Hi all. I'm Mat & I'm new :) I'm testing libtheora + libogg perhaps for a commercial product. I started watching encoder_example.c ... I simplified it for testing it easier. It seems ok to me but I have no experience with theora so I would like to know if my code is correct. I tried to debug it with Valgrind and I found 4 possible memory leaks... but I think they can be

if(state==-1){ /* initialize the double frame buffer */ yuvframe[0]=malloc(video_x*video_y*3/2); yuvframe[1]=malloc(video_x*video_y*3/2); /* clear initial frame as it may be larger than actual video data */ /* fill Y plane with 0x10 and UV planes with 0X80, for black data */ memset(yuvframe[0],0x10,video_x*video_y); memset(yuvframe[0]+video_x*video_y,0x80,video_x*video_y/2);

Hi, ffmpeg2theora currently assumes that the first frame in the input file also corresponds to the first audio sample in the input file, which might not be true for many file formats. I have especially bad problems with MPEG-TS streams that I recorded via DVB-T (sync off by 0.5 seconds etc.). Encoding chapter-ranges from DVD might yield similar problems. The attached patch fixes that, using

Hi, the attached patch (against current SVN) adds three new options to ffmpeg2theora: --keyint (set keyframe interval) --smoothness (set the theora_info::sharpness encoding parameter) and --noautosync (disable the new frame dropping/duplicating code). It also fixes a bug with the processing of --cropright that sometimes segfaulted. The sync adjustment code is now tuned to be more reliable. BTW

Updated again... theora works and seeks properly (not to keyframe) in WMP 9 and 10. You can encode from a bunch of onew input types like RGB32, RGB24, IYUV etc. And fixed a bug that was stopping the filters being used in a activeX control in an IE browser. www.illiminable.com/ogg/ Enjoy, Zen.

After posting my previous mail, I realized that i should instead post a patch against HEAD. This is because v0.12 was released while I was also changing ffmpeg2theora.c from v0.11. So please use this patch instead and apply it to version at http://svn.xiph.org/trunk/ffmpeg2theora Nilesh Bansal http://www.cse.iitb.ac.in/nilesh/ -------------- next part -------------- Index: ffmpeg2theora.c

Hi! Some background: I am trying to create an application that would encode video taken by USB camera using Theora and then send it to the client. I have almost succeeded, but I have one problem. When I grab video frames from the camera and encode them they form 4KB OGG pages, then I send them over TCP/IP to the client application. Since I want to achieve as small latency as possible I

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
