Anyone nterested on using FFMPEG inside own app?

[DonManfred]

Hello anyone,

i´m doing a wrapper for ffmpeg actually...

It seems to work but as i dont have worked with ffmep in the past i dont have some good commandline examples to convert a video to flv for example. Or to reduce the quality (videosize)...

So my question. Can someone provide some example commandlines to

- Convert a videofile to a much smaller one with lesser quality to reduce internet traffic when on the field...

As for now i´m trying the command

ffmpg.executecommand(Array As String("-i",File.Combine(extsdcard,"DCIM/Camera/"&flist.Get(0))))

and it results in this output so far

So. If anyone could provide other example commandlines then i will try to use these commands with my videos to see it the library is working

Comments are highly welcome

 

[DonManfred]

The video source is 29,1mb mp4
The video destination is 1,1mb flv

Seems to work

ffmpg.executecommand(Array As String("-i",File.Combine(extsdcard,"DCIM/Camera/"&flist.Get(0)),"-s","400x300","-b","512k","-async","50","-ar","11025","-ab","16k",File.Combine(File.DirRootExternal,"output_klein.flv")))

To whom who are interested:

The library is using a small .so which is the man-in-the-middle between b4a and the ffmpeg executeable which is in the Assets and are called from within the library.

I dont know if it will work on older devices. I´m using my device (a Samsung S6 EDGE) for the tests. Android Version on device is Lollipop (5.1)

Another test

        '-an -ss 0:0:2 -t 0:0:0.001 -i input.mp4 -f image2 -s 110x90 thumb%d.jpg
        ffmpg.executecommand(Array As String("-an","-ss","0:0:2","-t","0:0:0.001","-i",File.Combine(extsdcard,"DCIM/Camera/"&flist.Get(0)),"-f","image2","-s","110x90",File.Combine(File.DirRootExternal,"thumb%d.jpg")))

This should create a thumbnail image...

works

Very nice Don....now I don't need to do it Thank you.

It is good that you are using a small so-library. The so-library can be compiled according to which codecs, containers, protocol which you would like to support but the more you support, the bigger the so-files will become. See my FFmpeg_b4a wrapper I wrote some time ago for further information. Anyway, it would be nice when you have finished it if you could give a link later to the build and configuration process you used for compiling the so-library in case someone would like to enhance it or build one for different platforms (Arm, X86 etc).

I look forward to testing it.

 

[DonManfred]

It is good that you are using a small so-library.

No, i´m NOT doing a .so... The .so is available. The wrapper for b4a is 30kb jar and a few bytes of xml.
PLUS a 15mb ffmpeg executable inside the assets folder.

When i´m in the stage of beta testing i´ll send you a copy of it... For now it is nothing more than doing the wrappe and doing first steps in using it.

I used ffmpeg to convert and stream video on my VPS, I think I can give you some commands. I'm using mobile so I will send you when I get my computer.

 

[susu]

Here some commands I used on CentOS, not sure it can be used in Android?

1. Save a stream into a file:

ffmpeg -i http://www.example.com/playlist.m3u8 -vcodec copy -c:a aac -strict -2 -ar 44100 -ab 48k video.mp4

2. Save a stream into a file with subtitile:

ffmpeg -i http://www.example.com/playlist.m3u8 -vcodec libx264 -c:a aac -strict -2 -ar 44100 -ab 48k -vf subtitles=subtitle.srt video.mp4

3. Add watermark into video:

ffmpeg -i source.mp4 -vf "movie=/folder/logo.png [watermark]; [in][watermark] overlay=0:0 [out]" -vcodec libx264 -acodec copy -f mp4 video.mp4

4. Convert mp4 to webm format:

ffmpeg -i source.mp4 -c:v libvpx -crf 10 -b:v 1M -c:a libvorbis video.webm

5. Convert mp4 to gif (from 00:00:02 and 5 seconds long):

ffmpeg -t 5 -ss 00:00:02 -i video.mp4 clip.gif

6. Convert gif to mp4:

ffmpeg -f gif -i clip.gif video.mp4

@susu Thank you
i´ll play with these commands today

 

[susu]

@DonManfred , can your FFMPEG lib play streaming video? If yes, it will be the most powerful video player.

 

[DonManfred]

can your FFMPEG lib play streaming video?

No. you can see the lib as a kind of starter for the ffmpeg executable (cli).
Maybe it is possible to save a stream to a video. i did not tested susus sample commandlines.

I just tried the commandline to add an overlay to a video but it seems i cant get it to work.
Maybe the ffmpeg is doing something in backgroud.. but i dont get any progress as yet. Aehm... It started output but stopped at a line i did not expect the end of output. Maybe one or more of the parameter i did not send correctly
