Please provide the actual command line that you tested (without

[FFmpeg-user] Color Difference on ffmpeg Outputs
I noticed a color difference between my master video file and the
output file from ffmpeg. My master file is Apple ProRes 422 HQ .mov. I
converted it to Apple ProRes 422 (not HQ).mov, using ffmpeg. There is
a significant color difference on the converted file that is
noticeable in the graphics.
The RGB values are: Master file: R:221 G:49 B:42 Converted file:
R:202 G:24 B:32. All lower numbers on the converted file. I'm
attaching a screenshot to show the difference. Is there a filter or
something that I can add to this command line to solve this?
mkdir outputs
for f in *.mov; do ffmpeg -i "$f" -c:v prores -c:a pcm_s24le
"outputs/${f%.*}.mov"; done

[FFmpeg-user] Usage of scte35 attributes in ext-x-daterange tag
Hi, I have come across some issues while working with EXT-X-DATERANGE tag. Date range tag has some attributes SCTE35-CMD, SCTE35-OUT, SCTE35-IN which are related to splicing. If I understand correctly, splicing is used in TS streams for inserting transport streams on transport packet boundaries; So from hls point of view, do you think we need to take any explicit action which may be required by demutiplexer/decoder(e.g. SCTE35-CMD attr value)? Moreover I believe that in case EXT-X-DATERANGE tag is encountered, hls needs to specify discontinuity to continue the playback of ads. But in case EXT-X-DATERANGE tag with SCTE35 attributes, since the stream is already prepared in such a way using splicing that it is more like a continuous bitstream, even discontinuity is not needed. Correct me if I am wrong. Can you please sugegst what can be the usage for SCTE35-CMD, SCTE35-OUT, SCTE35-IN attributes in HLS? Thanking you in advance Regards, Vikram ___ 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".
