FFMPEG "buffer queue overflow, dropping" with trim and atrim filters

Announcing our latest open source project : DeviceDetector
This blog post is an announcement for our latest open source project release : DeviceDetector ! The Universal Device Detection library will parse any User Agent and detect the browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model.
Read on to learn more about this exciting release.
Why did we create DeviceDetector ?
Our previous library UserAgentParser only had the possibility to detect operating systems and browsers. But as more and more traffic is coming from mobile devices like smartphones and tablets it is getting more and more important to know which devices are used by the websites visitors.
To ensure that the device detection within Piwik will gain the required attention, so it will be as accurate as possible, we decided to move that part of Piwik into a separate project, that we will maintain separately. As an own project we hope the DeviceDetector will gain a better visibility as well as a better support by and for the community !
DeviceDetector is hosted on GitHub at piwik/device-detector. It is also available as composer package through Packagist.
How DeviceDetector works
Every client requesting data from a webserver identifies itself by sending a so-called User-Agent within the request to the server. Those User Agents might contain several information such as :
- client name and version (clients can be browsers or other software like feed readers, media players, apps,…)
- operating system name and version
- device identifier, which can be used to detect the brand and model.
For Example :
Mozilla/5.0 (Linux; Android 4.4.2; Nexus 5 Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.99 Mobile Safari/537.36
This User Agent contains following information :
Operating system is
Android 4.4.2
, client uses the browserChrome Mobile 32.0.1700.99
and the device is a GoogleNexus 5
smartphone.What DeviceDetector currently detects
DeviceDetector is able to detect bots, like search engines, feed fetchers, site monitors and so on, five different client types, including around 100 browsers, 15 feed readers, some media players, personal information managers (like mail clients) and mobile apps using the AFNetworking framework, around 80 operating systems and nine different device types (smartphones, tablets, feature phones, consoles, tvs, car browsers, cameras, smart displays and desktop devices) from over 180 brands.
Note : Piwik itself currently does not use the full feature set of DeviceDetector. Client detection is currently not implemented in Piwik (only detected browsers are reported, other clients are marked as Unknown). Client detection will be implemented into Piwik in the future, follow #5413 to stay updated.
Performance of DeviceDetector
Our detections are currently handled by an enormous number of regexes, that are defined in several .YML Files. As parsing these .YML files is a bit slow, DeviceDetector is able to cache the parsed .YML Files. By default DeviceDetector uses a static cache, which means that everything is cached in static variables. As that only improves speed for many detections within one process, there are also adapters to cache in files or memcache for speeding up detections across requests.
How can users help contribute to DeviceDetector ?
Submit your devices that are not detected yet
If you own a device, that is currently not correctly detected by the DeviceDetector, please create a issue on GitHub
In order to check if your device is detected correctly by the DeviceDetector go to your Piwik server, click on ‘Settings’ link, then click on ‘Device Detection’ under the Diagnostic menu. If the data does not match, please copy the displayed User Agent and use that and your device data to create a ticket.Submit a list of your User Agents
In order to create new detections or improve the existing ones, it is necessary for us to have lists of User Agents. If you have a website used by mostly non desktop devices it would be useful if you send a list of the User Agents that visited your website. To do so you need access to your access logs. The following command will extract the User Agents :
zcat ~/path/to/access/logs* | awk -F'"' '{print $6}' | sort | uniq -c | sort -rn | head -n20000 > /home/piwik/top-user-agents.txt
If you want to help us with those data, please get in touch at devicedetector@piwik.org
Submit improvements on GitHub
As DeviceDetector is free/libre library, we invite you to help us improving the detections as well as the code. Please feel free to create tickets and pull requests on Github.
What’s the next big thing for DeviceDetector ?
Please check out the list of issues in device-detector issue tracker.
We hope the community will answer our call for help. Together, we can build DeviceDetector as the most powerful device detection library !
Happy Device Detection,

AVCodecContext::time_base
in the code.UPDATE 1 :
I managed to set the correct fps by setting
time_base
property of the stream :this->stream->time_base.den = fps_num;
this->stream->time_base.num = fps_den;VLC plays the output file but it shows VLC logo instead of the video, as if there is no video stream in the file.
UPDATE 2 :
Cleaned up the code. Now if I set
codecId = AV_CODEC_ID_MPEG2VIDEO
the output file is valid and is played in both VLC and MPC-HC. Usingffprobe
on the file with FFV1 encoding yields the following result :C:\root\apps\ffmpeg>ffprobe.exe t:\test.avi
