Hello everybody, after hours of searching on the net I'm quite desperate to find solution for this. I've up & running OGG Theora decoder in DirectShow which ouputs YV12 and YUY2 color models. Now, I want to make a RGB pixel manipulation filter for this output and to process it into video renderer. According to http://msdn.microsoft.com/...

Hello, I have a query regarding using ffmpeg to encode a raw video(yuv sequence) to Raw Theora packets, i.e. some kind of 'elementary bit-stream' without the Ogg container. I am able to use ffmpeg to encode a raw video to Ogg theora bit stream, but i need to obtain a Theora bit stream with Raw Theora packets with no Ogg container heade...

Hello, I have a Theora video deocder library and application compiled using VS-2008 on windows(Intel x86 architecture). I use this setup to decode theora bit streams(*.ogg files). The source code for this decoder library is used from FFMPEG v0.5 source package with some modifications to make it compile on windows-VS-2008 combination. ...
I have this html5 code, with a MP4 for Chrome (working), an OGG for Firefox (failing) and the same ogg via a java applet for Internet Explorer (working): <video width="848" height="480" controls="controls" autoplay="true" > <source src="vernissage_cpal_2009.mp4" type="video/mp4" /> <source src="vernissage_cpal_20...
Hi, I am in process of porting and optimization of the theora video decoder in the ffmpeg-0.5 package to ARM-Cortex-A8 -Neon processor @ 667 MHz. I am looking for some target estimate for frames per second the decoder library alone should achieve after full optimization (C level and Neon assembly / Intrinsics) for 720x480 Progressive co...
Hi folks, I have the following code: <video width="640" height="360" controls id="video-player" poster="/movies/poster.png"> <source src="/movies/640x360.m4v" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> <source src="/movies/640x360.ogv" type='video/ogg; codecs="theora, vorbis"'> </video> I'm using Rails (Mongrel in developm...
I'm trying to make a PHP script that will deliver a given .ogx file based on a seek position (transmited as a parameter to the script). The purpose is to make a HTML5 video player with server-side seeking functions. I have studied the container format a bit and made the .php script to start delivering data from the first instance of the...
Hello! I need merge two files with video (without recompressing video) compressed by theora codec, without sound, to do that i parse each file, find packets inside, change flag 5 bit in packet header to 0 (continue flag) and set for all packet equal serial. This methon works fine, but have some problem with granulepos. Help me please wi...
Hello, I am currently writing a simple Theora video encoder, which uses libogg, libvorbis and libtheora. Currently, I can submit frames to the Theora encoder, and PCM samples to the Vorbis encoder, pass the resulting packets to Ogg streams (one for Theora and one for Vorbis) and get pages out. When the program starts, it flushes the he...
I'm looking for fellow users, who are using Xuggler to produce video encoded with Theora. I've tried a lot of different options to get "good" quality using presets to no avail. I would love to get quality anywhere close to what I can produce with the Miro converter tools defaults. Sadly, the web doesn't seem to have much to say except th...
