video after ffmpeg command conversion is not playing on windows
10 décembre 2015, par Hemant KumarI am stuck at a very weird and complex problem, hoping if anyone know the solution :
I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.
I am using following codec :
['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']I work on linux and using html5 player on my website. I am converting video in mp4 format.
Input :
ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4

Issue when combining 2 video files [after matching the specs]
6 décembre 2015, par RuneBasically I got a .mp4 and a .flv file which I want to concatenate (the .mp4 should be the intro).
So after having asked a previous question regarding this I went ahead and converted the intro video to an .flv with matching specifications of the second video.
First I got the specifications of the second (.flv) video using ffprobe. This was the output :

I then concatenate the ouputted intro file with my main video file using the following command (tmp.txt contains the 2 files) :

It starts off playing the intro just fine.
However, when the intro is finished the video freezes while the sound of the actual video continues for the entire duration of the video.Thus in conclusion what is lacking is the video of the second vid (the audio is fine).
I’m new at using ffmpeg but I’ve tried my best to solve this, which is why I’m asking for your help.
I’d certainly appreciate if someone could help me out.

Tap to record like in vine using javacv
8 décembre 2015, par human123I am trying to implement a tap to record feature like in vine. A sample for handling recording (not touch to record) provided in javacv is https://github.com/bytedeco/javacv/blob/master/samples/RecordActivity.java. I am trying to modify it so that in onPreviewFrame method frames are added to buffer only when user has his finger placed on screen. These frames are then tried to be combined into final video in stopRecording method.
The issue is that if I set the timestamp as given in below code snippet (in stopRecording method)
if (t > recorder.getTimestamp())
{
recorder.setTimestamp(t);
}the behavior is as below
Case 1
If I tap on screen to record for 2 seconds and take the finger away from screen for 3 seconds and then again place finger back on screen to record for another 4 seconds the resulting video is like,
For 1st 2 seconds video has recorded content. For next 3 seconds (time when finger is put away from screen). video just shows the last frame recorded when finger was placed on screen last. Then the video has recorded video content for next 4 seconds. So there seems to be an issue in handling video recording when finger is removed from screen.
Case 2
Next I removed the code setting time stamp to recorder(the code snippet given above) in stopRecording method.
Now the resulting video (for the same steps tried in case 1) does not contain the middle 3 seconds(which is what is required) when finger was taken away from screen. But video is playing at a faster rate. So it seems that we need to set time stamp so that video plays at normal rate.
Full code of my activity is given below. (Please note that video recording is mainly handled from onPreviewFrame and stopRecording methods)

Suggestion 1 - Estimate average frame rate

}Change made was adding t += 1000000 / frameRate ; But this caused the video to freeze (as in case 1 described above) in portions when finger was placed away from screen.
