patch backlog maintenance
by Diego Biurrun 19 Jun '08

19 Jun '08

Folks, I'm awfully overloaded. Could somebody take over the maintenance of the patch backlog that I took over from Attila some time ago? All you need to do is keep track of all unapplied patches in an mbox or something and make it available from time to time. Sending out periodic reminders from time to time is a plus. Thanks Diego

Synchronization of players in LAN
by J.A. Gutierrez 18 Jun '08

18 Jun '08

Hello I'm trying to synchronise several players running on several computers connected to a dedicated 10/100 Ethernet switch. Each one reads a different movie (video only) from its internal hard disk, and resolution will be 768x576. I'm thinking of a simple solution: - Add some code at mplayer startup so it will wait for an UDP broadcast packet (sent by a central master in the LAN). This way all the players would start at the same time. - Use NTP to keep in sync all the computers' clocks, and trust mplayer's rtc synchronisation feature. With this simple setup, could we be sure all the players would keep the synchronisation? Or should the master computer track them all and take control on their speeds? How difficult would be to add code so all the player synchronise using the LAN? Or should I use some external clock connected to all serial ports? Or use a totally different approach? Thanks. -- finger spd(a)shiva.cps.unizar.es for PGP / .mailcap tip of the day: / La vida es una carcel application/ms-tnef; cat '%s' > /dev/null / con las puertas abiertas text/x-vcard; cat '%s' > /dev/null / (A.

[PATCH] Fix vf_expand in with non-direct caps
by Pascal Massimino 30 May '08

30 May '08

Hi, attached patch makes sure vf_expand is dealing with direct-capable image before trying to use direct rendering for expanding. I've seen this problem with encoding, where the codec's replicated edges could be made visible upon expansion. skal

[PATCH] Video mixer with mencoder Part 5/1
by Ötvös Attila 29 May '08

29 May '08

Hi All! This patch is big because download from: http://onebithq.com/root/mplayer/videomixer/download/20080102 Patch file: stream.patch Depend: none I rewrited my shmem stream handle and new pipe mode to sync read/write: stream_shmem.c I create raw video and raw audio encoder to shmem (based ae_pcm & ve_raw): ae_shmem.c and ve_shmem.c I create muxer and demuxer to shmem stream: muxer_shmem.c and demux_shmem.c The mencoder can encoding video/audio to shmem. The mencoder or mplayer can read from shmem. Example: mencoder file.avi -o shmem://1 mplyer shmem://1 Best regards! Attila

[PATCH] libmpeg2 - bogus output qscales for interlaced content
by Jindrich Makovicka 19 Feb '08

19 Feb '08

Hi, Currently, MPEG2 postprocessing corrupts the image when the content is interlaced. The reason is that our patched libmpeg2 stores the qscales _twice_ into the top half of the quant_store, while the bottom one contains only garbage, which results in ugly artifacting in the bottom half of the image. The attached patch fixes this issue. The filters should be also adjusted to process interlaced content properly (maybe later), but at least the worst artifacting is gone and resulting video is watchable. Regards, -- Jindrich Makovicka

[PATCH] Support for XvMC VLD on S3 Unichrome
by Timothy Lee 18 Feb '08

18 Feb '08

Dear all, This patch was originally from Ivor Hewitt, and adds XvMC VLD support to MPlayer. This significantly speeds up the playback of MPEG-2 video on S3 Unichrome. On a 1GHz VIA C3, the CPU load drops from 85% to 15% during playback. Since the majority of the patch was written by Ivor, I've sent it to him for review in July, but have not received any feedback since then. The only change that have been added is the ability to disable VLD acceleration during run-time if not supported by the display driver. I've tested a patched MPlayer against Intel, NVidia and Unichrome display drivers, and had consistently achieved the highest level of XvMC acceleration. I've been posting updates of this patch to the Unichrome mailing list during last 5 months, and their subscribers had not encountered any problem with their patched MPlayers. It would be great to get XvMC VLD support on the trunk. Looking forward to your comments! Regards, Timothy Lee

Audio visualization
by mail 17 Feb '08

17 Feb '08

Hello MPlayer developers! I'm newbie in in this list and I wonder if somebody has ever worked at audio visualization support in mplayer. The point is that now I have a number of tasks that need it and I'm working to implement it. By audio visualization I understand generating video (depending on audio or not) while audio playback. I have some ideas and first of all would like to know what developers society think about this. Thank you for your consideration. -- Pavel Modilaynen

[PATCH] Recursively Nested ASX Playlists
by Mrc Gran 17 Feb '08

17 Feb '08

Hello, I'm sending a patch to make mplayer capable of playing recursively nested asx playlists. A nested asx playlist is one whose refs point to further asx list files instead of real media files such as wmv. (This patch is not to be confused with processing of entryrefs which seems to be already implemented at asxparser.c.) Both asx playlists and wmv files are of mime type x-ms-asf. This patches modifies stream/asf_streaming.c so that it looks for a file ending with '.asx' which, if found, returns a demux_type_playlist to mplayer.c instead of the expected demuxer_type_asf. This triggers mplayer.c to synchronously follow the recursive nested playlists. A new streaming type ASF_ASXPlaylist_e is added to asf.h to control the new code branch. The function play_tree_parser_get_line() also receives a new code branch to deal with buffered streams which is necessary in order to parse the playlist, buffered when the asf stream was opened. I felt the necessity to develop this patch because there are sites which use nested asx playlists, such as video.globo.com (see discussions at http://sourceforge.net/forum/forum.php?thread_id=1668761&forum_id=242727 and http://sourceforge.net/mailarchive/forum.php?thread_id=31642270&forum_id=21…) and nested playlists are part of the microsoft specification for asx ( http://msdn2.microsoft.com/en-us/library/bb262812.aspx) I also tested the patch against www.bbc.co.uk, www.cnn.com, http://wptv.wp.pl/news.html (mplayer -playlist http://i.wp.pl/a/f/asx/11771/wptvnews.asx) and all worked fine. Extra care was taken to modify the minimum amount of code and to minimize potential regressions. In case this patch is approved for inclusion in mplayer, I would be grateful if my name was cited in the list of contributors. All comments welcome. Thanks, Marcus C. Granado mrc [d-o-t] gran [a-t] gmail [d-o-t] com --
