The method comprises including an auto-play script in a webpage downloaded to the web environment, wherein the web environment is disabled to auto-play video clips; and executing the auto-play script within the web environment, wherein the execution of the auto-play script causes at least: receiving the video clip from an external source and automatically playing the video clip in the web environment. ## Claims ### Claim 1 A method for auto-playing a video clip within a web environment of a mobile computing device, comprising: including an auto-play script in a webpage downloaded to the web environment, wherein the web environment is disabled to auto-play video clips; and executing the auto-play script within the web environment, wherein the execution of the auto-play script causes at least: receiving the video clip from an external source and automatically playing the video clip in the web environment. ### Claim 2 (depends on 1) The method of claim 1, wherein executing the auto-play script within the web environment further comprises: receiving a set of parameters related to the video clip; downloading video bytes of the video clip from the external resource; parsing the downloaded video bytes to detect at least encoded video frames; decoding the encoded video frames using an emulated video decoder; and rendering the decoded video frames into the web environment. ### Claim 3 (depends on 2) The method of claim 2, further comprising: determining a video format of the video clip; using the emulated video decoder respective of the determined video format. ### Claim 4 (depends on 2) The method of claim 2, wherein rendering the decoded video frames into the web environment is performed using an HTML5 canvas tag. ### Claim 5 (depends on 2) The method of claim 2, wherein the emulated video decoder is coded using a scripting programming language. ### Claim 6 (depends on 5) The method of claim 5, wherein the auto-play script is coded using a scripting programming language, wherein the scripting programming language is at least a JavaScript. ### Claim 7 (depends on 2) The method of claim 2, further comprising: determining if a color space of the decoded video frames is a YUV color space; and converting the decoded video frames having a YUV color space into a RGB color space, upon determining if the color space of the decoded video frames is a YUV color space. ### Claim 8 (depends on 7) The method of claim 7, wherein converting the decoded video frames from the YUV color space into the RGB color space further comprises: performing a WebGL conversion. ### Claim 9 (depends on 8) The method of claim 8, wherein performing the WebGL conversion further comprises: creating a YUV WebGL canvas object; instantiating a WebGL context with a shader program; segmenting, using the object, each decoded video frame into YUV components; performing, using the object, a red-green-blue (RGB) transformation of the YUV components, wherein the RGB transformation results in RGB images; rendering video using the RGB images. ### Claim 10 (depends on 9) The method of claim 9, wherein the rendering of the RGB images further comprises: repetitively rendering RGB images into a HTML5 canvas. ### Claim 11 (depends on 1) The method of claim 1, wherein the web environment includes any one of: a web browser, a mobile application, a web application, and a native application. ### Claim 12 A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute a process for auto-playing a video Clip within a web environment of a mobile computing device, the process comprising: including an auto-play script in a webpage downloaded to the web environment, wherein the web environment is disabled to auto-play video clips; and executing the auto-play script within the web environment, wherein the execution of the auto-play script causes at least: receiving the video clip from an external source and automatically playing the video clip in the web environment. ### Claim 13 A mobile computing device, comprising: at least one processor; and a memory, the memory containing instructions that, when executed by the at least one processor, configure the mobile computing device to: include an auto-play script in a webpage downloaded to a web environment, wherein the web environment is disabled to auto-play video clips; and execute the auto-play script within the web environment, wherein the execution of the auto-play script by the at least one processor causes at least: receiving the video clip from an external source and automatically playing the video clip in the web environment. ### Claim 14 (depends on 13) The mobile computing device of claim 13, wherein the mobile computing device is further configured to: receive a set of parameters related to the video clip; download video bytes of the video clip from the external resource; parse the downloaded video bytes to detect at least encoded video frames; decode the encoded video frames using an emulated video decoder; and render the decoded video frames into the web environment. ### Claim 15 (depends on 13) The mobile computing device of claim 13, wherein the mobile computing device is further configured to: determine a video format of the video clip; use the emulated video decoder respective of the determined video format. ### Claim 16 (depends on 14) The mobile computing device of claim 14, wherein rendering the decoded video frames into the web environment is performed using an HTML5 canvas tag. ### Claim 17 (depends on 16) The mobile computing device of claim 16, wherein the emulated video decoder is coded using a scripting programming language. ### Claim 18 (depends on 17) The mobile computing device of claim 17, wherein the auto-play script is coded using a scripting programming language, wherein the scripting programming language is at least a JavaScript. ### Claim 19 (depends on 14) The mobile computing device of claim 14, wherein the mobile computing device is further configured to: determine if a color space of the decoded video frames is a YUV color space; convert the decoded video frames having a YUV color space into a RGB color space, upon determining if the color space of the decoded video frames is a YUV color space. ### Claim 20 (depends on 19) The mobile computing device of claim 19, wherein the mobile computing device is further configured to: perform a WebGL conversion to convert the decoded video frames having a YUV color space into a RGB color space. ### Claim 21 (depends on 20) The mobile computing device of claim 20, wherein the mobile computing device is further configured to: create a YUV WebGL canvas object; instantiate a WebGL context with a shader program; segment, using the object, each decoded video frame into YUV components; perform, using the object, a red-green-blue (RGB) transformation of the YUV components, wherein the RGB transformation results in RGB images; render video using the RGB images. ### Claim 22 (depends on 21) The mobile computing device of claim 21, wherein the mobile computing device is further configured to: repetitively render RGB images into a HTML5 canvas. ### Claim 23 (depends on 13) The mobile computing device of claim 13, wherein the web environment includes any one of: a web browser, a mobile application, a web application, and a native application.
