• node js (or other) as streaming server

  20 décembre 2013, par Abdul Ali

  Apologies if a simple question but cannot find anything helpful . Am also new to the streaming concept.

  Goal is to set up a server which keeps on listening for data on a speific port. The user will be sending sequence of images from their iphone (# of images unknown).

  when the data is receieved, ffmpeg should start to get data from that port (as input) and send those images to ffserver to be streamed as a live video.

  did try Nginx-Rtmp module but the iphone developer have informed that in iphone, only ip and port can be given to open a stream (and no other part of the url can be given e.g. streamname and application name in case of nginx-rtmp)

  Any help and guide will be appreciatd that what can be used to set up a free and very simple sever that simply receives the images which ffmpeg can capture and send to ffserver .

• Ffmpeg throws File Not Found Error in Python but works fine in terminal

  6 avril 2022, par Abhishek Bhadola

  I am trying to concatenate audio and video in my pc through ffmpeg, wrote a code for that

  


  input_video=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp4")
input_audio=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp3")

print(input_video)

subprocess.run([
            "./ffmpeg",
            "-i",
            f"{input_video}",
            "-i",
            f"{input_audio}",
            "-c",
            "copy",
            "E:\\Downloaded\\2 Types of knapsack.mp4"
        ])


  


  now when i try to run the code in python it crashes and throws me an error that the file,path is wrong,but the same ffmpeg command written in terminal works fine

  


  ffmpeg -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp4" -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp3" -c "E:\Downloaded\2 Types of knapsack.mp4"


  


  any fixes.?

  


• How to make terminal refer to more recent ffmpeg installation path (currently refers to Anaconda's installation) ? [on hold]

  29 janvier 2019, par John Doe

  I would like to use ffmpeg to convert a WAV audio file to MP3, but ffmpeg doesn’t have a native MP3 encoder. Their documentation says you can use the external libmp3lame encoding library to achieve this, which "requires the presence of the libmp3lame headers and library during configuration" by "explicitly configur[ing] the build with —enable-libmp3lame."

  I tried installing the latest version of ffmpeg to my desktop and followed the configuration instructions to include libmp3lame. However, when I tried it out in my terminal, I got an error saying that ffmpeg could not find the libmp3lame encoder.

  When I enter "which ffmpeg" into my terminal, the path I am given refers to another, older installation of ffmpeg that was included automatically when I installed Anaconda years ago.

  How can I change the path of the installation my terminal refers to so that when I execute ffmpeg commands, it will use the version I more recently configured to include libmp3lame on my desktop and not the older installation included in Anaconda’s directories ?
