Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

FFmpeg 6.0 won't work because the header files can't connect or interact with each other. How do I fix the files ?
11 septembre 2023, par Señor TontoI am creating a win32 API C++ application with Microsoft Visual Studio 2022 in a .sln file. I've got quite far in basic functionalities & decided to try out video decoding & playing ; I've practiced this before but not with C++. So, I looked to see good libraries & found FFmpeg. Of course, I thought this would be quite straightforward - just import the headers & code, right ? No. Firstly, the FFmpeg I'm using is one of the pre-built binaries. The 'ffmpeg-master-latest-win64-gpl-shared.zip' From the BtbN Github repository. I decompressed it with WinRar & placed the files in Program Files (x86). Later on, I realised my mistake of placing it with 32-bit programs since it's a 64-bit build. So I transferred it to Program Files. Even after this though my issue persists. The issue being that the .h files of FFmpeg cannot communicate with each other. For some reason, they can't navigate to where the header files are. I am quite sure the reason for this may have something to do with where I save the files, the directory. Nowhere on the FFmpeg website can I see where you're expected to have the file directory at. I am sure there's a preset file path that is expected. Maybe I've named the FFmpeg folder incorrectly ? Or maybe it's not meant to go in Program Files ? The current directory for the FFmpeg folder for me is : C :\Program Files\FFmpeg. Below I will provide pictures of the errors I get where the code can't connect to other .h files as well as the file path. I'll also provide my code.

I severely doubt my code has anything to do with the issue though. It's probably directory-based. I just placed wWinmain here to keep with the character limit.

FFMPEG-PHP on Windows (not Linux as prev question) error Unknown encoder 'libfaac'
19 novembre 2020, par JonathanI am doing this on a Windows server and is not already answered as per the other question on here on a Linux server.


Im using FFMPEG on a project handling video uploads and I keep getting an issue with Videos with AAC audio encoding.


I tried using aac and other aac encoders, but the windows version of FFMPEG says unknown encoders. I tried without setting an AudioCode so it might convert to native. But still the same.


Please see the log output below :

ffmpeg drops every frame except the first
3 juin 2021, par lpaseenI'm trying to make an app that currently works fine on ubuntu 16.04 to run on ubuntu 20.04.
The setup is that :


- 

- v4l2loopback is used to create 4 new video devices - video[2345]
- it's a webcamera on /dev/video0
- this camera is split to /dev/video2,3
with








gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! tee name=rec ! queue ! v4l2sink device=/dev/video2 rec. ! queue ! v4l2sink device=/dev/video3


- 

- next it's a ffmpeg command that takes the input and streams it to a websocket




ffmpeg -video_size 640x480 -framerate 30 -f video4linux2 -i /dev/video2 -f mpegts -codec:v mpeg1video -s 640x480 -b:v 800k -bf 0 -r 30 -vf scale=640:480 http://localhost:8016/thepassword/640/480/


This works fine under ubuntu 16.04 but with 20.04 it drops every frame after the first one, and the first frame is only sent out the stream once it exits.

(I hit "q" to end it)


If I stop gst-launch and use same command to read from the real device (/dev/video0) it all works.


If I run
DISPLAY=:0 ffplay /dev/video0I get a streaming video on the screen

I tried reducing options in the ffmpeg command but even going down to what I guess is the minimum of


ffmpeg -f video4linux2 -i /dev/video2 -f mpeg1video http://localhost:8016/thepassword/640/480/


it still drops all frames.


I can get it all to work by using ffmpeg to split it instead of gst-launch so doing


ffmpeg -f video4linux2 -i /dev/video0 -codec copy -f v4l2 /dev/video3 -codec copy -f v4l2 /dev/video4


then all works except that I dunno how reliable that is on 16.04 and it requires a lot of code changes (ffmpeg output is very different from gst-launch)


I was hoping to just add a flag/plugin or something to the gst-launch/ffmpeg command to get it to work. Any chance that I can do that or is replacing gst-launch with ffmpeg the only option ?
