Last week in VideoLAN - 52

52nd VideoLAN report

Another summer week passes by and here is a new weekly report about the VLC and VideoLAN communities!

Features

VLC

The week started with numerous additions to the Direct3D video accelerations and video outputs, to continue the support for 10bits decoding and HDR.

Related to those improvements, we added support for hardware decoding of HEVC decoding inside the TS format, by improving our HEVC packetizer.

We fixed (actually added) the support of QuickTime Videos inside MKV, aka MP4-inside-MKV; and also the support for QuickTime Audio inside MKV.

We improved again the ChromeCast support, by fixing small issues, notably when reloading and stopping the stream.

In the core, an important deadlock was killed, that was affecting Windows and Android platforms.

Finally, we also did a fix for hidden chapters in MKV, and improved the MIDI integration for Windows, and reworked a bit our contrib system.

Android

On Android, we finally fixed the support for old x86 Phones like the ZenPhone that claimed to be ARM phones. Those phones lie about their CPU with CPU_ABI, CPU_ABI AND they expose a fake /proc/cpuinfo to the applications! Thanks to a contact at ASUS, we got a phone and coded a work-around.

We also added support for saving audio-delay when using your Bluetooth headphones, so that you have a different audio-delay when using those headphones than without headphones.

Finally, we fixed a few crashes and regressions that were reported against the last release.

WinRT

On UWP, the biggest focus was on cleaning the code and on the Xbox 1 interface.

More to come soon, I hope!

libbluray

We've had a lot of small fixes for libbluray, mostly on fixing issues and crashes reported by static analyzers, but also build issues, Windows issues, and crashes reported by the users.

That's all for this summer week! See you next!

Last week in VideoLAN - 51

51st VideoLAN report

So, after a few crazy weeks, I'm coming back to a more regular schedule for my weekly reports about VLC and VideoLAN.

Features

VLC

Decoder fallback

The major change, during last week, was the possibility to restart the audio decoders when the audio device changes.
This is very useful when you switch from normal decoders to SPDIF/HDMI pass-through for DTS, Dolby and related codecs.

In the past, VLC could only restart the filters, not the decoders, so our Dolby and DTS decoders were actually filters. This was finally changed and now decoders are decoders.

For those who don't understand what all this means, it means that it will help us support more formats for pass-through over HDMI, like DolbyDigital+ or DTS-HD.

Modules

We've fixed the green line that appears only on AMD GPUs on Windows. This is scheduled for the next Windows update.

I've implemented the support for browsing FTP remote directories, so that it behaves similarly to SFTP or SMB.

On Windows, we've added the support for hardware decoding of 10bits HEVC , using DxVA and D3D11.

We also pushed improvements to the prefetcher module and to our TTML support; and we've fixed issues for DVD menus, SAT>IP protocol and HLS protocol.

Finally, please note that the license of the UPnP module was switched from GPL to LGPL.

Android

On Android, we've fixed a few issues related to old devices, and we've improved the libVLC Java bindings to support statistics.

WinRT

Last week on WinRT, we've removed all the code that was focusing on older versions of Windows.

The codebase now support only Windows 10 Universal with its Anniversary Edition version.

That's all for this week!

Thanks for the support and see you soon!

Last weeks in VideoLAN - 50

50th VideoLAN report

So, after a few crazy weeks, I was taken a bit by RealLifeĀ©Ā®, and we've had 3 weeks without report. And this one is late. :)

Therefore, here is a new report about the VLC and VideoLAN communities, covering the last 3 weeks!

The report will be a bit more summarized that usual, and more dense in information, for obvious reasons. :)

Features

VLC

We've added support for codecs with colors in 12bit-depth, in YUV 4:2:0, 4:2:2 and 4:4:4. Of course, nothing can display that yet, but it can happen in some HEVC samples. It will be dithered down before displaying.

The Windows users will be happy, because we're reintroducing the MIDI support, using a new library called FluidLite, in order to replace FluidSynth.

A new protocol to control and distribute satellite signals on a LAN called SAT>IP was implemented in a new access module.

There was a lot of work and rework on our adaptive support, notably to change timings and drain, but also to start supporting HLS using mp4 fragments.

Some work on URL and URI was done to support more cases and improve test coverage. 2 new functions called vlc_uri_resolve() and vlc_uri_compose() were introduced.
At the same time, modifications on the HTTP redirections were merged.

On Windows, we merged the VP9 hardware decoding, using the DxVA APIs.
This code requires very recent video cards to be usable.

Finally, an important work was done to merge the access and stream-filter behavior and semantics. The 2 type of modules still exist, but a large part of the code is now common.
This allows now block-based stream filters.

To achieve this, we now have introduced the vlc_stream_Eof(), vlc_stream_ReadBlock() and vlc_stream_ReadPartial() functions.

Finally, we added support for MP4 chapters in Unicode, and we fixed some Qt sizing issues with Qt5, a DLL loading potential security issue for Win32, MP4 subtitles size, a WMV integer overflow, a crash in smem, the Qt right-click menu on the playlist, SFTP browsing, and the audio fingerprinter. We also improved the HTTP/2 stack, our TS demuxer when dealing with scrambled content, and a few other minor things I forgot.

Android

On Android, we've pushed 2.0.3, 2.0.4 and 2.0.5 to fix the most important issues and regressions reported.

However, we also added a few features notably:

  • Support for HTTP proxies,
  • Support for HTTPS self-signed certificates,
  • Subtitles style modification in preferences,
  • Improvements for SMB browsing,
  • Support for more ARMv8 devices.

