    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.

  • FFMpeg produces low quality target file with just 1 second length on Ubuntu 20.04

    16 juillet 2021, par Matt

    I'm using FFMpeg locally on a Mac (actually using PHP-FFMpeg) and it's working perfectly. I'm running the same code on an Ubuntu server and whatever I try the output file is a tiny, low quality video with just 1 second length (the original is about 15 seconds).

    


    I installed it on the server with

    


    sudo apt update
sudo apt install ffmpeg


    


    and then restarted the server. To test now I'm running

    


    ffmpeg -i source.mp4 target.mp4


    


    from the terminal and getting this output

  • why ffmpeg only combines first 390 images when combining very large amount ( about 9k) images into video ?

    4 juillet 2021, par Siwei

    I have a VCD, and I split it into nearly 10,000 images, named like :

    


    $ ls tmp_enlarged_image_folder

vcd3_00000001.png
vcd3_00000002.png
vcd3_00000003.png
vcd3_00000004.png
...
vcd3_00089998.png
vcd3_00089999.png
vcd3_00090000.png


    


    and the following command doen't work for me :

    


    ffmpeg -loglevel trace -f image2 -r 25 -pattern_type sequence -i 'tmp_enlarged_image_folder/vcd3-%08d.png' -vcodec libx264 test.mp4



    


    and the detailed log shows as below :

  • How can several .ts files be converted to one (non-fragmented) .mp4 file using ffmpeg ?

    23 juin 2021, par verified_tinker

    Problem Description

    


    The video player I'm using doesn't support .ts files, but it does play .mp4 files, so I'd like to use ffmpeg to convert my .ts files to .mp4 files.

    


    Goal Solution

    


    Use ffmpeg to download several .ts segments and transcode them into an .mp4 file that I'd load into my video player. Rinse and repeat. It'd add a delay of 10-20 seconds, but that's fine.

    


    The trick is to do the transcoding fast enough so, by the time one .mp4 file is finished playing, the next one is available ; in other words, the transcoding should take less than a second per second of footage. Ideally, it would take significantly less than that, to account for varying processing power on different devices.

    


    To clarify, when I say .mp4, I don't mean fragmented .mp4 files.

    


    


    If transcoding to some other format is faster, that might be fine, too. For example, I know the .mkv format is playable. I'm still exploring the full range of available formats.

    


    What I've Tried

    


    I tested transcoding 1 .ts file into an .mp4 file, and unfortunately it took about 6 seconds when the file was about 4 seconds long. That was with ffmpeg-wasm. I was hoping the JavaScript bridge might be slowing it down and that batching several .ts segments in 1 call might help.

    


    Command

    


    ffmpeg -i test.ts test.mp4

    (I'm running this on the browser. For the purposes of this question, consider the HTML player unavailable for use.)

    


    


    I also tested feeding the HLS live-stream URL as input to ffmpeg and outputting a single .mp4 file, but I couldn't play it until I ended the live-stream and ffmpeg finished downloading it.

    


    This one I ran on the (Windows) PC ; not the browser.
