Native crash, probably in "destructor" about ffmpegmediaplayer HOT 13 CLOSED

I have exactly the same issue, any progress on this problem?

from ffmpegmediaplayer.

Nope, but you may Paypal or flattr the author. Maybe that will make him
feel obliged to fix it? ;)

I'm flattring him, anyway.

I haven't been responding to bug reports as of late since I've been in the middle of rewriting the entire FFmpeg portion of the code to improve buffering and to use OpenSLES instead of AudioTrack. While I do appreciate donations (because I spend an insane amount of time on this library for next to nothing) they aren't required to get an issue fixed. With that said, adding "me to" to bug reports generally irritates me and bumps that issue to the bottom of my priority list :)

I swear I didn't metoo it, man! :-)

Sorry, I just want to ask the status of this issue.

I've fixed this issue.

Reason: There are 2 methods that run in separate thread: player_prepare & player_decode. Your code only handle "player_decode" thread. Every time ffmpegplayer stop (call reset function), the pointer of state will be released, but "player_prepare" thread is still running. This thread try to use state pointer but address not mapped, so it throws signal 11 error.

Solution: Handle "player_prepare" thread, check state every time using it.

You can see source code here: https://gist.github.com/luhonghai/76e6a3de31f83bf80379

(Coffeecatch here: https://github.com/xroche/coffeecatch)

Sorry for my bad english. I hope it will be useful.

Whoa! Thanx a lot!

One more question. Since you're migrating to openal, I guess I will not be
able to use Android eq anymore, right? Does openal have its own effect
engine? Parametric eq, by any chance?

Just to note. If someone else like me gonna try to use @luhonghai fixed ffmpeg_mediaplayer.c (which seems to be really fixed, at lease I couldn't reproduce the bug again), you need to do couple things:
You need to recompile the project, so

1. Clone it
2. Execute (android update project --path . --target android-22) inside /fmp-library folder.
3. Follow the instructions to update local.properties
4. Replace ffmpeg_mediaplayer.c file inside /fmp-library/jni/player folder.
5. Open ffmpeg_mediaplayer.h file and add this line

pthread_t prepare_thread;

inside State struct, so it looks like this

 typedef struct State {
    .......some code here
    int loop;

 pthread_t decoder_thread;
 pthread_t prepare_thread;
 int abort_request;
 int paused;
    .......some code here
 }

1. Clone https://github.com/xroche/coffeecatch and copy coffeecatch.c, coffeecatch.h, coffeejni.c, coffeejni.h files inside /fmp-library/jni/player folder.

2. Open Android.mk file and edit LOCAL_SRC_FILES, so it looks like this

   LOCAL_SRC_FILES := wseemann_media_MediaPlayer.cpp
   mediaplayer.cpp
   ffmpeg_mediaplayer.c
   player.c
   coffeecatch.c
   coffeejni.c

3. Now you will be able to compile the libraries and get all .so files. Yeeeiii (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

@shliama Thanks for guideline. I have a problems when following step to recompile.

I got this errors.

Do you have any clue?

from ffmpegmediaplayer.

@anop72 Hi, unfortunately I'm not that good with ndk, so I have no clue what this error-trace mean :(
But, maybe it connected with ndk version, I was using android-ndk-r8e for mac, and also everything that I was describing in the instruction was happening in the /fmp-library folder - not in /gradle/fmp-library (if it really matter)

from ffmpegmediaplayer.

@shliama I see. It my fault because wrong dir.

Everything fine and it's work!

from ffmpegmediaplayer.

@anop72 So what did you do to fix it? I'm getting exactly the same error.

from ffmpegmediaplayer.

This should be fixed in version 1.0.1.
