gstreamercheatsheet's Issues

[Feature Request] Looking for a gstreamer pipeline for encoding multiple video stream variants for an mpegts feed

Hello there,

Take this ffmpeg example which can encode an ingest (udp) to an mpegts feed with all audio & video variants muxed in:

/root/bin/ffmpeg -loglevel debug -threads 4 -filter_complex_threads 4 -fflags +genpts+nobuffer -i '$channel_udp_stream?fifo_size=9000000' -filter_complex \
"['$video_stream_id']split=3[s0][s1][s2]; \
 [s0]yadif[v0]; \
 [s1]yadif[v1]; \
 [s2]scale=w=1280:h=720:force_original_aspect_ratio=decrease:flags=lanczos,yadif[v2]" \
-bsf:a aac_adtstoasc \
-b:v:0 1500k -c:v h264_nvenc -a53cc 1 -preset slow -rc:v vbr_hq -pix_fmt yuv420p -profile:v main -level 4.0 -gpu 1 \
-b:v:1 1000k -c:v h264_nvenc -a53cc 1 -preset slow -rc:v vbr_hq -pix_fmt yuv420p -profile:v main -level 4.0 -gpu 2 \
-b:v:2 625k -c:v h264_nvenc -a53cc 1 -preset slow -rc:v vbr_hq -pix_fmt yuv420p -profile:v main -level 4.0 -gpu 3 \
-b:a:0 256k -b:a:1 192k -b:a:2 128k -c:a aac -ar 48000 \
-f mpegts \
"udp://$ip-address:$port"

The snippet above takes one ingest, uses a complex filter to create three variants that are encoded by the h264_nvenc encoder for video and three separate audio streams (already present in the input mpegts feed), and then muxes the result into an mpegts stream over udp.

How can I do something similar with gstreamer, using x264enc and faac elements, using the appropriate muxer?

[Feature Request] Looking for v4l2 source over mpegts to chunked html

This is neat. I'm hoping I can get some help, I'm looking for the gstreamer equivalent of

ffmpeg -f v4l2 -framerate 20 -video_size 320x240 -i /dev/video0 -f mpegts -codec:v mpeg1video -s 320x240  "http://example.com:8888/stream?id=s93dd21a"

The http server will be rebroadcasting this to the client's side playing on jsmpeg player https://github.com/phoboslab

Or if you have any ideas on how to use a MJPEG based pipeline.

Looking to livestream from an RTSP stream to YouTube Live

Hi, I am looking for a command that takes an RTSP stream (from an IP cam for example), and stream it to YouTube live using Gstreamer
