playback recording fails

[TuxTiger]

Hello,

I am using NextPVR to record IPTV streams. Some streams, although correctly recorded, fail to playback in the browser.

log:
Executing: ffmpeg -y  -i file:"path/file.ts" -map_metadata -1 -threads 0 -ignore_unknown  -map 0:v:0?  -map 0:a:0 -map -0 -codec:v:0 libx264 -pix_fmt yuv420p -preset superfast -crf 23 -vf yadif=0:-1:0 -b:v 2000000 -maxrate 2000000 -bufsize 4000000 -vsync vfr -profile:v high -level 41 -force_key_frames "expr:gte(t,n_forced*3)" -s 1280x720  -c dvbsub -flags -global_header -sc_threshold 0 -codec:a:0 aac -strict experimental -ac 2 -ab 192000 -hls_time 5 -start_number 0 -hls_list_size 0 -y "/var/opt/nextpvr/web/temp/blabla-de791f6502164ece95104b9d27e784a8.m3u8"

2022-03-11 16:45:37.524 [DEBUG][61]  [FFMPEG]: [mpegts @ 0x557ba6a12d40] Could not find codec parameters for stream 0 (Video: h264 ([27][0][0][0] / 0x001B), none): unspecified size
2022-03-11 16:45:37.524 [DEBUG][61]  [FFMPEG]: Consider increasing the value for the 'analyzeduration' and 'probesize' options

PS: I anonymized some values...

Question: can I change some setting so that ffmpeg will work with option "-probesize 512000" for example? Default ffmpeg probesize is too short for my source files...

Regards and thanks for this great piece of software!

Unfortunately you didn't upload the zipped logs but I suppose the problem with these IPTV recordings is that NextPVR transcodes them when it might not be necessary. I have asked sub if he could change that.

Personally I strongly recommend using direct play clients for recordings, and if you prefer the browser client there is an option to post process recording into formats the web browser can direct play.

TuxTiger, can you supply a short sample recording that exhibits the problem?
