  • Cutting a video accurately at a specific time without losing quality

    6 février 2018, par mdasari

    I am using ffmpeg to cut a video accurately at a given time to another time. I know, we can simply re-encode it, but will lose the quality. Also, I do not want to use copy option because of key frames issue (i.e, the video won’t be cutt accurately). These are the commands that I used.

    ffmpeg -ss 55 -i input.mp4 -t 00:03:06 -vcodec copy -acodec copy out.mp4 
    
ffmpeg -ss 55 -i input.mp4 -t 00:03:06 out.avi

  • Softwares for adding real time text to a video [on hold]

    30 juillet 2013, par user763410

    I am trying to add real time text (like weather information, stock quotes) to a video and broadcast it. My videos are going to be 2 hours long. I have been searching for decent softwares which can do the work for me. FFmpeg can do overlays only if text to be added is available fully before running ffmpeg code, so its not real time. I have not been able to able to get gstreamer to work on my hardware.

    So, My question is :
    Please suggest some softwares which can add (text)data to a video in real time.
    Please don't post comparisons as that will trigger moderator's anger ! I don't want to start a flame war. Purpose of the question is to make a list. Btw, this should work from command line rather than a GUI.

    (Ps : If the question is closed because of being "not cnonstructive, please answer it on my google docs page here.

    Thanks very much in advance.

  • Using more than 2 NV_ENC at a time with FFMPEG

    29 décembre 2022, par lowcrawler

    I'm currently generating timelapse videos using a thread on my CPU with fluent-ffmpeg running on nodejs. It takes roughly 1 minute to generate a 10 second timelapse. I'm generating many at the same time (basically one per thread) such that I tend to get the best performance at 8 worker threads. ... overall system throughput is about one video per 12 seconds.

    


    GPU processing using h264_nvenc takes the single-thread time to about 3-4 seconds. Yippie ! I went out and bought some nVidia 1660's to take advantage.

    


    Unfortunately, when I go to generate the 3rd simultaneous video, I get "Conversion Failed !" error from FFMPEG.

    


    Some basic research seems to show you can only 2 at a time. Perhaps 3 with updated drivers.

    


    Is there a method around this ? Posts from here indicates this limit is artificial and can be worked around : https://www.techpowerup.com/268495/nvidia-silently-increases-geforce-nvenc-concurrent-sessions-limit-to-3

    


    Perhaps a way to use all the cuda/tensor/etc cores to render timelapse videos instead of just relying on the limited nv_enc ?
