JavaCV FFmpegFrameRecorder not saving / writing to disk
23 juillet 2013, par Israel LopezI'm using JavaCV libraries on Android, and I've been able to get the sample Recording activity working somewhat, however it is not writing to disk on my SD card.
Code : https://gist.github.com/ilopez/6046287
Log : https://gist.github.com/ilopez/6046289
Manifest : https://gist.github.com/ilopez/6046296Unlike save video using ffmpegframerecorder android question, there is no fatal exception. Just nothing is written to the sdcard.
I have tried the following filenames
/mnt/sdcard/test.flv - no IO Exception
/sdcard/test.flv - no IO Exception
/idontexist/sdcard/test.flv - IO ExceptionI have also tried to place a file in the sdcard folder, nothing saved.
I am confirming the files existence by hooking it up to my computer and viewing the SCH-I535/Card directory.
I also modified the source a bit per my previous question : How to convert ShortBuffer to Buffer[] ?

no difference between h264 and h264_cuvid
10 juillet 2020, par Ruslan AblyazovI use libav to decode an RTSP stream. I tried two code options : with auto codec selection and with hardcoded codec.


pCodec = avcodec_find_decoder (pFormatCtx->streams[p_InputVideoStreamIndex]->codecpar->codec_id);
//pCodec = avcodec_find_decoder_by_name ("h264_cuvid");

LOG (info) << "Video codec name" << pCodec->name << ". Full name:" << (pCodec->long_name? PCodec->long_name: "<null>");
</null>


The avcodec_find_decoder() function returns h264 codec. The problem is that the speed and load on the CPU when using h264 is no different from h264_cuvid. What could be the reason ? When I use h264_cuvid, the video card is loaded by 2-3% more.


Video stream : 1920x1080 25 FPS (main and high profile).
Video card : NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1).
Processor : Intel (R) Core (TM) i5-8400 CPU @ 2.80GHz.
