BUG: input source 4K ouput Full HD
by Phil Forneur 14 Apr '19

14 Apr '19

Hi, *codec of source video*: Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt2020nc/bt2020/bt709), *3840x2160*, 48107 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 30 tbr, 90k tbn, 180k tbc (default) *OS *win10 64bits When I play this 4K video with either SMPlayer 18.10 (64bits) or VLC 3.0.4 AND I output on a *full HD*(1920x1080@60Hz) it does show a very poor image quality; note that this does not happen with windows media player. But, if I play the *same *video, but I *output on a 4K monitor*, than the image is superb. Thanks for fixing this bug.

PgUp/PgDn don't work for video
by arthurpeabody 14 Apr '19

When viewing a video, PgUp returns, 'No bind found for key 'KP9'', when pressed on the laptop's keyboard, but works on an external (USB) keyboard. It works for plain audio.

[twitch] ads reset mplayer to initial configuration
by sylvain.bertrand＠gmail.com 04 Apr '19

04 Apr '19

Hi, I watch twitch streams pipelining the hls concatened mpeg ts segments to mplayer stdin. The issue is when a twitch stream switches from ads to live stream or the other way around, mplayer settings are reset. For instance if I did switch to fullscreen display and/or muted the stream, the settings are reset going back to a unmuted stream and/or window display. I did try to switch to ffmpeg mpeg ts demuxer without success. -- Sylvain

Possible to get full track path in slave mode?
by Alec Bennett 30 Mar '19

30 Mar '19

Looking over the docs for slave mode: http://www.mplayerhq.hu/DOCS/tech/slave.txt I see "get_file_name", which returns the basename of the currently playing track, but I don't see a way to get the complete path of the currently playing track. Is there some clever way to get the complete path?

Incorrect play (no HTML mail)
by Raf-9600 17 Dec '18

17 Dec '18

Brakes at the beginning this video https://openload.co/f/unw98thbz04/logo.mpg Win10 x64, GeForce 1050 Ti. mplayer-svn-38117 I start the video player without any settings at all. Is this a video player error or do you need special commands so that the playback is correct? Absolutely all other video players play this file normally. The problem is only with mplayer. The best result I managed to achieve so: mplayer.exe logo.mpg -audiofile logo.mpg. But not perfect. You will help?

MPlayer, RTSP, live555 and audio
by Michael Kohne 14 Dec '18

14 Dec '18

I'm trying to use mplayer to play video from a Sony IP camera (the EP-580). I've built the latest mplayer (from yesterday, SVN 38117), and had it grab ffmpeg itself. I'm building with the Live555 libraries in place (I'm on CentOS 6, and the Live555 version I have is 2012.01.25 - that was the one I could easily find packaged already in the nux repo). If I disable audio on the camera, I can run mplayer thusly: ./mplayer -prefer-ipv4 -rtsp-port 62000 rtsp://192.168.0.113/media/video1 And it works great (Camera is doing 1920x1080 @ 30 fps, 4096kbps). Video looks good. If I enable audio on the camera (even if I end up leaving the microphone unplugged), then I never see an image, and mplayer exits after a second or so: MPlayer SVN-r38117-4.9.1 (C) 2000-2018 MPlayer Team Playing rtsp://192.168.0.113/media/video1. Connecting to server 192.168.0.113[192.168.0.113]: 554... A single media stream only is supported atm. rtsp_session: unsupported RTSP server. Server type is 'unknown'.

(End of file) I've poked around the lists a bit, and found references to using ffmpeg to do rtsp: ./mplayer -prefer-ipv4 -rtsp-port 62000 ffmpeg://rtsp:// 192.168.0.113/media/video1 I tried that with audio both enabled and disabled on the camera and got the same results: The video is jerky and useless because it's missing RTP packets (I get a steady stream of messages indicating losses of up to 300 packets at a go). Note that I also didn't hear any audio, but that could just be because it couldn't get enough data in a row to play it. Other things I've tried: rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov This locks up, same as the camera ffmpeg://rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov This plays video, but no audio. There's no messages about dropped RTP packets, and no indications of bad video, just...no audio comes out. Latest Live555 libraries: No good. They changed their API in April 2013, and MPlayer has never been updated to the new API. There's a patch floating around that builds, but it produced no difference in operation. ( http://lists.mplayerhq.hu/pipermail/mplayer-users/2013-July/086408.html https://git.trafficking.agency/teddydestodes/arietta_buildroot/raw/37895972… ) Conclusions: mplayer's use of ffmpeg as an rtsp client can't keep up with my camera, and may have audio problems. mplayer's use of the Live555 libraries is somehow broken when multiple streams are in play. Is there anything else I should be trying to get this going before I start trying to learn how the demuxers work? I'm starting to dig through the DOCS/tech directory now, but if there's a way to fix this without having to dive into the RTP demuxer code, I'd be most grateful. Thank you.

Hey everyone, is it possible to use one of the controllibs (mpvlib or mpv-python) to make mpv switch streams while playing internet-audiostreams with it? Philipp

Frame dropping with vdpau deint on a 4K monitor
by Scott W. Larson 10 Nov '18

10 Nov '18

When I run mplayer with this command on my 1920x1200 monitor: mplayer-vo vdpau:deint=3 -vc ffmpeg12vdpau 1080i-file.mp4 It runs perfectly. But when I run the same command in a 1920x1080 window on my 3840x2160 monitor on the same system it drops about ten frames per second. What could be causing slowing down the hardware deinterlacing?

Problem with proxies and playlists
by David Woodfall 07 Nov '18

07 Nov '18

I've been trying a proxy with mplayer and noticed that if a playlist is used then the proxy is ignored. This works: mplayer http_proxy://192.168.1.2:33000/http://bbcmedia.ic.llnwd.net/stream/bbcmedia_radio4extra_mf_q This doesn't: mplayer -playlist http_proxy://192.168.1.2:33000/http://open.live.bbc.co.uk/mediaselector/5/select/version/2.0/mediaset/http-icy-aac-lc-a/format/pls/vpid/bbc_radio_three.pls Is there any way around this?
