h.264

Is there a way to access libstagefright.so directly to decode H.264 stream from JNI layer on Android 2.3 or above? If your objective is to decode an elementary H.264 stream, then your code will have to ensure that the stream is extracted, the codec-specific-data is provided to the codec which is primarily SPS and PPS data and frame data along with time-stamps is provided to the codec. Across all Android versions, the most common interface would be OMXCodec which is an abstraction over an underlying OMX component. In Gingerbread (Android 2.3) and ICS (Android 4.0.0), if you would like to create

What is the meaning of Base64 decoded bytes in sprop-parameter-sets in SDP for a h264 stream? How can I know the video size from this example? SDP example: sprop-parameter-sets=Z0IAKeNQFAe2AtwEBAaQeJEV,aM48gA== First part decoded from Base64 to Base16: 67 42 00 29 E3 50 14 07 B6 02 DC 04 04 06 90 78 91 15 Second part (comma separated): 68 CE 3C 80 ANSWER: Fetching the dimensions of a H264Video stream Jonathan Websdale The spec you require is available for free download from the ITU website here:- H.264 (03/10) Select the freely downloadable PDF and you'll find the format detailed in section 7

I'm trying to capture H264 stream from locally installed Logitech C920 camera from /dev/video0 with Gstreamer 1.0 v4l2src element. v4l2-ctl --list-formats shows that camera is capable to give H264 video format: # v4l2-ctl --list-formats ioctl: VIDIOC_ENUM_FMT ... Index : 1 Type : Video Capture Pixel Format: 'H264' (compressed) Name : H.264 ... But pipeline # gst-launch-1.0 -vvv v4l2src device=/dev/video0 ! video/x-h264, width=800, height=448, framerate=30/1 ! fakesink keeps giving me not-negotiated (-4) error: /GstPipeline:pipeline0/GstV4l2Src:v4l2src0.GstPad:src: caps = video/x-h264, width=

I created a h264 raw video file, and I was able to mux it with Android MediaMuxer on Android 4.3 and up. Now I need to support Android versions 4.1 and 4.2. I found Jcodec. And there is an example for doing this: https://github.com/jcodec/jcodec/blob/master/samples/main/java/org/jcodec/samples/mux/AVCMP4Mux.java But I'm getting java.nio.ReadOnlyBufferException exception at line 70: H264Utils.encodeMOVPacket(data); I guess this code is not for Android? How do I fix this. Can someone familiar with Jcodec help on this? xy uber.com I gave up on Jcodec. It exposes too many codec internal stuff, and

I have gotten the SPS in NALU ( AVC Decoder Configuration Record ), and trying to parse the video width / height from it. 67 64 00 15 ac c8 60 20 09 6c 04 40 00 00 03 00 40 00 00 07 a3 c5 8b 67 80 This is my code parse the SPS but gets the wrong values. pic_width_in_mbs_minus1 is 5, and pic_height_in_map_units_minus1 is 1. Actually the video is 512 X 288px typedef struct _SequenceParameterSet { private: const unsigned char * m_pStart; unsigned short m_nLength; int m_nCurrentBit; unsigned int ReadBit() { ATLASSERT(m_nCurrentBit <= m_nLength * 8); int nIndex = m_nCurrentBit / 8; int nOffset = m

Does anyone know how to decode H.264 video frame in Java environment? My network camera products support the RTP/RTSP Streaming. The service standard RTP/RTSP from my network camera is served and it also supports “RTP/RTSP over HTTP”. RTSP : TCP 554 RTP Start Port: UDP 5000 Or use Xuggler . Works with RTP, RTMP, HTTP or other protocols, and can decode and encode H264 and most other codecs. And is actively maintained, free, and open-source (LGPL). I think the best solution is using "JNI + ffmpeg". In my current project, I need to play several full screen videos at the same time in a java openGL
