h264_omx instead of x264

Hello,

 

I have created an Emby addon for LibreELEC (LE), which seems to run fine on x86_64.

 

On Raspberry Pi (RPi) however, transcoding does not work properly, because neither ffmpeg fetched by Emby, nor ffmpeg provided by LE are adequate.

 

In order to address this problem, I have built an version of ffmpeg for RPi enabled to encode via OpenMAX IL for Raspberry Pi (h264_omx), which is capable of transcoding 720p at 50+ fps.

 

Is it possible to configure Emby to use h264_omx, rather than x264, for transcoding? If so, how?

LE is currently running Emby version 3.0.5972.0, but this can change if it improves transcoding.

 

Thank you in advance for your assistance,

@

Well yes, but before i write the code for that, it would faster for you to play something with x264, in Chrome for example, then grab the command line from the transcoding log. From there you can research how much will need to be changed by testing out the command lines on your own. You'll need to customize the in-app bitrate setting to a low value to force transcoding. If you can do that leg work, then I can look at adding proper support for it.

I started with a command found in the Emby logs:

/storage/downloads/ffmpeg+/ffmpeg+ -fflags +genpts -i file:"/storage/downloads/test720p.mp4" -map_metadata -1 -threads 0 -sn -codec:v:0 libx264 -pix_fmt yuv420p -preset superfast -crf 23 -b:v 15242310 -maxrate 15242310 -bufsize 30484620 -vsync vfr -profile:v high -level 41 -force_key_frames "expr:gte(t,n_forced*3)" -sc_threshold 0 -codec:a:0 aac -strict experimental -ac 6 -ab 320000 -af "adelay=1,aresample=async=1" -hls_time 3 -start_number 0 -hls_list_size 0 -hls_base_url "hls/44802c6446da28c773b15182d74143b1/" -y "/storage/.kodi/userdata/addon_data/service.emby/transcoding-temp/44802c6446da28c773b15182d74143b1.m3u8"

When I changed libx264 by h264_omx, I got the following errors:

Codec AVOption crf (Select the quality for constant quality mode) specified for output file #0 (/storage/.kodi/userdata/addon_data/service.emby/transcoding-temp/44802c6446da28c773b15182d74143b1.m3u8) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption preset (Set the encoding preset (cf. x264 --fullhelp)) specified for output file #0 (/storage/.kodi/userdata/addon_data/service.emby/transcoding-temp/44802c6446da28c773b15182d74143b1.m3u8) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
[h264_omx @ 0x301a430] [Eval @ 0x7e93e4cc] Undefined constant or missing '(' in 'high'
[h264_omx @ 0x301a430] Unable to parse option value "high"
[h264_omx @ 0x301a430] Error setting option profile to value high.

So I removed:

-crf 23
-preset superfast
-profile:v high

Then, it ran:

frame=  854 fps= 27 q=-0.0 Lsize=N/A time=00:00:35.61 bitrate=N/A speed=1.13x

In summary, a command suitable for h264_omx could be:

/storage/downloads/ffmpeg+/ffmpeg+ -fflags +genpts -i file:"/storage/downloads/test720p.mp4" -map_metadata -1 -threads 0 -sn -codec:v:0 h264_omx -pix_fmt yuv420p -b:v 15242310 -maxrate 15242310 -bufsize 30484620 -vsync vfr -level 41 -force_key_frames "expr:gte(t,n_forced*3)" -sc_threshold 0 -codec:a:0 aac -strict experimental -ac 6 -ab 320000 -af "adelay=1,aresample=async=1" -hls_time 3 -start_number 0 -hls_list_size 0 -hls_base_url "hls/44802c6446da28c773b15182d74143b1/" -y "/storage/.kodi/userdata/addon_data/service.emby/transcoding-temp/44802c6446da28c773b15182d74143b1.m3u8"

I hope this will help you fit h264_omx into Emby.

Thank you in advance

Well can you set if it has equivalents for those things that you took out? We probably don't just want to leave it all at default.

does h264_omx have any documentation? for now we can use the information here as a starting point. I will add h264_omx to the UI for hardware encoding selection. Thanks!

Hello Luke!

