Fatal signal 8 (SIGFPE) #338

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

The problem is explain on this 
link:https://groups.google.com/forum/#!topic/javacv/jFmzwQa_sxg

What version of the product are you using? On what operating system?

One week ago download your project and try it on Android 4.2.2.

Please provide any additional information below.

There are two files on attach a video and  an activity class. The video that 
record by javacv with mp4 format and AV_CODEC_ID_MPEG4 video codec. And 
activity is a simple my class that try file push to server by rtmp protocol.
Actually I push video by your sample class that named RecordActivity, but 
Samuel wanted data to me.

Sorry for my english.

Thaks,

Thanks! Does the problem happen if we record to file as well?

No , just when stream to server.

Ok, sounds like this isn't going to be simple to debug. Can you send all the 
info you get in the log with the SIGFPE? Thanks

The error is that;
07-15 16:13:48.008: A/libc(8603): Fatal signal 8 (SIGFPE) at 0x0000219b 
(code=0), thread 8620 (AsyncTask #1)

When get data from came buffer and start stream the app killed.

Also I try streaming by ffmpeg on terminal. The result is on attach, hope it 
help.

Thanks,

So it works fine on the desktop? Can you find a way to reproduce the error on 
the desktop?

Previous message there were two screenshot, first is with mpeg format seem send 
data without error but i cannot watch stream from server so I don't know if 
everything is ok, the other is with mp4 format and give this error

Could not write header for output file #0 (incorrect codec parameters ?): 
Operation not permitted

And the error from desktop seem different.

Thanks,

So, let's see, do these problems only happen with RTMP? I don't think the RTMP 
protocol supports any other codec than FLV1 and H264, so it may be "normal" 
that it doesn't work with other codecs than those two. 

Does everything work properly with both FLV1 and H264?

Original comment by samuel.a...@gmail.com on 16 Jul 2013 at 1:34

GoogleCodeExporter commented 9 years ago 
Everything is ok just for FLV1 otherwise give same error.

Thanks,

Original comment by alirz...@gmail.com on 16 Jul 2013 at 10:20

GoogleCodeExporter commented 9 years ago 
What about H264?

Original comment by samuel.a...@gmail.com on 17 Jul 2013 at 2:04

GoogleCodeExporter commented 9 years ago 
Give same error

Original comment by alirz...@gmail.com on 17 Jul 2013 at 2:10

GoogleCodeExporter commented 9 years ago 
Well, if it doesn't work with the `ffmpeg` command then it's a bug in FFmpeg, 
and it's not related to JavaCV. You'll have to ask the authors of FFmpeg about 
that.

GoogleCodeExporter commented 9 years ago 
Given the lack of feedback, I'm guessing this is an issue with FFmpeg itself. 
If you posted a bug report upstream about that, please provide a link here, 
thanks!

Sir, I face the same issue too. I am trying this on Samsung galaxy tab P620 
having 4.0.3 android api. But this error is reproduced when the server to which 
the stream has to be sent to is not open (that is the server is not up and 
running). Please find the code snippet that causes the error, though since 
there is no exception thrown i believe, it is not even get caught in the 
exception i have put. Please assist.

Error: Fatal signal 8 (SIGFPE) at 0x000062d1 (code=0) (this is under tag: libc)

Thanking you

P.S: the link used is: 
ffmpeg_link = "rtmp://myusername:mypassword@IP_ADDRESS:1935/live/" + video_name;

and the following:
recorder.setFormat("rtsp");
recorder.setVideoCodec(28);

@hearbeat Do you get the same behavior when using ffplay from the command line?

Original comment by samuel.a...@gmail.com on 5 Feb 2014 at 9:14

GoogleCodeExporter commented 9 years ago 
No sir, i get it when i press the start button to record the video. It does 
work for some few seconds and then it stops with the fatal sig error. 
recorder.start also doesnot throw FFMPEG.Exception error, audioThread.start 
also doesnot throw any error. The code snippet i have attached gets called when 
audioThread.start() is called. And this line is right after the 
recorder.start() method.

Please try with ffmpeg on the command line.

This all sounds like bugs in FFmpeg. Could you retry again with the latest 
version and JavaCV 0.10? Thanks!

I'm experiencing this same problem with the android arm libs from JavaCV 0.10. 
Works fine with the osx 64 libs.

Hi, I have the same issue.  A/libc﹕ Fatal signal 8 (SIGFPE) at 0x00005523 
(code=-6), thread 21960 (Thread-2372) 
=========
if (recorder != null && recording) {
            recording = false;
            Log.v(LOG_TAG, "Finishing recording, calling stop and release on recorder");
            try {
                recorder.stop();
                recorder.release();
            } catch (FFmpegFrameRecorder.Exception e) {
                e.printStackTrace();
            }
            recorder = null;
=========
on recorder.stop(); (recorder - FFmpegFrameRecorder)
Sometimes it work, but sometimes crashing

me@blackcat95.ru Sounds like a threading issue... Can you reproduce the same 
thing on Java SE? It's easier to debug than Android. Thanks!

I think problem in arm libs (#20) and reproduce on Java SE will not help.

So, is it a bug in GCC? Or in FFmpeg?

FFmpeg

So, could you report that upstream?

And post a link here for reference? Thanks!
