FFmpeg conversion failed Issue [closed]
20 avril, par Hillol TalukdarI'm trying to convert a video file using FFmpeg, but the process fails and shows some errors that I don't fully understand the cause of. How can I avoid the error and fix the issue? Below is the command I used and the output I received.
Command: [-y, -hide_banner, -i, saf:12.VOB, -map, 0:3, -c:s:0, dvdsub, -map, 0:2, -map, 0:1, -f, mp4, -vcodec, copy, -map_metadata, 0:g, -acodec, aac, -async, 1, saf:13.mp4]

hevc_videotoolbox encoding failed
19 avril, par TheCoderProI have some downloaded My Hero Academia episodes, and I'm trying to put them on my iPad that hasn't got that much space. So, I decided to try convert them to HEVC. But, when I try to use hevc_videotoolbox for GPU acceleration. But, it doesn't work.

How to convert an ffmpeg texture to Open GL texture without copying to CPU memory
19 avril, par PPPThis ffmpeg example demonstrates how to do hardware decoding: https://github.com/FFmpeg/FFmpeg/blob/release/4.2/doc/examples/hw_decode.c
At line 109 it does this:
/* retrieve data from GPU to CPU */ if ((ret = av_hwframe_transfer_data(sw_frame, frame, 0)) < 0) {I want to avoid this because it takes time. Therefore, I need a way to reuse that decoded video, which is in GPU memory, to redo color conversion.
How to transform the decoded texture in GPU memory to texture in Open GL without getting it back to CPU memory like in the code above?
If the above is not possible, how to do color conversion in the decoded video using open gl? I heard that ffmpeg supports passing opengl shaders as input, so I guess it's possible.

OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error
19 avril, par user2262504I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.
It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec 'libx264'" error.
Anyone has ideas to solve this problem?
More specifically:
- anyone knows where and how OpenCV invoke ffmpeg API?
- how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV?
- will changes of default in ffmpeg be carried to libx264?
