  • ffmpeg convert any user video file to run on mobiles h264 mp4

    24 octobre 2014, par tobros91

    So, i have kind of accepted this task on work but im really not sure if its possible.

    We are going to build a website where users can upload videos from their computers and mobile phone browsers. The video files can be a large range of aspect ratios, width, height, codex and file formats.

    I will have access to ffmpeg from php exec command on a web server.

    Is it possible to use this to convert the user files to one file format that works on computers, android and iphone.

    The requirements is that we can set a max width, to witch the video will be scaled, dynamically to match height.

    Does anyone know is this can be done, and be done in a reasonable amount of time. Will do project on 2 days. And if so some pointers in the right direction would be nice.

  • What's the best way to get video metadata from a MP4 file in ASP.Net MVC using C# ?

    1er janvier 2017, par Maddhacker24

    I’ve been searching on Google and StackOverflow for a good couple of hours. There seems to be a lot of similar questions on StackOverflow but they are all about 3-5 years old.

    Is using FFMPEG still the best way these days to pull metadata from a video file in a .NET web application ? And if so, what’s the best C# wrapper out there ?

    I’ve tried MediaToolkit, MediaFile.dll without any luck. I saw ffmpeg-csharpe but that looks like it hasn’t been touched in a few years.

    I haven’t found any current data on this subject. Is the ability to pull metadata from a video built into the latest version of .NET now ?

    I’m basically looking for any direction at this point.

    I should add that whatever I use could be invoked thousands of times per hour so it will need to be efficient.

  • combining MP4 video files while adding text overlay with ffmpeg

    25 septembre 2014, par valnox

    Here is a shameless request for someone to give me the required FFmpeg command. I spent way too long messing around with VLC trying to do this, and after it repeatedly messed up (mainly with video length and mp4a codecs), I started looking for other options. Now I’m coming up on a deadline and don’t have the time to go through all of the FFmpeg documentation right now.

    So, if someone is willing to help me, here is what I need :

    Take 2+ videos, combine them, add two text overlays in top left and bottom right corners (white text, black outline), and change the output bitrate (from 20k to 8k). I can easily programmatically create the list.txt of file names needed.

    Researching showed me that I likely need the "concat" and "drawtext" commands. The computer is Windows 7.

    Thanks in advance to anyone even reading this, let alone responding. Sorry to come in so ignorant, but, well... three days trying to get VLC to do it :(
