Thanks for this very helpful video. You skipped the "make install" step in your video. I was wondering why I didn't get an "installed" directory. Luckily, I'm following along with the linked script. :)

Please make a video how to build ffmpeg with Newtek NDI in Windows. Even older version also ok like n5.1 Preferred 32bit

Harris Richard Anderson Laura Thompson Gary

has this error when CC=cl "../../sources/x264/config.guess: line 1: syntax error near unexpected token `newline'", noticed the link to config.guess to run with Curl is not available anymore. Is there a updated link to download and update the config.guess?

Please tell me which is better Windows ffmpeg.exe . Cross compiling from Linux or Building with Toolchain inside Windows itself ?

Thanks for sharing video❤❤❤

Thank you!!!

Hi, I would be glad if you could help me with this one: After executing line: CC=cl PKG_CONFIG_PATH=../installed/lib/pkgconfig ../../sources/ffmpeg/configure --prefix=../../installed --toolchain=msvc --arch=x86_64 --enable-yasm --enable-asm --disable-shared --enable-static --enable-libx264 --enable-gpl --enable-nonfree --enable-debug --extra-ldflags="-LIBPATH:../../installed/lib" --extra-cflags="-I../../installed/include/" I received an error: ERROR: x264 not found using pkg-config Found info somewhere to use this: pacman -S mingw-w64-x86_64-libx264 After executing above command I closed msys prompt, opened it again and execute the first line. Same error about x264 is still present.

Wow, can we also steam live camera and stream it on local network? Just like how NDI works. We have 4 cameras in a hall which goes to atem and goes to pc, if we can take the input and stream it on network so that we can send it on another hall which is 200 meter away. We will use fiber cable.

Thanks, man. I got confused by the Wikipedia article a bit, and your video cleared some stuff up. Thanks.

I want to know if can i make .so file of ffmpeg instead of executable?

Fantastic tutorial, thank you so much! From your video, I was up and running in no time, and quickly moved on to exporting single frames from a video stream, at regular intervals. Thank you!

I know this video is year old now, but heads-up that you can use the -benchmark flag on ffmpeg to time the execution, rather than trying to click on a stopwatch with perfect timing

Does this also work in WSL?

ffprobe -hide_banner -i filename.avi

I have 22 minutes and 21 second video. For every 8 seconds I need to remove next 30 seconds and then after 8 seconds again I need to remove the next 30 seconds.How to do this in ffmpeg

Nice video. This project lends itself to the use of the Python 'struct' module. with open('example.bmp', 'rb') as bmp_file: # Read the BMP header bmp_header = bmp_file.read(54) # BMP header is 54 bytes # Unpack the data from the header bmp_type = struct.unpack('<2s', bmp_header[0:2])[0] bmp_size = struct.unpack('<I', bmp_header[2:6])[0] bmp_reserved1 = struct.unpack('<H', bmp_header[6:8])[0] bmp_reserved2 = struct.unpack('<H', bmp_header[8:10])[0] bmp_offset = struct.unpack('<I', bmp_header[10:14])[0] bmp_dib_header_size = struct.unpack('<I', bmp_header[14:18])[0] bmp_width = struct.unpack('<I', bmp_header[18:22])[0] bmp_height = struct.unpack('<I', bmp_header[22:26])[0] bmp_colour_planes = struct.unpack('<H', bmp_header[26:28])[0] bmp_bits_per_pixel = struct.unpack('<H', bmp_header[28:30])[0]

Hello, thank you for your excellent video. I would like to know if I can set the time code for advace? For example, begin the timer at 09:30:40.50? Thank you

Thanks Stefan for this excellent review of the new version!

Wow great job. You should make a GIF decoder next!

Great explanation, i learnt how to add multiple fitlers, please keep up the good content.

Your notes file is missing the -f flv

i setup in ubuntu, but when in run ffmpeg command with streaming to youtube via rtmp, then i check pid using of ubuntu. it show alot of pids are using. not like in mac, it only use one pid. can you explain for it ?

how about -filter_complex_script

how to stream from webcam? or any usb cam?

can you help me with one task, I have a video, now I want to add a vertical line which moves horizontally as the audio/video plays. How can I do this?

