rtmpproto : avoid setting auth var value if null
16 mai 2014, par Reynaldo H. Verdejo Pinochetrtmpproto : avoid setting auth var value if null
Use default values if parsed variable is found not to
have any value. Avoids crashing at strlen for salt/user
on the auth call afterwards and needless NULL assignments
for the rest (default is already NULL for those).Should fix Coverity Scan issues #966644 and #966645

Is ffmpeg a good upscaler from SD to HD ?
15 août 2014, par user3928079Is ffmpeg a good upscaler to convert SD videos to HD ?
I use the AVANTI GUI. I installed it and put the ffmpeg and ffplay exe into the folder ffmpeg in the program folder. What I know is that you can only preserve the detail when you upscale from SD to HD. You don’t really gain any additional information. TV companies like Samsung, Sony, LG, Panasonic, Sharp, and others refuse to think so and push the boundaries of upscaling so that additional information can be added when the image is upscaled from SD to HD and HD to 4K and so on and so forth. I’ve run a test through the AVANTI ffmpeg GUI.
Codec : XVID to H.264
Bitrate : 1640 kbps to 6000 kbps
Resolution : 640x480 to 1440x1080
Format : AVI to M4V
Audio Codec : AC3 to AAC
Audio Bitrate : 192 kbps
Audio Frequency : 48000 Hz
Upscale method : SplineWill this upscale method work in any way with converting SD video to HD video. There’s a lot of SD content out that haven’t made the transition to, or probably never will be, HD.

Only using 1 core when I converting video to tiff sequnce file
20 août 2019, par gskMy workspace spec :
- CPU : Ryzen 1950x
- GPU : GTX 1080Ti
- RAM : 128GB
- SSD : 512GB samsung 960pro
- OS : window10
When I convert to tiff sequence file from my video(3min/mp4) CPU only used 1 core with 28 frame per sec.
If I delete-pix_fmt rgb48le
option can used more core and speed up(50 frame per sec).
but, I need changing color space for making dcp...I already tried -threads option (0,1,2,16,32,64...) but still used 1 core.
and found about GPU acceleration from other forum but I think tiff codec can’t use CUDA../ffmpeg -i test.mp4 -q:v 1 -aspect 1.85 -s 1988:1080 -an -pix_fmt rgb48le -src_range 1 -dst_range 1 -r 24 \test%010d.tiff
tiff codec don’t support multi core ?
if don’t support multi core how can I increase speed for encoding.
thank you.
