Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

Not able to Receive Exact Data over UDP
20 juin 2016, par Prasanth Kumar ArisettiI am transferring the data over udp using below pipeline,
gst-launch-1.0 videotestsrc ! videoconvert ! x264enc ! mpegtsmux ! rtpmp2tpay ! udpsink host=192.168.1.139 port=8090
And receiving the data by using below pipeline,
gst-launch-1.0 udpsrc port=8090 ! tsdemux ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink
The Problem is,
Until a moment, i am getting the data exactly, but after few seconds,
The whole window is becoming in greem color,
But Sometimes, getting the data correctly, but sometimes, i am getting the green screen. What is the Problem Here ? And how to resolve it ? And Why it is happening like that ?

encode x264(libx264) raw yuv frame data
12 janvier, par Mohamed El-SayedI am trying to encode an MP4 video using raw YUV frames data, but I am not sure how can I fill the plane data (preferably without using other libraries like ffmpeg)



The frame data is already encoded in I420, and does not need conversion.



Here is what I am trying to do :



const char *frameData = /* Raw frame data */;

x264_t *encoder = x264_encoder_open(&param);
x264_picture_t imgInput, imgOutput;
x264_picture_alloc(&imgInput, X264_CSP_I420, width, height);

// how can I fill the struct data of imgInput

x264_nal_t *nals;
int i_nals;
int frameSize = x264_encoder_encode(encoder, &nals, &i_nals, &imgInput, &imgOutput);




The equivalent command line that I have found is :



x264 --output video.mp4 --fps 15 --input-res 1280x800 imgdata_01.raw 




But I could not figure out how the app does it.



Thanks.
