than the USB camera, which is a more expensive reason for it.Then there is a question, why take a picture for 7 seconds?Increase the-v parameter to view debug information:raspistill -o image.jpg -rot 80 -vYou can see a line of information inside: Time Delay:5000 . Then look at the command document and find that the default-t parameter equals 5000, which will wait 5 seconds before taking the picture.Then increase the speed of the-t parameter set a little bit faster, it is true, but in the test f

stream.Shut downand finally the release.H264 and AAC data streamsAs mentioned in this paper, rtmp push audio and video streaming package form similar to the FLV format, it can be seen, to the FMS push H264 and AAC live stream, need to first send "AVC sequence header" and "AAC sequence Header", these two data contain important coding information, without them, the decoder will not be decoded.The AVC sequence header is the Avcdecoderconfigurationrecord structure in the standard document "iso-1449
The example in this article will be implemented by reading the PC webcam video data and sending it as a live stream with the RTMP protocol. Example contains the
1, the use of FFmpeg libavdevice
2. The basic flow of video decoding, encoding and pushing
has a strong comprehensive.
To use Libavdevice related functions, you first need to register the relevant components
