Android version compile completely but apk is crash when I run on simulator or android device.

[RenHu]

Hi rockcarry, Happy New Year! and I hope everything will come out all right for New year - 2019!

I am appreciate your project fanplayer for windows, but it's not work for android. Could you pls explain me is it working on android? Because, I build everything correct step by step according to your guide and it's build successfully to make apk. But apk is crash when It run on simulator or android device. I am so urgent with this problem. So, I kindly ask you about problems for android version. I hope to get good response with you. Thanks

Same situation here. If I build android project as it comes, using the libfanplayer_jni.so that is already in the project, everything works fine and I can play a mpeg_ts streaming. Both audio and video work well and it's pretty stable.

But if I build the native code, and then test the project with that libfanplayer_jni.so, I get a segmentation fault 11. I found that error occurs in the function vdev_android_unlock(), at vdev-android.cpp, in this line: c-> cmninfos-> vpts = pts; It turns out that c->cmninfos is a NULL pointer since it wasn't initialized. I fixed that problem by adding: render->cmninfos = cmninfos in render_open() function.

Anyway, although I no longer have the segmentation fault, now the player itself is working bad. Tested with the same streaming, now the audio is choppy, and the video freezes after a few seconds.

The player as it comes doesn't work for me, because I need to play rtmps. For that reason I wanted to build with with an openssl-enabled version of ffmpeg. And finally I managed to open the rtmps, but the player has those problems.

[rockcarry]

new commit fix this issue. player update the latest code.

[rockcarry]

rtmps need openssl support. you need modify the build_ffmpeg_for_android.sh to enable openssl support for ffmpeg.

[pabloxid]

It improved a lot!

Now the only problem that I have is, when playing rtmps, the latency is extremely low, but the audio is choppy. I don't need such low latency. Is there some buffer size adjust to improve streaming stability?

Thank you very much.

try set init param avts_syncmode to 1.

and in adev-android.cpp try to modify code:

define DEF_ADEV_BUF_NUM 3

[RenHu]

Hi rockcarry, Can I get native code project for fully build on locally?

[pabloxid]

avts_syncmode is already set to 1, afaics.

I tried to increase adev buffer number and size, but audio remains always choppy. Video is kind of broken too, and it gets worse over time.

Log is plenty of such messages:

Stream is h.264 / AAC over rtmps. I also tryed mpeg_ts. I this case, audio sounds right, without any glitch, but video is slow and out of sync; log is clean, no messages about decoding errors.

[RenHu]

So, android version of Fanplayer is not good for using development?

[RenHu]

or using FFmpeg library is not correct choose for development?

[rockcarry]

@pabloxid do you have same problem when using fanplayer win32 version? when you using aac, the sound is incorrect, maybe the rtmp pusher have some problem in aac encoding. if video is slow and out of sync, you need check the audio pts and video pts is correct or not. change the av_log_set_level(AV_LOG_WARNING); AV_LOG_WARNING -> AV_LOG_TRACE to see more debug log message.

[rockcarry]

@RenHu all source code of fanplayer is put on github. which part of source code do you want to build ?

[RenHu]

android version for locally not connect internet.

[RenHu]

because I already start development for windows version, and it's very good to play over 3GB video in 5 seconds. I almost complete windows version but now try to android version but it's not working well. I need just simple android video player which is using FFMpeg library & able to play over 3GB video in 5 seconds.

[RenHu]

ofcourse I don't want not good latency android source code. I want same quality as windows version.

[rockcarry]

pls modify code, try the modifiction I said here before.

[rockcarry]

if crash problem fixed, we'd better close this issue.
