i.MX6 h.264网络传输问题（已解决）

houweitao2835

我用i.MX6 SDB板测试VPU h.264，BSP版本为L3.0.35_4.1.0_130816,系统用的是min_profile
在提供的例子中有unit_tests/autorun-vpu.sh  加以config_enc 、config_dec、config_net，通过修改config_enc、config_dec都实现了自定义的编解码功能。

下面是修改后的config_net文件

# Write your options here!
#以下操作用来做什么？没有用到，有些不懂
# Type of operation encode or decode; encode = 1, decode = 2
operation=2

# read input from file. For network, leave blank. If not specified for encode
# then default is camera
input=

# write output to file. For decode, if not specified, then default is LCD
output=

# port number for server to listen. If none specified, default is 5555
port=

# format; 0 - MPEG4, 1 - H.263, 2 - H.264, 3 - VC1, 7 - MJPG
format=2

# mp4Class; 0 - MPEG4, 1 - DIVX 5.0 or higher, 2 - XVID, 5 - DIVX 4.0
mp4Class=

# rotation angle (0, 90, 180, 270). Do not specify anything if not needed.
rotation=90

# ipu_rot, 1 - Enable IPU rotation and disable VPU rotation when output
# to LCD for display
ipu_rot=

# chromaInterleave, 1 - CbCr is interleaved.
# Suggest to enable this option since performance is better.
chromaInterleave=1

# prescan, 1 - Enable prescan
# Suggest to enable this option since decoder performs scanning stream buffers
# to check whether data is enough to preventing decoder hanging.
prescan=1

# count, number of frames to encode or decode
count=

# deblocking . 1 - Enable deblock
deblock=

# mirroring (0, 1, 2 , 3)
mirror=

# width, display width for decoding
width=

# height, display height for decoding
height=

# bitrate. default is auto
bitrate=

# gop size. default is 0
gop=

# This option specifies the end of option list for one instance
# Each option list must be end with this option. This is mandatory.
end

#我只使用以下操作来压缩传输码流
# Type of operation encode or decode; encode = 1, decode = 2
operation=1

# read input from file. leave blank for network. If not specified for encode
# then default is camera
input=test.yuv

# write output to file. For decode, if not specified, then default is LCD
output=test.264

# send encoded data to server. specify server ip address
ip=192.168.100.13

# port number of server. If none specified, default is 5555.
port=1234

# format; 0 - MPEG4, 1 - H.263, 2 - H.264, 3 - VC1
format=2

# rotation angle (0, 90, 180, 270). Do not specify anything if not needed.
rotation=

# chromaInterleave, 1 - CbCr is interleaved
# Suggest to enable this option since performance is better.
chromaInterleave=1

# count, number of frames to encode or decode
count=

# deblocking . 1 - Enable deblock
deblock=

# mirroring (0, 1, 2 , 3)
mirror=

# width for encoding. This will be the capture/yuv image width
width=240

# height for encoding. This will be the capture/yuv image height
height=320

# bitrate. default is auto
bitrate=0

# gop size. default is 0
gop=0

# This option specifies the end of option list for one instance
# Each option list must be end with this option. This is mandatory.
end

现在要测试config_net，本地数据test. yuv压缩为h.264码流test.264，然后传输到PC(IP:192.168.100.13)，PC端通过wireshark看接收到了数据，但如何验证数据的正确性，PC这边该用什么播放器？或者要自己写代码来验证？

我自己写了一个小程序，用RTP协议，将一个文件test.264传输到PC上，PC端用VLC播放器可以播放视频。
但config_net用的是什么协议，看不懂，

我找到这个unit_tests的源码了，我自己看看。

楼主你好，这里是一些参数说明，你就是你在播放视频或图像的时候需要设置参数的。
