  • Uploading video to Twitter sometimes doesn't work

    22 juillet 2021, par K-s S-k

    I have a very difficult situation. I've already spent 2 days and couldn't find a solution. Project on Laravel. I want to upload videos to Twitter using the Twitter API endpoints. But sometimes I am getting this error :

    


    


    file is currently unsupported

    


    


    I did everything as recommended in the official documentation Video specifications and recommendations. I get an error when I set an audio codec is aac in my video file, despite the fact that it is recommended in the official documentation, but when I set the audio codec to mp3, the video is uploaded, but the sound quality is very poor, and sometimes there is no sound at all. Please forgive me if this is awkward to read, but I want to provide all of my code. Because I don't know how to solve this anymore and I think it might help.

  • How can several .ts files be converted to one (non-fragmented) .mp4 file using ffmpeg ?

    23 juin 2021, par verified_tinker

    Problem Description

    


    The video player I'm using doesn't support .ts files, but it does play .mp4 files, so I'd like to use ffmpeg to convert my .ts files to .mp4 files.

    


    Goal Solution

    


    Use ffmpeg to download several .ts segments and transcode them into an .mp4 file that I'd load into my video player. Rinse and repeat. It'd add a delay of 10-20 seconds, but that's fine.

    


    The trick is to do the transcoding fast enough so, by the time one .mp4 file is finished playing, the next one is available ; in other words, the transcoding should take less than a second per second of footage. Ideally, it would take significantly less than that, to account for varying processing power on different devices.

    


    To clarify, when I say .mp4, I don't mean fragmented .mp4 files.

    


    


    If transcoding to some other format is faster, that might be fine, too. For example, I know the .mkv format is playable. I'm still exploring the full range of available formats.

    


    What I've Tried

    


    I tested transcoding 1 .ts file into an .mp4 file, and unfortunately it took about 6 seconds when the file was about 4 seconds long. That was with ffmpeg-wasm. I was hoping the JavaScript bridge might be slowing it down and that batching several .ts segments in 1 call might help.

    


    Command

    


    ffmpeg -i test.ts test.mp4

    (I'm running this on the browser. For the purposes of this question, consider the HTML player unavailable for use.)

    


    


    I also tested feeding the HLS live-stream URL as input to ffmpeg and outputting a single .mp4 file, but I couldn't play it until I ended the live-stream and ffmpeg finished downloading it.

    


    This one I ran on the (Windows) PC ; not the browser.

    


    Command

    


    ffmpeg -i https://stream.mux.com/lngMYGqNpHhYg2ZXqpH8WODVGzuenaZuhckdyunGpzU.m3u8 -acodec copy -bsf:a aac_adtstoasc -vcodec copy out.mp4

    30 janvier 2014, par Nitish Singla

    i want to know whats the problem behind it,i am searching from 2 days on it,but could not get the solution,i thing its problem of Execute Permission In android.Plzzz help me,,,or tell me is it possible to in android to make a video file using FFMPEG.
