HLS streams
Hi! I would first like to congratulate you for the great library! I'm setting up a Web radio and I noticed that several URL's don't work. Many of them stream over HLS (eg: "https://eldoradolive02.akamaized.net/hls/live/2043453/eldorado/master.m3u8"). Is this format not supported? Thanks!
m3u8 playlists are a special challenge. Some simple ones can be played like http://stream.revma.ihrhls.com/zc4435/hls.m3u8 In principle, individual streams (playing only a few seconds) are summarized in the playlist. Once the individual streams have been played, the playlist is often outdated and a new one has to be fetched. The only solution I have is to cut the existing connection and establish a new one. Especially with encrypted connections, if it is too long (approx. 2 seconds) in the current stream, this leads to dropouts. If anyone is reading this and knows a solution, please post it here.
My project is here: https://github.com/renatoianhez/Lolin32-radio In the code, I inform which radio stations have glitches with a "GL+"
https://github.com/Yokohama-Miyazawa/M5HLSPlayer
It would be nice if this library here had this addendum!
Yes, HLS integration would be a good thing. I had already started with it, very simple m3u8 streams are already running. This is only a small part of all possible streams. The linked project is extensive and it takes some time to understand exactly how it works. The TS part with the PAT/PMT tables is interesting.
Thank you so much, In India, ALL INDIA RADIO (AIR) nowadays streams its channels with m3U8. like https://air.pc.cdn.bitgravity.com/air/live/pbaudio001/playlist.m3u8 all are in .ts file format.
.ts format links not working https://air.pc.cdn.bitgravity.com/air/live/pbaudio001/playlist.m3u8 thankyou for your wonderful work..

I still have some 'normal' m3u8 streams that aren't working yet, I'll do that first. TS is coming soon, I still have some testing to do. I can't unpack gzip compressed responses from server.
thank you so much for bringing .ts format live.. its playing now, but, while changing the stream files there is small glitch of noise. and after streaming one or two files we can see "slow stream, dropouts are possible".
Some links are unable to play as below.. "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MRETRO_Auto.m3u8" "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MNINTS_Auto.m3u8" "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MEETHI_Auto.m3u8"
this will be your roaring update.. thank you so much. I am happy to use your work.
Not work with Eldorado FM: https://eldoradolive02.akamaized.net/hls/live/2043453/eldorado/master.m3u8
There is still a lot to do, this is only a partial success, but now I know how to correctly unpack TS packets without the AAC decoder complaining. I have a list of URLs that don't work at all or get into an infinite loop and then quit.
To make better use of the flash memory I recommend the huge_app.cvs partition table, and to reduce dropouts the DMA can be set as high as possible, in the constructor m_i2s_config.dma_buf_count set from 14 to 20 .
line no 2228 if(m_f_ts) m_m3u8_timeStamp = millis() + m_m3u8_targetDuration * 850; // slower because unpack ts frames when replaced by : if(m_f_ts) m_m3u8_timeStamp = millis() + m_m3u8_targetDuration * 10; // slower because unpack ts frames Solved my problem of drop outs please check .. now its running fine with "http://air.pc.cdn.bitgravity.com/air/live/pbaudio001/playlist.m3u8"

Not work with Eldorado FM: https://eldoradolive02.akamaized.net/hls/live/2043453/eldorado/master.m3u8
Congratulations!!! You got it! This radio station now works perfectly!!! Thank you very much!!
This one I don't understand how it works... I couldn't get the link to her stream.
I've changed a few things, ELDORADO FM works for me now, can you please test it.
Perfect! Thank you very much!! I could also notice that the connection with the radios was a little faster, or is it just me?
there is a small skip in music for ID3 frame ts frames, please check "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MRETRO_Auto.m3u8", "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MNINTS_Auto.m3u8", "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MEETHI_Auto.m3u8", in above all links when ts files are changing there is small skip of song/music transition is not smooth..
I found some tags as below inbetween .ts format audio "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MRETRO_Auto.m3u8", "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MNINTS_Auto.m3u8", "https://mirchiplaylive.akamaized.net/hls/live/2036929/MUM/MEETHI_Auto.m3u8", "Service 01ATCLabs" at this positions music is jumping, plese have alook.
There are problems with the three URLs mentioned. The running time of the files is a little shorter than specified in the m3u8 as '#EXTINF:9.752381' with 9.75s. Have no idea why. What do you mean by 'Service 01�ATCLabs', that might help me with troubleshooting.
Dear Brother, Please find attached .ts file you can find in this file a tag "Service 01 ATCLabs€ü+ ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ" which you can see more than one times in a file. at this point file is skipping some music. If we can find some correction for this, I think the audio jumping will be eliminated.

Yes, I found that in the ts file.
Every 211th data packet contains this strange one "Service 01".
I have no idea what that is, and I couldn't find anything about it on the internet. The data packet with the PID 0x011
HEX 47 4[0 11] 12 00 42 ... is discarded, so it does not reach the AAC decoder. With the fix from August 21st, the stream is running quite well for me.
Yes, I found that in the ts file.
I think it’s company advertisement actlabs is the IT company which is developing streaming services. I am playing now with latest 25 aug update it looks fine. but speech is not stable after speaking its going for long loop of "slow stream, dropouts are possible" and after time out its stoping.
