Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

How to mention real image instead of dummy image in ffmpeg api-example.c
2 mars 2013, par MohanI am using
video_encode_examplefunction fromapi-example.cof FFmpeg,
which basically creates 25 dummy images and encodes into a one second video.
How ever i am unable to mention real images instead of dummy ones.
If any one know how to do this for xcode objective C, pl submit a reply.

Using FFmpeg encode and UDP with a Webcam ?
14 mars, par RendresI'm trying to get frames from a Webcam using OpenCV, encode them with FFmpeg and send them using UDP.


I did before a similar project that instead of sending the packets with UDP, it saved them in a video file.


My code is.

The code compiles but it returns Segmentation fault in the function av_interleaved_write_frame(). I've tried several implementations or several codecs (in this case I'm using libopenh264, but using mpeg2video returns the same segmentation fault). I tried also with av_write_frame() but it returns the same error.


As I told before, I only want to grab frames from a webcam connected via USB, encode them to H264 and send the packets through UDP to another PC.


My console log when I run the executable is.

As you can see, FFmpeg uses libopenh264 and configures it correctly. However, no matter what. It always returns the same Segmentation fault error...


I've used commands like this.


ffmpeg -s 640x480 -f video4linux2 -i /dev/video0 -r 30 -vcodec libopenh264 -an -f h264 udp://127.0.0.1:8080


And it works perfectly, but I need to process the frames before sending them. Thats why I'm trying to use the libs.


My FFmpeg version is.

I tried to get more information of the error using gbd, but it didn't give me debugging info.


How can I solve this problem ?

Piping yt_dlp to FFMPEG using python : ffmpeg failing to recognize video data from pipe

ffmpeg_process = subprocess.Popen(

This outputs an audio file. If I look at the console I see some messages. I have removed the lengthier stuff and shown only what I find the most interesting :

It seems to me that the video data is being interpreted as bin_data and no codec is found for it. What is going on here ?


Must YT_DLP data be converted to some other format before being read by FFMPEG ?


Thank you.
