Error decoding an mp3 stream
by Louis Latreille 15 Mar '14

15 Mar '14

Hello everyone, I have an issue with the mad_decoder. I am currently developing a media server using live555 to stream the data, and libmad to decode the stream received. Currently, I am able to receive the stream perfectly into a file, and it is fully playable through a player (i.e. windows media player). Though, I want to play it with my own program, so I need to decode the stream received. I tried including the minimad test program into my projet with live555, but I am getting the error : decoding error 0x0101 (lost synchronization) at byte offset 0. Here is the function where the mad_decoder is called: void SoundSink::afterGettingFrame(unsigned frameSize, unsigned numTruncatedBytes, struct timeval presentationTime){ if (numTruncatedBytes > 0) { envir() << "FileSink::afterGettingFrame(): The input frame data was too large for our buffer size (" << fBufferSize << "). " << numTruncatedBytes << " bytes of trailing data was dropped! Correct this by increasing the \"bufferSize\" parameter in the \"createNew()\" call to at least " << fBufferSize + numTruncatedBytes << "\n"; } addData(fBuffer, frameSize, presentationTime); if (fOutFid == NULL || fflush(fOutFid) == EOF) { // The output file has closed. Handle this the same way as if the input source had closed: if (fSource != NULL) fSource->stopGettingFrames(); onSourceClosure(); return; } if (fPerFrameFileNameBuffer != NULL) { if (fOutFid != NULL) { fclose(fOutFid); fOutFid = NULL; } } decode((const unsigned char *)"test.mp3", frameSize); //mad_decoder continuePlaying();} In this function I give the decode function (same as in minimad.c) the mp3 file that receives the stream, and the frameSize given by live555 API, which is usually at 1045. static int decode(unsigned char const *start, unsigned long length){ struct buffer buffer; struct mad_decoder decoder; int result; /* initialize our private message structure */ buffer.start = start; buffer.length = length; /* configure input, output, and error functions */ mad_decoder_init(&decoder, &buffer, input, 0 /* header */, 0 /* filter */, output, error, 0 /* message */); /* start decoding */ result = mad_decoder_run(&decoder, MAD_DECODER_MODE_SYNC); /* release the decoder */ mad_decoder_finish(&decoder); return result;} The mad_decoder goes directly into the error function, and outputs nothing due to the error 0x0101 Any help would be greatly useful, Louis

libid3tag: parsing UTF16 in STRINGLIST can result in infinite loop
by Tomáš Nechutný 16 Feb '14

16 Feb '14

Hello. The loop that parses strings from STRINGLIST in field.c on line 294 depends only on length parameter and on function id3_utf16_deserialize() to move the pointer *ptr by length or more in case of UTF16. However, in several files with UTF16 ID3 tags on my PC the *ptr pointer was moved by one byte less. Following calls of id3_utf16_deserialize() didn't move pointer at all so the loop would continue forever or until field->stringlist.strings filled whole memory. I'm not sure if it's fault of invalid ID3 tags but the library should certainly recover from it. Because the last byte is always string terminator I fixed it with horrible hack I attached. I have no idea if it's correct but it avoided the infinite loop so far. I'd love to privately send you test C source and test file with ID3 tags if you're interested. I'm sorry for my dirty half-analysis. I already gave up on MPD which was the only reason why I was debugging this problem.

libid3tag Windows DLL source package available
by Chris Korda 04 Aug '13

04 Aug '13

I made a version of libid3tag that builds a Windows DLL instead of a static library, using reasonably modern tools. My package includes Visual Studio 2008 project files suitable for building both 32-bit and 64-bit targets. The DLL exports only a subset of the library's functions, but this is easily changed by editing libid3tag.def. The C source files are identical to the original 0.15.1b distribution, except for a single one-line change to id3tag.h: an id3_free function was added. DLLs should free any memory they allocate, and if these allocations are directly exposed to the user, the DLL should provide a method for freeing them, so that the freeing can be done by the DLL's heap manager, which may differ from the application's. In a DLL version of libid3tag, strings allocated by functions such as id3_ucs4_latin1duplicate MUST be freed via id3_free instead of free, otherwise the heap will likely be corrupted, potentially crashing the application. The source package is available here: http://sourceforge.net/projects/waveshop/files/tools/libid3tag/ Best regards, Chris Korda http://waveshop.sourceforge.net/

Problems compiling libmad-0.15.1b on ARM CortexA9
by Drasko DRASKOVIC 12 Jul '13

12 Jul '13

HI all, I am trying to compile libmad-0.15.1b on Wandboard with Freescale's i.MX6 Solo processor (ARM Cortex-A9) running Ubuntu Precise LTS.

How to "build" libmad-devel
by Ajay Garg 03 Apr '12

03 Apr '12

Hi all. I have been wanting to get a audacity build, which could provide "Import Audio" feature, on my armv7l-based Fedora 14 machine. I have already asked the audacity-devel guys; it was concluded that audacity needs to be build with "--with-libmad" option; however, on my armv7l machine, I do not have any "libmad-devel" installed, nor can it be found in the "yum" repositories. So, could anyone please point me to the source-code for "libmad-devel", so that I may compile myself? (I have already found the source for "libmad", but not for "libmad-devel"). I will be really grateful. Thanks and Regards, Ajay

Resuming decoding after {STOP || BREAK}
by joseph Dobson 11 Sep '11

11 Sep '11

Hi I am trying to use the MAD library to decode mp3 files for a programming I am working on, the problem is the produced outputs are very large. So my aim was to decode X number of frames, the break until there are spaces for my by resuming the decoding. However this isn't working as I hoped. Currently, I am populating the output buffer, in the high level API, and when it is full then I break (and I have tried stop too) however If I want to resume by calling the decode_run (again) then it never get back to resuming the decoding. So I was inquiring as it whether there was a 'best practice' way of doing this with MAD, of course I could always block the decoder thread when the buffer is full. But I am not sure that is the best way. Thank You
