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

Thanks. Can I set an audio file metadata to another audio file ?

Hi Stef, thanks for the video. I have a very interesting project involving ffmpeg here at the company, when can we talk about it? Best Regards

Thanks will try

In a very short short period of time I learned a lot from your videos. But one thing I noticed, my CPU is overworked.

Does ffmpeg support filtering out high pitched noise?

This video is irony squared.

I cannot thank you enough. Have tried to do this at least 3 times, 12+ hours per attempt, and FINALLY thanks to you it worked! I got it cross compiling in msys2 for arch x86_64 but was never able to use the msvc toolchain! THANK YOU 🤯🤯🤯

big buck bunny - the most converted video file 😂

Thanks man.

This is pure gold, I have been wanting to code for FFMPEG but didn't know how to start. Thank you for this video!

thank you so much from making this video! I've always wanted to learn this

OMG its awesome see how video works! Keep going on!

Bonjour et merci pour ces explications. Malgré que je ne suis pas développeur, j'ai réussi à suivre les différentes étapes. À bientôt. Philippe P

👍

Thank you so much for this! Have been struggling with this for hours until I came across this video

Hello Stef, very helpful your video and the use of nginx, another interesting topic is the use of hls and dash but allocate the output hls or dash files in a server using Webdav, I've seen that this can be done with nginx or with apache, it would be great if you could do a video about it. Greetings from a fan from Mexico, keep it up with your cool content I've learned so much 👍👍👍

Great video Stef! Greetings from Sweden

Can we able to record the streamed footage in the nginx server?

Thanks, this was helpful. I suggest to make a video on how to build ffplay because that is not straightforward on Windows with MSVC.
