Video Recording on Android from Frames using javaCV
23 juin 2016, par jawad bin zafarI am using this library javaCV to record video on android. They have provided a sample VideoRecording Activity But There is some bug which I could not figure out what I am doing it wrong or what is missing which causing this bug.

The type org.bytedeco.javacpp.avutil$AVFrame cannot be resolved. It is indirectly referenced from required .class files
at following line in the above code
if (RECORD_LENGTH <= 0) try {
recorder.record(audioData);
//Log.v(LOG_TAG,"recording " + 1024*i + " to " + 1024*i+1024);
}at recorder.record(audioData). I don’t know what I am doing wrong here. New to JavaCV. Any help will be appreciated.

using libav instead of ffmpeg
21 janvier 2015, par n00bieI want to streaming video over http, i am using ogg(theora + vorbis), now i have sender and receiver, and i can run them using command line :
Sender :
ffmpeg -f video4linux2 -s 320x240 -i /dev/mycam -codec:v libtheora -qscale:v 5 -f ogg http://127.0.0.1:8080Receiver :
sudo gst-launch-0.10 tcpserversrc port = 8080 ! oggdemux ! theoradec ! autovideosinkNow, sender sends both audio and video, but receiver plays only video.
It works perfect, but now i want not to use ffmpeg and use only libav* instead.
Here’s my class for streaming :

}
BOOST_AUTO_TEST_SUITE_END() // TEST_VIDEO_WRITER
</const>But, in this case, gstreamer start playing video only when my test program stop executing (after 10 seconds in this case). It does not suit me, i want gstreamer start playing immediately after starting my test program.
Could someone help me ?
P.S. Sorry for my English.

How to make that video module can generate readable files for the module JW Player ?
4 janvier 2015, par DvexI use Drupal 7.x with Video Module, Video Pressets for FFMPEG and JW Player.
I install FFMPEG with this Guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu in Ubuntu 14.04I’m using jQuery 1.8
I downloaded the files that the JW Player module requires and renamed some files, as the guide tells me.
I set the video module so you can use FFMPEG and established the necessary pressets (FLV, MP4 and WebM) for any browser (web and mobile).
I changed the default settings of these pressets. I put check the option : Force one-pass Encoding. Because if not me error message :
PHPVideoToolkit error: Execute error. It was not possible to encode "/var/www/html/sites/default/files/private/videos/original/reel para web en loop_2.mp4" as FFmpeg returned an error. Note, however the error was encountered on the second pass of the encoding process and the first pass appear to go fine. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".

Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or heightWhen I save a node and add its corresponding video, the module generates the 3 files with their respective formats. But when thrown at the JW Player module, only plays FLV in every browser.
But not the MP4 or WebM.I checked the log and status report and all I get in order.
So I assume that the MP4 and WebM formats generated are not what the JW Player waiting.
Does anyone have the solution to this problem ? I tried to recompile FFMPEG with more codecs but it does not solve the problem.
This is my FFMPEG Configuration :
