Deinterlacing - MX Player

I am using MX Player on Android. In Settings > Decoder > General, there is an option to enable Deinterlace. However, there is a comment that "Currently deinterlacing woks only with SW decoder".
Does this mean that deinterlacing happens along with the decode and hence, HW decoder's can't support it? If deinterlacing is outside of decode, why isn't the same enabled for HW decoders too?

If I am not wrong, In HW mode decoding will be done through internal modules. Hence, It can't be implemented.
In SW mode decoding will be done through optimised ffmpeg libraries included with mxplayer in which it is possible to pass the respective commands.
That's why it's is possible only in SW mode.

Exactly as ktsamy has said. HW mode passes the decoding to the system hardware, so MX Player can't implement deinterlacing. SW uses MX Player's build of ffmpeg, so it can deinterlace here.

[Feature Request] .ts file is not HW-accelerated but repacked to MKV is

Hello,
When I try to play .ts file (e.g. HBO HD movie) recorded using DVB-C set-top box, MXPlayer uses SW mode and playback looks like a slideshow.
So I have repacked the same movie to MKV container using mkvmerge and followed the advice from this forum to configure MXPlayer to use HW acceleration for video and SW mode using custom codec for audio (for AC3 decoding). Playback is perfectly smooth in this case, because MXPlayer uses HW acceleration.
The original TS file contains:
- H264 1080i PAL 50fps track
- 1st AC3 audio track
- 2nd AC3 audio track
- 1st DVB subtitle track
- 2nd DVB subtitle track
The repacked MKV file contains:
- the same H264 track (w/o recoding)
- the same 1st AC3 audio track (w/o recoding)
(mkvmerge cannot convert DVB subtitles, so in MKV file the subtitle track is missing)
I have the Acer Iconia A1 810 tablet.
Repacking to MKV is an option to play my recordings smoothly, but I'd like to play the original TS files from SMB share, because my archive is full of such TS files. Repacking is hard and slow and additionally it'd throwed the subtitles away.
Please, is it possible to modify MXPlayer so it can play also the TS files in HW accelerated mode?
Thank you in advance!
I doubt it, because the ts container can contain so much more incompatible formats and as you probably know, AC3 for instance is not hardware supported on most devices. You cant go and force hardware decoding for something that might-half-work, but you always have the option to select your decoder and try. I'm afraid you'll just have to accept that there's some things your hardware can't decode.
Note that the smooth playback is not a problem in my case. Repacked in MKV container, my hardware plays both the mentioned tracks (H264+AC3) smoothly.
What I ask the MXPlayer team for, is to enable the same MXPlayer behavior for the original TS container file containing the same tracks (H264/AC3).
In my opinion, the MKV container is the same case as the TS container. MKV file can also contain almost anything.
I've thought that the decision to use (or not to use) HW acceleration for a video track should come after a splitter, on the basis of the video format and should not be derived from a container file format.
Hmm, that is odd. Sorry I assumed the AC3 track would've been incompatible, as it is with many androids. I always thought MX Player did decide on HW acceleration independent of containers. I can only guess some track contained in the .ts is incompatible.
But have your tried forcing HW playback (or HW+) on the .ts file yet? You can select this in the top right while a video is playing.
I thought that HW support of different containers depended on the device. Not sure.
I would think that when you select HW, it not only passes the decoding, but also the container splitting, to the hardware, which is my guess at why HW won't support different containers since the hardware doesn't know how to split the container.
@bleu8888 could you provide some insight into this?

Thank you CDB-Man and Logic_ for your thoughts.
In MX Player, it is possible to use HW decoder for a video track in parallel (and in sync) with SW decoder for an audio track. That is why I hope, that a container-splitting can be done independently on choice which decoder will be used for the given track.
My understnading is that splitting is done by whatever is set as the video decoder in MX. Audio decoder just receives the audio stream from whatever splitter is used. It's not that SW audio runs "in parallel" with HW video per se; SW or HW audio just receives an audio stream from whatever is used as the container splitter.
Sorry, my previous post was probably somewhat misleading.
It was reaction to your post:

I wanted to say, that from the fact, that video can be independently decoded by HW and audio by SW, I presume, that splitting can also be done independently - by SW - while maintaining the players ability to pass video track decoding to HW.
Hi KodloN,
Did you try hw+ decoder? hw decoder is just stock decoder which has no chance to be improved at all.
If you it still does not work with hw+ decoder, please send me (to [email protected]) a sample .ts file that cannot be played with hw+ decoder.
Thanks

Hi bleu8888,
Yes, I've tried hw+ decoder, below are results:
1) The original TS file (HBO_HD recording)
SW decoder only. Trying to switch to HW or HW+ decoder falls back to SW with error message "Cannot play this video with H/W(+) decoder".
2) TS file in which the DVB subtitle track and the Czech audio track were removed (repacked by DVBViewer-TSPlayer)
HW+ decoder is functional, but playback is sluggish on my Acer Iconia Tab A1-810 (similar performance as SW decoder playback)
HW decoder cannot play this video.
3) MKV file created from the original TS file using mkvmerge
HW decoder is functional, perfect smooth playback
HW+ decoder cannot play this video
I will send you a link to all three files to the specified email.
Thank you in advance!
Hi,
Would you try latest test build from following link?
.ts hw+ playback is improved in this test build but I'm not sure your issue is fixed because this issue looks like happening only on MediaTek platforms and I do not have device having MediaTek playform.
(Please note that hw playback is not changed though)
https://sites.google.com/site/mxvpen/translation/test-build
BTW, DVB subtitle positioning issue is also fixed.
Feedback will be appreacited !
Thanks

