maegibbons 1267 Posted February 1, 2017 Share Posted February 1, 2017 Hi I record from both HDhomerun and m3u sources. Generally all works good. Thank you. Ocaasionally, due to brief internet outages the IPTV streams get "lost". But the emby copystream process does not appear to detect this. Whilst nothing more is written to the local .ts file the recording is only closed at the scheduled end time. The length of the recording is properly shown to the time that the interruption happened. Can this be improved at all so that if the bitrate goes to 0 or well below average stream rate that the copy is restarted just like what happens if i restarted the server and goes to a -1 filename? I enclose the server log from last night. 2 IPTV recordings, Elementary and Pawn Stars, started at 20:58. Both stream copies ended up being 8 minutes long. However, Emby closes the Pawn star copy at 21:32 and Elementart at 22:03. So something "internet" happened at 21:06 which killed the streams. The stream copy process did not detect this or try to recover from it. I have seen this quite a few times so thought I should bring it up as an issue.

jonthon2 0 Posted February 3, 2017 Share Posted February 3, 2017 how do you set this up for using m3u? thanks new here Link to comment Share on other sites More sharing options...
maegibbons 1267 Posted February 4, 2017 Author Share Posted February 4, 2017 If you are talking LiveTV then in the Live tv section - add a tuner of type m3u. Any issues start a new thread. Otherwise this issue i am reporting gets lost. Krs Mark Link to comment Share on other sites More sharing options...

Luke 37161 Posted February 4, 2017 Share Posted February 4, 2017 there must be a stream specific issue here. using the first url in your m3u i am not having any problems. that's both with and without recording conversion enabled. Link to comment Share on other sites More sharing options...
maegibbons 1267 Posted February 4, 2017 Author Share Posted February 4, 2017 Firstly, thanks for looking. I do not like to waste your time. I will investigate further because I literally tried one recording (which I think was Alibi Channel) and got the mkv transode issue above. Tried MP4 and got the unable to play "Active Recordings" problem. When not record-transcoding The IPTV streamcopy failure only happens infrequently when I loose internet. The issue is that It appears that the streamcopy process does not detect this. I will see if I can prove this also by cutting my internet connection deliberately. I am away for the beginning of next week but will try and test this all out and come back with definitive failure scenario's for you to test.

maegibbons 1267 Posted February 4, 2017 Author Share Posted February 4, 2017 Not sure I relayed previously that the file system time stamp stops when the streamcopy process fails. An example: Tonight i was recording "Lord of the Rings". It is now 21.11 but the last write to the .ts file was 20:31 so I know this recording has stopped. Emby still thinks it is recording and will close the file when the end timer strikes in an hour or so (and update the time stamp). However, the runtime will be about 1hr i.e truncated. The streamcopy process should be able to detect the lack of stream writes, when it happenned at 20:31, and restart the streamcopy to a "-1" file.

maegibbons 1267 Posted February 21, 2017 Author Share Posted February 21, 2017 (edited) Hi @@Luke So I revisited this after seeing a post you made on fixing muliple mkv files on transcode error. https://emby.media/community/index.php?/topic/31222-3058863651-recording-conversion/?p=423223 Before moving on to m3u's I thought I would just try to record HDhomerun streams and transcode to MKV. Even this does not work and now produces no mkv files at all. I emclose ffmpeg log herewith - ffmpeg-mkv. I then tried MP4. The transcode works. log enclosed ffmpeg-mp4-badaspect, BUT firstly you cannot play it as an "Active Recording". When it finishes, I still cannot play it in the web browser and on Fire TV the aspect ratio is wrong AND it is transcoding AGAIN - ffmpeg-firetv !!!! Recording transcoding is a complete fail here at the moment! Is there no chance of just doing some checking in the streamcopy routine to see if the input stream has stalled to address the original issue in this thread? My other concern is CPU load on transcoding at the recording stage. I sometimes record 6 streams at once which is fine when streamcopying but would be quite a load transcoding ALL input streams at the same time even if it worked and had the desired effect in detecting stream stall. Many thanks for your help. Krs Mark ffmpeg-mkv-fail.txt ffmpeg-mp4-badaspect.txt ffmpeg-firetv.txt Edited February 21, 2017 by maegibbons Link to comment Share on other sites More sharing options...
