问题 We have an encoding process in place using ffmpeg on Mac OS X. This process will take a source video and a couple files from that: .m3u8 video, .mp4 video and .mp3 audio file. By default we've used the video from our m3u8 process which is a h264 (via libx264 ) video with AAC (via libfaac ) audio. We are mostly using these videos on mobile devices (hence the m3u8 files) but we also use the .mp4 files for Android, Windows Phone, etc. More and more we also need to offer these same videos on the

问题 I'm looking to remove the closed captions (EIA-608) from a H.264 video (contained as mkv) without reencoding. The closest I've got is using ffmpeg: ffmpeg -f lavfi -i movie=input.mkv[out+subcc] -map 0:0 output.mkv In order to separate the video into rawvideo and subrip components and export out the rawvideo. However this results in a file close to 200GB, which isn't really a sustainable solution. An ffmpeg based solution would be preferable, but I'm fine using whatever software is necessary.

问题 I have ubuntu 16.04 LTS and OpenCV 3.4.0 Installed(Intel i5 and AMD graphics card), I need to create a browser supported video, which is playable in browser. If I'm using H264 im getting OpenCV: FFMPEG: tag 0x34363248/'H264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)' OpenCV: FFMPEG: fallback to use tag 0x31637661/'avc1' [h264_nvenc @ 0x7f4e0407f5e0] Cannot load libcuda.so.1 Could not open codec 'h264_nvenc': Unspecified error if I'm using webm VP8 OpenCV: FFMPEG

问题 After reasearching for a few days, i m still lost with this issue: I have a webcam connected over WiFi to my Android device. I wrote an Android app to connect to a specified Socket of the webcam (IP and port). From this Socket i get an InputStream which is already encoded in H.264. Then i redirect this InputStream from the android device to my server, where i managed to decode it to images/frame by using Xuggler. I would like to stream my webcam live to the internet to a flash player or
