How to play streaming video (and audio)?

[misol101]

Hello,

your setDataSource doc states "Sets the data source (file-path or http/rtsp URL) to use", but it seems that it simply tries to open the supplied datasource as a file (with av_open_input_file), so it cannot play streams or remote files.

Are you working on enabling this as well in your library? If not, do you have any pointers on how it could be done?

Thanks for any help!

config ffmpeg:
jni/libffmpeg/config.h

-CONFIG_HTTP_PROTOCOL 0
-CONFIG_TCP_PROTOCOL 0

+CONFIG_HTTP_PROTOCOL 1
+CONFIG_TCP_PROTOCOL 1

jni/libffmpeg/config-arm.mak:
-!CONFIG_TCP_PROTOCOL=yes
-!CONFIG_HTTP_PROTOCOL=yes

+CONFIG_TCP_PROTOCOL=yes
+CONFIG_HTTP_PROTOCOL=yes

Thanks, but after a clean build with your changes I get:

/home/misol/Android/android-ndk-r5c/samples/havlenapetr-FFMpeg-7c27aa2/obj/local/armeabi/libavformat.a(allformats.o): In function av_register_all': /home/misol/Android/android-ndk-r5c/samples/havlenapetr-FFMpeg-7c27aa2/jni/libffmpeg/libavformat/allformats.c:237: undefined reference tohttp_protocol'

make: *** [/home/misol/Android/android-ndk-r5c/samples/havlenapetr-FFMpeg-7c27aa2/obj/local/armeabi/libffmpeg_jni.so] Error 1

Can you help out again?

Finally managed to compile with tcp/hhtp on, using the following (with a few ugly hacks, I'm no make build expert):

diff -r jni/libffmpeg/config-arm.mak ../../samples/havlenapetr-FFMpeg-7c27aa2/jni/libffmpeg/config-arm.mak

Unfortunately (and like I suspected) there is no difference when setDataSource is called (av_open_input_file fails, which seems to make sense since it seems to work with files only?).
tsingien, how do I actually make any use of my now "http/tcp-enabled" library?

[tsingien]

maybe you should call
./configure --your parameters such as --enable-network --enable-http etc.
on linux.

this command will create config.h and config.mak. then copy config options to your havlenapetr project.

[misol101]

But are you saying that remote streams and urls will in fact play "automagically" as long as my ffmpeg config is right? That av_open_input_file (as called in mediaplayer.cpp) will open and play these with no other modifications needed?
Is that working for you?

[tsingien]

yes.

Will u please give me your email address? I'll send my config.h and config.mak to u.

[misol101]

Great, thanks! Send to ******@yahoo.com

[easycui]

I also have such problem. Do you mind send me config.h and config.mak? My email is easy.cuiyuxin@gmail.com Thanks.

I'm getting the following errors updating the config files. Could you please also send me the config files? (_@_*.com)
/network.h:69: : redefinition of 'struct __kernel_sockaddr_storage'
/network.h:83: error: redefinition of 'struct addrinfo'

I just want to play an rtsp h264 HiP stream on 2.2 Android tablets.
Default Android MediaPlayer has at least 10s buffering delay and I need to reduce it.
Using ffmpeg with jni seems to be, at that time, the only way to reduce it.

I'm getting the following errors updating the config files.

I build with configuration is successfull.

/libffmpeg/config.h
#define CONFIG_NETWORK 1
#define CONFIG_HTTP_PROTOCOL 1
#define CONFIG_TCP_PROTOCOL 1
#define CONFIG_RTMP_PROTOCOL 1
#define CONFIG_RTP_PROTOCOL 1
#define CONFIG_UDP_PROTOCOL 1
#define HAVE_STRUCT_SOCKADDR_STORAGE 1
#define HAVE_STRUCT_ADDRINFO 1
#define HAVE_SOCKLEN_T 1

---

libffmpeg/config.mak
CONFIG_NETWORK=yes
CONFIG_HTTP_PROTOCOL=yes
CONFIG_TCP_PROTOCOL=yes
CONFIG_RTMP_PROTOCOL=yes
CONFIG_RTP_PROTOCOL=yes
CONFIG_UDP_PROTOCOL=yes
HAVE_STRUCT_SOCKADDR_STORAGE=yes
HAVE_SOCKLEN_T=yes
HAVE_STRUCT_ADDRINFO=yes

But It does not play rtsp. Please let me know, why is it?

[tsingien]

I never test rtsp stream. http is ok.

[kietcao]

Do You use http with m3u8? Please send me link to testing?

[xccloveny]

@kietcao can you send me the config.sh config.h and config.mak? xccloveny@gmail.com
Thank you very much!

[xccloveny]

@misol101 can you send me the config.sh config.h and config.mak? xccloveny@gmail.com
Thank you very much!
I have the same problem,maybe you had done this now :）,please give me some advice.
