ffmpegFrameRecorder

[Tomasz Skulimowski]

Hi,

 I'am working with ffmpegframerecorder and recordActivity. It allows to record video with audio in AAC format. Is it possible to change it to the mp3 format. I tried:

recorder.setAudioCodec(AV_CODEC_ID_MP3);

but I receive 

08-28 20:32:59.939: W/System.err(30703): com.googlecode.javacv.FrameRecorder$Exception: avcodec_find_encoder() error: Audio codec not found.

Best regards,

Tomasz

Hello,

We need a version of FFmpeg that has been built with libmp3lame for that
to work, and that doesn't seem to be the case of the version you are
using unfortunately..

hi Samuel:

I follow this site for sending the live video from android to other server.

http://www.walking-productions.com/notslop/2013/01/16/android-live-streaming-courtesy-of-javacv-and-ffmpeg/

in that they are using this code 

recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);

recorder.setFormat("flv");

recorder.setSampleRate(sampleAudioRateInHz);

// Set in the surface changed method

recorder.setFrameRate(frameRate); while i am checking the video at server side it says: Sorenson-H263 is not compatible with HLS. You should have H264-encoded video. then i changed that code like this way: recorder.setVideoCodec(13); recorder.setFormat("mp4"); recorder.setPixelFormat(avutil.PIX_FMT_YUV420P); recorder.setFrameRate(12); recorder.setVideoBitrate(10 * 1024 * 1024); i am getting this error. "com.googlecode.javacv.FrameRecorder$Exception: avcodec_find_encoder() error: Video codec not found".

You need to call  recorder.setVideoCodec(AV_CODEC_ID_H264)  if you want to use the H.264 codec. The number 13 isn't the H.264 codec.

Is there any separate android application which will transfer live video of h264 type video from android camera to server? please send me  if any  code is available with you!

That's not possible. The symbol "avutil.PIX_FMT_YUV420P" does not exist
in that version. Please try again with JavaCV 0.7.

The RecordActivity.java sample should do that just fine:

Hi,
I've encountered the very same problem here, but 'till now, I'm unable to solve it ... .
I'm using the same project example as you did: walking-productions.com
and updated javacv/cpp to Version 0.8.

Now, when trying to switch to H.264 Codec, as Samuel suggested, via: recorder.setVideoCodec(AV_CODEC_ID_H264);
Eclipse returns (hovering above that line):

AV_CODEC_ID_H264 cannot be resolved to a variable

why doesn't this work?
Can i replace AV_CODEC_ID_H264 by it's variable?

When trying the same with:

 recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);

[ + import org.bytedeco.javacpp.presets.avcodec; ]


AV_CODEC_ID_H264 still does not get resolved.

Any ideas what to do, in order to get it resolved?
If not, where can i find the correct IDs for the usable codecs?

Thanks,
Martin

AV_CODEC_ID_H264 still does not get resolved.

You're going to need to

    import static org.bytedeco.javacpp.avcodec.*;

for that to work!
