    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Getting content-length of a live-re-encoded video

    9 avril 2021, par Marius

    So, i have a lot of hevc(h265) video on a remote http server, that i want to serve as h264 through ffmpeg and nodejs. I've had a bunch of issues with content-length, or in general just getting skipping, and video duration to work properly.

    


    So the main problem is getting content-length, or any other header to make duration and skipping work properly.

    


    I've tried calculating approx content-length, but it never seems to match properly.

    


    My code so far :

    


    express setup here....
app.get('/', (req, res) => {
    res.contentType('mp4');
    
    ffmpeg(remote_video_url)
        .inputOption([
            "-hwaccel auto",
        ])
        .outputOptions(['-movflags isml+frag_keyframe'])
        .videoCodec('h264_nvenc')
        .toFormat('mp4')
        .on('error', (err,stdout,stderr) => {
            console.log('an error happened: ' + err.message);
            console.log('ffmpeg stdout: ' + stdout);
            console.log('ffmpeg stderr: ' + stderr);
        })
        .on('end', () => {
            console.log('Processing finished !');
        })
        .on('progress', (progress) => {
            console.log('Processing: ' + progress.percent + '% done');
        })
        .pipe(res, {end: true});
})


    


    Any help would be greatly appreciated

    


  • I want to modify this .bat to keep the datetime in the converted file

    14 février 2021, par Ilegator

    can anyone help me modify this .bat to keep the datetime of the file ?

    


    I've tried different options like adding -map_metadata 0 but they didn't work.

    


    This is the .bat :

    


    @echo off & setlocal enabledelayedexpansion
for %%v in ("*.mkv") do (
  set FileName=%%v

  ffmpeg -i "!FileName!" -c copy -map 0 "!FileName:~0,-4!.mp4"
)
pause


    


  • avcodec/dpx : fix check of minimal data size for unpadded content

    19 octobre 2022, par Jerome Martinez
    avcodec/dpx : fix check of minimal data size for unpadded content

    stride value is not relevant with unpadded content and the total count
    
of pixels (width x height) must be used instead of the rounding based on
    
width only then multiplied by height
    

    unpadded_10bit value computing is moved sooner in the code in order to
    
be able to use it during computing of minimal content size. Also make sure to
    
only set it for 10bit.
    

    Fix 'Overread buffer' error when the content is not lucky enough to have
    
(enough) padding bytes at the end for not being rejected by the formula
    
based on the stride value
    

    Fixes ticket #10259.
