[PATCH] add support of compression algorithm 3 in mkv demuxer
by Alexander Beregalov 02 Jan '12

02 Jan '12

Specs from http://www.matroska.org/technical/specs/ : ContentCompAlgo The compression algorithm used. Algorithms that have been specified so far are: 0 - zlib, 1 - bzlib, 2 - lzo1x, 3 - Header Stripping. ContentCompSettings Settings that might be needed by the decompressor. For Header Stripping (ContentCompAlgo=3), the bytes that were removed from the beggining of each frames of the track. I have such file, it works for me. | + A track | + Track number: 2 | + Track UID: 2 | + Track type: audio | + Lacing flag: 1 | + Default flag: 1 | + Codec ID: A_AC3 | + Content encodings | + Content encoding | + Content compression | + Algorithm: 3 (header removal) | + Settings: length 2, data: 0x0b 0x77 See an attachment. Please comment.

[PATCH] Network synchronized playback using UDP
by Jason Holt 08 Sep '10

08 Sep '10

I hacked in a simple mechanism to synchronize playback between multiple instances of mplayer over a network. The master sends a UDP datagram to announce its position in the video each time it plays a frame. The slaves check to see if they're within epsilon of the master. If they are, they just advance by a frame. If not, they seek to where the master is. This works out nicely because I can dynamically tweak frame rate, seek and pause on the master and the slaves all follow along. The patch is not compliant with your coding standards. Before I do that work, I wanted to make sure it's a patch you're interested in, and see if you have any particular guidance on things I should move or change.

[PATCH] add FFmpeg-style "quiet" compilation

branching off rc4
by Attila Kinali 06 Aug '10

06 Aug '10

Moin, As ffmpeg-0.6 has been released, we should start thinking about doing an rc4 release, because rc3 does not compile with ffmpeg-0.6. This is a problem for all distros which whant to link mplayer against the system ffmpeg/lav*. Are there any patches, fixes, cleanups around that should be in rc4? Are there any known regressions or bugs that should be fixed before a release? Attila Kinali -- If you want to walk fast, walk alone. If you want to walk far, walk together. -- African proverb

[PATCH] Fixing dvd:// support
by Olivier Rolland 02 Aug '10

02 Aug '10

Hi, Here are 3 patches to fix some issues in stream_dvd.c : - The first one fixes the incorrect assumption that the number of chapters of a DVD title is equal to the number of cells. - The second one improves seeking by chapters. The current code seeks to the starting position of the chapter. From this position, it then tries to figure out the starting cell. This is completely suboptimal and error prone since the starting cell can be directly deduced from the chapter. - The third one improves seeking by position. The current code takes the angle into account. This is a mistake since the position is independent of the angle. Please, apply the patches in order. Regards, Olivier

[PATCH] Tags support for SubRip and MicroDVD subtitles [v3]
by ubitux 24 Jul '10

24 Jul '10

Hi, The patch is about to be done; the only thing that can be missing is an option to enable/disable the style. At the moment, the -ass switch makes it available or not (old parsing, stripping tags). A lot of the changes are not mine since it's a port of the tmp_sub branch from Uoti's mplayer-git. The code has been tested a few times, most of SubRip & MicroDVD tags are supported, stylising is also available if muxed subtitle (it tries to parse SubRip), and it does not require modifications to the libass. Regards, -- ubitux

[PATCH] fix reordering
by Dan Oscarsson 18 Jul '10

18 Jul '10

When seeking some demuxers (for example demux_ts.c) returns MP_NOPTS_VALUE for first video frame after the seek. For the mpeg-ts files I have -correct-pts hate to be set for them to play correctly. Unfortunately the reordering code in libmpcodecs/dec_video.c ignores a frame, if the pts have value MP_NOPTS_VALUE, resulting in one frame being out of order in each set of frames after a seek. This gives bad video playback. As I have written in the patch, I cannot see that including MP_NOPTS_VALUE in the reordering should be a problem, as it is a large negative value (at least on my computers), and sorts before the following frames.

[PATCH] Coreaudio patches (audio device selection and deprecated functions)
by Adrian Stutz 12 Jul '10

12 Jul '10

Hello list, The ao_coraudio output has an issue on 10.6, loosing it's audio output whenever plugging/unplugging headphones. I was investigating the issue when I noticed a lot of deprecated functions in ao_coreaudio. The first patches replace those functions with their newer ones (which is pretty straight-forward because the functionality didn't change). I decided to split out repeated tasks into separate functions (like getting an array from the API) to simplify the code. Some of the functions where deprecated in 10.5, most in 10.6. All new functions are available in 10.4, which IIRC is the minimum requirement elsewhere already. coreaudio_1_UInt32_printf.diff > Change printf placeholders of UInt32 variables to PRIu32 (gcc was complaining about these) coreaudio_2_replace_deprecated_functions.diff > Replace all deprecated function calls with their new counterparts coreaudio_3_int_to_UInt32.diff > Correct use of int instead of UInt32 in two places The new functionality allows to select an audio device by its id, while the default and 0 selects the default device. It also sets the selected device as the current device, which makes ao_coreaudio correctly switch devices when default device is selected and changes. Selecting a specific device will stick to it. coreaudio_4_device_id_option.diff > Add the new option and correctly handle setting the default / a specific device. I wasn't able to actually verfiy SPDIF output apart from checking it produces noise on regular speakers so it would be great of someone could test that! Greetings, Adrian

by Marton Balint 11 Jul '10

11 Jul '10

Hi, The attached patch fixes vo_tga to set the alpha channel to 0xff instead of the blue channel, and copy the blue channel data properly from the source buffer. Regards, Marton
