问题 I need to play the 3gp , mov and mp4 videos in the media player. Right now I am using JavaFx media player but it supports only mp4 videos.

问题 I'm getting this error. From what I can google, it needs to configure the webpack file but in this rails app it's a webpacker.yml file. CRA looks like it works fine when using the usual tag.

问题 I'm working in a django project and i've run into an issue using embedded videos with bootstraps card-columns. We have a django plugin, Media Player, that simply puts a div & iframe on the page, most of the JS comes from the websites. The videos in question are from youtube, but i've tried vimeo videos and same result. The issue is that some videos work fine, but others don't show up on the page, they are blank/white. However, the video is still there, it takes up space & i can hover over it

问题 In my previously opened topic: How to make FFmpeg automatically inject mp3 audio tracks in the single cycled muted video I've got detailed explanation from @llogan how to broadcast looped short muted video on youtube automatically injecting audio tracks in it without interrupting a translation.

问题 If you convert from mjpeg to mp4 (libx264) with FFmpeg, Playback can not be performed on Windows · Mac. Thumbnails are not displayed on the icon. However, with the HTML5 Video tag, playback is possible. Why? Please tell me if you understand. Thank you. ffmpeg -i source_file.mov -b 4000k -vcodec libx264 destination_file.mp4 回答1: The usual reason for this is the pixel format. The MJPEG may have 4:2:2 or 4:4:4 chroma sampling which most players don't support in H264. So try ffmpeg -i source_file

问题 Using HLS.js (() => { var video = document.getElementById('video'); console.log('VIDEO',video); if(Hls.isSupported()) { var hls = new Hls(); hls.loadSource('https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8'); hls.attachMedia(video); hls.on(Hls.Events.MANIFEST_PARSED,function() { //https://github.com/video-dev/hls.js/blob/master/docs/API.md#quality-switch-control-api //console.log('RAHUL',hls.levels); video.play(); }); } // hls.js is not supported on platforms that do not have Media Source

问题 This seems to be a recurring problem, as seen here: ffmpeg Error while filtering: Cannot allocate memory . I ask this only because that question has no answer. I get a memory error every time I try to use amerge to combine music and a video (with audio). I am at a loss as to how to get around this, so if there are any other command line alternatives that do the same thing (combining audio with video, merging the new audio and the current audio on the video) any suggestions would be much

问题 From FFMPEG's GitHub, I use the encode_video.c to generate a 1 second video. Here is the example in question: https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/encode_video.c I compile with: gcc -Wall -o ffencode encode_video.c -lavcodec -lavutil -lz -lm Clean compile, zero warnings. I test the program by running: ./ffencode video.mp4 libx264 Lots of stats printed out (expected based on source code) as well as ffmpeg logs, but ultimately no errors or warnings. However, then the
