先去下载源码
git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
cd ijkplayer-ios
git checkout -B latest k0.8.8
./init-ios.sh
cd ios
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
下载下来后打开项目报错误
'libavformat/avformat.h' file not found
是因为./compile-ffmpeg.sh all失败
./libavutil/arm/asm.S:50:9: error: unknown directive .arch armv7-a^make: *** [libavcodec/arm/aacpsdsp_neon.o] Error 1
Xcode 已经弱化了对 32 位的支持
打开compile-ffmpeg.sh中删除armv7,
FF_ALL_ARCHS_IOS8_SDK="armv7 arm64 i386 x86_64"
修改成:
FF_ALL_ARCHS_IOS8_SDK="arm64 i386 x86_64"
...
再重新执行:
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
适配rtsp
config文件夹下的module-lite.sh文件
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --disable-protocol=rtp"
改为
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=rtsp"
cd /到config
rm module.sh //删除原来的
ln -s module-lite.sh module.sh //用修改过的替换
找到ijkplayer-ios/ijkmedia/ijkplayer/ff_ffplay.c
修改
static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue *q, AVPacket *pkt, int *serial, int *finished)
{
assert(finished);
if (!ffp->packet_buffering)
return packet_queue_get(q, pkt, 1, serial);
while (1) {
int new_packet = packet_queue_get(q, pkt, 0, serial);
if (new_packet < 0)
return -1;
else if (new_packet == 0) {
if (q->is_buffer_indicator && !*finished)
ffp_toggle_buffering(ffp, 1);
new_packet = packet_queue_get(q, pkt, 1, serial);
if (new_packet < 0)
return -1;
}
if (*finished == *serial) {
av_packet_unref(pkt);
continue;
}
else
break;
}
return 1;
}
成
static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue *q, AVPacket *pkt, int *serial, int finished){
while (1) {
int new_packet = packet_queue_get(q, pkt, 1, serial);
if (new_packet < 0){
new_packet = packet_queue_get(q, pkt, 0, serial);
if(new_packet < 0)
return -1;
}else if (new_packet == 0) {
if (!finished)
ffp_toggle_buffering(ffp, 1);
new_packet = packet_queue_get(q, pkt, 1, serial);
if (new_packet < 0)
return -1;
}
if (finished == *serial) {
av_free_packet(pkt);
continue;
}
else
break;
}
return 1;
}
然后
./init-ios.sh
cd ios./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
打开项目，编译真机和模拟器，获得ijk库
lipo -create 真机地址 模拟器地址 -output 需要打印到的地址
