  • How to Embed CEA-608 Subtitles in Video using FFMPEG

    25 septembre 2018, par Yogesh Agarwal

    How can i embed CEA 608 subtitles via ffmpeg in a video ? I have SRT file and i can embed that via ffmpeg but it doesnt show up in facebook. It requires a CEA 608 Format of subtitles to be embedded inorder to show up in streams.

    I am quite clueless here. I found libcaption plugin that can do it, but i am not sure how to install it as my repo doesnt have it. Any Pointers would greatly help me ! :)

    There is one more plugin

    libass

    which can hardcode but i am not comfortable using it.

  • Using ffmpeg to play file on windows, should use directshow to render the decoded frame [on hold]

    22 juillet 2013, par Terry

    I want to write a video file player using ffmpeg(support many format).

    However ffmpeg(/ffplay.exe) using SDL to render the video frame and play the audio sound. I only want to support windows platform. I think the default windows technology/api is more suitalbe for me to render the decoded frame. Do you think so ?

    If so, should I use direct show, or just using direct draw for video frame and direct sound for audio frame.

    If using direct show, I think I need to wrapper a direct show source filter(/splitter), then pass down the decoded video/audio frame data to render filter.

    Please help me which is the best choice ?

  • A video player based on QtAV with Direct2D / OpenGL rendering

    22 juin 2015, par ashikthomas

    I’m developing a video player in Qt C++ using QtAV. QtAV uses ffmpeg internally. I need to show semi transparent overlays both my watermark logo and subtitles. I’m writing the application for windows. I use OpenAL library. OpenGL and Direct2D are the choice for renderers.

    If I use OpenGL renderer, it works fine in some systems. The overlay works fine. But in some other systems the whole application will be just a black window. Nothing else I can see.

    If I use Direct2D, the overlay wont work. And the renderer is a bit slow. But it works on all systems, without this overlays.

    I have no code to show here because its not the coding issue. Even the examples in QtAV are not working. I need to find a way to show the overlays using Direct2D renderer OR find a solid way to use OpenGL rendering on all systems without fail.
