Roku Developer Program

If I use AWS Elastic Transcoder it creates compatible video with the Roku, however when I use the following the videos refuse to play, even though they will play fine in VLC player.

I am using this as a guide: https://www.drupal.org/forum/support/po ... aybe-8-too

-hls_time 10 -hls_key_info_file keyinfo -hls_list_size 0 -hls_wrap 0 -hls_allow_cache 0 -start_number 1 -segment_format mpegts -copyts

Any thoughts to make it work properly?

It can be a number of things, like where are the files being served and are the proper headers set, or is CORS blocking the callback due to same-origin policy?
Keep in mind when you click on a video in VLC that is a direct link opposed to streaming it to the ROKU. 

It could also be maybe the audio or video or both codecs are not compatible. 

Also, is the end file an m3u8 or is it a ts and if so what is the streamFormat set to? I have found with containers that include or point to ts files that using streamFormat="auto" works best.
Even with the ROKU stream tester none of the video format options will work unless auto is set for the format. It's really odd. 

That would be the main reasons as to why. I would like to ask why are you using Drupal instructions when you should be going with Apples instructions and guidelines. Which in that regards it could be the ffmpeg settings. Do you know if it saves the file as utf-8 encoded without BOM?

There is a free software called Handbrake which has long been around and they have settings based on ROKU outputs and its quite fast, might be your best solution to be honest with you.

I hope this has helped some and if you have questions feel free to ask.

It's not a CORS issue, I just played back video that was created from AWS Elastic Transcoder and it worked fine, so its not a connection issue.

Are you seeing any errors in the debugger?

[bounce]

none it is just stuck. I'm pretty baffled by it.

Here is what I'm using and works fine:

-vcodec copy -codec:a aac -f hls -hls_flags delete_segments

This works for converting a rtsp stream that is h.264 encoded.
Here is an example:

ffmpeg -loglevel error -thread_queue_size 512 -rtsp_transport +udp+tcp -rtsp_flags prefer_tcp -i rtsp://login:pass@192.168.1.64:554/Streaming/Channels/101?transportmode=unicast&profile=Profile_1 -vcodec copy -codec:a aac -f hls -hls_flags delete_segments /dev/shm/ggzEtQzhOE.m3u8

[bounce]

Thanks for sharing, I'm not using RTMP, so would it translate pretty well with something say a mp4, h264 type file?

I'm sharing a completed file example of what FFMPEG is passed and why the file fails to load in Roku. Its cleaned up a little to help you understand what is happening. Should I eliminate a parameter to make it compatible?

ffmpeg -re -i file.mov -y -threads 4 -preset ultrafast -c:a aac -strict -2 -b:a 64k -ac -c:v libx264 -x264opts keyint=90:min-keyint=90 -s 640x360 -b:v 600k 
-force_key_frames 90 -profile:v baseline -level 3.0 -hls_time 10 -hls_key_info_file key_info -hls_list_size 0 -hls_wrap 0 -hls_allow_cache 0 
-start_number 1 -segment_format mpegts -copyts file-stream-low.m3u8

I'm not very knowledgeable in how to make ffmpeg work, I found my solution after searching a lot and testing what other people are using.
If your file is h.264, then yes, using 

-vcodec copy -codec:a aac -f hls -hls_flags delete_segments file-stream.m3u8

should work fine.

Try something like 

ffmpeg -re -i h264file.mp4 -vcodec copy -codec:a aac -f hls -hls_flags delete_segments file-stream.m3u8

Note, I didn't try that command, I'm just guessing that is how it should look like.

I'm still having quite a fit with getting this working. What is even more frustrating is that Roku does not spit out an error, it just quits loading.

Can anybody else chime in on getting FFMPEG to work creating compliant files for Roku. Here is the Bash Script I'm using if it will help.

#!/bin/bash

#generate encoding key
keyFile="$name.key"
#save encoding key to file

#if we are successfully adding SSL, then http should be changed into https

Have you tried it without the encryption? Try using the first "OUTPUT_HLS=" line instead of the second and see if it works.
