Librairies et logiciels spécifiques aux médias
10 December 2010, byPour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

Ffmpeg - Remove rotate metadata
16 May 2014, by Ron IWhen I extract the images from a video, the resulting images are getting rotated. The orientation of the video is correct, and the images are upside down. The metadata for the original video is 180, and also for the output file, so it looks like it is copying that data and additionally rotating 180 degrees. However, since the original video is already rotated, it is flipping the video upside down.
I would like to remove the metadata for the output file containing the ’rotate’ command. I tried adding -vf rotate=0, but it didn’t work.
Here is the command I am running:
ffmpeg -i left.MOV -r 1 -f image2 left-03%d.png
I assume this is what is throwing it off (it looks like it is copying the rotate metadata from the input file and applying it to the output file):
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'left.MOV':
rotate : 180
Output #0, image2, to 'left-03%d.png':
Metadata:
rotate : 180Here’s the full output:

ffmpeg minimal requirements configuration for encoding and decoding h264 files
14 November 2013, by TheSquadI'm trying to compile ffmpeg with minimal requirements in order to encode/decode with h264.
So far my command line configuration is :
./configure --disable-yasm --disable-everything --enable-encoder=libx264 --enable-encoder=libfaac --enable-decoder=h264 --enable-muxer=h264 --enable-demuxer=h264 --enable-parser=h264 --enable-protocol=file
once compiled, I try this :
./ffmpeg -i ~/Dropbox/TestFile.mov -vcodec libx264 test.mp4
but I get an error :

test.mp4: Invalid argumentThis is probably coming from the fact that I have forgot something to enable on the ffmpeg configuration... But I can't found out what.
The test file is a video got from iPhone 4S Camera.

Download Instagram Livestreams [closed]
19 December 2020, by UnixCoonI've been looking for what Instagram livestreams can download for a long time. I can only record you via screen recording on my iPhone. But I would much rather just download it with my computer.


I've tried a lot, but I can't get the video address where a live stream is playing. I know that it is possible to download a YouTube livestream, for example, with ffmpeg.


Maybe any of you know how I download Instagram livestreams? I would be very, very happy.


I am grateful for every answer
Greetings UnixCoon
