• Appium screen recording doesn't work on simulator

  31 août 2022, par Oks

  I'm running automation tests on simulator and trying to record screen but it crashes on line driver.start_recording_screen()
I'm using Python for testing and Flutter for client side.

  


  self.utils.driver.switch_to_native_context()
driver.start_recording_screen()

• av_interleaved_write_frame() : Cannot allocate memory, Error writing trailer of udp

  30 août 2022, par Technical_Union7716

  I'm transcoding from udp input to mpegts udp output. After several hours ffmpeg used all ram memory. I don't know where the problem is.

  


  Command :

  


  ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i "udp://239.100.1.5:1234?fifo_size=1000000&overrun_nonfatal=1" -map i:0x100 -map i:0x101 -vf 'scale_vaapi=w=720:h=576,hwdownload,format=nv12,fps=25' -c:v mpeg2video -b:v 5000k -minrate 5000k -maxrate 5000k -muxrate 7000k -pcr_period 40 -flags:v +ildct+ilme -top 0 -aspect 16:9 -c:a mp2 -b:a 192k -c:s copy -mpegts_service_id 1 -metadata service_name="Transcoded" -metadata service_provider="HD to SD" -f mpegts "udp://239.120.1.2:7006?pkt_size=1316&bitrate=12000000"

• FFmpeg no such filter 'tpad'

  29 août 2022, par Zeek Aran

  I have a simple gif. I am not in general familiar with FFmpeg commands so I assume it's just my syntax being wrong, but what I'm using is straight from an answer here so I thought it would work.

  


  I'm trying to add a delay on the last frame of my gif.

  


  ffmpeg -i out.gif -vf tpad=stop_mode=clone:stop_duration=2 out2.gif


  


  But I'm getting this when I try it :
