similar to: ffmpeg2theora conveter problem

Hi, we are using ffmpeg2theora as encoder for a new project. We are finding problems during the conversion step with different type of input compression but, for now, in AVI container. In many case an error generated by ffmpeg lib produce a stop in theora lib (we suppose) Here an example: D:\tmp\ffmpeg>ffmpeg -i f:\vi1.avi vo1.avi ffmpeg version 0.4.9-pre1, build 4743, Copyright (c)

I wish to transcode an AVI from 29fps to 15fps theora. I have tried many combinations. The nearest I have so far is to: 1) ffmpeg -i input.avi -f avi -vcodec rawvideo -acodec pcm_s16le -r 15 -ar 22050 -ac 1 intermediate.avi then 2) ./ffmpeg2theora-0.15.linux.bin -f avi -c1 -H 22050 -o out.ogg intermediate.avi This gives me an output I want, however, the intermediate uncompressed stage

When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds. Here is ffmpeg2theora output: $ ffmpeg2theora --optimize --inputfps 25 -F 25 2002-05-23\ Juho\

Has anyone noticed this? I have a video made with Final Cut Pro, which I convert to .mov via Compressor. This .mov file plays back fine in Quicktime. But when I then use ffmpeg2theora to convert to ogv, the video seems to play back too fast compared to the audio (I'm using VLC 1.0.2, the latest I believe, to play back the ogv file, and I also have an app that uses the recently

Here's another problem I have with the 0.24 version of ffmpeg2theora. When I try to convert a h264 file to theora...

Hi Jan, all I am trying to generate a video introduction with a fade-in / fade-out effect. To do this with ffmpeg2theora only, I generated a list of PNG images: img001.png, img002.png... img299.png The ffmpeg2theora man page says: Encode a series of images: ffmpeg2theora frame%06d.png -o output.ogv That's exactly what I tried with the latest 0.24 release of ffmpeg2theora:

I recorded a television show using my HDHomeRun. The resulting file contains MPEG-2 video and AC3 audio.

I've been encoding with ffmpeg.exe. Due to the muxing issue, I tried ffmpeg2theora, but I ran into some issues 1. it fails on 1080p content. 1920x1080. 1920x800 is okay. 2. I have raw yuv. in ffmpeg I use -s 1920x1080 to specify the source size. ffmpeg2theora doesnt seem to have a way to accept width/height for the raw yuv (420). So I need to do an additional step of muxing it into a

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 again ! Thanks for the info on updating the config.site file which I have done. I have also added -lm in the Makeconf manually because this is needed explicitly for DEC cc.
