Using Xuggler to detect Webcam with Java
18 octobre 2012, par OneirosI'm trying to use Xuggler library to handle webcam video stream in Java.
My project contains these files :
- Xuggler Jar (xuggle-xuggler-5.4.jar)
- SLF4J Jars (required by Xuggler and downloadable here) :
- jcl-over-slf4j-1.6.4.jar
- jul-to-slf4j-1.6.4.jar
- log4j-over-slf4j-1.6.4.jar
- slf4j-api-1.6.4.jar
- slf4j-ext-1.6.4.jar
- slf4j-migrator-1.6.4.jar
- slf4j-simple-1.6.4.jar
- DisplayWebcamVideo.java as main class
I run the main method using
"vfwcap"
and"0"
as arguments.
Application starts correctly, i can see myself from the webcam but it's just the first frame : the stream freezes and i see this output :5022 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 75% full! frame dropped!
5622 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 85% full! frame dropped!
6522 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 95% full! frame dropped!
6822 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 101% full! frame dropped!
6822 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 101% full! frame dropped!
What's the problem here ? :(

FFMPEG merge two .mp4 videos - resolution distorted
9 juin 2016, par Misha MoryachokI am trying to merge two .mp4 videos, and in some cases the seconds video part is distorted in the output video. Providing an example below :
https://www.youtube.com/watch?v=wWMNTBWJ37AThe real video is : https://www.youtube.com/watch?v=ASio-j-Epi8
As you can see, we added intro before the real content, however, the real content is stretched.
In my opinion it happens because first video is 1280x720 and the second is 460x720.Providing commands for merging videos :
*1st step (convert the videos from .mp4 to .ts)
ffmpeg -i videoPathMP4 -c copy -bsf:v h264_mp4toannexb -f mpegts videoPathTS
*2nd step (merge videos)
ffmpeg -i "concat:$video1 | $video2" -c copy -bsf:a aac_adtstoasc $meagePathMP4
Video output is like you saw in provided videolink on youtube.
I also tried to change the first video resolution to be like the second video :ffmpeg -i inputVideo.mp4 -s 460x720 outputVideo.mp4
However it doesn’t helped.
Is anyone know how to solve this ?

FFMPEG realtime streaming using a remote m3u8
8 avril 2016, par JJ The SecondGood morning chaps,
I’ve been doing a long term research to do DRM solution for my client and we are almost there, here is what we’d like to achieve and please accept my lack of understanding, Im well new to FFMPEG and there are so many questions already asked but I’m not sure if they cover my questions.
Objectives :
1- To record and stream (real-time) m3u8 from a remote server : We have access to more than 3000 HLS streams (b2b project) therefore we would need to record and stream m3u8 in real-time. Currently I am able to record to mp4 or mkv but don’t understand how to stream real time
2- Stream using HL264 : We would need to make sure streams play on all devices, based on my understanding this is the correct format to use, is this correct, more than happy to hear your comments
3- Delivery to be in 3 different resolutions, HD, 488 and 380 : This is all about sizes, it is unlikely that my users would stream using mobile devices (GA says only 32000 using mobile) but still I need to make sure there are no restrictions to users
Questions :
1- I’ve seen lots of tutorials with regards to recording m3u8, converting to mp4 or .ts files, so I’m not sure how this works, do I need to export my recording to .ts files and merge them again ? If this is the case, isn’t this going to have delay in streaming ?
2- By doing this, am I using my bandwidth or source of m3u8 ?
3- If converting to .ts then would you please let me know how I can achieve this ?
Please note, my recording are (for now) all m3u8 and I need to stream as m3u8 at the same time.
I have latest version of FFMPEG installed on Ubuntu 14.4 TLS
Thank you all in advance and happy Friday !
