  • Video/Audio file analysis - meta data, similar to MediaInfo

    23 mai 2016, par user3585420

    I usually use MediaInfo to look into my media files to see the duration of the video/audio tracks within the file. I believe MediaInfo looks at meta data of the file ( headers ) rather than the actual filestream, probably due to speed. I want a tool that actually goes through the file to work out the duration of the video/audio tracks within the media file, rather than just telling me what the headers tell me.

    The reason I need this is because I have an instance of a media file which is not reporting the correct audio track duration. Example : I have two files, an audio file and a video file, vid1.mxf and aud1.mxf, these are the same length. I ’stich’ these together using FFMPEG and because of storage failure/network issues the audio track in the resulting file is short, however it does not report as short within MediaInfo. When I listen to the file however it is clearly short, the network/storage device must have become inaccessible during the ’stitching’ toether. The audio and video input files are on different storage devices.

    I have in the past used the C# library https://github.com/naudio/NAudio which does this sort of this, however it only works with singular .wav files, and not files where there is a video inside the container too ( .mxf ).

    Thanks

  • How to stream a wmv file as an mp4 file (convert on the fly) over HTTP using ffmpeg or something similar ?

    8 juin 2016, par Adam Tal

    I understand it’s not possible to use the tag to play a WMV file.

    I thought about the following solution :

    • Streaming a video means sending small chunks of frames and sound
    • Reading a wmv file in chunks is surely possible
    • An html video tag can receive chunks in an mp4/webm/ogg format and display it

    Can I read a WMV file as a Steam and convert in on the fly to output it as if it was an MP4 file ?

    Few points :

    • The technology is not really important. I just have a problem I need to solve.. I would prefer a solution in C# or node.js because those are environments I’m comfortable with but anything else will do.
    • I will be happy to stream the file from a different server as wmv and output it as mp4 but I’m also able to download the file completely to my server and stream it from the local hard drive.
    • The mp4 output is not a must. It can also be webm or ogg (just need the video tag to support it)
