And the problem https://github.com/lvgl/lv_drivers/pull/242 still exist. (I haven't found the reason so far.) > you can use `weston --use-pixman` to test on you machine. Thanks @WallaceIT

Recently, I was studying the implementation of `weston-terminal`. It need some time. I think we can find a good solution from it. The code is located in `weston/clients/terminal.c` in [weston](https://gitlab.freedesktop.org/wayland/weston)

May be you can try use `Poco::Message` and try: ```cpp Poco::Message message(module, msg, priority, fileName.c_str(), line); message.setTid(Poco::Thread::currentOsTid()); ``` The thread number is not automatically obtained.

这个提交只是草案，不能运行；只适配了 mov write, mov read 、fmp4 write、 read 都还没有实现完整的替换, 而且其他替换部分逻辑没有严谨地检查,更多的是伪代码的方案设计. 使用 `mov_sample_t` 这种方式暴露内存分配的方式, 调用者如果使用双内存缓冲区作为 cache, 文件缓存作为 store; 应该是会比较好解决内存增长的问题. > 我看了一下代码, `mov_sample_t` 的空间连续性相当得高; 使用双内存缓冲区+文件缓存的方式应该是不会引起文件和内存的频繁交换的; 此外, `mov_blocks_t` 也可以使用 `realloc` 这种现在 media-server 的方式进行实现.

同时 mp4 这种文件比较怕断电，把这部分的内存管理交给调用方，还可以做到断电恢复的效果. > fmp4 确实有这些特性，或者用流式 ts 进行存储；不过很多客户都还在用 win7， fmp4 的兼容性不太好，比如 win 自带播放器就不能进行定位跳转, 所以我还是想尽力尝试 mp4.

感谢; 我可以修改, 我可以改完提交一个 draft 吗

Base on 10.0.2 branch of `weston`, just change the code as follow:  When use cpu to render, the log is shown below:  When use gpu to render, the...

Yes, that's what I want to say.Thanks.

@kisvegabor So far, I haven't found a more appropriate solution. I think `https://github.com/lvgl/lv_drivers/pull/250` may solve this problem. Should we convert these merge to issue for now? > I will still...
