#24(FFmpeg:new): Error message needed when enabling drawtext filter without libfreetype

#24: Error message needed when enabling drawtext filter without libfreetype -------------------------+------------------------------------------------- Reporter: xj25vm | Owner: michael Type: | Status: new enhancement | Component: FFmpeg Priority: normal | Keywords: configure libfreetype drawtext Version: git | filter Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 -------------------------+------------------------------------------------- It would be really helpful if the configure script would issue an error message when trying to do "--enable-filter=drawtext" without adding "--enable-libfreetype". At the moment, there is no error message, and the drawtext filter doesn't get enabled. The documentation of the drawtext filter does mention then libfreetype is needed - but it would be much more helpful if the configure script would do this check. Otherwise one would have no idea why the filter silently refuses to enable with no error message. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/24> 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!