[Q] Cannot play HEVC files on my RK3288

Hi everyone,
Hoping someone can help
I just bought an Android TV Box featuring the RK3288 SoC and I cannot get MX Player to play the standard HEVC's (Sintel, Kazu, Tears of Steel etc).
They are just resulting in a black screen with audio only using the HW decoder, I tried activating the HW+ decoder but it says it's not available.
Any ideas? The files play fine in HW mode on Kodi.
Thanks,
Steve
I dont know about tv box. HW is not supported for HEVC. SW Decoder can play HEVC in my mobile. Have you switch to sw decoder?
SW is too stuttery to be of any use. The weird thing is I know that others can playback HEVC on theis SoC on MX Player so there is obviously something I'm missing...
It depends.
H/W decoder uses android's mediaplayer API to play the video. In short it will be similar to stock player. Some devices natively support HEVC. So, they can play HEVC in H/W decoder.
In some cases, the SOC may support HEVC decoding. But, the OEM may disable it to avoid patent issue or to save licensing fees.
If it's not natively supported, S/W decoder is the only option. But, in this entire decoding will be done on CPU. So, the performance will be purely depends on CPU power. It may be laggy on HEVC/HD videos.

[Q] [REQUEST] Alternative codecs combinations

Is it possible to create a wider codecs combinations for decoding posibilitie of MX?
For example: HW video with HW+ audio
Or create separate codecs settings.
On my Amlogic S812 there is problem with decoding MKV video file with HW+ decoder, video is twitching (or somewhat, I can't more correctly describe this effect) with 3 to 5 secs. Interval. With HW it's OK , but no sound.
Thank you for your help.

Just enable SW audio from audio track selection. You will get HW video & SW audio.

I allready tried it. But sometimes I got double sounding on AAC codecs while SW audio was set permanently.
Sets SW audio separetly for each MKV is not so comfortable for my opinion.
Is there some way exists to use only SW audio for all files, I think MX does not block HW audio if track was supported by HW in this mode, or it's a bug?

I can't reproduce the double audio issue.
Can you collect the logs immediately after playing the file which leads to the double audio issue?
If it's possible kindly share a sample video.

Is there a way to do the opposite of that? I need SW video & HW audio.
When I play test files directly from the device, I can use HW decoder and they play flawlessly. But when I play files from my NAS with the HW decoder, MX Player buffers. If I use the SW decoder playback is smooth, but the audio is always downmixed to stereo. I have tried both the default and custom software codecs with the same results.
Also MX Player informs me that HW+ is not available on my device, if that make a difference in the decoder options I have selected? I have tried "HW+ audio on SW video" with "SW decoder (network)" but MX Player still shows playback to be HW with the results mentioned above.

MX player not supporting hevc h265 and hw+ not working with h264 and h263 1080p video

Please create support for hevc(h265) which highly effective and efficient codec video format for video and has gain lots of popularity. There is also issue for hw+ not supporting and compatible with h264 and h263.

It depends on the device. Most of the modern devices can play HEVC Main profile videos in the HW & HW+ decoders. We will be able to assist you better if you can share a bug report from the MX Player help menu.
IN general, HW & HW+ decoders make use of the hardware acceleration provided by your device chipset. If the chipset doesn't support hardware acceleration of HEVC or it is not implemented by the manufacturer, there is no way to play the same in the HW or HW+ decoder. It is your hardware limitation. The only way to play is to use SW decoders. But, it may lag if your CPU is not powerful enough to handle the decoding load.

Can you analyze my report file?
I think most devices now support h264 decoding. I know for sure my Fire Stick 4k supports 264 and 265 decoding by hardware, and it starts playback fine....but then after a while it jumps from HW to HW+ to SW, saying not supported.
I'm very happy to see that MX Player now streams 1080p HEVC 10-bit MKV flawlessly to my Samsung Galaxy Tab A 10.1 2016! I have literally tried to get it to work for years. HW+ option did not bring better results (stutters and hickups), heck, even transcoding from my Synology Disk Station was a pain in the a. I am curious to know what you changed in the recent version 1.10.51 (I will archive it forever and keep it in my heart) or if I was just too stupid or my device was too slow.

HW+ Audio codecs should they all be selected?

Hello.
I have installed the latest MX player and the latest codecs all in one.
By default all the HW+ audio codecs are not selected in the decoder settings. This includes AAC and EAC3.
Should these all be selected?
All the HW+ video codecs are selected by default except for H264 10bit.
Thank you

Hi @lukehansford,
We would like to let you know that HW+ Audio is still in an experimental state and suggest you keep it in disabled. Moreover, the audio decoders shipped with most of the devices are software-based. So, enabling this may not provide any advantage in most of the devices.
