ffmpeg error when try co concat videos with filter_complex
29 août 2023, par Matteo PasiniI'm trying to concatenate two videos with different resolutions. Reading around I saw that before being able to concatenate them I should scale them to the same resolution, but the command I'm using (the same one they propose on stackoverflow) doesn't seem to work. Does anyone have any ideas ?


Command :


ffmpeg -i file1.mp4 -i file2.mp4 -filter_complex "[0:v]scale=1024:576:force_original_aspect_ratio=1[v0]; [1:v]scale=1024:576:force_original_aspect_ratio=1[v1]; [v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a]" -map [v] -map [a] output.mp4

FFmpeg Drawtext - Fontconfig error : Cannot load default config file : No such file : (null)
29 mars 2023, par JamesI get the message : Fontconfig error : Cannot load default config file : No such file : (null).
No output is created.


I have installed FFmpeg full version and written this test script to add text onto an image which I drag and drop onto the BAT file.


I searched this database for solutions and found none. The script should produce an output file
test.png
, The image should have red text on it which readsHello
.

I tried to escape the path to the Font both ways without success :


`set "FONT='c\:\\windows\\fonts\\arial.ttf'" :: Font



`


.. and


`set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font`



My full script :


`set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font
set "TEXT=Hello" :: Text (no space characters allowed, see next example)
set "COLOR=red" :: Text color
set "SIZE=20" :: Font size
set "POS_X=(w-tw)/2" :: X position of text, use (w-tw)/2 for centering
set "POS_Y=(h-th)/2" :: Y position of text, use (h-th)/2 for centering


ffmpeg -i %1 -vf drawtext='fontfile=%FONT%:text=%TEXT%:fontcolor=%COLOR%:fontsize=%SIZE%:x=%POS_X%:y=%POS_Y%' - frames 1 -y test.png


pause`



The complete result :

How to config FFmpeg for xrgb and Aver Media capture card [closed]
12 mai 2023, par Plotter DesalorI'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)

"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.
