avcodec_open2() error -542398533: Could not open video codec.

[zhangyu007]

MainActivity.java

Hello, I have a question to ask. MainActivity.java is implemented based on the JavaCV library, with version number 1.5.12.

The Gradle code is as follows:

The OpenCV FrameGrabber method calls the camera of an Android phone and captures frame data, which is then passed to the FFmpeg FrameRecorder method and streamed via rtmp. However, an error occurs during runtime: avcodec_open2() error -542398533: Could not open video codec.

The specific log content is as follows:

Please make sure that FFmpegLogCallback.set() has been called.

@tmm1 Looks like a problem with MediaCodec. Any ideas what's going wrong?

[zhangyu007]

@saudet I modified the encoding and was able to push the stream to rtmp normally, but the logs showed some errors. The streaming screen was gray with no color, and the bottom was empty. my phone is android 9.
