Hi, I am using libvorbis-1.0.1 and I am trying to debug the example decoder (examples/decoder_example.c) using gdb. I have compiled the source tree for debug and can single step through the program. However i am facing the following problem (which I think is more of C than vorbis) 1. after single steppig I finally arrive at the function shown below (in file lib/info.c) static int

Hi All, I am trying to build an Ogg/Vorbis plugin for RealOne Player through the HelixCommunity source. During runtime, however, I saw an access violation. I did some debugging and narrowed it down to the following function in the Vorbis source.. int vorbis_synthesis(vorbis_block *vb,ogg_packet *op){ vorbis_dsp_state *vd=vb->vd; backend_lookup_state *b=vd->backend_state;

I'm interested in ignoring the audio stream in a theora encoded file. My first attempt was to remove the test for vorbis: /* identify the codec: try theora */ if(!theora_p && theora_decode_header(&ti,&tc,&op)>=0){ /* it is theora */ memcpy(&to,&test,sizeof(test)); theora_p=1; }else if(!vorbis_p &&

I'm trying to write an OS X AudioCodec for Vorbis using libvorbis. I'm confused about the libvorbis dependency on libogg. I thought the vorbis spec didn't require ogg as the container, but the

hi all: i downloaded libtheora1.0.tar.gz from xiph.org, and when i compile it, such error message popped. i tried to run player_example.c under /libtheora_1.0/examples/. error message: ivysummer at ivysummer-desktop:~/??/libtheora-1.0/examples$ gcc -o player player_example.c /tmp/ccpyle3c.o: In function `buffer_data': player_example.c:(.text+0x15): undefined reference to

ok, I'm aware that vo_open cant be used at the same time as other functions such as ogg_sync_wrote, ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout and vorbis_synthesis_headerin. In order to get information from the bitstream i've been using this method because it's fast and doesn't require decoding of the stream. But, i can only retrieve the average bitrate of

I'm working with a streaming Ogg Vorbis system where I'm taking the stream output (from a darkice server) and saving it to hour-long files, then reassembling excerpts from these files (sometimes spanning two or three) into a single file for playback. I've got two problems (well, related to this, but anyway). 1) The "chunk" files I'm saving into have mangled headers. 2)

Hey all, If my understanding is right, there's a serious big in vorbisfile.c, in the routine _fetch_headers(), which will only show up when comment packet spans multiple pages. The code to read the first 3 Vorbis packets ogg_stream_pagein() once, then calls ogg_stream_packetout(). The problem is that ogg_stream_pagein() only adds a single page to the ogg stream state, whereas

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've

What I'd like to do is to copy a part of an Ogg/Vorbis file to a new file, without decoding and re-encoding (say I've got several songs in one long file, and I want to split them into separate files). Sample granularity is not required, packet granularity should do. I'm reading the Ogg documentation. I think I could write some code based on ogg_stream_packet{out,in}. Is this the way

At least the policyd-weight in lenny seems to generate quite different patterns. For example the 'rate' is output multiple times in some situations, the 'check from' is omited sometimes and somehow those log messages have a trailing blank. With those patterns logcheck stays silent again. Signed-off-by: Mathias Krause <minipli at googlemail.com> ---

Hi, ??Forgive my poor English, I'm trying to implement a net phone using vorbis codec, which need realtime encode and decode the stream. The problem is, I use vorbis_analysis_buffer() and vorbis_analysis_wrote() push the PCM data in, then use vorbis_analysis_blockout(&vd, &vb) to output a block, it can't output all the data. It seems that some data which length is constant, must

Okay, how do I drop a changeset/patchset/tag for you folks from SVN? At this point, I have written three examples of how to use the basics of the ogg streaming and decoding in Tremor. I heartily welcome any suggestions, improvements and corrections that you can point out in the code. The examples required me to make some small modifications to the main tremor library. However, the changes

(I've already posted this message month ago, but nobody answered, may be it was not delivered to newsgroup?) Hello, All. I wrote an encoder-decoder based on example from OGG-Vorbis SDK. This encoder can encode a large amount of small WAV-files with equal parameters into one sound archive. Then I decode this sound archive back into large amount of small WAV-files. Theese files are

Hi! This little patch turns bitwise.c's mask[] lookup table into a bit-twiddling macro (which avoids the <<32 case without branching). This spares the size of the 132-byte lookup table (and then a bit more, curiously). While I expected this to generally be faster (because it uses a few more instructions in place of a table lookup), it's actually slightly slower than the LUT, in a

Hi, I'm experiencing a serious problem when trying to replace libvorbis with tremor (from svn): premitting that I don't want to use the ov_* functions, calling vorbis_synthesis_headerin() on the 3 initial packets works with libvorbis but immediately fails with tremor. At first sight it seems that the function in tremor either receives a leading \n before every header (that

Hi, Given CVE-2018-5146, I wanted to update the tremor package we have in Buildroot (an embedded Linux build system), and I noticed an inconsistency between the tremor git and svn repos. We are currently using r19427 from svn, but the fix for CVE-2018-5146 was only added to git, so I wanted to move to that. Comparing the two repos I noticed that r19427 is missing from the git repo. r19427 is:

Jan, Here's a hacky patch to add a few commandline options for setting comment header fields in ffmpeg2theora. It's a bit big because I virtualized the global info struct in theorautils.c. In retrospect that probably wasn't necessary, but I think it's cleaner anyway. I didn't test it because I couldn't compile ffmpeg2theora, but modulo bugs it should support
