Hi All,<br><br>In my project I am developing an application which decodes h.264 video using hardware if it finds libva and a compatible hardware, and it fallbacks to software mode (the normal ffmpeg mode) in case the library is not found or hardware doesn't support H.264 profile. But I am having some unusual error on my opensuse machine with Nvidia Graphics Card Quadro FX 4600.<br>
<br>libva: libva version 0.31.1-sds1 <br>Xlib: extension "XFree86-DRI" missing on display ":0.0". <br>libva: va_getDriverName() returns 0 <br>
libva: Trying to open /usr/local/lib/va/drivers/nvidia_drv_video.so <br>vainfo: vdpau_driver.c:235: vdpau_do_Initialize: Assertion `vdp_status == VDP_STATUS_OK' failed.<br><br>I searched the internet and found out that my Graphics card doesn't support vdpau. But why is libva not returning any error code in vaInitialize and why it is forcing the application to abort ? I looked into the files and then found out that in sysdeps.h ASSERT is defined to abort even if it debugging is disabled in the library.<br>
<br>#if USE_DEBUG<br># define ASSERT assert<br>#else<br># define ASSERT(expr) do { \<br> if (!(expr)) { \<br> vdpau_error_message("Assertion failed in file %s at line %d\n", \<br>
__FILE__, __LINE__); \<br> abort(); \<br> } \<br>
} while (0)<br>#endif<br><br>Isn't it should be defined like this<br><br><br>#if USE_DEBUG<br># define ASSERT assert<br>#else<br># define ASSERT(expr) \<br> if (!(expr)) { \<br>
vdpau_error_message("Assertion failed in file %s at line %d\n", \<br> __FILE__, __LINE__); \<br> } \<br>
#endif<br><br>I am a newbie, have never written any open source code. Please tell me what is the problem if it is defined like that? and if there is no problem then isn't the abort mechanism should be removed from the vdpau-video with debugging disabled<br>
