问题 On a dev site, i've been testing mp4 files for html5 play in safari. The native player loads and plays the mp4 files fine, even without the correct MIME type declaration. But, if I add AuthType Basic to my .htaccess the files fail sometimes fail to play and sometimes play in the quicktime player. After logging in with a valid user why would this directive stop mp4 files from playing correctly? 回答1: still have the same problem. some people solved it, while adding the mime types to their

H.264 muxed to MP4 using libavformat not playing back

阅读更多关于 H.264 muxed to MP4 using libavformat not playing back

问题 I am trying to mux H.264 data into a MP4 file. There appear to be no errors in saving this H.264 Annex B data out to an MP4 file, but the file fails to playback. I've done a binary comparison on the files and the issue seems to be somewhere in what is being written to the footer (trailer) of the MP4 file. I suspect it has to be something with the way the stream is being created or something. Init: AVOutputFormat* fmt = av_guess_format( 0, "out.mp4", 0 ); oc = avformat_alloc_context(); oc-

Bootstrap 3 - Responsive mp4-video

阅读更多关于 Bootstrap 3 - Responsive mp4-video

问题 I tried to find a good solution on the bootstrap site but I didn't get an answer to this yet. I think I can't be the only one struggling with this, but I couldn't find anything that helped me. I'm trying to embed an mp4-video on my website. The problem is, that if I use an iframe-tag I can't use autoplay and loop. Because of that I would like to solve it with a video tag (or something else that supports autoplay and loop). After that I tried to make my video responsive with an object-tag but

Flush & Latency Issue with Fragmented MP4 Creation in FFMPEG

阅读更多关于 Flush & Latency Issue with Fragmented MP4 Creation in FFMPEG

问题 I'm creating a fragmented mp4 for html5 streaming, using the following command: -i rtsp://172.20.28.52:554/h264 -vcodec copy -an -f mp4 -reset_timestamps 1 -movflags empty_moov+default_base_moof+frag_keyframe -loglevel quiet - "-i rtsp://172.20.28.52:554/h264" because the source is h264 in rtp packets stream from an ip camera. For the sake of testing, the camera is set with GOP of 1 (i.e. all frames are key frames) "-vcodec copy" because I don't need transcoding, only remuxing to mp4. "

MP4 Atom Parsing - where to configure time…?

阅读更多关于 MP4 Atom Parsing - where to configure time…?

问题 I've written an MP4 parser that can read atoms in an MP4 just fine, and stitch them back together - the result is a technically valid MP4 file that Quicktime can open and such, but it can't play any audio as I believe the timing/sampling information is all off. I should probably mention I'm only interested in audio. What I'm doing is trying to take the moov atoms/etc from an existing MP4, and then take only a subset of the mdat atom in the file to create a new, smaller MP4. In doing so I've
