search for: 45kbps

Hey all, When I run my scripts to manage my ungodly slow school connection, I get messages about the quantum size being small and suggesting a r2q change. What is this all about, and should I do anything? my link is effectively 45kBps and I have it set to limit to 42kBps.

Hello everyone, I'm currently developing an adaptive videoconferencing application based on Ekiga which uses TFRC as a congestion control mechanism to adapt the video encoding rate according to the quality of the network experienced. My goal was to use the open-source Theora codec for video transmission. Unfortunately, it seemed that Theora 1.0 did not properly implement any correct CBR mode.

...mpting to use libtheora and I have been looking through the examples in the distribution Excerpt from encoder_example.c -- case 'V': video_r=rint(atof(optarg)*1000); if(video_r<45000 || video_r>2000000) { fprintf(stderr,"Illegal video bitrate (choose 45kbps through 2000kbps)\n"); exit(1); } video_q=0; break; I assume 'kbps' is Kilobits Per Second (kbit/s) and *theora_info.target_bitrate* is in Bits Per Second. If this is true then shouldn't the argument (optarg) be multiplied by 1024 and not 1000? Or do...

I have to reduce the resolution to 1024x768 to make the image correct. It seems that the limit of the bit rate is too small. Can any body tell me how to make large resolution ogg file. Thank you.

...think Vorbis sounds good with its "quality" settings, I have a few problems when I set the format to constrain the bitrate so it doesn't go any higher than 128KBPS, for example. This problem only occurs with stereo files, not mono. Let's say I set the format to use bitrates up to 45KBPS. Well, the low-pass filter has this problem, the closer the volume gets to 0DB, the lower the cutoff, by 0DB I think it's around 4KHZ cutoff but when the volume gets quiet it sounds like the cutoff is where it should be. The higher I let the bitrate go, the less the lowpass filter acts up, by 8...

Hi again, I was just looking at reviews on vorbis and reading some listening test results when I came across several web sites that were saying something about Vorbis quality -2. From what I read a few programs have Vorbis going down to quality -2 and I even think hydrogen audio forums mentions it in a speech compression topic. Does this quality really exist and has anyone even heard of it? I
