WebChimera不受Linux的正式支持，但是我已在Ubuntu 16.04上使用它，将VLC升级到2.2.4，并在WebChimera.js v0.2.7 Releases(WebChimera.js_electron_1.4.13_x64_linux.zip)中使用了预构建的软件包。
我已经在Ubuntu 16.04和VLC 2.2.2(16.04上的VLC的官方版本)上自己构建了WebChimera。对于某些视频，一切正常，但是对于某些视频，播放时我只能听到音频，并且出现黑屏(无视频输出，但音频还可以)。我不想将我的VLC升级到2.2.4。我该如何解决这个问题？
在 Electron 版v1.6.8上，控制台写入以下错误:
[h264 @ 0x2e3c62ba0880] No start code is found.
[h264 @ 0x2e3c62ba0880] Error splitting the input into NAL units.
在较旧的 Electron 版本(例如v1.4.0或v1.1.0)上，会记录以下错误:
[h264 @ 0x1262f42c8480] no frame!
或者
[h264 @ 0x3f08b31d5000] The maximum value for lowres supported by the decoder is 0

最佳答案
将VLC更新到2.2.4及更高版本解决了我的问题。
关于electron - WebChimera和wcjs没有在Ubuntu 16.04上预构建的视频输出，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44078591/
