Hi there, I'm using mplayer-1.0_rc2_p20090731 on gentoo linux 32bit x86. Lately I've been trying to optimize mplayer video output, since the system it is running on is quite low-end. When playing back 720p H264 material with ASS subtitle rendering the CPU sometimes reaches 100% utilization which results in skipping and AV-sync loses. I did a few searches and ended up switching the video output module from xv to gl, and then tweaking the settings. The GPU is a integrated Intel i915 chip, but with recent mesa git master the use of GL output really boosts the performance (going down from the mentioned 100% utilization to around 60%). However I noticed some strange error/warning message that appears when using -ass and switching from xv to gl. Here is a log when playing back a subtitled file with normal xv output and -ass: http://pastebin.com/m7928bf22 No abnormal messages concerning ASS rendering can be found. Also this output can be found in the log: [ass] Exporting mp_image_t, 1280x720x12bpp YUV planar, 1382400 bytes (this seems to be the subtitle overlay) Now, here is what happens when switching to gl output: http://pastebin.com/m398faf87 Notice that the "Exporting mp_image_t" line from ass is gone. Also notice these two new lines that seem to indicate a problem: Couldn't open video filter 'ass'. ASS: cannot add video filter The funny thing is that even though these lines appear the subtitle rendering works fine and according to the looks of the subs the ASS engine is actually active. Now, here is my question: Why do these messages appear in the first place? Are they simply wrong and the ass filter gets inserted into the playback chain anyway OR is there really a problem that can't just be seen from looking at the video output alone?
