Re: [FFmpeg-user] Need help generating field based Program Stream
Hi Bouke, Thanks for your prompt response. For me the idea is to get field based interlaced streams to test some of my implementation. Maintaining frame rate is not an issue with me. I tried with tinterlace too but not to my luck. ffmpeg.exe -y -i INPUT -c:v mpeg2video -flags +ildct+ilme -vf scale=interl=1,tinterlace=interlacex2 -b:a 256k -aspect 16:9 OUTPUT Can you please suggest if I have missed any option?

Re: [FFmpeg-user] Need help generating field based Program Stream
- Original Message - From: "kumar vikram"Hello All, I am having a Program stream which has progressive sequence. I want to convert this stream to Field based PS files. I have used the following command ffmpeg.exe -y -i INPUT -c:v mpeg2video -flags +ildct+ilme -vf yadif=1 -top 1 -b:a 256k -aspect 16:9 OUTPUT But this is creating Frame based interlaced stream. Looks like I have missed some options. Can you please help me fix this problem? Hi Vikram, What do you expect? If the source is progressive, an interlaced output will have two fields taken at the same time, thus still look progressive. If the framerate does not change, besides doing this for being compatible with streams that must be interlaced, there is no reason to do so. If you do want to change the framerate (eg from 50p to 25i, or add pulldown), there is logic. Have a look at the Tinterlace filter. hth, Bouke Regards, Vikram --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] Need help generating field based Program Stream
Hello All, I am having a Program stream which has progressive sequence. I want to convert this stream to Field based PS files. I have used the following command ffmpeg.exe -y -i INPUT -c:v mpeg2video -flags +ildct+ilme -vf yadif=1 -top 1 -b:a 256k -aspect 16:9 OUTPUT But this is creating Frame based interlaced stream. Looks like I have missed some options. Can you please help me fix this problem?
