  • How to config FFmpeg for xrgb and Aver Media capture card [closed]

    12 mai 2023, par Plotter Desalor

    I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

    


    My capture card is named "Live Gamer Ultra-Video"

    


    In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

    


    Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested


    


    "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

    


    But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

    How could I use rgb format with this capture card ?

    


    If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.

    


  • ffmpeg does not copy custom metadata

    20 juin 2015, par e110c0

    I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

    I tried a couple of versions, all with the same result, e.g. :

    ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

    This should work, it already gives the correct preview of metadata :

    I also tried to add the one tag I’m interested in by hand with

    -metadata:g location=+48.2683+007.7205+172.710/

    with no change in the result.

    Output as .mov doesn’t change anything, neither.

    Is there any trick to add non-standard metadata ? How do I get the location back in there ?

    Thanks in advance to anyone who can give some insight on this.

  • ffmpeg : Command Execution failed

    29 janvier 2019, par PRABHJOT SINGH

    I am using this plugin plugin link and I am uploading mp4 videos and trying to compress the video on the server using node js FFmpeg module
