ffmpeg is dropping frames of second video in concat
17 June 2018, by bugwheels94I did a screen share and when sharing the screen I minimized the sharing window so the video that I am sharing has some thing weird going on. Seeking does not work on mplayer but works on VLC. However, when doing the concat
ffmpeg -i test.webm -f lavfi -i color=c=blue:s=1366x768:d=71 \
-filter_complex "[0]scale=w='min(1366\, iw)':h='min(768\, ih)':force_original_aspect_ratio=decrease,\
pad=width=1366:height=768:x=(ow-iw)/2:y=(oh-ih)/2,setsar=1/1[v1];\
[1][v1]concat=n=2[v]" -map [v] -qscale 7 result.mp4The webm video of length 155 seconds is not showing complete. Ideally the result should be 71 + 156 = 227 but I am getting 155 seconds and the webm video of concat being cropped.
If I reverse the concat order to
[v1][1]concat=n=2[v]
then everything is perfect at 227 secondsDownload test.webm
May you please tell me about what might be wrong here? Thanks

ffmpeg: Considers AVPixelFormat as Int?
16 March 2014, by jamie_yI would like to use a function
ff_load_image
.program.c
#include "../ffmpeg/libavfilter/lavfutils.h"
int main ()
{
uint8_t* data;
int linesize, width, height, log_ctx;
int i = ff_load_image(&data, &linesize, &width, &height, AV_PIX_FMT_RGB24, "blue.jpg", &log_ctx);
}This compiles, but gives a warning.
program.c: In function 'main':
program.c:11: warning: passing argument 5 of 'ff_load_image' makes pointer from integer without a cast
../ffmpeg/libavfilter/lavfutils.h:39: note: expected 'enum AVPixelFormat *' but argument is of type 'int'When I run the program, it segment faults. I can't think of any other way to specify a pixel format. Why would ffmpeg think
AV_PIX_FMT_RGB8
is an integer? It's obviously anAVPixelFormat

ffmpeg doesn't always create wave picture
17 February 2017, by Sean@LordNeckbeard and other ffmpeg experts,
can you please help me with generating wave picture. the following command works perfectly on some videos and it doesn’t on other videos:
ffmpeg -i "input.mp4" -filter_complex "[0:a]aformat = channel_layouts = mono, compand = gain = -6, showwavespic = s = 1920x384: colors =red|blue[fg]; color = s = 1920x384: color =#444444, drawgrid = width = 38:height = 38:color =#555555@0.5[bg]; [bg][fg]overlay = format = rgb, drawbox = x = (iw - w) / 2:y = (ih - h) / 2:w = iw:h = 2:color =#000000@0.4" -vframes 1 "output.png"
when working, it generates the following wave pic:
working exampleon other videos, it shows the grid but it seems that the wave signal is hidden behind the grid
Your help is greatly appreciated!
Thank you,
Sean.
