  • Queuing up videos for live stream

    5 avril 2014, par Abdul Ali

    Would first like to tell that am new to streaming and ffmpeg.

    Would try to explain scenario as much as possible.

    A web service is intended to receive chunks of video from a user. those chunks need to be simultaneously sent to the web for live streaming for a seamless viewing.

    So the videos need to be queued up for streaming to the web so that it looks like a long single video. and the strict requirement is not to make any temp file on disk.

    Did read something about pipes but am completely alien to that concept as well.

    Kindly tell how / whether this can be achieved from FFMPEG or any other free tool .

    Language used is PHP . The received videos also need to be saved to disk in parallel for new users to see from start.

  • FFmpeg - Concat Videos with different rotations

    13 janvier 2024, par diadamalol

    I want to concat two Videos that have different Rotations 90 and 270.

    



    Here is the command that I used :

    



    ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4

    



    In list.txt are the paths to both videos.

    



    What I found out is that the Output Video gets the Rotation of the Video that is listed first in list.txt. So when the Video with Rotation 90 is first, the output video gets the Rotation 90. In the Output Video the second Video will be upside down.

    



    I tried the Flag -noautorotate, but nothing changed.

    



    How do I keep the rotation of all Videos, so that the rotation of the first isnt forced onto the others ?

    


  • Is it possible to transcode various of videos to H.264 as almost the same quality using FFmpeg ?

    9 octobre 2018, par YankeeYu

    I have various of videos captured from various of resources but using different video/audio codec, bitrate and resolution.

    Here’s some example :

    • video : WMV3, bitrate : 6Mbps, audio : WMA, format : WMV
    • video : H.263, bitrate : 30Mbps, audio : MP3, format : AVI
    • video : H.264, bitrate : 20Mbps, audio : AAC, format : MKV

    Actually the video resolution may different, but this is not the key point.
    There’s quite a lot of videos make it really impossible to try the best video bitrate for each one.

    So, Is it possible to convert all these videos to H.264 and AAC with MP4 format, and keep the same video quality as the original ?

    Or the problem maybe, is there a bitrate mapping between two audio or video codec, something like (I make it up, just a example) h.263 10Mbps ≈ h.264 6Mbps ?