Great tutorial Sr

I have all of those

Thanks!

why mouse is blinking

Awesome. I would really love to see a video like this which deals with more than 2 videos. And where audio also a factor. After seeing your video here, I became confident to try for myself. For which I thank you immensely. And I successfully cross fade video with audio. But when more than 2 video required to join with fade, it became so much more complex. Too much for me to figure out. Thank you once more for this.

i tried to build it with mingw-w64 gcc compiler, and the configuration worked fine. this is my config: CC=gcc ../FFmpeg-master/configure --prefix=../build --shlibdir=../build/shared --enable-gpl --enable-nonfree --enable-shared --disable-programs --target-os=mingw32 --arch=x86_64 when i did the make -j 6, it gave an error about missing or non existing file. it seems dat my make doesnt support absolute paths, and it is trying to use the current path and then using the path provided in the include of the make generated by configure, leading to missing files. i tried to replace it by the relative path and it worked, but then the FFmpeg makefile failed due to the same reason. the error is this: Makefile:1: /c/Users/username/Downloads/FFmpeg-master/Makefile: No such file or directory make: *** No rule to make target '/c/Users/username/Downloads/FFmpeg-master/Makefile'. Stop. any idea why my make is not taking the paths as absolute, and consequently messing up the compilation? NOTE: im using the mingw make, v 4.4.1

Is there a way or work around with the delay? Im trying to stream with obs to nginx rtmp hls😅

Bravissimo Stefano, l'accento italiano si sente tanto ma devo dire che sei uno dei + bravi Italiani che ho sentito in merito ad "Accento" (te lo dico da italiano all estero eh ... :)). 'Scolta ho una domanda ... ma per entrare un po + sul tecnico dove mi consigli di guardare? Intendo sulle varie opzioni di ffmpeg, mux / demux / encoding etc etc. Online non trovo tanto materiale in merito (tanta teoria, ma parzialemtne declinabile poi sui vari softwares). Ciao grande, bravo, Luca.

I’m watching this video now. Do you have a playlist for beginners? Programmers who are getting into this technology now? We don’t understand what words like: bitrate, encoding, decoding, compiling, processing, format, codec, etc mean.

Thanks , you are the best ffmpeg teacher

Hi. Thank you for this video. On Windows 11, the path to the font should be "fontfile='C\:/Windows/Fonts/Arial.ttf" if the script is executed from another drive location. Otherwise it will not find the path. I had no success with the Calibri font because my current build of ffmpeg does not support monocromatic (1bpp) fonts. For my use case I needed to add two different text boxes, so I used the -vf option (-vf "drawtext=xxx,drawtext=yyy") where xxx and yyy are variables containing the display instructions. In your demo, I think you forgot to type a ":" before the "x" axis. It will work without but I think it is better to use the attributes separator in a consistent way. Your video helped me a lot. Grazie. Giancarlo.

Hi Stef, your ffmpeg playlist is amazing . You have explain every concept of ffmpeg in deep and Simple manner which helps a lot for me. I am trying to build ffmpeg.dll , with the help of your video I am able to generate ffmpeg.exe to generate ffmpeg.dll I have given - -enable-shared in configuration but still I am getting ffmpeg.exe, for libavcodec, libavdevice getting dll but not for ffmpeg , am I missing any configuration? Can you please help me to generate ffmpeg.dll.

is there any way to eliminate the tiny audio gap between merge points? I merged 10 videos and there is a tiny skip in between merged videos

how to capture audio not from microphone but the feed that comes out to speaker, therefore audio no noise included but pure audio from desktop or browser media playing, by the way no issues with video capture, just the audio giving trouble. tak

thanks!

Hey. I’m not sure if FFMPEG is what I’m looking for, but let me tell you about what I’m looking for. I want to stream my PS3 console to my devices (iPhone, Steam Deck, etc). Is there some sort of FPGA solution for this, or is FFMPEG possibly an answer? I’m not an engineer and I’m probably in the wrong arena, but…any insight is extremely helpful.

is there another solution to this? nginx installs and runs, but i can't stream to it. OBS says the stream url is invalid. tried nmap on my server and the rtmp is open and alive

It is amazing
