Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

FFMPEG - rewarp MPEGDash to MP4 changes audio bitrate mode
30 juin 2022, par Matthieu DucorpsI'm rewrapping some MPEGDash to MP4 wrapper and some files are outputed with variable audio bitrate where others with constant bitrate,and both sources looks exactly the same.


For reference :


I'm using FFMPEG 5.0 for the rewrapping

Maybe I'm missing something but,I don't see what.

ffmpeg concat doesn't sync to manual frame by frame concatenation
5 juillet 2022, par memoI have hundreds of short (10-120seconds) videos (H264 mp4) with audio (aac). (let's call these 'clips'). All identical video and audio codecs, resolution, framerate, crf, pixel format, sample rate etc.


concat_demux :


If I concat these with ffmpeg concat (demuxer), I get a single nice H264 mp4 with audio perfectly synced to the video (as expected).


cmd_args = ['ffmpeg',
 '-f concat',
 '-safe 0',
 f'-i "{output_filelist_path}"',
 '-c copy',
 '-y',
 '-r 30', # trying this out of desperation
 f'"{output_concat_demux}"'
 ]

cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)


frame_by_frame :


However, if I manually iterate every frame of every clip video and write the frames to an mp4 using skvideo.io, this video drifts out of sync with the concat_demux version.


input_dict = { '-r':str(fps) } 
output_dict = { '-r':str(fps), '-pix_fmt':'yuv420p', '-vcodec':'libx264', '-crf':'18' }
video_writer = skvideo.io.FFmpegWriter(output_path, inputdict=input_dict, outputdict=output_dict) 

for video_path in video_paths:
 video = skvideo.io.vread(video_path) # read all frames into np.array
 for frame in video:
 video_writer.writeFrame(frame)
video_writer.close()


When I compare these two files in a video editor (e.g. AfterEffects) and step through frame by frame, I can see that with every new clip, the frame_by_frame version slips 1 or 2 frames ahead of the ffmpeg concat_demux version. What is going on ? How can I fix - or at least debug - this ?


On a side note, I do need to concatenate manually frame by frame, as I'm also doing a ton of other stuff (triggering events on clip change, overlaying additional elements etc). And I need to be able to sync a concatenated audio. I was hoping to concatenate the video manually frame by frame and do my post-processing, and then mux with the audio from the ffmpeg concat_demux version. But alas they drift out of sync.



(I've found quite a few posts on SO where the problem is using ffmpeg concat results in videos which are out of sync with the audio. However, this is not my problem. My video created with ffmpeg concat is perfectly in sync with the audio, but it's out of sync with a manually frame-by-frame concatenated video.)



Update - concat_protocol


I've tried using the concat protocol. Now the output of this gives a file where the video is frame synced to the frame_by_frame version, BUT the audio is synced to the audio of the concat_demux version. So its audio is out of sync with the video.


intermediate_paths = []
for p in clip_file_list:
 intermediate_path = os.path.join(args.output_dir, 'intermediate', os.path.basename(p) + '.ts')
 intermediate_paths.append(intermediate_path)
 cmd_args = ['ffmpeg',
 f'-i "{p}"',
 '-c copy -bsf:v h264_mp4toannexb -f mpegts -y',
 f'"{intermediate_path}"'
 ]

 cmd = ' '.join(cmd_args)
 r = subprocess.call(cmd, shell=True, cwd=args.output_dir)


intermediate_paths = '|'.join(intermediate_paths)
cmd_args = ['ffmpeg',
 f'-i "concat:{intermediate_paths}"',
 '-c copy -bsf:a aac_adtstoasc',
 f'"{output_concat_path}"'
 ]

cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)


I am getting loads of errors like below


corrupt input packet in stream 0
[mp4 @ 0x137e043d0] Non-monotonous DTS in output stream 0:1; previous: 83027966, current: 83027198; changing to 83027967. This may result in incorrect timestamps in the output file.



here's the info on the two output files. Input #0 is the ffmpeg concat_demux. Input #1 is the manual frame-by-frame. Note the concat.mp4 has a framerate of 29.94 fps. I'm not sure if this is the problem. I couldn't figure out how to make this 30 (see '-r 30' in the ffmpeg concat command above)

Matomo Celebrates 15 Years of Building an Open-Source & Transparent Web Analytics Solution
<script type="text/javascript"><br />
if ('function' === typeof window.playMatomoVideo){<br />
window.playMatomoVideo("brand", "#brand")<br />
} else {<br />
document.addEventListener("DOMContentLoaded", function() { window.playMatomoVideo("brand", "#brand"); });<br />
}<br />
</script>Fifteen years ago, I realised that people (myself included) were increasingly integrating the internet into their everyday lives, and it was clear that it would only expand in the future. It was an exciting new world, but the amount of personal data shared online, level of tracking and lack of security was a growing concern. Google Analytics was just launched then and was already gaining huge traction – so data from millions of websites started flowing into Google’s database, creating what was then the biggest centralised database about people worldwide and their actions online.
So as a young engineering student, I decided we needed to build an open source and transparent solution that could help make the internet more secure and private while still providing organisations with powerful insights. I aimed to create a win-win solution for businesses and their digital consumers.
And in 2007, I started developing Matomo with the help from Scott Switzer and Jennifer Langdon (who offered me an internship and support).
All thanks to the Matomo Community
We have reached significant milestones and made major changes over the last 15 years, but we wouldn’t be where we are today without the Matomo Community.
So I would like to celebrate and thank the hundreds of volunteer developers who have donated their time to develop Matomo, the thousands of contributors who provided feedback to improve Matomo, the countless supportive forum members, our passionate team of 40 at Matomo, the numerous translators who have translated Matomo and the 1.5 million websites that choose Matomo as their analytics platform.
Team Meetup in Paris in 2012 Matomo has been a community effort built on the shoulders of many, and we will continue to work for you.
So let’s look at some milestones we have achieved over the last 15 years.
Looking back on milestones in our timeline

Our efforts continue
While we’ve seen incredible growth over the years, our work doesn’t stop there. In fact, we’re only just getting started.
Today over 55% of the internet continues to use privacy-threatening web analytics solutions, while 1.5% uses Matomo. So there are still great strides to be made to create a more private internet, and joining the Matomo Community is one way to support this movement.
There are many ways to get involved too, such as :
- Submitting feature requests
- Developing for Matomo
- Leaving Matomo a review on sites like Capterra, TrustRadius, G2 Crowd, alternativeTo, SaaSworthy, Siftery, Open Hub
- Translating Matomo
- Joining our Security Bug Bounty Programme
- Sharing Matomo with your peers
- Talking about Matomo on social platforms
So what comes next for Matomo ?
The future of Matomo is approachable, powerful and flexible. We’re strengthening the customers’ voice, expanding our resources internally (we’re continuously hiring !) and conducting rigorous customer research to craft a tool that balances usability and functionality.
I look forward to the next 15 years and seeing what the future holds for Matomo and our community.
