VIM3

@goenjoy @superceleron @tenk.wang @jasonl

  1. I have audio format data which is audio/mpeg-L2 type.
  2. When i am opening with CreateBytype(codecLooper,mim) it’s giving codec null.
  3. When I am opening with CreateByComponentName(codecLooper,mim,false) it’s giving config issue.
  4. How we can use audio codec for the play audio stream.
  5. How we can enable audio/mpeg-L2 in khadas source because this format not available in the source code.

@jasonl
I am getting mpeg2 byte array data which i am creating codec using MediaCodec::CreateByType(codecLooper, mime.c_str(), false/encoder/);
that time failed to create codec when i am trying to create by using MediaCodec::CreateByComponentName(codecLooper, “OMX.google.mpeg2.decoder”)
that time it’s creating codec but codec init failed due to mpegL2 not support for the audio format.

From what i remember mpegL2 is not supported in the android 9 sdk.
and it think it is this codec for the L2 OMX.google.mp2.decoder.
I will add it in my next build, but no promises it will work!

@superceleron

I have check it’s not working.

  1. When i am opening direct file with mediaplayer or other player in khadas which is available that’s working audio and video.
  2. But when i am trying to open with media codec
    mCodec = MediaCodec::CreateByType(codecLooper, mime.c_str(), false);
    it’s showing failed to create mediacode.
    mime = “audio/mpeg-L2”
  3. So how can i open mediacodec and init so that it should work because it’s working on the different app which is video player.