 

I have updated Emby for LibreELEC to version 3.0.5985. Transcoding works, except that the transcoded stream is also displayed at the server, which is neither expected, nor desired. This is an issue with ffmpeg, and I have therefore opened a bug report at ffmpeg. I will keep you updated on this thread.

Hello Luke!

 

I just wanted you to know that I am still working on this, but that I have been busy with my family, other projects and works.

 

I have noticed that with version 3.0.6030, the circle keeps spinning when you save transcoding settings. There is not message that settings have been saved. The settings are nevertheless saved and operational.

 

Hopefully, I will soon be able to solve the ffmpeg issue.

I have noticed the same when using Chrome and Win10 (not checked any other browsers) on Emby 3.0.6400.0.

 

That said, I just started messing with the hardware transcoding for my Roku2 (mostly "handbraked" 1080p content). I have an AMD A6-6400K (I run it on Linux/unRaid). Will OMX work for me (or is it really just for RaspPI), how can I test it out and see if it is doing anything different from just "none" for transcoding?

Hello!

 

Thank You very much for such nice work, emby is great!

 

And now my problem:

 

I'm using Raspberry Pi 3 with jessie lite, as headless server. Unfortunately, I can't force it to use h264_omx properly. With x264 works good (as possible on RPi3). I compiled ffmpeg with configuration:

./configure --arch=armel --target-os=linux --enable-gpl --enable-libx264 --enable-libmp3lame --enable-omx-rpi --disable-debug --enable-version3 --enable-nonfree

When I choose in webapp to use hardware acceleration (Open MAX), I got lot of:

[mpegts @ 0x18de100] H.264 bitstream error, startcode missing, size 0

Is it any problem with ffmpeg compilation configuration? Is it proper? Or should I change something in /etc/emby-server.conf ?

 

Whole log from transcoding is attached.

 

Thank you in advance!

I'm not sure about this one. It looks like something particular to h264_omx but I'm not sure what it is. If someone can help hunt down the encoding parameters that need to be changed, I'm happy to make the changes.

Thanks anyway!

 

I will try to invastigate this further... unfortunately, I started "fun with linux" about 2 weeks ago... when I bought RPi... sooo it can take some time... @@awiouy wrote, that has it working in LibreELEC, mayby he could suggest something?

May I ask how you compiled ffmpeg with h264_omx

kk.. I will check it out...

Compilation of ffmpeg almost complete :)

 

Had to re-install my emby server

I overclocked my Pi and I burned the crust :)

....system froze in the middle of a disk update.. decided not to take a chance in repairing the file system and just re-installed everything, it was a clean install anyway,

 

I will report my results

 

Kind regards

well...
 
well....well...well...
 
After a few trials and errors... i have a customized ffmpeg binary compiled.
my own tests show REMARKABLE speed increases..  there are evolutionary speed increases, and then there is this:
 
time sudo ./ffmpeg -i ../Sample.mkv -c:v h264_omx -c:a copy -b:v 1500k test-omx.mp4
,,,
real    0m12.032s
user    0m26.920s
sys     0m1.510s
 
time sudo ./ffmpeg -i ../Sample.mkv -c:v h264 -c:a copy -b:v 1500k test-264.mp4

real    1m23.900s
user    5m3.540s
sys     0m2.810s
 
 

pi@avcenter:~/ffmpeg $ ls -lsh test*mp4
9.1M -rw-r--r-- 1 root root 9.1M Apr 24 21:57 test-264.mp4
8.2M -rw-r--r-- 1 root root 8.2M Apr 24 21:56 test-omx.mp4
pi@avcenter:~/ffmpeg $
 

Note1: file sizes are different.. but I played both files.. they both seemed fine.
Note2: 12s vs 82 secs... that is a HUGE improvement. 
 

 
 
However..
The transcoding in emby works WITHOUT enabling OMX optimizations in the emby web interface.
With it enabled, the ffmpeg process fails... and no movie is displayed.
Logs show that ffmpeg was called, and I see no errors... but maybe I am missing something.
 
I would love to see it fixed.. anybody else seen this?  Anybody successfully using an OMX compiled ffmpeg binary?
