"Go" Overview of the Android live video network transmission scheme (total five sets)

Recently studied the real-time video network transmission problem of Android, spent a lot of effort in video processing, summed up the following five sets of solutions, and compared

An example of a video transmission of the same size

Scheme	compression rate	compression/transport	Realtime	Average traffic consumption	transmission distance
sends the original YUV420 data with the camera's callback function	0	uncompressed, transfer by frame	high (20~30 fps)	High (6.5 Mbps) too scary It's o_o.	Close-up wired or wireless
send H264 hard-coded yuv420 with Mediarecorder	High (95%)	inter-frame pressure Video streaming	high (+ fps)	Low (30~70 Kbps)	can be long distance
call local H264 encoding library (JNI) to a frame Yu V420 data encoding send	high (97%)	inter-frame compression, transfer by frame	low (2 fps)	Low (up to Kbps)	Long distance
compressed with gzip library for one frame of data sent (very wonderful practice)	Higher (70%~80%)	Intra-frame compression, transfer by frame	Low (5 fps)	High (3 (Kbps)	Long distance
Compress a frame of data in JPEG mode	general (60% or so)	Intra-frame compression, transfer by frame	High (fps)	high (in Kbps)	can be long-range (bandwidth permitting)

Note: Mediarecorder has a strong hardware dependence, so different mobile phone performance is not the same, some mobile phone data transmission when there will be blocking phenomenon, real-time reduction of

In summary, Scenario 2 (Mediarecorder) and Solution 5 (JPEG) can also be considered, because my project only need to be near-distance wireless transmission, and the hardware level is not high, so chose the scenario 5

The above plan is I recently more specific and in-depth study of real-time video coding and transmission scheme summed up, I hope that the study of video transmission friends can be used to reference!
