  Added two new properties that expose how  and  elements are created, to give users direct control over those elements. Fixes #700.

• Muxing Android MediaCodec encoded H264 packets into RTMP

  31 décembre 2015, par Vadym

  I am coming from a thread Encoding H.264 from camera with Android MediaCodec. My setup is very similar. However, I attempt to write mux the encoded frames and with javacv and broadcast them via rtmp.

  I am not, by any means, an expert in H264 or video encoding. I know that the encoded frames that come out from MediaCodec contain SPS NAL, PPS NAL, and frame NAL units. I’ve also written the MediaCodec output into a file and was able to play it back (I did have to specify the format and framerate as otherwise it would play too fast).

  My assumption is that things should work (see how little I know :)). Knowing that SPS and PPS are written out, decoder should know enough. Yet, ffprobe fails to recognize codec, fps, and other video information. Do I need to pass packet flag information to FFmpegFrameRecorder.java:record() function ? Or should I use direct buffer ? Any suggestion will be appreciated ! I should figure things out with a hint.

  PS : I know that some codecs use Planar and other SemiPlanar color formats. That distinction will come later if I get past this. Also, I didn’t go the Surface to MediaCodec way because I need to support API 17 and it requires more changes than this route, which I think helps me understand the more basic flow. Agan, I appreciate any suggestions. Please let me know if something needs to be clarified.

  Update #1

  So having done more testing, I see that my encoder outputs the following frames :

  000000016742800DDA0507E806D0A1350000000168CE06E2
  
  0000000165B840A6F1E7F0EA24000AE73BEB5F51CC7000233A84240...
  
  0000000141E2031364E387FD4F9BB3D67F51CC7000279B9F9CFE811...
  
  0000000141E40304423FFFFF0B7867F89FAFFFFFFFFFFCBE8EF25E6...
  
  0000000141E602899A3512EF8AEAD1379F0650CC3F905131504F839...
  
  ...

  The very first frame contains SPS and PPS. From what I was able to see, these are transmitted only once. The rest are NAL types 1 and 5. So, my assumption is that, for ffprobe to see stream info not only when the stream starts, I should capture SPS and PPS frames and re-transmit them myself periodically, after a certain number of frames, or perhaps before every I-frame. What do you think ?

  Update #2

  Unable to validate that I’m writing frames successfully. After having tried to read back the written packet, I cannot validate written bytes. As strange, on successful write of IPL image and streaming, I also cannot print out bytes of encoded packet after avcodec_encode_video2. Hit the official dead end.

• Using ffmpeg on Windows, what is the command to capture hardware encoded H264 stream from Logitech c930e

  2 mai 2015, par Jeff

  I am using ffmpeg on Windows 8 and I would like to capture the built-in H264 hardware encoded stream from the Logitech c930e camera. The H264 built-in encoded stream is part of the UVC 1.5 interface.

  Using this command I have noticed that the c930e exposes two video pins through DirectShow : 0 and 1.

  ffmpeg -report -list_options true -f dshow -i video="Logitech Webcam C930e"

  [dshow @ 0000000002d89360]  Pin "Capture" (alternative pin name "0")

  [dshow @ 0000000002d89360]  Pin "Capture" (alternative pin name "1")

  It doesn’t seem to matter if I choose Pin 0 or 1, I still get raw video from the Logitech c930e webcam. On Linux, the supposed command involves v4l2, but this does not appear to exist in the default Windows version of ffmpeg from http://ffmpeg.zeranoe.com/builds/

  Does the default Windows build of ffmpeg support the direct capture of the UVC interface ?

  This is the closest I have gotten on this journey, but still isn’t quite right :

  ffmpeg -report -f dshow -i video="Logitech Webcam C930e" -s 1920x1080 -r 30 -video_pin_name 1 -vcodec H264 -c copy -f mp4 Logitechc930eFeed.mp4

  As of April 17, 2015 I am still trying to figure this out and have two new pieces of info.

  I found this interesting article on Logitech’s website instructing the user to change the default Logitech driver to the generic USB Video Device driver :
  https://support.logitech.com/en_us/article/Install-native-UVC-drivers-for-your-Logitech-webcam?product=a0qi00000069v0MAAQ#

  I also found that my C930e had an older firmware (8.0.866), and Logitech recommends updating the firmware to 8.0.875 to fix an unspecified UVC H.264 issue.

  So now I have the latest firmware, and am using the generic "USB Video Device" on Windows 8.1.

  ffmpeg -list_devices true -f dshow -i

  which gives this output :
