aac-eld decode linux
28 février 2013, par bernardI'm was in Vietnam and tried to learn Vietnames.
The difficult thing is to learn the pronunciation and I made an Android App to record voices. Vietnamese people are very nice and I collected more than 500 sound files.Now I try to make a language learning app. To do that I try to reduce noise and normalize volume.
I have chosen the following settings :
this.recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
this.recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC_ELD);
this.recorder.setAudioEncodingBitRate(96000);
this.recorder.setAudioSamplingRate(44100);(cordova AudioPlayer.java - default settings are crap)
Now I have a problem. I'm not able to open the files with audacity or ffmpeg.

Overlaying jpg onto Mp4 using -VF
16 février 2013, par bruxI am using the following command to overlay a jpg :
ffmpeg -i in.mp4 -vf "movie=bb.png [movie] ; [in] [movie] overlay=0:0 [out]" -vcodec libx264 -acodec copy out.mp4
This works as expected with the first file (listed below) but it doesnt work with the second file. There is no error when I try with the second file, rather is creates an unusually large file that would not open :

If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
It’s like a few black dots on a blank screen :ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov
what could be the reason for this display ?
