JavaCV record video in Android
11 janvier 2017, par wyxI want to record video quiet and without preview in Android. So I choice MediaRecorder but I could record only without preview but what make me crazy is that when MediaRecorder start or stop it will with a sound dee.... I try many methods about that . But I think it perhaps sth related to the OS of the mobile. So I try JavaCV because I also want to have a Live function in my app.
But JavaCV spent me to too much time to solve some strange problems because it’s my first time to do sth about C++ src and video.

MPEG DASH - do I need to have audio and video tracks as seperate source file for creating DASH package using mp4box
10 juillet 2016, par TarunI have one source mp4, I tried to create MPEG DASH package using mp4box by GPAC.
I am able to play output MPD files in OSMO4 player by GPAC.However I am not able to play the same in DASH JS player @ http://dashif.org/reference/players/javascript/0.2.3/index.html
When I try to play the mpd in it I get error "Error creating source buffer"
I tried reading their MPD files, and I found that those guys are using audio and video as separate source track.
Ques1) Does DASH specs states that audio and video tracks should be seprate source tracks ?
Ques2) Please find below the MPD file created by me, Let me know if anybody thinks that there is a problem in it
