Problem with recorded flv video - bigger video cant play and only freeze at the beginning (play only about 0.5s)

[vavdav]

Hello, I am recording from flash. Sometime recorded video is broken and cant be played fully. Only about 0.5s is played and then video is restarted/ended (depend on player). In bsplayer I can jump over 0.5s by seek bar and then video is played to the end.

Flash side setting: 845x480 @24fps video keyframe interval 24 videoBandwidth 430000 audio codec NELLYMOSER audio encode quality 7 using command: ns.publish("testfile", "record");

Serverside setting rtmp { server { listen 1935; timeout 30s; access_log /var/log/nginx/rtmp.log; application myapp { live on; record all; record_max_size 200M; record_max_frames 1000000;
record_path /MP4; on_publish http://localhost/publish; on_play http://localhost/play; on_record_done http://localhost/record_done; } } } Please can u help me with nginx server setting, what is best for recording video. For best video quality

Iam newbie to nginx rtmp, before I used RED5. Thanks for help

edit: here is example with that issue https://dl.dropboxusercontent.com/u/21299530/test_2013-9-13_20-31-36.flv here it is putted to player: http://invisible.wz.cz/nginx/prehravac.html

Looks like 0x341 bytes are lost from the flv. Need debug log to debug the problem.

Flv tag offsets:

here is log: https://dl.dropboxusercontent.com/u/21299530/rtmp.log.1

Its not what u need I think... I have to run nginx with debugging, is it true? I will write to my nginx provider

[arut]

It's access log, not error.log. See this link for setting up debug log: https://github.com/arut/nginx-rtmp-module/wiki/Debug-log

here is problem video: https://dl.dropboxusercontent.com/u/21299530/test_2013-9-14_19-39-56.flv here is log: https://dl.dropboxusercontent.com/u/21299530/error.log actual config: https://dl.dropboxusercontent.com/u/21299530/nginx.conf

it looks like the problem is caused by setting NELLYMOSER audio codec. When I switch to SPEEX audio codec then it looks it is working. But problem is when I want to play this video in flash video player. Sound is really bad, almost no sound and video is slowed - not fluent. Sound is not synced with video correctly

I created video with SPEEX codec. Here is: https://dl.dropboxusercontent.com/u/21299530/test_2013-9-14_21-13-9.flv but in vlc it freeze after 4s of playing. In BSPlayer it play all. But both without sound.

here is flv video in flash video player http://invisible.wz.cz/nginx/prehravac.html

If you record speex in flash then turn off silence detector (set its level to zero) to make speex sound ok.

[arut]

Generally it didn't look like audio codec problem. The first file has broken data, namely video data.

thank you. I edited some parameters and now it works. Sound is recorded with video. Need to get better quality, if it will be possible. I will do more tests to test it if is it really ok.

biggest problem was NELLYMOSER audio codec and video.setQuality(430000, 0); - some bandwidth and zero video quality

now I had some problem with video and sound. sound was late. And some error apear:
