similar to: [PATCH] FFmpeg theora encoding

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

(Cross posted to theora-dev@xiph.org and ffmpeg-devel@mplayerhq.hu) I am working towards adding Theora encoding support to libavcodec in FFmpeg. I am doing this by simply calling libtheora from libavcodec. I am at the point where I can execute: "./ffmpeg -v 100 -i test.wmv -f avi -an -vcodec theora -b 1000000 -y test.avi" I get some whirring and an output file written. My calls to

Hi, I am letting myself known incase someone is interested in this or already has ideas on the subject. I would like to add Theora encoding to ffmpeg's libavcodec library. My goal is to add vorbis / theora / ogm output to Handbrake. Doing this at the libavcodec level appears to make the most sense as it would benefit more people. I have already made a small start. I have the configure

I tested the new FFMPEG2THEORA 0.26 and some players. 1. Biggest bug: http://freefile.kristopherw.us/uploads/temp/push5tru.zi7 encodes into http://freefile.kristopherw.us/uploads/temp/push5tru.ogv the problem: it doesn't play well. MPLAYER reacts very badly, reports "invalid frames" and HANGS (known issue ???). But in VLC there is also a problem, less severe:

Hello, hope you can help me. I want to encode a video, which I have exported from Keynote (a program for presentation like MS Power Point) using ffmpeg2theora for html5 web delivery. The result only plays very buggy - frames are dropped, the video hangs and vlc can not output the correct length of the ogv video. Here is the source and the result for download, if you want to reproduce it: the

hi all, I am using Ubuntu 7.04 version. please can anyone tell me what are the files that copy in to a computer when it install. the following are the some of observations i got. After installing the theora it will copy the required files to the following places (default) according to the configure script. libtheora: ................... /usr/local/lib C header files: ..............

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

I try to merge VP3's mmx decoder into theora. http://kyoto.cool.ne.jp/vp3/developers/theora-alpha3-MMXd-src.zip You can see the change by searching the keyword "_UsingMMX_" in all lib folder's file. From VP3???YO vp3@go8.enjoy.ne.jp

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, and thank to you all for this great codec ! I have this bug on Debian Lenny with compiled packages of last svn versions of ffmpeg and libtheora. This seems to append only on the amd64 arch. Here is a valgrind log : pre-barreau at augustins:~/video$ export LD_LIBRARY_PATH=/usr/local/lib pre-barreau at augustins:~/video$ valgrind /home/pub/apps/ffmpeg_dev/ffmpeg_svn/ffmpeg -i

Hi all, streamnik started a new video streaming internet service (IPTV-Stations). We have actually started the "testing" period and would like to encourage some theora/vorbis/ogg developers to test the stream against various players for any problems. if you like, visit: http://www.streamnik.de Actually the page is only in german, however we are working on an international page.

Hey Theorans, Yesterday and today I decided to try out broadcasting a video stream using Theora from my computer's built-in webcam. I was pleasantly surprised to find that, while maintaining a rate of less than 150kbps, the stream was of quite a suitable quality sending 640x480 video at 15 frames per second. For now, this is video only, by the way, I did not include any audio in the stream

Hi, I'm new here - thanks for having me. (Sorry if I'm in the wrong place or a noob.) I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a sequence of bitmaps, and created an OGV file. The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else with it: I tried uploading to YouTube, and the video just comes out really corrupt:

I posted a while back "complaining" about lack of a theora player on the iPhone. Porting the code for libtheora (and libogg/libvorbis) was (relatively) painless, and appears to be working. I'm up against a tougher challenge now... rendering the video! I tried using the brand-new SOC-funded SDL port to iphone to get the "player_example.c" code up and running, but ran into

I'd like to convert my DVD collection to Theora, but discovered that my good old powerbook (1GHz G4) can't keep up with it (tho a 1.2GHz P-III has no trouble with it): it seems to need a tiny bit more than 100% of CPU. I create my video files with Thoggen, at the largest possible size, with a quality setting of 50%. And I play them with VLC. Any hint of what I might want to try to do?

I just finished using my mother's PC which is running Windows XP. I downloaded & installed, or already had installed, the latest versions of VLC Media Player (1.0.5), Media Player Classic - Home Theater (last release was in August 2009), Miro (already installed), Mozilla Firefox (3.6), Google Chrome (latest from website today), Opera (10.50 Alpha, latest build from the website), and

Just trying to debug my theora encoder... just wondering if someone could give me some insight on a few thigns... In the yuv_buffer i'm sending in... i am just setting y_stride = y_width = videoWidth uv_stride = videoWidth/2 y_height = videoHeight uv_height = videoHeight/2 Making the y buffer (width*height) and each of u and v (width*height/4) Am i correct in doing this ? I knwo stride

In the discussion of having a freedom-friendly camcorder or other video device, we discussed the idea of using intra-only Theora video to make post-recording editing a much easier process, allowing things like frame-by-frame editing without the need to decode and reencode the video again, thus incurring loss. I was quite skeptical of the efficiency of intra-only Theora, and I had speculated that

Hi, last week's thread about getting closer to a release fizzled out. The mailing list discussion and the TheoraTodo wiki item suggest the following are required for release: 1. freeze the theora logical bitstream format 2. complete the reference implementation tools 3. stablize the libtheora API 4. complete the documentation I'd like to suggest this as

https://roundup.ffmpeg.org/roundup/ffmpeg/issue1197 I had originally encountered this problem using ffmpeg2theora. I switched to ffmpeg proper in an attempt to identify where the problem was at, and found that the problem persisted. As a result I had thought this was a problem with ffmpeg, but the ffmpeg folks seem to indicate that this is specific to Theora (too much finger pointing I think.) I
