  • 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.

    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 ...

  • Is it still possible to compile modern x264 with the nal long start code used prior to release r1510 ?

    25 avril 2024, par Bryan Knowles

    I'm currently nerding out on old technology with HD-DVDs. The only freely available muxer is hddvdmux, I'm using MultiAVCHD for this.
Beginning with r1510, x264 switched to short start packets for NAL HRD (from what I understand). This makes the stream incompatible with hddvdmux.
deank on doom9 patched hddvdmux to accept short start codes, but in doing so, the video file plays too quickly and the audio goes out of sync.
The results I'm getting from the 2009 release of x264 leave much to be desired in comparison to modern releases, and I'd like to get those benefits while still maintaining compatibility with the original hddvdmux.
Is it possible ? If so... Any chance someone could compile a Windows binary for me with that change ? (I think it needs to be 32 bit, but not sure)

    


    I've tried multiple options with MultiAVCHD 4.1, fell back to 4.0 but am seeing weird rainbowing effects in the color from the extremely old version if x264. I admit I haven't dived in to programming, but seemed like a single change might be a reasonable request from someone already knowledgeable.

    


  • FFmpeg-Python command too long because of drawtext

    21 mai 2024, par Xascoria

    I have a FFmpeg-Python program that puts subtitles into a video, pseudocode below :

    


    for i in range(10000):
    video= video.filter(
        'drawtext', fontfile=FONT_FILE, text=cur_string, x='(w-text_w)/2', y='(h-text_h)/2',
        fontsize=FONT_SIZE, fontcolor=FONT_COLOR, borderw=2, bordercolor=FONT_OUTLINE_COLOR,
        enable=f'between(t,{i},{i+1})')

video.output(PATH).run()


    


    The code above gives the following error :

    


    FileNotFoundError: [WinError 206] The filename or extension is too long


    


    My questions are :

    


    (1) Is there anyway to check when the ffmpeg command is going to exceed the cmd length limit (8191/28878 ? not actually sure which one is in effect) in code ?

    


    (2) How do I fix this in code ?

    


  • Audio Lag Issue in Long-term FFmpeg Live Streaming with x11grab and Pulse

    8 juillet 2024, par Dhairya Verma

    I am currently working on a live streaming project where I use FFmpeg with x11grab and PulseAudio to stream headlessly from a Linux server to an RTMP endpoint. While the setup generally works well, I am encountering an issue where the audio begins to lag behind the video after approximately two days of continuous streaming.

    After two days of streaming, the audio noticeably lags behind the video. I have tried adjusting various settings and buffers, but the issue persists.

    


    Could anyone please provide any insights or suggestions on how to address this issue ?
