similar to: Missing audio when converting PCM to Ogg

Hello, I am using the Ogg Vorbis library to encode PCM data into ogg format. The conversion seems to work fine with the exception that the last little bit of audio appears cut off in each converted stream. I am essentially following the example from here: http://svn.xiph.org/trunk/vorbis/examples/encoder_example.c When I added a "Sleep(5)" between writing the ogg data to file, and

Hi, I'm a highschool student, I'm looking for information about converting Wave file (*.wav) into Ogg file (*.ogg) and i found encoder_example.c inside libvorbis's example directory. I try to compile it using Microsoft Visual C++ 6.0 ,but it goes error like this : --------------------Configuration: encoder_example - Win32 Debug-------------------- Linking... encoder_example.obj :

Hi Developers, I have a 16-bit PCM data buffer, I want to write that to ogg file. Could you help me to understand how to write pcm data to the ogg? Thanks in advance.

Hi, I'm switching from the mainstream theora trunk to the exp one and I encounter a problem with the encoder. Every video I encode are played like a 'mosaic', I do not know how to say that. The picture is just a bunch of coloured pixels. During the encoding process the video stream is defined like that: File stream.yuv is 320x240 15.00 fps 420 video. Why 420 ? Why not YUV like for

As was briefly discussed on IRC, ffmpeg and mplayer currently output two somewhat incompatible YUV4MPEG streams. This meant that encoder_example could take input from mplayer, but not ffmpeg or movtoy4m (a QuickTime->Y4M tool). This is a patch that fixes this issue and should allow encoder_example to take input from either format: diff -urd xiph-cvs/theora/examples/encoder_example.c

Hello, I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and msys and it fails to build the encoder_example.c example program. There are multiple declarations of the function 'rint'. The source file created its own version of the function that rounds AWAY from zero. MinGW-W64 has its own version of the 'rint' function, which does not round away from zero.

I have encoded successfully a YUV stream by using the encoder_example. Can We encode a row stream (get from a web cam) by using encoder_example. If we can not, is there any other way to encode a row stream by using theora codec. -- Nuwan Millawitiya -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all I have the raw out put of a video camera in following format: mjpegb, yuvj422p, 1920x1080, 24.00 fps(r). I cannot directly convert this raw footage to Theora due to the YUV4MPEG2 only restriction of the encoder_example. Isn't it better to support other raw formats in encoder_example, such as what I have, mjpegb, yuvj422p? I presume even if I convert the mjpegb, yuvj422p to

(Theora/Vorbis) available. Message-ID: <410011E4.2040904@hut.fi> Hello, I noticed that it's quite difficult currently to create Ogg format files (Ogg Theora for video and Ogg Vorbis for audio). There's only the encoder_example-program, which is included in the libtheora source packages, but seemingly not in any libtheora/libtheora-devel packages that are around the web for e.g.

Hello. I'm trying to encode an Ogg Theora file from an unencrypted dvd using mplayer and encoder_example. I set up named pipes stream.wav and stream.yuv. I then run: mplayer -ao pcm -aofile stream.wav -vo null /dev/dvd & mplayer -vo yuv4mpeg -ao null -nosound /dev/dvd & encoder_example -v1 -a 1 stream.wav stream.yuv > lec1.ogg but I get the following error: File stream.wav is

My first guess about the problem would be that the programs want to process the stuff in a different order, e.g. mplayer wants to output some sound before anymore video and encoder_example wants to receive some video before anymore sound. This could easily depend on the order of stuff in the file mplayer is reading. I guess something similar could happen for opening the pipes as well. The

Hello, When I compile either oggenc or encoder_example with static libraries, they work fine, but when I try them with the dynamic libraries, I get an access violation in vorbisenc.dll with both oggenc and encoder_example. Can anyone on win32 confirm this? It's strange because vorbisfile.dll *does* work with vorbisfile_example, and the configuration for vorbisfile.dll is exactly the same

Hello, I'd like to know in detail how does the creation of VQ and Huffman codebooks work in Vorbis. I've used the source code from *encoder_example* as guide, but the only reference I've found is the function *_make_words *inside * vorbis_book_init_encode*, which creates the Huffman tree if I'm not wrong. So I have two doubts. The first is that, for creating the Huffman tree (and

Hi, Can we encode a normal stream in to black & white video using exsisting encoder_example in theora_beta2. Is it required to change encoder_example file to do that? So please guide to do that. Thanks... -- ___ -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I'm new to the list, so if this is an FAQ, please point me to the relevant docs. I'm playing with Theora, to see what kind of quality I can expect (I realise its not for production use yet). I've download the source from CVS, and got it to build, with the example encoder and player. While trying to find something to serve as a good source of input, I decided I'd use a

Hi, I sent the message below a couple of months ago but I got no reply. Now that there's more activity perhaps someone could kindly provide me some guidance. Theora is great and the developers are doing a wonderful job, so I'd like to implement the codec in a way which does it justice... Original post: I wrote a plugin to enable LiVES (a video editor) to encode theora/vorbis/ogg files.

hi all, i tried to encode a .yuv file with the encoder_example.c but it give an error message as follows ./encoder_example -v 1 file_1.yuv > file_1.ogg Input file file_1.yuv is neither a WAV nor YUV4MPEG2 file. so the error message is understandable for anyone. when this file is play with mplayer it shows as follow

i have configuered and built libtheora with --enable-encoder but when i make install, encoder_example is not installed. why not? the object file and script are created in the examples subdir, they are just not installed... thanks for your help -------------- next part -------------- An HTML attachment was scrubbed...

I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the
