hplayer plays local videos but doesn't play rtsp stream
shujaatak opened this issue · comments
I noticed that the latest hplayer plays local videos but fails and crashes when I try to play rtsp stream.
In QtCreator Application Output shows following message:

As far as I think hplayer assumes that every user must have h264_cuvid (Nvidia CUVID H264 decoder ) but this can't be true for some users. Also there should be some algorithm to stop hplayer from crashing and play video successfully if it get hardware codec error..
On my laptop I have 2 GPUs, one Intel(R) HD Graphics 5500 and one NVIDIA GeForce 820M.
I noticed that local videos play smoothly and they use Intel(R) HD Graphics 5500 but when I try to play rtsp stream, I think, hplayer trys to play rtsp video through NVIDIA GeForce 820M which I think don't have Nvidia CUVID H264 decoder so hplayer fails and crash!
Can the rtsp stream be played through Intel(R) HD Graphics 5500 just like the local videos?
According to the analysis Application Output，Could not find codec parameters，this was probably caused by UDP packet loss. You can set rtsp_transport = tcp in hplayer.conf.
I have fixed the bug that caused the application to crash due to miss codec parameters.
With rtsp_transport = tcp , now the rtsp stream works and also the application doesn't crash!
Thank you so much for improving hplayer!
BUT I noticed that while I stream rtsp video if I disconnect Wifi for about 10-20 seconds then the video automatically closes and the default media open button appears! I was expecting hplayer that it would try to reconnect the stream!
I also noticed that if I use mjpeg stream then hplayer automatically reconnect the video after reconnecting Wifi which is great!

I am going to show you the log in two pieces but, the log which is generated before disconnecting the Wifi (video is displayed smoothly):

The changes I have made in the hplayer.conf:
aspect_ratio = w:h # ORIGINAL_RATIO
rtsp_transport = tcp
retry_maxcnt = -1 # -1 means INFINITE
I noticed an another major issue in hplayer but I will post that when this issue is resolved. I don't want to create a storm of issues here :)
Now you try！
Great! now it works!
Thank you so much for making hplayer even smarter and mature!
Now I will post the other issue in a separate post.
