用树莓派看电影，加载srt中文字幕时老是闪退并报错，

omxplayer.bin: SubtitleRenderer.cpp:133: SubtitleRenderer::load_glyph(SubtitleRenderer::InternalChar)::: Assertion `!vgGetError()' failed.
/usr/bin/omxplayer: 行 67:  1039 已放弃               LD_LIBRARY_PATH="$OMXPLAYER_LIBS${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}" $OMXPLAYER_BIN "$@"

老婆大人很不满，说干嘛要用你这破玩意儿。

找到一个解决方案(未验证)，先搁这

在/boot/config.txt里加一行 gpu_mem=128，加大GPU缓存
