[PATCH] demux_rtp.cpp: Don't initialize more than one audio subsession
by Carl Eugen Hoyos 25 Sep '07

25 Sep '07

Hi! If an rtsp stream contains more than one audio stream, both are initialized in current demux_rtp.cpp. This leads to visible picture(!) corruption. Attached patch fixes this by preventing initialization of more than one audio stream. Please comment, Carl Eugen PS: I did not succeed in producing a hack that would allow to change the audio streams while playing (after a hard coded time for example), so atm, applying this patch would not remove a feature.

Recent regression in FreeMediaType
by Alan Nisota 08 Sep '07

08 Sep '07

The changes to how AM_MEDIA_TYPE is handled about 2 weeks ago seems to be a bit broken. Specifically, in FreeMediaType, this code: if (pMediaType->pUnk) { pMediaType->pUnk->vt->Release(pMediaType->pUnk); pMediaType->pUnk = NULL; } (well the 'Release') causes a segfault with CoreAVC (gdb reports pUnk->vt as inaccessible memory). I believe this data has already been released (but pUnk not zeroed) by the time this gets called (MemAllocator_Decommit) though I haven't dug into it much. All I know so far is it didn't used to segfault on termination before the patch was applied. I'll try to collect more info, and I realize that as CoreAVC isn't a supported codec, I'm on my own, but I figured I'd report it nonetheless.

Nice, would be hard split the scaling&color conversion and have it also in swscale? (I know it won't be _that_ easy) > The attached patch adds detection for libspe2 to the configure script.

[PATCH] allow highly experimental negative panscan values
by Reimar D?ffinger 28 Jul '07

28 Jul '07

Hello, what do you think about attached patch? It allows to "zoom out" with some vos (gl works almost fine except that for too large values it flips the video, xv crashes or gives errors with too large but works mostly, breaks switching out of fullscreen for gl2, others not tested). Greetings, Reimar Döffinger

[RFC] hack around desync on OSS pause
by Reimar Döffinger 19 Jul '07

19 Jul '07

Hello, what do you think about attached patch? It fixes the massive desync that happens esp. when doing lots of frame stepping with -ao oss. It is a bit hackish though, and in difference to alsa it will still loose some sound during pause and not play any sound while framestepping. Greetings, Reimar Döffinger

[PATCH] disable mediaLib by default and make test Solaris-only
by Derek E. Lewis 13 Jul '07

13 Jul '07

mediaLib has been broken for quite awhile now on Solaris/SPARC in lavc, and will definitely not be fixed before pre8 is released. Whenever a user encodes using lavc they get a 'thick' green-tint in the output file. A similar event takes place when decoding. mediaLib provides no performance gains for x86 -- in reality, it does the opposite. After doing some quick decoding benchmarks[1] between MPlayer binaries /w mediaLib and w/o mediaLib, I calculated that MPlayer is 2.3x faster on Solaris/x86 if one disables mediaLib, which is not the default, now. I've also made mediaLib a Solaris-only test, and updated the ChangeLog to reflect this patch. Thanks, [1] Tests done using `matrixbench_highdivx_ac3.avi' in the testsuite and lavc for decoding. -- Derek E. Lewis dlewis(a)solnetworks.net http://riemann.solnetworks.net/~dlewis
