FFMPEG encode video with alpha channel to flv
29 octobre 2013, par treeI'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either
- find a codec that is supported
- find one that actually maintains the alpha
Does anyone know how to set that up ?
Thanks,
ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv
here is the report...

keepalive type and frequency in ffmpeg [on hold]
19 novembre 2013, par Jack SimthMy company has a bunch of IP cameras that we distribute - specifically Grandstream - and the manufacturer has changed their firmware. The normal keepalive that ffmpeg uses for the rtsp streams ( either ff_rtsp_send_cmd_async(s, "GET_PARAMETER", rt->control_uri, NULL) ; or ff_rtsp_send_cmd_async(s, "OPTIONS", "*", NULL) ; both in in libavformat/rtspdec.c) is no longer working, for two reasons :
1) The new Grandstream firmware is now checking for a receiver report to determine whether or not the program reading the stream is live, not just anything.
2) The new Grandstream firmware requires that the receiver report to keep the connection alive happen at least once every 25 seconds, and on the audio stream it is currently only happening about every 30 seconds or so (video is getting it every 7 seconds or so).
So after about a minute with ffmpeg connected, the camera stops sending the audio stream, the audio stream on ffmpeg reads end-of-file, and then ffmpeg shuts everything down.
As I can't change the firmware, I'm trying to dig through the ffmpeg code to make it send the appropriate receiver report for the keep alive... but I am getting nowhere. I've added a little snippet of code into the receiver reports so I know when they're running when I call ffmpeg on debug, but... well, it's not going well.
Test command :
ffmpeg -loglevel debug -i rtsp ://admin:admin@192.168.4.3:554/0 -acodec libmp3lame -ar 22050 -vcodec copy -y -f flv /dev/null &> test.txtTest output :

Recording video on Android using JavaCV
11 décembre 2013, par Fabio BergmannI'm trying to record a video in Android using the JavaCV lib.
I need to record the video in 640x360.I have installed everything as described in README.txt file and I followed the example as below :
https://code.google.com/p/javacv/source/browse/samples/RecordActivity.java
In this example, the video size is this :
private int imageWidth = 320 ;
private int imageHeight = 240 ;In my case, I need to record a video in 640x360 H.264.
But, or I get an exception or the video records with no correct image.I think that the fix is arround a correct combination on :
yuvIplimage = IplImage.create(imageWidth, imageHeight, IPL_DEPTH_8S, 2) ;
changing the depth and :
recorder.record(yuvIplimage, AV_PIX_FMT_VDPAU_H264) ;
the pixel format.Here is my code :
