(If you?re not sure, there is a Format guide in Part three, Chapter eleven). The first thing you need to do, is select what codec you will be using, or rather: what format you want your film to end up in. Be sure to have enough space on the target drive, especially if you?ve checked ?Keep elementary streams? (see Chapter Five). Then click ?Save as.? and name your project. Click ?Open.? and navigate to that source file. #Ffmpegx avdvix movie#This could be a VOB from the DVD of your cousins wedding, a QuickTime movie or pretty much anything at all that moves or makes a sound. When you start ffmpegx, hopefully you?ve already prepared your source material. ![]() Much like the program, this is a work in progress. I?ve just been swamped with msgs and e-mails from people who want it online first, even though there is much left to be done. ![]() El Rocho of the Movie MadhouseĬomments welcome at a million to major4 for the GUI and a whole bunch of proofreading. I?ll make sure to include it in the next revision.) If you come across an expression you?re not familiar with, try looking it up in Appendix C (Glossary) before panicking or spamming us with questions. Once all the binaries and the main program is installed, you?re ready to go. You no longer need to understand all that much of the underlying processes to make good DivX/VCD/SVCD (to name but a few) in a reasonable amount of time.ĭownload the latest version of ffmpegx from major4, and follow the installation instructions. #Ffmpegx avdvix manual#This is a User Manual for the ffmpegx gui, a graphical user interface through which you can access powerful (and remarkably cost-efficient) UNIX tools for video/audio conversion. It's better on a newer computer, but soft decoder is better.ĭxva2_retrieve_data_call and sws_swale consume lot of time when hwaccel is enabled. Problem solved i didn't check if I got a picture before retreiving it.īut the performance are very poor on my desktop cmputer (intel core i5 650, 4GB RAM, ATI HD5800) it consumes 5% more of CPU, 3 times more RAM, and lot of corrupt frame. I got my picture but with lot of artefact and after few seconds I got a segmentation fault in dxva2_retrieve_data_call(pCodecCtx, pFrame, &gotPic, &packet) I tried to convert it sws_scale(img_convert_affic, pFrame->data, pFrame->linesize, 0, pCodecCtx->height, pFrameRGB->data, pFrameRGB->linesize) Īnd copy the buffer to a Qimage LastFrame=QImage(w,h,QImage::Format_RGB888) įor(int y=0 ydata+y*pFrameRGB->linesize,w*3) I decode the packet with avcodec_decode_video2(pCodecCtx, pFrame, &gotPic, &packet) Īnd I'm getting my decoded frame with dxva2_retrieve_data_call(pCodecCtx, pFrame, &gotPic, &packet) Hello, I use this post to help me in my HW acceleration with FFMPEGįailed to execute: 0x80070057, when decoding video via ffmpeg with dxva2 I have never use Direct X, do I need Direct X knowledge, or ffmpeg with -enable-dxva2 and -enable-hwaccel=h264_dxva2 care of everything ? I have to build FFMPEG with -enable-dxva2 and -enable-hwaccel=h264_dxva2 ? or Zeranoe build #Ffmpegx avdvix how to#I really want to try hardware acceleration with DXVA2 to see if I can get better performance especially in slowest CPU.īut i really don't know how to proceed. #Ffmpegx avdvix code#I code under windows with Qt.I need the lowest latency as possible and the best result I can get is done whith :īut with "slow" CPU I have lot of latency if the bitrate is too high or it can't handle 1080p. I've made a player for IP camera (fullHD H264) with FFMPEG ![]()
