ffmpeg - How to determine if -movflags faststart is enabled ? PHP
6 juillet 2017, par IIIOXIIIWhile I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.
After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.
To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.
This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :
exec($ffmpegPath." -help", $codecArr);
for($ii=0;$iibr>';
}Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?
Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?
TIA.

How to trim video in Android after camera capture ?
2 juillet 2017, par Sathwik GangisettyI have an app that captures images and videos. I’m able to implement cropping picture, but I cannot implement trimming video. I tried using mp4parser and ffmpeg but I cannot make it work. Can anyone suggest any tutorial to do it or please have a look at my mainActivity.java code and suggest me what to do ? I even tried K4LvideoTrimmer but couldn’t make it work as GitHub documentation is not clear.
Here is my MainActivity.java file.

ADD Image overlay to ffmpeg video stream
1er juillet 2017, par ChrisI am new to ffmpeg and want to add an HUD to the video stream, so a few questions.
- What file do I need to edit.
- What do I need to do to achieve this.
Thanks in advance. Also I am VERY new to all of this, I will need instructions step by step
I saw other questions saying to add this :
ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4But I dont know where to put it, i entered it in the terminal and got this :
pi@raspberrypi:~ $ ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4
