similar to: usage of --two-pass parameter with ffmpeg2theora?

Hello, I'm using ffmpeg2theora.linux to encode video casts from http://digit.cz For one particular episode 24, I discovered two issues: 1. minor one - at beginnig, software is reporting very big and long result ffmpeg2theora.linux digit24.mp4 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'digit24.mp4': Duration: 00:42:41.04, start: 0.000000, bitrate: 1177 kb/s Stream #0.0(eng):

Hello, Can I achieve with --two-pass better quality for same size or --videoquality 5 is fine and I will not get any improvement? Thank you, Jiri

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

Hello, I need to demux video files created with ffmpeg2theora 0.28+svn18147 I have ogminfo v1.5 and getting this error (ogminfo.c) OGG stream 1 is of an unknown type (bad header?) (ogminfo.c) OGG stream 2 is of an unknown type (bad header?) (ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000) Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

Hi Folks, First, I would like to thank the eople in development who are doing so much to develope these great video and audio tools. I use Ogg Vorbis to store most of my music projects in studio and the results are stunning. Quite frankly, in the audio file reduction game, nothing beats Ogg Vorbis and I can personally say this from my own experience. So a huge thank you to the team. I've

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

I am trying to encode the Sintel documentary AVI from DVD #3 using ffmpeg2theora 0.27 (which is the latest released version). You can download this AVI file from http://www.archive.org/download/Sintel/Sintel_Documentary_by_Ali_Boubred.avi I'm doing this encode on Fedora 13 GNU/Linux on a 64-bit AMD processor. The program encodes the video but I get something that looks like a warning and

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora (one audio an one video) and did not found, how to mux them into one file? Exist a way, how to do two pass encoding? I'm using Ubuntu Fiesty Linux. Thank you, Jiri Navratil

Hello, I'm finishing my preparation to distribute video recording from Software Freedom Day 2010 on a HTML5 page with references to video files I had converted thx to ffmpeg2theora to Ogg file with Theora video and Vorbis audio. I have the video files already converted and I wish to add some metadata to video file (and propably to HTML5 page too?) I'm thinking about year, copyright,

Hi good people, Just to inform: I finally fed FFMpeg2Theora with a .VOB input, and the .OGV output produced played back beautifully in VLC, both audio and video. However, the same output .OGV file gave clicks and pops in the audio when fed through Directshow programs. I played it through Windows Mediaplayer as well as through Winamp, with the same crackles in the audio, and this leads me to

I built ffmpeg2theora from SVN, using libogg 1.1.4, libvorbis 1.2.3 and Thusnelda from SVN. Running ffmpeg2theora --help reports that ffmpeg2theora accepts a range of -2 to 10 for the --audioquality option and a bitrate of 32 to 500 for the --audiobitrate option, but it doesn't appear to actually accept any of the low end numbers. It appears that the lowest acceptable value for

Hi, We build a Voip client with Iaxclient(Jiaxclient+Iaxclient2.1beta1+Theora1.0+libvidcap0.21),when we established video call with resolution 640X480 in both sides,the CPU is consumed about 100%,the workload of Asterisk server is good at that moment.This issue does not exist with the resolution 320X240, the environment is as following, - CPU Interl Celeron 2.66GHz,RAM1GB, - Windows XP

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)

Hello, Thank's to fast replies on this list, I can now encode to Theora from demuxed files. Thank you again. So far, I used Vorbis + H.264 (Mencoder, x264, double pass) in Matroska. To be prepared for switch to Vorbis + Theora in Ogg, I need to learn, how to achieve at least close results in quality / size. First result show me, that with video bitrate = 1000, the Ogg file have doubled size

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

After a liveupgrade and luactivate I can login to the -new- BE. My question is: do I have to luactive the -old- BE again if I want to chose that one from the grub menu or can I just run it if I want to. -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS sxce snv107 ++ + All that''s really worth doing is what we do for others (Lewis Carrol)

Hi, I'm trying to add Title and other metadata to OGV, when encoding with ffmpeg2theora 0.24. Unfortunatelly, mplayer and VLC is not showing any metadata. Shall this work with ffmpeg2theora 0.24? Exist something like vorbiscomment to check / do it with OGG/Vorbig/Theora? Thank you, Jiri

Hi, When an audiopacket is received too late I could interpolate this frame. The problem is that I don't know if it is a true bufferloss or just the last audiopacket of a talkspurt. Now my question is if it's harmfull for the audioquality that at the end of the talkspurt one frame is interpolated? Or would this be almost inpossible to hear since the last audiopacket in the talkspurt
