Dear FFmpeg User Mailing List,
The versions of certain libraries are printed in the banner, such as
libavcodec.
I am curious how to find information about linked libraries, such as
libmp3lame, the LAME MP3 encoder. I would like to know:
1. Was it statically or dynamically linked?
2. If

Hi all,
I was curious about the best way to calculate the overhead of an fmp4 file vs
ADTS. The fmp4 will just contain audio.
I tried calculating the size of the ftyp, moov and subsequent moof and sidx
boxes but that seems like it’s not enough.
Is a portion of mdat overhead as well? If so,

Yes. What are you implying with your question? That the behavior is
neither a bug nor is it the way ffplay was intended to behave? (Do you
not understand
Hello Everyone,
I am using this below ffmpeg command for giving the mirror effect in the video
output file :
ffmpeg -i -pix_fmt yuv420p -vf "hflip" -metadata:s:v
rotate=180
size of video input file is 3.0 M and
size of video output file is 1.5M
Here size of video output file decreases

In this case, ffplay is the wrong tool for you, ffmpeg -i input

Please test with testsrc2 as input and no audio

Did you already try ffmpeg and one of its numerous audio
output

I have no idea about RTSP and
Hi Moritz,
I am having some issues regarding changing the fps of the streamed video.
I am applying the following ffmpeg command on the terminal which has 30 fps
in the output and pushes the stream to wowza server.
ffmpeg -re -i ~/Videos/Movie/Chhello\ Divas\ 2015.mp4 -acodec copy -r 30
-f rtsp
Hello again,
I tried to run *ffplay* without "-*nodisp*" option, where being connected
to my board via *Remote Desktop Connection*.
Unfortunately, ffplay couldn't play it.
Below is the output:
-- output of ffplay

Thank you. I fix it.
