  • Is it possible to merge two or more videos in real-time like this ?

    25 février 2015, par Marko

    Is it possible to play video online that’s made of two or more video files ?

    Since my original post wasn’t clear enough, here’s expanded explanation and question.

    My site is hosted on Linux/Apache/PHP server. I have video files in FLV/F4V format. I can also convert them to other available formats if necessary. All videos have same aspect ratio and other parameters.

    What I want is to build (or use if exist) online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

    For example, visitor comes to my site and sees video titled "Welcome" available to play. When he/she clicks to play that video, I take video files "Opening.f4v", "Welcome.f4v" and "Ending.f4v" and join/merge/concatenate them one after another to create one continuous video on the fly.

    Resulting video looks like one video, with no visual clues, lags or even smallest observable delay between video parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result. This resulting video is not saved on the server, it’s just composed and played that way real-time.

    Also, if possible, user shouldn’t be made to wait for this merging to be over before he/she sees resulting video, but to be able to get first part of the video playing immediately, while merging is done simultaneously.

    Is this possible with flash/actionscript, ffmpeg, html5 or some other online technology ? I don’t need explanation how it’s possible, just a nod that it’s possible and some links to further investigate.

    Also, if one option is to use flash, what are alternatives for making this work when site is visited from iphone/ipad ?

  • Rewind problem after convert *.mp3 to *.aac

    29 août 2020, par Vitaly Vesyolko

    I need to prepare audio files in MP3 format for sending via WhatsApp to Android and iOS devices with the ability to pause and mainly rewind.

    


    To do this, I use the ffmpeg utility on my notebook with Linux Ubuntu installed. Conversion example is described in detail here FFmpeg command to convert MP3 to AAC.

    


    As a result, I get AAC audio files that cannot be rewound in the WhatsApp player. I tried to set different options that are responsible for the output sound quality, size, and so on. But the ability to rewind in the WhatsApp player disappears.

    


    Rewind - is to slide by finger the circular slider in the WhatsApp audio player widget.

    


    I also used the following online services :

    


      

    1. ONLINE-CONVERT

      2. 


    2. Convertio

      3. 


    3. ZAMZAR.

      4. 


    


    One of the first two in some cases saves files with the ability to rewind, but in most cases - without it. And it very likely depends on the original file size. This is a hypothesis - if the size is small, then it is possible to rewind the audio file in the WhatsApp player. In any case, this method is not universal.

    


    Please provide a universal solution to the task at hand - a CLI utility or a tool that would convert MP3 to AAC with the ability to rewind in the WhatsApp player. And please indicate which characteristics are responsible for the absence / presence of such functionality.

    


  • What is video timescale, timebase, or timestamp in ffmpeg ?

    28 février 2020, par Please Help

    There does not seem to be any explanation online as to what these are. People talk about them a lot. I just want to know what they are and why they are significant. Using -video_track_timescale, how would I determine a number for it ? Is it random ? Should it be 0 ?
