#412(undetermined:new): .smv container support

#412: .smv container support --------------------------+-------------------------- Reporter: iohanntachy | Type: enhancement Status: new | Priority: wish Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- First of all sorry the bad english. SMV file is used in portable media players with SigmaTel chip. SMV files start with WAV header, so it plays as if was an wav file, without video. MultimediaWiki explain this kind of file (it even gives the meaning of each part of the header) http://wiki.multimedia.cx/index.php?title=SMV .SMV video samples: http://samples.mplayerhq.hu/smv/ I think it's not very hard to implement this kind of container. I would be very apreciated if you guys consider implementing this. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/412> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#358: MMS(MMSH) seeking/skipping freezes video --------------------------+-------------------------- Reporter: arnova | Type: defect Status: new | Priority: normal Component: undetermined | Version: unspecified Keywords: mms | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- When trying to seek/skip through a streamed video using the MMS/MMSH protocols, FFmpeg/FFPlay freezes. I first encountered this problem in XBMC but FFPlay experiences the same behaviour. I've tested it with several Dutch streams, which all show the problem. It works fine when I use an older version of XBMC which uses libmms so it seems to be a problem FFmpeg's implementation. The commandline/output from ffplay looks like this: (1000 ~/ffmpeg)% ./ffplay "mmsh://bolt01.omroep.nl/public/ug- od/wm/50/media/wm50c1/ceres/1/kro/rest/2009/KRO_1336806/bb.20090611.asf?wmt=4e292053&wmhash=15605a15" ffplay version N-31601-gba99474, Copyright (c) 2003-2011 the FFmpeg developers built on Jul 22 2011 08:56:44 with gcc 4.4.3 configuration: libavutil 51. 11. 0 / 51. 11. 0 libavcodec 53. 8. 0 / 53. 8. 0 libavformat 53. 6. 0 / 53. 6. 0 libavdevice 53. 2. 0 / 53. 2. 0 libavfilter 2. 27. 2 / 2. 27. 2 libswscale 2. 0. 0 / 2. 0. 0 Input #0, asf, from 'mmsh://bolt01.omroep.nl/public/ug- od/wm/50/media/wm50c1/ceres/1/kro/rest/2009/KRO_1336806/bb.20090611.asf?wmt=4e292053&wmhash=15605a15': Metadata: WMFSDKVersion : 10.00.00.4001 WMFSDKNeeded : 0.0.0.0000 IsVBR : 0 Duration: 00:10:09.14, start: 0.000000, bitrate: N/A Stream #0.0(eng): Video: wmv3 (Main), yuv420p, 320x180, 452 kb/s, 25 tbr, 1k tbn, 1k tbc Stream #0.1(eng): Audio: wmav2, 44100 Hz, 2 channels, s16, 48 kb/s ALSA lib pcm.c:7245:(snd_pcm_recover) underrun occuredB sq= 0B f=0/0 Read data packet header failed! 0KB vq= 0KB sq= 0B f=0/0 f=0/0 Recv other type packet -5 Read data packet header failed!
