need help configuring ffmpeg to decode raw AAC with android ndk
24 octobre 2016, par Matt WolfeI’ve got an android app that gets raw AAC bytes from an external device and I want to decode that data but I can’t seem to get the decoder to work, yet ffmpeg seems to work fine for decoding an mp4 file that contains the same audio data (verified with isoviewer). Recently I was able to get this ffmpeg library on android to decode video frames from the same external device but audio won’t seem to work.
Here is the ffmpeg output for the file with the same data :
$ ffmpeg -i Video_2000-01-01_0411.mp4

handler_name : videHere is my ndk code for setting up and decoding the audio :
jint ffmpeg_init(JNIEnv * env, jobject this) {
audioCodec = avcodec_find_decoder(AV_CODEC_ID_AAC);
if (!audioCodec) {
LOGE("audio codec %d not found", AV_CODEC_ID_AAC);
return -1;
}
audioContext = avcodec_alloc_context3(audioCodec);
if (!audioContext) {
LOGE("Could not allocate codec context");
return -1;
}
int openRet = avcodec_open2(audioContext, audioCodec, NULL);
if (openRet < 0) {
LOGE("Could not open codec, error:%d", openRet);
return -1;
}
audioContext->sample_rate = 8000;
audioContext->channel_layout = AV_CH_LAYOUT_MONO;
audioContext->profile = FF_PROFILE_AAC_LOW;
audioContext->bit_rate = 48 * 1024;
audioContext->sample_fmt = AV_SAMPLE_FMT_FLTP;
// unsigned char extradata[] = {0x15, 0x88};
// audioContext->extradata = extradata;
// audioContext->extradata_size = sizeof(extradata);
audioFrame = av_frame_alloc();
if (!audioFrame) {
LOGE("Could not create audio frame");
return -1;
}
}
jint ffmpeg_decodeAudio(JNIEnv *env, jobject this, jbyteArray aacData, jbyteArray output, int offset, int len) {
LOGI("ffmpeg_decodeAudio()");
char errbuf[128];
AVPacket avpkt = {0};
av_init_packet(&avpkt);
LOGI("av_init_packet()");
int error, got_frame;
uint8_t* buffer = (uint8_t *) (*env)->GetByteArrayElements(env, aacData,0);
uint8_t* copy = av_malloc(len);
memcpy(copy, &buffer[offset], len);
av_packet_from_data(&avpkt, copy, len);
if ((error = avcodec_decode_audio4(audioContext, audioFrame, &got_frame, &avpkt)) < 0) {
ffmpeg_log_error(error);
av_free_packet(&avpkt);
return error;
}
if (got_frame) {

(*env)->SetByteArrayRegion(env, output, 0, audioFrame->linesize[0], *audioFrame->extended_data);
}
return 0;
}As you can see I’ve got an init function that opens the decoder and creates the context, these things all work fine, without error. However when I call avcodec_decode_audio4 I get an error :
FFMPEG error : -1094995529, Invalid data found when processing input
I’ve tried all sorts of combinations of AVCodecContext properties. I’m not sure which I need to set for the decoder to do it’s job but from reading online I should just need to set the channel layout and the sample_rate (which I’ve tried by themself). I’ve also tried setting the extradata/extradata_size parameters to that which should match the video settings per : http://wiki.multimedia.cx/index.php?title=MPEG-4_Audio
But no luck.Since the device we’re getting packets from sends aac data that have no sound at the beginning (but are valid packets), I’ve tried to just send those since they definitely should decode correctly.
Here is an example of the initial audio packets that are of silence :

My application doesn’t have direct access to the file though so I need to decode the raw frames/samples as I get them. When I look at the audio track data in isoviewer I can see that the audio track’s first sample is the same data as what I got from the device that contained that file (thus, the external device is just sending me the sample’s raw data). I believe this data can be derived from reading stsz (sample size) box starting at stco (chunk offset) boxes from the mdat box of the file.
Also, isoviewer shows the esds box as having the following :
ESDescriptor{esId=0, streamDependenceFlag=0, URLFlag=0, oCRstreamFlag=0, streamPriority=0, URLLength=0, URLString='null', remoteODFlag=0, dependsOnEsId=0, oCREsId=0, decoderConfigDescriptor=DecoderConfigDescriptor{objectTypeIndication=64, streamType=5, upStream=0, bufferSizeDB=513, maxBitRate=32000, avgBitRate=32000, decoderSpecificInfo=null, audioSpecificInfo=AudioSpecificConfig{configBytes=1588, audioObjectType=2 (AAC LC), samplingFrequencyIndex=11 (8000), samplingFrequency=0, channelConfiguration=1, syncExtensionType=0, frameLengthFlag=0, dependsOnCoreCoder=0, coreCoderDelay=0, extensionFlag=0, layerNr=0, numOfSubFrame=0, layer_length=0, aacSectionDataResilienceFlag=false, aacScalefactorDataResilienceFlag=false, aacSpectralDataResilienceFlag=false, extensionFlag3=0}, configDescriptorDeadBytes=, profileLevelIndicationDescriptors=[[]]}, slConfigDescriptor=SLConfigDescriptor{predefined=2}}And the binary is this :

Compile Shotdetect on CentOS 7

The service needs the Shotdetect command (github , official site).
I could not make it work on CentOS though I followed all steps :

Issues with processing media on windows Azure
23 septembre 2015, par Ahmed MujtabaI have a website built on ASP.NET web forms that works as a media portal for users to upload videos. I’m using ffmpeg encoders to produce video contents to be streamed in the browser. I’m using the web deploy method to publish the site on the Azure server. The website get’s deployed properly however I get following issues in the live site.
-
Video never get’s encoded and published. I get some sort of error.
-
Video get’s published but the process of uploading and encoding the video is way too slow on the web server.
My project solution contains upload.ashx that handles the upload requests and makes the call to encode.ashx which is responsible for the encoding and publishing of the videos. I tried to remotely debug the site but the debugger never get’s to encode.ashx.
I was wondering if these issues can be resolved by having the website deployed with a VM ?
