Display YUV420P video using OpenGLES on iPhone
25 décembre 2014, par user3487978I am writing an app displaying YUV420p video using ffmpeg library on iPhone, every thing works fine, but the OpenGL color is a little strange, see picture, the bellow image is displaying using AVPicture in RGB format, above is using AVPicture in YUV format.
any ideas ?my shader
varying highp vec2 varTexcoord;
uniform sampler2D SamplerY;
uniform sampler2D SamplerUV;
void main (void)
{
mediump vec3 yuv;
lowp vec3 rgb;
yuv.x = texture2D(SamplerY, varTexcoord).r;
yuv.yz = texture2D(SamplerUV, varTexcoord).rg - vec2(0.5, 0.5);
// Using BT.709 which is the standard for HDTV
rgb = mat3( 1, 1, 1,
0, -.18732, 1.8556,
1.57481, -.46813, 0) * yuv;
gl_FragColor = vec4(rgb,1.0);

Calling ffmpeg from php
7 juillet 2013, par v3gaI need to run ffmpeg from a php script. The ffmpeg wiki page on the same topic (http://ffmpeg.org/trac/ffmpeg/wiki/Using%20FFmpeg%20from%20PHP%20scripts) suggests using shell_exec over ffmpeg-php. Some other pages suggests using ffmpeg-php. Which method is better ? Is ffmpeg-php compatible with latest versions of php ? My only purpose is to convert any videos hosted by the user into mp4 (h.264,aac).
