checkasm : x86 : properly save rdx/edx in checked_call()
16 août 2015, par Henrik Gramnercheckasm : x86 : properly save rdx/edx in checked_call()
If the return value doesn’t fit in a single register rdx/edx can in some
cases be used in addition to rax/eax.Doesn’t affect any of the existing checkasm tests but might be useful later.
Also comment the relevant code a bit better.

FFMPEG : how to save input camera stream into the file with the SAME codec format ?
19 janvier 2014, par user3211926I have the camera-like device that produces video stream and passes it into my Windows-based machine via USB port.
Using the command :
ffmpeg -y -f vfwcap -i list
I see that (as expected) FFmpeg finds the input stream as stream #0.
Using the command :
ffmpeg -y -f vfwcap -r 25 -i 0 c:\out.mp4
I can successfully save the input stream into the file.
From the log I see :
Stream #0:0 : Video : rawvideo (UYVY / 0x59565955), uyvy422, 240x320, 25 tbr, 1k tbn, 25 tbc
No pixel format specified, yuv422p for H.264 encoding chosen.So, my input format is transcoded to
yuv422p
.My question :
- How can I cause FFmpeg to save my input video stream into out.mp4 WITHOUT transcoding - actually, to copy input stream to output file as close as possible, with the same format ?