And we also added, in the main branch, some modifications about preferences, and adding new ones.

iOS

The iOS buildsystem was modified to support full cocoapod building, so you can compile just the application, without compiling VLC and libVLC.

This important change introduced quite a bit of cleaning of the code and of the project. :D

WinRT

On WinRT, we've prepared a MediaCenter Mode for the Xbox 1.

We fixed numerous interface issues and crashes, that were reported in 2.0.1.

A few fixes where pushed also to address issues happening with specific themes or specific resolutions in responsive mode.

That's all for those weeks! There is probably a bit more I forgot about, but you should have the important parts.

See you soon!

Last weeks in VideoLAN - 49

49th VideoLAN report

So, after two busy weeks, you can get a new weekly report about the VLC and VideoLAN communities!

Releases

Android

10 days ago, we released VLC for Android 2.0.

After a long period of development, we're finally at a release that supports more features than the old 0.9.x versions and the 1.7.x versions.

Video List

UWP

And last week, we released the new VLC for Windows 10, numbered 2.0 too.

It is a continuation of the work we did for WinRT, the kickstarter, focused on Windows 8.1, Windows Phone 8.1 and Windows RT.

The new application should supersede the old one.

Features

VLC

In the last 2 weeks, we improved the ChromeCast support, notably to work on transmitting the pause status and the title between the device and VLC, and we also changed the interface to scan for devices, since it was a bit confusing.

We added support for some uncompressed video format inside MKV, for the AlbumArtist meta-tag inside mp4 and we now support more MicroDVD subtitles styles.

Our new Kwallet module was transitioned from using libKwallet to DBus. This will be better to support both Qt4 and Qt5 applications with libVLC, because those versions are not ABI compatible.

The core gained a new stream FIFO API, with functions like vlc_stream_fifo_New, vlc_stream_fifo_Queue, vlc_stream_fifo_Write and vlc_stream_fifo_Close.
This change, in addition to the new chained_demux implementation in the core, removes the need for stream_Demux (now removed).

We also improved the security when loading of DLLs on Windows.

And for Android, AudioTrack DTS pass-through was implemented.

Finally, numerous fixes were pushed, notably for Direct3D11, our contribs, some in the core, youtube playback regressions, the Mac OS interface, crashes for MMDevice device, and for the MediaCodec decoders. And more that I forget...

Android

As I said, we released 2.0, and we also pushed 2.0.1 and 2.0.2 to fix the most important crashes reported.

WinRT

Same, we released 2.0, the first beta version of the UWP application. Fixup releases are coming soon!

iOS

On iOS, we pushed the promised update and we had a few refactoring, notably on the network login view.

libbluray

The libbluray code was modified to support 8.3 filenames, like in AVCHD directories we see in camcorders. This is the first step for full AVCHD support in VLC :)

That's all for those weeks! Not too bad :)

See you soon!

This week in VideoLAN - 48

48th VideoLAN report

Another week passes by and here is a new weekly report about the VLC and VideoLAN communities!

Features

VLC

Like our previous week, most of the work was focused on stabilizing features and bug fixing. Therefore, the changelog will be quite short too. :D

A new type of module was introduced, named demux filter; they are used to filter or intercept demuxer controls commands and demuxing.
The first use case of this type of module is the ChromeCast demux filter, to show the correct playback time when using the ChromeCast, that we merged this week too.

Some work was done to support the next version of macOS: Sierra. This notably concerns the input capture plugin.
Also, on MacOS X, the interface for renderers was merged.

The 2 SPDIF modules, ac3 and dts have been merged into a single one.

In the core, we've seen fixes for UTF-8 support, media discoverers API, libVLC parsing calls memleaks, tests, buildsystem and Windows threads.

Android

On Android, we've done the same kind of bugfixing as last week, and we have released 2.0.0 RC4 and pushed it on the store.

Not many issues are remaining for the release, now.

WinRT/UWP

On WinRT, we are also in the bugfixing phase, with a lot of commits to make sure the application does not crash too much.

Indeed, we're closing to an open beta release, but the number of crashes was still too high, especially when using the application for a long time.

We also fixed the background audio support on Windows 10 Mobile phones; and reworked the thumbnailer.

The application should be opened in beta to everyone soon.

iOS

The iOS application got a few fixes, notably for remote playlists and XDCAM support and we're pushing an update named 2.7.8 this week.

That's it for this week, stay tuned!

This week in VideoLAN - 47

47th VideoLAN report

A new week, a new weekly report about the VLC and VideoLAN communities!

Features

VLC

After an intense previous week, most of the work was focused on stabilizing features and bug fixing. Therefore, the changelog will be quite short. :D

In the core, we pushed multiple fixes for preparsing and input slaves and we added tests for those features. We also fixed issues in the media discoverer code.

On the modules side, we notably had fixes in the bluray, the oss, the adaptive streaming, the OS X video output and the UPnP modules.

Finally, we added an OpenGL provider for Windows, in order to add back the support for OpenGL visualisations, like projectM.

Android

Same story on Android, we focused on fixing issues, to prepare the release 2.0.

We pushed RC2 and RC3 on the store to fix crashes reported by the first set of devices where the application was pushed.

We redesigned a bit the speed setting, as requested in our Google+ group.

WinRT

On WinRT, the focus was also on bug fixing and preparing a release. The more important bugs were on Cortana integration and metadata management.

However, we also activated the downloading of subtitles from Internet, notably the OpenSubtitles website.

We also improved the browsing of local network servers, similar to what we did to the Android port.

That's it for this week, stay tuned!
