Qt version: 5.7.1
ffmpeg version: n3.3
Android version: 5.1.1 ( but I've tried on some different devices )
I'm trying to use the Android API MediaCoded that have been supported by ffmpeg
but while I try to open the codec I got "Operation not permitted" all times,
I've tried some changes and I've tried to find examples without not luck.
This is what I'm doing
av_jni_set_java_vm(QAndroidJniEnvironment::javaVM(), NULL);
av_register_all();
avcodec_register_all();
AVCodec *_codec(nullptr);
AVCodecContext *_codecContext(nullptr);
if (_codec == nullptr)
_codec = avcodec_find_decoder_by_name("h264_mediacodec");
if (_codecContext == nullptr)
_codecContext = avcodec_alloc_context3(_codec);
int ret = 0;
if( (ret = avcodec_open2(_codecContext, _codec, NULL)) < 0 ) {
char str[AV_ERROR_MAX_STRING_SIZE];
memset(str, 0, sizeof(str));
av_strerror(ret, str, sizeof(str));
qDebug("avcodec_open2 \"%s\" error[code:%d text:\"%s\"]",_codec->long_name,
ret, str);
}
And I'm getting this output
avcodec_open2 "H.264 Android MediaCodec decoder" error[code:-1 text:"Operation
not permitted"]
What I'm doing wrong?
