  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • I have a ffmpeg command to concatenate 300+ videos of different formats. What is the proper syntax for the concat complex filter ?

    25 avril 2022, par jokoon

    I plan to concatenate a large amount of video files of different formats and resolution, some without sound, and add a short black screen "pause" of about 0.5s between each.

    


    I wrote a python script to generate such command.

    


    I created a 0.5s video file using ffmpeg.exe -t 0.5 -f lavfi -i color=c=black:s=640x480 -c:v libx264 -tune stillimage -pix_fmt yuv420p blank500ms.mp4.

    


    I then added a silent audio to it with -f lavfi -i anullsrc -c:v copy -c:a aac -shortest

    


    I now have the problem of adding a blank audio track for streams without one, but I don't want to generate new file, I want to add it to my complex filter.

    


    This is my complex script and generate command.

    


    The command (there are line returns, because I send this with the python subprocess module)

    


    ffmpeg.exe

    As you can see, some video use [11:a], because it's a silent audio stream.

    


    input10.mp4, mapped to [10] and then split (or "cloned") into blanked0 to 9, is a short pause separator.

    


    ffmpeg tells me the error

    


    [Parsed_split_55 @ 000001591c33b280] Media type mismatch between the 'Parsed_split_55' filter output pad 1 (video) and the 'Parsed_concat_56' filter input pad 5 (audio)
[AVFilterGraph @ 000001591bf1e6c0] Cannot create the link split:1 -> concat:5
Error initializing complex filters.
Invalid argument


    


    I'm a bit lost when it comes to using the [X:Y:Z] syntax, and how the order matter in the concat argument list.

    


    I'm open to any other suggestion to solve my problem. I would rather do this in a single command, without intermediate file.

    


    EDIT :

    


    For details, I already wrote a large concat+xstack filter that worked well with 8GB of memory.

    


    In this case, there are a lot of inputs, but those inputs are small, most of them are between 1 and 10MB, so it would probably not generate out-of-memory problems, although I'm not certain.

    


  • How to log unconverted files in FFMPEG due to error ?

    10 juillet 2017, par eugenemon

    I am converting 30,000 video files (each with different number of data/video/audio/subtitle streams) using a single batch file. I do not require data/subtitle streams. This is the code I am using for the batch file :

    for %%i in (*.dat *.mpg *.mpeg) do ffmpeg -hide_banner -v info -n -i %%i -map 0 -dn -sn  -c:v libx264 -crf 20  -c:a aac -b:a 192k  "%%~ni.mp4" >> log.txt 2>&1
    
pause

    The resulting log file that I get is 1.67gb in file size and is extremely difficult for me to go through to find the errors of files that weren’t converted.

    An example of a successfully converted file would look like this in the log file :

    And an example of a file that didn’t converted (in this case due to the fact that I didn’t specify to ignore subtitle stream, which I corrected by adding -sn to the batch file.) :

    Input #0, mpeg, from '571314.mpg':
    
  Duration: 00:05:44.78, start: 0.060000, bitrate: 2989 kb/s
    
    Stream #0:0[0x1bf]: Data: dvd_nav_packet
    
    Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, smpte170m, top first), 720x480 [SAR 8:9 DAR 4:3], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    
    Stream #0:2[0x81]: Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s
    
    Stream #0:3[0x20]: Subtitle: dvd_subtitle
    
    Stream #0:4[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16p, 224 kb/s
    
Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
    
Error selecting an encoder for stream 0:2

    How exactly can I output a log file that simply state the files that weren’t converted and the error that entails. Example :

    000002.mpg - Not converted
    
Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
    
Error selecting an encoder for stream 0:2
    

    
000123.mpg - Not converted
    
Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
    
Error selecting an encoder for stream 0:2

    This way, I won’t have to toy with a huge log file. Thanks !
