multiple vaapi pipelines
Locked
 
|
Hello, I am writing and application which creates up to 12 encoding pipelines using vaapih264enc. It is working fine on Intel with i965 driver but it is very unstable on AMD using mesa gallium radeonsi driver. On radeonsi I can run up to 16 following pipelines as a separate gst-launch: gst-launch-1.0 videotestsrc ! video/x-raw,width=1280,height=1024 ! vaapih264enc ! testsink gst-launch-1.0 videotestsrc ! video/x-raw,width=1280,height=1024 ! vaapih264enc ! testsink \ videotestsrc ! video/x-raw,width=1280,height=1024 ! vaapih264enc ! testsink \ videotestsrc ! video/x-raw,width=1280,height=1024 ! vaapih264enc ! testsink \ videotestsrc ! video/x-raw,width=1280,height=1024 ! vaapih264enc ! testsink Setting pipeline to PAUSED ... Pipeline is PREROLLING ...

You probably want to install libglib2.0-0-dbg to resolve the "??" Can you open a bug attaching full GST_DEBUG log, dmesg output (to get some info on the driver and kernel) and mesa version (or glxinfo output) ? And output of "thread apply all bt" when it crashes.

It looks like the radeonsi cannot allocate enough surfaces, perhaps it is a bug in the driver. On the other hand gstreamer-vaapi is not handling nicely this surface exhaustion. In this case it would be nice to have the backtrace with symbols, as Julien said. vmjl > > > > Vainfo output: > > > > libva info: VA-API version 0.40.0 > > libva info: va_getDriverName() returns 0 > > libva info: User requested driver 'radeonsi' > > libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/ > > radeonsi_drv_video.so > > libva info: Found init function __vaDriverInit_0_40 > > libva info: va_openDriver() returns 0 > > vainfo: VA-API version: 0.40 (libva ) > > vainfo: Driver version: mesa gallium vaapi > > vainfo: Supported profile and entrypoints > > VAProfileMPEG2Simple : VAEntrypointVLD > > VAProfileMPEG2Main : VAEntrypointVLD > > VAProfileVC1Simple : VAEntrypointVLD > > VAProfileVC1Main : VAEntrypointVLD > > VAProfileVC1Advanced : VAEntrypointVLD > > VAProfileH264ConstrainedBaseline: VAEntrypointVLD > > VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice > > VAProfileH264Main : VAEntrypointVLD > > VAProfileH264Main : VAEntrypointEncSlice > > VAProfileH264High : VAEntrypointVLD > > VAProfileH264High : VAEntrypointEncSlice > > VAProfileNone : VAEntrypointVideoProc > > > > What is the difference between running it as a single or separate > > processes in relation to vaapi?
