. Tried finding options in FFplay and even guessing using other FFmpeg options like this example.
    ffmpeg -sample_fmt s24 -i ’01 - Sweet Georgia Brown.dsf’ -f alsa hw:0,0 ***** same results.

    I’m stuck. Any suggestions ?

    Environment : Linux Mint 19.2, 64-bit, ASUS Xonar STXii sound card.
