Support AV1 RTMP streaming

Describe the bug
While using local stream as input to do SVT-HEVC transcoding with ffmpeg, and config output as streaming with DASH, then use VLC or FFPLAY to playback the generated segment file index.mpd, we found video freeze after playing some time with VLC or FFPLAY.

We tried 3 times with VLC about this issue：
1st time used about 3 minutes
2nd time used about 5 minutes
3rd time used about 5+ hours

While the issue happened, both VLC and FFPLAY print error info in terminal, please see below pictures for detail.
VLC error info:

FFPLAY error info:

To Reproduce
Steps to reproduce the behavior:

1. Setup the test environment based on the guide.
2. Run below command line to do transcoding to SVT-HEVC (make sure add parameter "-stream_loop -1" to loop input stream):
   ffmpeg -re -stream_loop -1 -i Nature.mp4 -s 40962160 -c:a copy -c:v libsvt_hevc -b:v 20M -f flv rtmp://nginx_ip1/dash/4kCamera -s 40962160 -c:a copy -c:v libsvt_hevc -f flv rtmp://nginx_ip2/dash/2kCamera
3. Run below command to use VLC and FFPLAY playback:
   ffplay http://host_ip:port_ID/dash/4kCamera/index.mpd
   vlc http://host_ip:port_ID/dash/4kCamera/index.mpd

Expected behavior
Video playback should be smooth, no freeze and no error.

Bug description
The manifest index.mpd generated by the transcoding process does not allow automatic switching in resolutions because it is badly formed.
This issue is written after making sure #10 and #19 and #26 didn't cover it.

To Reproduce
Steps to reproduce the behavior:

1. Set up the vod transcode service (example)
2. Start a DASH stream to begin the transcoding process (from the web GUI, for instance)
3. On the deployment server (host), inspect the generated manifest. From the repository folder : less volume/dash/<stream_name>/index.mpd

Expected behavior
The manifest should contain one single <AdaptationSet>...</AdaptationSet> tag with the attribute contentType="video", containing all the <Representation>...</Representation> tags, each corresponding to a resolution. This is not the case as it has one <AdaptationSet>...</AdaptationSet> per resolution, each containing a single <Representation>...</Representation>. This results in not being able to switch automatically when ABR logic would need it.

You can test in depth the ABR behaviour with this standard DASH player. Give it a URL formed this way: https://<host IP>/dash/<stream_name>/index.mpd.

Screenshots

Server:

• OS: Ubuntu Server 18.04
• Configuration process: Described here
• Version: 63e4b85

Additional context
We forked your project for a small college research on edge-computing (more info). Solving this issue is a matter of efficiency as we need to correct the manifest by hand every time.

Describe the bug
Using 1 xcode server + 1 cdn server to do H264/MPEG2 transcoding to x265, the transcoding is ok and the output file index.m3u8 or index.mpd is also generated with normal size, but while using ffplay or VLC to play the x265 clips with HLS or DASH, there will be no output in screen and error log is printed by ffplay.

NOTE: If streaming output x265 stream with RTMP during transcoding, then use ffplay to playback with RTMP, the output is ok but has about 15s delay; If play with VLC also no output in screen.

To Reproduce
Steps to reproduce the behavior:

1. Run transcode command in xcode server: ffmpeg -re -stream_loop -1 -i /var/www/Mpeg2_1080.m2v -c:v libx265 -s 4096x2160 -f flv rtmp://ngnix_id:port_id/hls/4kCamera
2. Run ffplay (with HEVC enabled patch) command in another Linux machine:
   ffplay http://host_ip:port_id/hls/4kCamera/index.m3u8 or play with VLC on your windows PC.

Expected behavior
Video should be played smoothly with FFPLAY or VLC, no error and no delay.

Use HTTP-FLV to delivery live stream in flv format over HTTP, which could traverse firewall and meanwhile provide lower latency than DASH/HLS. It's a very common in China.

[Issue Description]
When use IP camera stream as input to do SVT-HEVC transcoding with ffmpeg, the output stream can’t be played after about three minutes of transcoding.
The error message of VLC is "Failed reading https://host IP/hls/4kStream/0.ts: HTTP/1.1 404 Not Found", please refer to VCL.png attach file for
details.
After checking index.m3u8 file, it was found that Segment ts files deletion speed is faster than index.m3u8 updated speed.Please refer to ts.png attach file for details.
The issue only can't be reproduced on E3 server and VCA2 server.

[Reproduce Steps]

1. Setup 1toN Xcode Sample test environment based on the guide (CDN_Transcode_Sample_Getting_Started_Guide.md).
2. Run below command line to do transcoding:
   ffmpeg -i rtsp://admin:password@IP cameras/101 -s 40962160 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/4kStream -s 20481024 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/2kStream -s 19201080 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/1080Stream -s 1080720 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/720Stream -s 720480 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/480Stream -s 320240 -c:a copy -c:v libsvt_hevc -f flv rtmp://CDN IP/hls/240Stream
3. Run below command to use VLC playback after about three minutes.
   vlc https://host IP/hls/4kStream/index.m3u8
4. Check Segment ts files and index.m3u8 file under /var/www/hls/4kStream

[Actual Phenomenon]

1. The output stream can’t be played.
2. Segment ts files deletion speed is faster than index.m3u8 updated speed.

It is possoble that the live pod will be killed when the encoder is acv and the resolution is hd720 or hd1080.

