use FFmpeg+x264+SCR to record, why no video data can be read after 8 minutes ?

[luckywan]

hi,rdp: I have Encountered a problem, i use ffmpeg + x264 to encode the video data and aac-eld to encode the audio data,the beginning,it works normally,but about 8 minutes later,i use following : av_read_frame(pFormatContext_In, &pPacket) ,AVMEDIA_TYPE_VIDEO == pFormatContext_In->streams[pPacket.stream_index]->codec->codec_type , no video data to read ,only the audio data can be read.

the following is my program code: while (av_read_frame(pFormatContext_In, &pPacket) >= 0) {
if (pPacket.stream_index == videoStream) // after 8 minutes , no videoStream { ... } else if(pPacket.stream_index == audioStream) // audioStream works normally { ... } }

can you help me? Best Regards!

yes,audio data can be read fine,but video data is none.

[luckywan]

while(!exitcapturescreenthread){ if (av_read_frame(pFormatContext_In, &pPacket) >= 0) //read audio and video data {

if (pPacket.stream_index == videoStream) // after 8 minutes , video data is none { ... } else if(pPacket.stream_index == audioStream) // only audio data can be read fine { ... } } }

The following is my log. V is video data ,the number is frame number. 17155 frame later, i can't read the video data.i think it is not fine from 17141 to 17155,it is only 15 frames,other second is about 30 frames. [17:49:51] V: 17111 [17:49:51] V: 17112 [17:49:51] V: 17113 [17:49:51] V: 17114 [17:49:51] V: 17115 [17:49:51] V: 17116 [17:49:51] V: 17117 [17:49:51] V: 17118 [17:49:51] V: 17119 [17:49:51] V: 17120 [17:49:51] V: 17121 [17:49:51] V: 17122 [17:49:51] V: 17123 [17:49:51] V: 17124 [17:49:51] V: 17125 [17:49:51] V: 17126 [17:49:51] V: 17127 [17:49:51] V: 17128 [17:49:51] V: 17129 [17:49:51] V: 17130 [17:49:51] V: 17131 [17:49:51] V: 17132 [17:49:51] V: 17133 [17:49:51] V: 17134 [17:49:51] V: 17135 [17:49:51] V: 17136 [17:49:51] V: 17137 [17:49:51] V: 17138 [17:49:51] V: 17139 [17:49:51] V: 17140 [17:49:52] V: 17141 [17:49:52] V: 17142 [17:49:52] V: 17143 [17:49:52] V: 17144 [17:49:52] V: 17145 [17:49:52] V: 17146 [17:49:52] V: 17147 [17:49:52] V: 17148 [17:49:52] V: 17149 [17:49:52] V: 17150 [17:49:52] V: 17151 [17:49:52] V: 17152 [17:49:52] V: 17153 [17:49:52] V: 17154 [17:49:52] V: 17155 17:49:53 ------> from here, no video data can be read . [17:51:10] V: 17156 [17:51:10] V: 17157 when i set exitcapturescreenthread= true to exit the while() statement ,i receive two frame video data. so, what is the cause of the problem? my code or ffmpeg or scr ? tks!

my last_init_config_was is default/from reg read config as: 768x1366 -> 768x1366 (0 top 768 bottom 0 l 1366 r) 60fps, dedupe? 0, millis between dedupe polling 10, m_bReReadRegistry? 0 hwnd:0 my computer is thinkpad T440 ,i5 cpu ,8G RAM.

if you record with ffmpeg command line does it work ok?

It's ok with ffmpeg command line.

[rdp]

what if you capture just video in your own project there? does it continue working?

No, the result is the same, several minutes later, no video data can be read.

[luckywan]

is my program code ok in this way? while(!exitcapturescreenthread){ if (av_read_frame(pFormatContext_In, &pPacket) >= 0) //read audio and video data {

if (pPacket.stream_index == videoStream) // after 8 minutes , video data is none { ... } else if(pPacket.stream_index == audioStream) // only audio data can be read fine { ... } } }

[rdp]

I'm not sure about the code, if it starts working it's probably OK. Is the computer display going to sleep per chance? what about receiving from gdigrab instead?
