编译成 aar

在 src目录下执行：
./tools_webrtc/android/build_aar.py --output "libwebrtc-m88.aar" --build-dir out --arch "armeabi-v7a" "arm64-v8a" --extra-gn-args 'is_debug=false strip_debug_info=true  rtc_use_h264=true ffmpeg_branding="Chrome" proprietary_codecs=true treat_warnings_as_errors=false'

修改third_party/ffmpeg/ffmpeg_generated.gni：

    use_linux_config = is_linux || is_fuchsia
->  use_linux_config = is_linux || is_fuchsia || is_android

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/config.h:

    #define CONFIG_H264_DECODER 0
->  #define CONFIG_H264_DECODER 1

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/libavcodec/parser_list.c

    static const AVCodecParser * const parser_list[] = {
    ...
    &ff_vp9_parser,
+   &ff_h264_parser,
    NULL };

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/libavcodec/codec_list.c

    static const AVCodec * const codec_list[] = {
    ...
    &ff_libopus_decoder,
+   &ff_h264_decoder,
    NULL };

增加H264编解码支持

在sdk/android/api/org/webrtc中增加LibH264Decoder.java、LibH264Encoder.java，格式与原有Decoder、Encoder一致：

LibH264Encoder.java

package org.webrtc;

public class LibH264Decoder extends WrappedNativeVideoDecoder {
  @Override
  public long createNativeVideoDecoder() {
    return nativeCreateDecoder();
  }
  static native long nativeCreateDecoder();
}

LibH264Encoder.java

package org.webrtc;

public class LibH264Encoder extends WrappedNativeVideoEncoder {
  @Override
  public long createNativeVideoEncoder() {
    return nativeCreateEncoder();
  }

  static native long nativeCreateEncoder();

  @Override
  public boolean isHardwareEncoder() {
    return false;
  }
}

在sdk/android/src/jni中添加h264_codec.cc，格式与原有vp8_codec.cc/vp9_codec.cc一致：

#include <jni.h>
#include "modules/video_coding/codecs/h264/include/h264.h"
#include "sdk/android/generated_libH264_jni/LibH264Decoder_jni.h"
#include "sdk/android/generated_libH264_jni/LibH264Encoder_jni.h"
#include "sdk/android/src/jni/jni_helpers.h"

namespace webrtc {
namespace jni {

static jlong JNI_LibH264Encoder_CreateEncoder(JNIEnv* jni) {
  return jlongFromPointer(H264Encoder::Create(cricket::VideoCodec("H264")).release());
}

static jlong JNI_LibH264Decoder_CreateDecoder(JNIEnv* jni) {
  return jlongFromPointer(H264Decoder::Create().release());
}

}  // namespace jni
}  // namespace webrtc

在sdk/android/api/org/webrtc/中修改SoftwareVideoDecoderFactory.java、SoftwareVideoEncoderFactory.java增加对H264的支持

SoftwareVideoDecoderFactory.java

  public VideoDecoder createDecoder(VideoCodecInfo codecType) {
+   if (codecType.getName().equalsIgnoreCase("H264")) {
+     return new LibH264Decoder();
+   }
    ...
    return null;
  }

  static VideoCodecInfo[] supportedCodecs() {
    List<VideoCodecInfo> codecs = new ArrayList<VideoCodecInfo>();
    
+   codecs.add(new VideoCodecInfo("H264", new HashMap<>()));
    codecs.add(new VideoCodecInfo("VP8", new HashMap<>()));
    ...
    return codecs.toArray(new VideoCodecInfo[codecs.size()]);
  }

SoftwareVideoEncoderFactory.java

 public VideoEncoder createEncoder(VideoCodecInfo info) {
+   if(info.name.equalsIgnoreCase("H264")) {
+     return new LibH264Encoder();
    }
    ...
    return null;
  }

  static VideoCodecInfo[] supportedCodecs() {
    List<VideoCodecInfo> codecs = new ArrayList<VideoCodecInfo>();

+   codecs.add(new VideoCodecInfo("H264", new HashMap<>()));
    codecs.add(new VideoCodecInfo("VP8", new HashMap<>()));
    ...
    return codecs.toArray(new VideoCodecInfo[codecs.size()]);
  }

在sdk/android/BUILD.gn中关联上述新加逻辑：

android 编译webrtc 支持H264软编 - housekeeper-software/tech GitHub Wiki

基础版本

参考

编译成 aar

修改third_party/ffmpeg/ffmpeg_generated.gni：

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/config.h:

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/libavcodec/parser_list.c

修改third_party/ffmpeg/chromium/config/Chrome/android/arm64(arm-neon)/libavcodec/codec_list.c

增加H264编解码支持

在sdk/android/api/org/webrtc中增加LibH264Decoder.java、LibH264Encoder.java，格式与原有Decoder、Encoder一致：

LibH264Encoder.java

LibH264Encoder.java

在sdk/android/src/jni中添加h264_codec.cc，格式与原有vp8_codec.cc/vp9_codec.cc一致：

在sdk/android/api/org/webrtc/中修改SoftwareVideoDecoderFactory.java、SoftwareVideoEncoderFactory.java增加对H264的支持

SoftwareVideoDecoderFactory.java

SoftwareVideoEncoderFactory.java

在sdk/android/BUILD.gn中关联上述新加逻辑：

完整的 BUILD.gn(但凡出现 h264的地方基本上都是修改的地方)
