Filter codecs preferences on transceiver direction #3018

henbos · 2024-11-07T12:48:57Z

As decided by the WG, this PR implements Proposal A at TPAC, i.e:

A sendonly transceiver can prefer sendonly codecs.
A recvonly transceiver can prefer recvonly codecs.
A sendrecv transceiver can only prefer codecs that we can both send and receive with. If you want to use both sendonly codecs and recvonly codecs you need to have two transceivers.

This is supported via filtering based on RTCRtpTransceiver.direction. In addition, the case where filtering results in an empty codec preferences this is treated as "no preference" as per Proposal A at Virtual Interim.

We should avoid competing normative language with JSEP. One way might be to put explanations in non-normative notes.

@jan-ivar Have I addressed your feedback? If you could take a look before the editor's meeting

LGTM. I might add another note to cover the surprising case if the answerer receives a recvonly offer: in this case it's too late for the answerer to use setCodecPreferences to set what to send, and they need to use setParameters instead.

According to PR[1], setCodecPreferences() should accept any codec that is *either* in in RTCRtpSender.getCapabilities() *or* RTCRtpReceiver.getCapabilities(); the actual filtering happens when the SDP is generated based on the transceiver direction. This makes it possible for a sendonly transceiver to offer a sendonly codec and for a recvonly transceiver to offer a recvonly codec, as opposed to forcing that all codecs must be receive-capable at createOffer() time which is the old and currently implemented behavior, hence the failing test. (In the old model, pc1 would be forced to not have any preferences and pc2 be forced to call setCodecPreferences() before createAnswer() on behalf of pc1 in case that pc1 is sendonly.) Due to the limitation that on a local page both pc1 and pc2 have the same capabilities, the remote SDP is modified to make pc1 think that pc2 supports the codec being negotiated in the other direction. Because getCapabilities() is device-specific, we skip the tests (using [PRECONDITION_FAILED]) if the necessary capabilities (= unidirectional H264) is not supported but the tests work e.g. on MacBook M1 Pro.

… WPT using H264., a=testonly Automatic update from web-platform-tests Add unidirectional codec test support in WPT using H264. According to PR[1], setCodecPreferences() should accept any codec that is *either* in in RTCRtpSender.getCapabilities() *or* RTCRtpReceiver.getCapabilities(); the actual filtering happens when the SDP is generated based on the transceiver direction. This makes it possible for a sendonly transceiver to offer a sendonly codec and for a recvonly transceiver to offer a recvonly codec, as opposed to forcing that all codecs must be receive-capable at createOffer() time which is the old and currently implemented behavior, hence the failing test. (In the old model, pc1 would be forced to not have any preferences and pc2 be forced to call setCodecPreferences() before createAnswer() on behalf of pc1 in case that pc1 is sendonly.) Due to the limitation that on a local page both pc1 and pc2 have the same capabilities, the remote SDP is modified to make pc1 think that pc2 supports the codec being negotiated in the other direction. Because getCapabilities() is device-specific, we skip the tests (using [PRECONDITION_FAILED]) if the necessary capabilities (= unidirectional H264) is not supported but the tests work e.g. on MacBook M1 Pro.

If this sticks we can try replacing that with third_party/blink/web_tests/platform/win11-arm64/ specific -expected.txt files but let's make sure the baseline test coverage is not reverted first. [1] https://ci.chromium.org/ui/p/chromium/builders/ci/win11-arm64-rel-tests/b8730008657167826369/overview Original change's description: > Add unidirectional codec test support in WPT using H264. > > According to PR[1], setCodecPreferences() should accept any codec that > is *either* in in RTCRtpSender.getCapabilities() *or* > RTCRtpReceiver.getCapabilities(); the actual filtering happens when the > SDP is generated based on the transceiver direction. > > This makes it possible for a sendonly transceiver to offer a sendonly > codec and for a recvonly transceiver to offer a recvonly codec, as > opposed to forcing that all codecs must be receive-capable at > createOffer() time which is the old and currently implemented behavior, > hence the failing test. (In the old model, pc1 would be forced to not > have any preferences and pc2 be forced to call setCodecPreferences() > before createAnswer() on behalf of pc1 in case that pc1 is sendonly.) > > Due to the limitation that on a local page both pc1 and pc2 have the > same capabilities, the remote SDP is modified to make pc1 think that > pc2 supports the codec being negotiated in the other direction. > > Because getCapabilities() is device-specific, we skip the tests (using > [PRECONDITION_FAILED]) if the necessary capabilities (= unidirectional > H264) is not supported but the tests work e.g. on MacBook M1 Pro. > > [1] w3c/webrtc-pc#3018 > > Bug: chromium:379551577 > Change-Id: I4e1ce5371db66de83d42cbd2ba2eca5d703661d3 > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6054227 > Reviewed-by: Harald Alvestrand <htachromium.org> > Commit-Queue: Henrik Boström <hboschromium.org> > Cr-Commit-Position: refs/heads/main{#1389353} Bug: chromium:379551577, chromium:381378075 Change-Id: I54608d45d259bafde375fdb8da371ca45e69e5f3 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6054131 Auto-Submit: Henrik Boström <hboschromium.org> Reviewed-by: Harald Alvestrand <htachromium.org> Commit-Queue: Harald Alvestrand <htachromium.org> Commit-Queue: Henrik Boström <hboschromium.org> Cr-Commit-Position: refs/heads/main{#1389697} -- wpt-commits: b6af0e5b8ce153c42623baac8e33bb341e33aa18 wpt-pr: 49438 UltraBlame original commit: fcb351942a5c6746bc7320c52069e801bda35699
