Cannot change audio_stream_id and video_stream_id

[mibuhari]

I couldn't succeed in running the following command in casparcg ADD 1 STREAM "udp://127.0.0.1:9250?pkt_size=1316" -vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=302:168 -audio_stream_id 301 -video_stream_id 310

Is the above correct? The output of ffprobe shows the stream as running with pid 256 (0x100) and 257 (0x101)

Thanks in advance.

No, you have to omit all - signs. Available parameters from command line are:

• vcodec,
• acodec,
• separate-key
• vrate,
• arate (both in kbps),
• options (may be in quotation marks),
• pixel-format,
• output-metadata (also may be in quotation marks),
• audio-metadata,
• video-metadata,
• audio_stream_id,
• video_stream_id

So in your case correct command syntax is: ADD 1 STREAM "udp://127.0.0.1:9250?pkt_size=1316" vcodec libx264 audio_stream_id 301 video_stream_id 310 options="preset=ultrafast,tune=zerolatency,crf=25"

Currently there is no way to freely apply filter, and scaling is available on current release, but limited only to formats defined in CasparCG (PAL, 1080i5000 etc.)
