Taking a look ahead at your QT (OSX version) work, you have Theora Encoding and Decoding on the list. This could be very beneficial as many times the only way to get a constant frame-rate out of QT is to export (and for DV video recorded in QT, this can be a large issue). Another major issue is that the video coming from DV (at least the sources I have used) is almost always

For last few days I was trying to learn ffmpeg and libtheora API. In the process, I have modified ffmpeg2theora code to include support for start time and end time. ffmpeg2theora -s 60 -e 130 file.avi will produce file.ogg which will be from 60th to 130th second of input file (something like -ss and -endpos in mencoder). This is a useful feature for someone who wants to cut a part of video

dv file from minidv camera - interlaced. small dv created by imported jpeg images - not interlaced. seems that when I use ffmpeg2theora with deinterlace switch and reduce size, it works. But when the only reduction I am doing is to width (720x480 -> 640x480) the encoder ignores the naturally interlaced bit and uses the last de-interlaced frame. Since the small bit made from jpegs is a dv

...form a full picture. DVD playing software typically works by generating a progressive video stream by combining two consecutive (first and second) fields to produce a full progressive frame. For the purpose of displaying true interlaced video (e.g. DVD) to an interlaced television, without using deinterlacing, the full video frames need to be written to the linear video buffer during the retrace after the second frame is drawn, so that both fields are ready to be output in correct order to the display. The current proprietary drivers from nVidia synchronise buffer updates to the retrace after each sing...

Is there any way to get better encoding speed out of ffmpeg2theora? eg: <snip> Duration: 00:57:04.92, <snip> ET: 02:06:24 here is the command: ffmpeg2theora --soft-target -V303 -v4 -F25 -K25 --croptop 8 --cropleft 2 --cropright 2 -x360 -y288 --deinterlace --aspect 4:3 -H24000 -A56 --optimize "<filename.mpg>" also the bitrate, 300kbits == 297kb (3 kbit less)

Theora-devs: I am in seek of a theora (but possibly vorbis/ogg/ffmpeg) dev to optimize the encoding in a realtime software product. We do live encoding and transcode into ogg/theora/vorbis at various resolutions and frame rates. The higher resolutions cannot process in realtime and we are pushing the boundaries of hardware (cpu) encoding with the existing theora/ffmpeg. Right now we have to

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

Hi, Intel has recently open sourced otion compensation code (XvMC) for their i915/i945 integrated graphics chips. See: http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blob;hb=xvmc-i915;f=src/xvmc/I915XvMC.c XvMC API was intended for MPEG{2,4} class of codecs - so it can not be used for Theora as-is. However, could at least some parts of it such as hardware accelerated

I follow the download steps and did everything, but when I clicked the download/install link, it gives me pop-up error: "cannot find 'wine' " My brother also has ubuntu and he gets the same error, please help :( thanks

libshout 2.2 has just been released. It's a fairly minor update: * Speex support (this is why it's 2.2 instead of 2.1.1) * Theora timing fix * Double-free bug, response parser bug on failed login fixed. It's at http://www.icecast.org/download.php

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
