Weird and unpredictable crash when using libx264 cross-compiled with MinGW
2 mars 2012, par DanielI'm working on a C++ project using Visual Studio 2010 on Windows. I'm linking dynamically against x264 which I built myself as a shared library using MinGW following the guide at
http://www.ayobamiadewole.com/Blog/Others/x264compilation.aspx
The strange thing is that my x264 code is working perfectly sometimes. Then when I change some line of code (or even change the comments in the file !) and recompile everything crashes on the line
encoder_ = x264_encoder_open(&param);With the message
Access violation reading location 0x00000000I'm not doing anything funky at all so it's probably not my code that is wrong but I guess there is something going wrong with the linking or maybe something is wrong with how I compiled x264.
The full initialization code :
x264_param_t param = { 0 };
if (x264_param_default_preset(&param, "ultrafast", "zerolatency") < 0) {
throw KStreamerException("x264_param_default_preset failed");
}
param.i_threads = 1;
param.i_width = 640;
param.i_height = 480;
param.i_fps_num = 10;
param.i_fps_den = 1;
encoder_ = x264_encoder_open(&param); // <-----
if (encoder_ == 0) {
throw KStreamerException("x264_encoder_open failed");
}
x264_picture_alloc(&pic_, X264_CSP_I420, 640, 480);Edit : It turns out that it always works in Release mode and when using superfast instead of ultrafast it also works in Debug mode 100%. Could it be that the ultrafast mode is doing some crazy optimizations that the debugger doesn't like ?

FFMPEG : could not run filter error
3 octobre 2013, par VigoI have static builds for FFMPEG. I run a video streaming command from the console. I get a 'could not run filter error'.
What are the generic causes of this error ? Is it an issue with the parameters passed or is it something to do with the video capturing device (in my case, Webcam) itself ? Could anyone throw some light on this ?

Linphone OSx msx264 encryption VGA takes 97% CPU, why ?
11 septembre 2013, par Maxim ShoustinI have problem and today don't know how to fix it or even from where to start.
I have Linphone application that uses msx264 plugin.
All stuff I run on OSx and my ffmpeg version installed from
port, I didn't using selfupdate for portbash-3.2# port installed ffmpeg-devel
The following ports are currently installed:
ffmpeg-devel @20130205_0+gpl2
ffmpeg-devel @20130328_0 (active)
ffmpeg-devel @20130328_0+gpl2So I compiled and build msx264, no errors.
Now I try to send video over CIP resolution VGA (640x480) and get huge delay 8-9 seconds, even self-view I see in big delay.
when I configure CIF (352x288), all seems fine.
It's really strange that self-view camera has delay 4-5 sec.
So from logs during the session I found that msx264 plugin takes 97% CPU
On PC (windows 7) the same code runs fine, even HD I don't see any problems.
What is the problem should be ?
