Question

Linux正式支持WebChimera，但是我已经在Ubuntu 16.04上使用它，将VLC升级到2.2.4并在WebChimera.js v0.2.7 Releases使用预构建的包fount（WebChimera.js_electron_1.4.13_x64_linux.zip）

我自己在Ubuntu 16.04和VLC 2.2.2（16.04的VLC正式版）上构建了WebChimera。对于某些视频，每件事情都可以，但对于某些视频，我只能在播放时听到音频，并且有黑屏（没有视频输出，但音频没问题）。我不想将我的VLC升级到2.2.4。我该如何解决这个问题？

在电子v1.6.8上，控制台写入此错误：

[h264 @ 0x2e3c62ba0880] No start code is found.
[h264 @ 0x2e3c62ba0880] Error splitting the input into NAL units.

在较旧的电子版本（如v1.4.0或v1.1.0）上，写入此错误：

[h264 @ 0x1262f42c8480] no frame!

或

[h264 @ 0x3f08b31d5000] The maximum value for lowres supported by the decoder is 0
