</listviewitem>I really do not understand in the slightest what is causing all these errors, and why the video file won’t play ?
If anyone is able to help I will highly highly appreciate it !I am using Genymotion Emulator - Google Nexus 4 - API 21
Thank you very much !

no sound when streaming mkv video to html 5 video player via node js
8 septembre 2013, par TristanI have been playing around with building a simple html 5 media server for all my mkv files since I discovered chrome can play them when just dragging and dropping the file into a new tab !
So I actually have something up and going and I am able to stream the mkv files through a nodejs sever to a simple html 5 video player, the only problem is there is no sound and the volume icon in the controls is crossed and greyed out !
Now I realise that mkv files can have multiple audio streams within and this is probably my issue, that the video player doesn't know which one to use or is missing it for some reason.
I have avoided using ffmpeg for the time being as I wanted to stream the videos without any transcoding (and without using express as shown in the fluent-ffmpeg stream example).
See below for the code I use to stream the video :
cFs.exists(sFileName, function(bExists){
if (bExists)
{
var cFile = null;
var cStat = cFs.statSync(sFileName);
if (cRequest.headers['range'])
{
var aParts = cRequest.headers['range'].replace(/bytes=/, "").split("-");
var nStart = parseInt(aParts[0], 10);
var nEnd = aParts[1] ? parseInt(aParts[1], 10) : cStat.size - 1;
var nChunkSize = (nEnd - nStart) + 1;
cFile = cFs.createReadStream(sFileName, {start: nStart, end: nEnd});
cResponse.writeHead(206, {
"Content-Type": "video/x-matroska",
"Content-Range": "bytes " + nStart + "-" + nEnd + "/" + cStat.size,
"Accept-Ranges": "bytes",
"Content-Length": nChunkSize
});
cFile.pipe(cResponse);
cRequest.on('close', function(){
cFile.destroy();
});
}
else
{
cResponse.writeHead(200, {
"Content-Type": "video/x-matroska",
"Content-Length": cStat.size
});
cFile = cFs.createReadStream(sFileName);
cFile.pipe(cResponse);
}
cRequest.on('close', function(){
if (cFile)
{
cFile.destroy();
}
});
/*new ffmpeg({
source: sFileName
}).toFormat('webm').writeToStream(cResponse, function(){
console.log(arguments);
});*/
}
else
{
cResponse.writeHead(404, {
"Content-Type": "text/plain"
});
cResponse.write("404 Not Found\n");
cResponse.end();
}
});if you could help me sort out the sound for the code above or can provide a fluent-ffmpeg solution without using express and retaining as much image quality as possible that would be great !

Convert .m4a to PCM using libavcodec
17 décembre 2013, par gmcc051I'm trying to convert a .m4a file to raw PCM file so that I can play it back in Audacity.
According to the AVCodecContext it is a 44100 Hz track using the sample format AV_SAMPLE_FMT_FLTP which, to my understanding, when decodeded using avcodec_decode_audio4, I should get two arrays of floating point values (one for each channel).
I'm unsure of the significance of the AVCodecContext's bits_per_coded_sample = 16
Unfortunately Audacity plays the result back as if I have the original track is mixed in with some white noise.
Here is some sample code of what I've been done. Note that I've also added a case for a track that uses signed 16bit non-interleaved data (sample_format = AC_SAMPLE_FMT_S16P), which Audacity plays back fine.
int AudioDecoder::decode(std::string path)
{
const char* input_filename=path.c_str();
av_register_all();
AVFormatContext* container=avformat_alloc_context();
if(avformat_open_input(&container,input_filename,NULL,NULL)<0){
printf("Could not open file");
}
if(avformat_find_stream_info(container, NULL)<0){
printf("Could not find file info");
}
av_dump_format(container,0,input_filename,false);
int stream_id=-1;
int i;
for(i=0;inb_streams;i++){
if(container->streams[i]->codec->codec_type==AVMEDIA_TYPE_AUDIO){
stream_id=i;
break;
}
}
if(stream_id==-1){
printf("Could not find Audio Stream");
}
AVDictionary *metadata=container->metadata;
AVCodecContext *ctx=container->streams[stream_id]->codec;
AVCodec *codec=avcodec_find_decoder(ctx->codec_id);
if(codec==NULL){
printf("cannot find codec!");
}
if(avcodec_open2(ctx,codec,NULL)<0){
printf("Codec cannot be found");
}
AVSampleFormat sfmt = ctx->sample_fmt;
AVPacket packet;
av_init_packet(&packet);
AVFrame *frame = avcodec_alloc_frame();
int buffer_size = AVCODEC_MAX_AUDIO_FRAME_SIZE+ FF_INPUT_BUFFER_PADDING_SIZE;;
uint8_t buffer[buffer_size];
packet.data=buffer;
packet.size =buffer_size;
FILE *outfile = fopen("test.raw", "wb");
int len;
int frameFinished=0;
while(av_read_frame(container,&packet) >= 0)
{
if(packet.stream_index==stream_id)
{
//printf("Audio Frame read \n");
int len=avcodec_decode_audio4(ctx, frame, &frameFinished, &packet);
if(frameFinished)
{
if (sfmt==AV_SAMPLE_FMT_S16P)
{ // Audacity: 16bit PCM little endian stereo
int16_t* ptr_l = (int16_t*)frame->extended_data[0];
int16_t* ptr_r = (int16_t*)frame->extended_data[1];
for (int i=0; inb_samples; i++)
{
fwrite(ptr_l++, sizeof(int16_t), 1, outfile);
fwrite(ptr_r++, sizeof(int16_t), 1, outfile);
}
}
else if (sfmt==AV_SAMPLE_FMT_FLTP)
{ //Audacity: big endian 32bit stereo start offset 7 (but has noise)
float* ptr_l = (float*)frame->extended_data[0];
float* ptr_r = (float*)frame->extended_data[1];
for (int i=0; inb_samples; i++)
{
fwrite(ptr_l++, sizeof(float), 1, outfile);
fwrite(ptr_r++, sizeof(float), 1, outfile);
}
}
}
}
}
fclose(outfile);
av_close_input_file(container);
return 0;}
I'm hoping I've just done a naive conversion (most/less significant bit issues), but at present I've been unable to figure it out. Note that Audacity can only import RAW float data if its 32bit or 64 bit float (big or little endian).
Thanks for any insight.
