#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

I then verified that the resulting file still had the transparency by using it as an overlay in Final Cut. I then transcoded the file to Prores4444 again, this time using ffmpeg. Importing that video into Final Cut Pro and used that as an overlay which did not work (i.e. transparency was gone). Command line used (current ffmpeg with a patch Carl sent me on the ML today): ffmpeg -i ~/testdata/video/finalcut- output/prores4444_with_transparency.mov -vcodec prores_kostya -pix_fmt yuv444p10le -acodec copy ~/tmp/prores4444_with_transparency_ffmpeg_patched.mov ffmpeg version N-44391-gf9dd2e5 Copyright (c) 2000-2012 the FFmpeg developers built on Sep 12 2012 12:09:31 with gcc 4.2.1 (GCC) (Apple Inc. build 5664) configuration: libavutil 51. 72.100 / 51. 72.100 libavcodec 54. 55.100 / 54. 55.100 libavformat 54. 26.101 / 54. 26.101 libavdevice 54. 2.100 / 54. 2.100 libavfilter 3. 16.103 / 3. 16.103 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 15.100 / 0. 15.100 Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/Users/krueger/testdata/video /finalcut-output/prores4444_with_transparency.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2012-09-12 08:48:56 Duration: 00:00:00.04, start: 0.000000, bitrate: 43461 kb/s Stream #0:0(eng): Video: prores (ap4h / 0x68347061), yuv444p10le, 1920x1080, 40697 kb/s, SAR 1:1 DAR 16:9, 25 fps, 25 tbr, 25 tbn, 25 tbc Metadata: creation_time : 2012-09-12 08:48:56 handler_name : Apple Alias Data Handler timecode : 01:00:00:00 Stream #0:1(eng): Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, stereo, s16, 1536 kb/s Metadata: creation_time : 2012-09-12 08:48:56 handler_name : Apple Alias Data Handler Stream #0:2(eng): Data: none (tmcd / 0x64636D74) Metadata: creation_time : 2012-09-12 08:48:57 handler_name : Apple Alias Data Handler timecode : 01:00:00:00 Output #0, mov, to '/Users/krueger/tmp/prores4444_with_transparency_ffmpeg_patched.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt encoder : Lavf54.26.101 Stream #0:0(eng): Video: prores (ap4h / 0x68347061), yuv444p10le, 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 25 tbn, 25 tbc Metadata: creation_time : 2012-09-12 08:48:56 handler_name : Apple Alias Data Handler timecode : 01:00:00:00 Stream #0:1(eng): Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, stereo, 1536 kb/s Metadata: creation_time : 2012-09-12 08:48:56 handler_name : Apple Alias Data Handler Stream mapping: Stream #0:0 -> #0:0 (prores -> prores_kostya) Stream #0:1 -> #0:1 (copy) Press [q] to stop, [?] for help frame= 1 fps=0.0 q=0.0 Lsize= 141kB time=00:00:00.04 bitrate=28897.2kbits/s video:132kB audio:8kB subtitle:0 global headers:0kB muxing overhead 1.286356% I'll attach the Prores4444 file generated Final Cut Pro and the PNG used to create the video.
