Where to find open source examples of use of x264 (or any other h264 encoding lib) with directshow on windows mobile? (for example to record video from camera in the mobile phone where h264 is not supported by default into h264) ...
Hi, I am trying to exctract the meta data from x264-encoded video files. First priority is to map the IDR-frames structure. The work seams to be harder than expected and I am trying to find command line applications that I can control from my code. Mp4box has an option "-dump-xml" or similar but I can't figure out how it works. Not muc...
The iPhone app I am working on captures images in series within certain user-defined time interval, I am looking for a way to combine these images into H264 encoded videos. I have done some research on Google, it looks like I will have to use something like ffmpeg/mencoder on iPhone? (Also found someone ported ffmpeg to iPhone, ffmpeg4iP...
I have encoded a video to a raw 264 bitstream using x264. JM decoder correctly decode the video. However, when I try to extract the modes and motion vectors of the macroblock by printing out the macroblock info, they print out the wrong values. Have anyone experience these before ? ...
What will be the best way to parse x264 bitstream for extracting motion vectors information? ...
How to obtain the frame difference between the fenc (encoded frame) and fdec of the current frame (decoded) in X.264? ...
I've got an image generator written in C. Now I want to pass those images to x264 to encode them and write it to a file. Every 100th image should be a key frame in order to save the video to disk every 100th frame. The image generator calls onImageGenerated() after each image. I'd appreciate any pointers on how to set up x264 in this...
I'm creating opensource GPL H264 encoding lib/app (based on x264) do I need to pay for the license? ...
Hi Guys, I have a confusion about the timestamp of h264 RTP packet. I know the wall clock rate of video is 90KHz which I defined in the SIP SDP. The frame rate of my encoder is not exactly 30 FPS, it is variable. It varies from 15 FPS to 30 FPS on the fly. So, I cannot use any fixed timestamp. Could any one tell me the timestamp of the...
Hi All, I have just created and iPhone web app, which has some x264 (mp4) video files on it. When I link directly to the file on the iPhone and the user taps the link, the video player is loaded and the video starts playing. Using the app on an Android phone causes the browser to download the video instead of just playing it. Is there ...
I'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree: http:...
Hi All, I am trying to encode video in h.264 that when split with Apples HTTP Live Streaming tools media file segmenter will pass the media file validator I am getting two errors on the split MPEG-TS file WARNING: Media segment contains a video track but does not contain any IDR access unit with a SPS and a PPS. WARNING: 7 samples (17....
I'm trying to compile x264 with mp4 output support. I download the latest version from their git by typing git clone git://git.videolan.org/x264.git When I run ./configure it configures and I'm able to make it. But when i try to configure it with ./configure --enable-mp4-output and then try to make it, it returns a strange error...
When I try to create pipeline that uses H264 to transmit video, I get some enormous delay, up to 10 seconds to transmit video from my machine to... my machine! This is unacceptable for my goals and I'd like to consult StackOverflow over what I (or someone else) do wrong. I took pipelines from gstrtpbin documentation page and slightly mo...
Hello! I'm creating mobile version of YouTube-like website. And i'm going to use Darwin Streaming Server for streaming low-res clips compressed with x264 and NeroAAC and hinted with MP4Box. When i'm playing it with VLC player streaming works fine, as expected. When i'm trying to open URL with my HTC Hero, it switches to player mode, the...

Hi, I'm trying to compile x264 for use in an iPhone application. I can compile with using http://github.com/gabriel/ffmpeg-iphone-build File: build-x264-armv6/7. but only decoding. I want to use encoding too. when I use build-x264-armv6/7,The console show me "mp4 output: no". Does anyone know how to compile x264 which is able to encodin...
I've downloaded the source code and am wading through it --- does anybody know where the QMs for the images and the residuals are stored? ...
so in dll we have x264_param_t structure\object and a function for its setting up x264_param_apply_profile. in C we use such code to set it up x264_param_t param; x264_param_default_preset(¶m, "veryfast", "zerolatency"); param.i_threads = 1; param.i_width = width; param.i_height = height; param.i_fps_num = fps; param.i_fps_den = 1;...
