mediacodec

I have a nexus 4 with android KitKat. I tried screen recording using the following commands: adb shell screenrecord --verbose /sdcard/demo.mp4 adb shell screenrecord --bit-rate 8000000 --time-limit 30 /sdcard/kitkat.mp4 Both times, the commands returned this message: Main display is 768x1280 @60.00fps (orientation=0) Configuring recorder for 768x1280 video at 4.00Mbps ERROR: unable to create video/avc codec instance In the debug console I had open in AndroidStudio, the following log messages were shown: 02-02 18:16:29.058 176-4045/? E/OMX-VENC-720p﹕ Is component secure 0 02-02 18:16:29.058 176

I've been struggling with this issue for more than a week, and most likely it is a bug in the Qualcomm GPU/hardware video encoder . Since we are pressed to release the application, and their developer forums did not provide any feedback, I am posting it here too, hoping that someone is able to provide some clues, or even better, a workaround so that the bug in the encoder is not triggered. The application encodes from a Surface. When certain images are rendered to the surface, the encoder fails (100%) in the same place (when the frame currently being encoded is a key frame). The Logcat output

I am trying to use MediaCodec API to decode and display an MPEG2 encoded stream. I use MediaExtractor to extract the stream from an MPEG Transport Stream ( TS ). I notice that configure() of the decoder is failing on all devices that I have tried - Nexus7(2012), Nexus7(2013), Nexus10, with error code 0x80001001. The only parameter that can go wrong in using the configure() API is the MediaFormat configuration provided and this is obtained from the Android MediaExtractor . I do not understand what could be going wrong resulting in this issue getting noticed. The configuration parameters present

In my i want encode yuv data into h264 using mediacodec software codec. I use Google software encoder OMX.google.h264.encoder when i use hardware encoder[OMX.qcom.video.encoder.avc] that time it work but when i use software encoder[OMX.google.h264.encoder] it not encode file.it will give error [see in log]. what is problem i couldn’t identify. Source : mediaCodec = MediaCodec.createByCodecName("OMX.google.h264.encoder"); //mediaCodec = MediaCodec.createByCodecName(codecInfo.getName()); Log.i(TAG,"codec name : "+ mediaCodec.getName()); int mBitrate = (int) ((MainActivity.mHeight * MainActivity

I render a texture to both display and a codec input surface (from where an encoder uses it). There is a large performance variation when the texture is rendered to the display surface, and when it is rendered to the input surface of the encoder, but only on some devices, like S3 Galaxy (~10 times slower to render to encoder surface). On other devices, the speed is similar (S4, Nexus4, etc). A similar scenario can be demonstrated with Grafika and Record GL app activity. (FBO blit x2) The fps drops from ~60 to 6 only for the mentioned device, while for the other devices there is a constant rate

I am using MediaCodec to convert a .wav file to .amr . I have used following code for input and getting encoded buffer. I get the encoded file but it does not play, my input is proper as i am able to play that file in Audacity. I am using EncodeDecodeTest.java from android API test. Any pointers to potential problem are appreciated. MediaCodec codec = MediaCodec.createByCodecName(componentName); try { codec.configure( format, null /* surface */, null /* crypto */, MediaCodec.CONFIGURE_FLAG_ENCODE); } catch (IllegalStateException e) { AppLog.logString("codec '" + componentName + "' failed

I'm looking for the fastest way to take an image frame received from the MediaCodec decoder and draw it to the Android device screen. The important constraints and explanations are: Cannot use MediaPlayer. No intermediate app allowed. Must draw output frames from the MediaCodec decoder to the screen as quickly as possible (minimize latency). The available decoder output formats are as follows: ColorFormat[0] 0x00000013 COLOR_FormatYUV420Planar ColorFormat[1] 0x00000015 COLOR_FormatYUV420SemiPlanar ColorFormat[2] 0x7F000001 OMX_SEC_COLOR_FormatNV12TPhysicalAddress ColorFormat[3] 0x7FC00002 OMX