Hello! I found this project very interesting and useful!

Could it be used in production environments?

Describe the bug
Output stream of CDN-Transcoding sample only have one Representation (one video) in AdaptationSet of DASH if use ffmpeg rtmp sending the stream to Nginx server for Dash segment.

To Reproduce

1. complete 1toN transcoding with Nignx docker setup according to readme.
   start 1: xeon-ubuntu1804-ffmpeg:1.0 docker to complete transcoding task.
   start 2: xeon-ubuntu1804-nginx-rtmp:1.0 docker to complete Dash segment.

2. input streaming as:
   root@f1ac23ac6f74:/media/_System_Validation# ffmpeg -re -i /media/_System_Validation/mp4_h264aac/h264_1920x1080_b@40_2397_8225kbps_cbr_aac_lc_256kbps_48000_hd_the_living_see_2mn48s.mp4 -c:v copy -f flv rtmp://192.168.31.32/stream/xcode

3. Xcode server to do transcoding and rtmp upstreaming to nginx server:
   transcoding (xeon-ubuntu1804-ffmpeg:1.0 docker) -> DASH segement MPD file (xeon-ubuntu1804-nginx-rtmp:1.0 docker )
   command as:
   ffmpeg -i rtmp://192.168.31.32/stream/xcode -c:a copy -c:v libsvt_hevc -f flv rtmp://192.168.31.31/dash/hevc

4. only have one video in MPD file. (xeon-ubuntu1804-nginx-rtmp:1.0 docker )
   only one stream is supported in flv format.

Expected behavior
need multi-video in DASH MPD with different resolution and bitrate to adapt different network situation.
Additional context
just link use ffmpeg command line to achieve multi-video :

3. Run below command to use VLC and FFPLAY playback:
   http://host IP/hls/Intelligent_1920x1080/index.m3u8
   http://host IP/hls/Intelligent_1280x720/index.m3u8

Support manually set the CPU and Memory resource

Live ulr play failure, and the live pod‘s cache files would be deleted unexpected.

To Reproduce

1. Use ffmpeg upstreaming stream as input media content to xcode server and do transcoding, command line such as:

ffmpeg -re -i /media/_System_Validation/mp4_h264aac/h264_1920x1080_b@40_2397_8225kbps_cbr_aac_lc_256kbps_48000_hd_the_living_see_2mn48s.mp4 -c:v copy -f flv rtmp://192.168.31.32/stream/xcode

2. in Xcode server, use ffmpeg to do transcoding and rtmp streaming to nginx server which can transformat DASH/HLS segments, command line such as:

 ffmpeg -i rtmp://192.168.31.32/stream/xcode -s 4096*2160 -c:a copy -c:v libsvt_hevc -preset 10 -maxrate 4000000 -r 30 -f flv rtmp://192.168.31.31/dash/

3. ffmpeg Xcode server can't exit transcoding even if input rtmp streaming is finishing broadcasting.

Expected behavior
In transcoding server, ffmpeg should exit if the input streaming was finished broadcasting.

The gui tool will unexpected quit when it is used.

[Issue Description]
The time format display incorrect when first time playing dash stream in VOD mode. After the first transcoding is completed, the time format will be normal.
On Chrome browser, the time shows “-14:-8”.
On Firefox browser, the time shows “2501999792983:36:31”.
On Microsoft Edge, the time shows “596523:1”.

[Reproduce Steps]

1. Setup 1toN Xcode Sample test environment based on the guide (CDN_Transcode_Sample_Getting_Started_Guide.md).
2. Use the following commands to start docker-compose service
   make start_docker_compose
3. Enter VOD web page via https://HostIP with Chrome, Firefox or Microsoft Edge browser
4. Play dash stream and check the time format.
5. Please refer to attach files for autal phenomenon

Upload UGC video clip via HTTP and then do offline transcode in HLS & DASH format

Requirements of feature:

1. During make start_kubernets Customer has ability to use default config file or specify custom config file for transcoding
   • Configuration file is used to configure encode/transcode session
2. Should be supported for both VOD and Transcode sessions
3. Config file to support arbitrary number of outputs per Input stream
4. Configuration file to support configuration of, but not limited to, following Encoder configurations
   • Codec
   • Preset
   • Output resolution
   • GOP Size
   • GOP configuration(LD/RA/B Pyramid etc…)
   • Bitrate rate controls
   • HRD configuration
   • Extra field where string is concatenated at end of encoder command so additional options can be passed to encoder
